Risen solar panels: 5 things you need to know before investing

Risen Solar Panels Powering the Merredin Solar Farm with blue sky on the horizon

Risen solar panels are the module of choice used within Western Australia’s iconic Merredin Solar Farm, a national utility-scale leader in production output. However, to determine which Risen solar panels are ideal for your project, greater insight is essential—the researched investor you want the Risen Energy facts, less the spin. Your focus is energy security when choosing a particular solar panel, and five essential elements deliver a better general insight to reassure a solar energy investment decision.

Most will consider whether Risen solar panels are a BNEF Tier-1 ranked module brand. Even though such ranking offers little insight into individual product quality, the Bloomberg New Energy Finance module tiering system provides manufacturer bankability rankings for large-scale solar projects assisting warranty assurance for financiers. As it turns out, this is advantageous for rooftop solar module purchasers when considering brand strength and long-term warranty validity.

The sixth most voluminous BNEF Tier-1 solar panel manufacturer (Q1, 2023, 39 companies listed), Risen Energy is fast becoming synonymous with modern high-efficiency module designs while offering exceptional value. However, broader research is required to know which particular Risen solar panels are ideal for your rooftop solar project.

Even though Risen have many module variations, most currently available in Perth can be refined to one base residential module variant. From here, higher Watt solar panels are merely achieved by adding more cells and, in turn, increasing weight and loading on the structure beneath. Ensuring a solar panel weighing 20-21 kG is a good measure of discerning the module difference if sizes become confusing.

	Titan S	415 W	21.6%	-0.34%	21 kg	Datasheet

Risen Titan S (415 W): The most popular of the current Titan series provides an improved yield for rooftop solar arrays and superior affordability. Alternative models exist for different purposes. However, the Risen Titan S 415 W (120 cells) is by far the most popular for residential rooftops. Larger and alternative formations exist (bifacial/ all-black/ 130+ cells), although this is the base design on which the technology is founded.

Enphase has been building micro-inverter technology for over a decade, and they’re good at it too. Mild shading to a particular panel in an array, micro inverters ensure only the affected solar panels are isolated while the remaining modules operate at peak performance. The most significant drawback of an Enphase inverter system is the cost compared to a string inverter system. As a guide, an Enphase 6.6kW system is approximately $3000 more than a Fronius inverter system. However, this cost includes energy consumption monitoring features.

What we love: We like data, and module-level performance monitoring combined with the Enphase user-friendly monitoring portal is the most remarkable feature of Enphase that a string inverter can’t do unless adding optimisers such as Tigo.

Extracted from: Charge Up WA business EV charger rebate guidelines (PDF download)

Example 1: Small Business installing an EV charger for employee use.

A small business owner (applicant) in the Greater Perth area with ten employees wishes to install one EV charger (with two ports) for staff use. The applicant or its employees may or may not already drive an EV. The applicant has several reasons for installing an EV charger:

To make it easier to replace existing business vehicles with EVs
To provide a workplace benefit for staff
To communicate to customers that the business cares about taking action on climate change

Opening hours for the business are 9 am to 5 pm on weekdays only, and EVs used or owned by employees are expected to largely remain on site during the working week. The applicant can therefore be confident that a significant proportion of the EV charging will occur during the day. The applicant obtains a quote from Perth Solar Warehouse and successfully applies for the grant.

Item	Total Cost	Business Covers	Grant Covers
Charger: One 7kW charger with two ports	$3000	$1500	$1500
Installation costs for one 7 kW charger	$4000	$2000	$2000
Software subscription for two years, $180 per annum, per port	$720	$180	$540
Total Cost	$7720	$3680	$4040

In this scenario, the applicant must be able identify a suitable location for a wall-mounted charger that is between two parking bays.

Example 2: A charity intends to install EV chargers at three sites within the Greater Perth area

The charity intends to install EV chargers at three sites to make replacing existing fleet vehicles with EVs easier. The charity does the following:

Arranges a detailed quote for each site – a quote for each site is needed as funded items (EV charger hardware, software and installation) are assessed on a site-by-site basis. Perth Solar Warehouse provides an all-in-one quote.
With the help of Perth Solar Warehouse, the charity considers which vehicles will use these chargers, how long vehicles are stationary, and whether they can charge at times other than the evening peak.

– The charity decides to install two 7 kW chargers at site 1, which will predominantly be used for overnight charging

– At the two other sites, the charity decides to install two 22 kW chargers to be used to provide daytime charging for pool vehicles

Installation at these sites represents the first phase of the charity’s electrification journey with Perth Solar Warehouse. The charity considers current and future software requirements and hardware compatibility when making choices for this phase.

Item	Total Cost	Charity Covers	Grant Covers
Chargers at site 1: Two 7kW chargers	$4000	$2000	$2000
Installation costs for site 1	$8000	$4000	$4000
Chargers at site 2: Two 22kW chargers	$7000	$3500	$3500
Installation costs for site 2	$10000	$5000	$5000
Chargers at site 3: Two 22kW chargers	$7000	$3500	$3500
Installation costs for site 3	$12000	$7000	$5000
Software subscription for two years	$4000	$1000	$3000
Total Cost	$52000	$26000	$26000

The WA Government has contributed less than 50 per cent of the installation costs for site 3 because of the funding cap of $5,000 for installation costs for each site (in the metropolitan area). However, because 75 per cent of the software subscription costs are funded, the total Government contribution is still a 50 per cent share of project costs

Example 3: Café owner in regional Western Australia intends to install
EV chargers to increase its patronage

The owner of a café, which operates from 7 am to 3 pm in a regional area (applicant), intends to install an EV charger to draw more visitors to the business. The applicant engages Perth Solar Warehouse to provide a quote and assist with the grant application. The following considerations apply:

The cafe does not have a suitable location to install a less expensive wall-mounted charger, so the applicant has decided to install pedestal-mounted (free-standing) chargers.
The applicant does not own the car park where the chargers will be installed, so arranges the completion of a landowner consent form.
The applicant wants users to pay a fee and has chosen a software package to enable this. By working with PSW trusted EV software suppliers, Perth Solar Warehouse ensures that the EV charger selected is compatible with the software to be used.
The applicant wants EV drivers to know about its charger and ensures it is listed on an online charging map.

The applicant can get many quotes, but time is short. Your path of least resistance to reach out to Perth Solar Warehouse for a WA business EV charger rebate easy application package. Your grant is later approved. The grant funding contributions to the project costs are summarised in the following table.

Item	Total Cost	Cafe Covers	Grant Covers
Chargers: Two 22kW chargers (each with 2 ports)	$16000	$8000	$8000
Installation costs	$12000	$6000	$6000
Software subscription for two years, $250 per annum, per port	$2000	$500	$1500
Total Cost	$30000	$14500	$15500

There is no funding cap on grant contributions for EV chargers and software, 50 per cent and 75 per cent of these costs, respectively have been covered by the grant

As the café is located in regional Western Australia the regional co-funding cap on installation of $10,000 applies. The grant can meet 50% of the total installation costs, which is $6,000 (compared to a maximum of $5,000 for charger installations in the Greater Perth area)

You can sift for days on end, although less than 80 of those are left. Or you can go straight to the all-in-one solution to access the 2023 WA business EV charger grant. Your locally based electric vehicle charging infrastructure, software and installation package.

Advantages of Solar Analytics over conventional solar software

Solar Analytics Special by Perth Solar Warehouse

Considering a Solar Analytics energy monitoring option when your existing solar inverter has a free monitoring software solution seems superfluous to your requirements. Therefore, as monitoring software, what benefits does Solar Analytics offer towards monitoring your energy system? One truth we can’t avoid is that energy is digital from 2023, and the hype surrounding this particular software is real.

A lot has changed since the initial release of Solar Analytics. Equally, what you can expect from this Australian energy software pioneer has changed. Let’s not waste your time. At the bottom of this post are the 8 advantages of Solar Analytics over conventional inverter included software. However, all of this may make little sense without understanding what has changed since the original version.

The original concept positioned Solar Analytics as an arbitrary platform built to operate independently with your solar energy system and power supply. Arbitrary as the software would leverage a small independent device (hardware) that would be mounted within your switchboard and connected to the internet via a 3G/4G cell connection, ensuring system monitoring without loss of WiFi interference.

Extending the independent nature of the monitoring platform, reading energy data was achieved through CT (Current Transformer) clamps connected around the cables where energy monitoring was to occur. Completing the installation, a simple hardwired power supply connection within a switchboard was required to energise the Solar Analytics device.

Users would receive independent solar energy system performance analysis based on Bureau of Meteorology data for the local region, advanced cost-saving analysis using local energy supply tariffs, independent insight identifying system errors through its proprietary algorithm and detailed energy profile insight. An overall feature-rich and user-friendly energy monitoring software that, in the simplest terms possible, kept a solar energy system honest, even without a stable internet connection. Game changing.

Solar Analytics is a software company, and in such a scenario, it’s often better to concentrate on software-related developments than procuring hardware. Therefore what you can expect has changed slightly. Solar Analytics has secured deals with selected energy hardware manufacturers for Application Programming Interface (API) access to populate energy data through the Solar Analytics platform.

WiFi connectivity has become more stable over the last decade, so the need for a cellular connection is an avoided expense. Migrating to API data (minus the additional hardware) provides an installation and device cost-saving for users to engage with the Solar Analytics software. Conversely, users receive only the information that the hardware can report. Therefore, if the system is just solar (inverter only), the information within is purely solar production-based. Production-based monitoring powered by Solar Analytics deeper monitoring insight ensures your system performs as promised from the point of sale.

Solar Analytics shot to popularity as an affordable advanced energy insight solution simplified for every day users. Delivering the need-to-know information on a user-friendly dashboard while reporting independently of an energy system through self-learning (AI) and other local data sources not integrated with basic solar monitoring tools. The more digestible the information, the more users could react better to invoke bill savings success.

Original Solar Analytics: In the past, the average initial cost of Solar Analytics from Perth Solar Warehouse, including installation and a residential subscription package, ranged from $790 to $1590. A breakthrough cost, considerably less than previous independent energy monitoring solutions. Although, still a significant investment for many to consider after already purchasing a solar energy system.

Many installation types are different and not always in range of a WiFi connection. The cellular capabilities of the original Solar Analytics concept was a strength in many instances. If leaning toward the original, this monitoring solution remains available using the Wattwatchers Auditor range, purchased here. Wattwatchers Auditor requires installation by a suitably qualified electrician plus Solar Analytics subscription costs.

Perth Solar Warehouse no longer provides this service.

New Solar Analytics: Purchase a Solar Analytics compatible inverter through Perth Solar Warehouse, and we will activate Solar Analytics advanced energy monitoring access at no cost. Activation facilitates an initial free subscription period with subscription options starting from $40 per year beyond the trial period—digitalising energy, so it has the potential to rescue up to $400+ in extra savings annually.

Given that new Solar Analytics is only as capable as the hardware installed, the best thing you can do to see what the software can do for you is to add an energy consumption monitor while installing your Solar Analytics enabled inverter.

A termed ‘smart meter’, ‘energy monitor’ or ‘power sensor’ that works alongside your solar inverter, which monitors grid supply power flow (import and export) independent of your Supply meter. Energy monitors are most cost-effective when purchasing your solar energy system as a portion of the installation cost can be absorbed.

Higher-power solar panels (475W+) aren’t better, they’re bigger

Higher power solar panels installed on a factory roof with an orange sunset setting in the background

From 2023 with solar module efficiencies ranging from 21-22%, higher-power solar panels (greater than 415 – 440 W) are not better, they’re just bigger, a lot bigger. Oversized solar panels present a heavier, cumbersome build, designed for purposes other than Australian residential rooftops. Therefore, why do companies sell these modules? The answer, marketing hype to have you believe you are buying better—your first red flag.

Unlike other electrical purchases where a higher-power product for a similar price offers a potential advantage over that of lesser power (speakers, microwave, drill etc.), the same can not be said for higher-power solar panels. With equal efficiency, higher-power solar panels occupy the same rooftop surface area required to fulfil the system generation capacity (e.g. 6.6, 10 or 13 kW) as their lower-power counterparts.

Unfortunately, many consumers perceive high power output as a technology advantage, while deceptive vendors leverage knowledge gaps. There is a purpose for higher-power solar panels, and in most instances, it’s not your residential rooftop.

Manufacturers add additional rows of cells to make solar panels more appealing for specific project designs. Such a result alters electrical characteristics of the solar panel, affecting the system design. However, the more you stray away from popular residential electrical characteristics, the harder it is to incorporate future technology or maintenance (DC-coupled technology, inverter replacements etc.). Therefore, what may initially be appealing has the potential to become an ongoing hindrance in a residential-type scenario.

Datasheet examples updated from JinkoSolar.com.au 16/01/2023.

In this instance, the technology is not unique. The higher-power solar panel of the same brand will occupy the most surface area per/m² compared to its lower-power counterparts due to the lowest efficiency. However, the differences would be virtually unnoticeable at only a 0.59% efficiency difference. As the solar panel expands its cell capacity a significant weight increase occurs. Weight increase should be accounted for in the system design, but is often neglected, resulting in adverse downstream issues.

From 2022/23, leading solar panel manufacturers are building 600 W+ solar modules. One must query, though, why are these ultra-high-powered solar panels not marketed to homeowners if the highest-power solar panels are the most advanced? Deceptive marketers would if they could. Although, the electrical characteristic mismatch and dimensions become too extreme to be a plausible solution.

In the below video, LONGi Solar, the world’s largest manufacturer (BNEF Tier 1, Q4 2022) identify with the Hi-MO 4 range that different module outputs suit specific purposes, with the higher-power solar panels being achieved with an increased cell quantity and better suited towards C&I projects. Same panel, different dimensions with altered electrical characteristics.

Industry: Load bearing compatibilities. The ability to support the additional weight of a higher-power solar panel on the selected mounting location is often a non-issue in industrial scenarios, thanks to reinforced load-bearing capabilities.
Industry: Reduced captial expenditure. Through minimising the installation time by mounting fewer solar panels. A result that, in turn, can positively affect the capital outlay required. Considering nearly all solar installations are often priced per/watt, such is a less likely case.
Industry: Reduced associated infrastructure costs. Particular module-level optimisation and monitoring requirements at a reduced cost.
Residential: Potential design flexibility. In circumstances where selected roof faces are less than accommodating, achieving electrical design flexibility with higher-power solar panels over the equal counterpart of a lower-power solar panel can be advantageous.
Residential: Certain installation limitations. Specific higher-power solar panel designs can assist where bearer spacings are wider on specific roof types. However, it's important to ensure additional reinforced support is installed to accommodate a more centralised weight distribution.

Non-invasive quoting. Discover the hassle-free solar quotes we’re renowned for.

Residential: Concentrated weight distribution. A concentrated and centralised weight distribution is more likely to upset the structure's integrity over time if installed similarly to the reduced-dimension counterpart.
Residential: Vendor installation savings. It's often cheaper for the company from which you are purchasing. Unlike industry, residential solar companies without in-house installers often pay sub-contractors per solar panel—fewer panels = reduced installation costs.
Residential: Limited surface area potential. Or a reduced effectiveness towards space utilisation. Comprised of angled hips and valleys, Australian residential rooftops are often space-limited. Due to increased dimensions, higher-power solar panels present increased challenges for trickier rooflines.
Residential: Service limitations. The reduced mainstream appeal presents sourcing restrictions. If ever need be, higher-power solar panel variants with similar electrical characteristics are more challenging to source than their lower-power counterparts.
Residential: Increased structural wind loading. Solar panels, in general, are like sails. The greater the surface area, the more wind you will catch. Even though reduced power format solar panels occupy a similar surface area, the reduced size and increased mounting points reduce the pressure at each fixing location.
Residential: Potential manhandling degradation. At the time of installation, the handling of solar panels is critical. The lighter physical nature of a reduced frame format solar panel ensures manhandling stress is lessened. If affected, these stressors will present as snail trails/microcracks and, even hotspots. Manhandling stress reduces the manufacturers warranty to 0 years.

Nil. Solar panels form part of a system and are priced on a per/watt basis. Therefore, there is often no cost difference at a wholesale level with a like-for-like increased vs reduced dimension solar panel format incorporated a system. It is a misconception that you are receiving better solar panels due to an increased power class.

Retailers will always buy solar panels wholesale at a per/watt purchase price. The cost is almost always identical, as the efficiency and technology define the solar panel, not the power output.

Interestingly, solar panel higher-power output deception is nothing new. Pre-2020, marketers would leverage the higher-power qualities of 72-cell solar panels. Even though a lot has changed since, so too have the associated components to adapt to the change. 72-cell solar panels were specifically designed for C&I installation types and high-power inverters, with 60-cell solar panels better suited to the residential market and residential-specific inverter technologies.

From 2023, with most new solar panels available in Australia ranging from 21-22% module efficiency, the ideal residential solar panel with mainstream electrical characteristics for your future flexibility currently ranges between 400 to 440 W. As REC Solar would suggest, seek “Better, not Bigger”.

Are the benefits of REC Solar panels worth the cost?

Bottom corner of an REC Alpha Pure R solar panel with an abstract green, blue and yellow graphic background.

One of the most awarded solar panel brands for innovation over the last decade, the 2023 range of REC Solar panels is, without doubt, some of the most evolved market-wide. With such heavy investment into research and development of highly developed technology, a cost premium is inevitable. However, given that many lower-priced substitutes exist, it’s always wise to consider whether the cost of REC Solar panels is worth the additional expense.

REC Solar may not be a household name. However, this wholly-owned subsidiary of Reliance Industries is more than entrenched and respected amongst solar enthusiasts due to a successful decade of producing innovative technology. Since exceeding expectations with an Intersolar Award in 2015 for the REC TwinPeak range, more and more researched investors have begun demanding REC Solar panels.

Accolades continued when REC released the REC Alpha range in 2019 (Intersolar Award 2020), facilitating the widespread adoption of superior-performance Heterojunction (HJT) cell technology. In 2022, REC enhanced the Alpha range by developing it to be entirely lead-free, an issue that plagued all competing solar panels. A revolutionary development claiming the REC Alpha Pure range the esteemed Intersolar Award 2022.

From 2023, two world-class REC Solar panels will be available, each resonating with a distinct module purchaser, with one Alpha model phased out by the end of Quarter 1. Primarily differentiated by cell technology, REC solar panels come in three formats; Heterojunction (Alpha), N-Type (N-Peak) and P-Type (Twinpeak). However, the N-Peak series is no longer available on the Australian market due to limited market appeal.

Alpha Pure R	410 W	21.2%	-0.26%	Datasheet
Alpha Pure	400 W	21.6%	-0.26%	Datasheet
Twinpeak 5	400 W	20.3%	-0.34%	Datasheet

Alpha Pure R (410 W): Lead-free 3rd generation Intersolar Award-winning (2020, 2022) Heterojunction cell technology for optimal energy generation potential. More than efficiency, Alpha Pure R’s leading temperature coefficient of -0.26%°C (lower the better) assists the most significant energy harvesting ability in temperatures above 25°C.

Alpha Pure (400 W): The 2nd generation REC Alpha solar panel that attracted worldwide recognition for the second time (Intersolar 2022), paving the way for lead-free solar and a better future.

Twinpeak 5 (400 W): Hard not to love a solar panel in its 5th Generation prime. The REC Twinpeak 5 is the Award-winning (2015) split-cell module technology now used by competing solar module manufacturers globally. We understand, nothing beats an original.

The base product warranty of all REC Solar panels is 20 years. An additional 5 years is equipped upon installation and registration by an REC Certified Solar Professional bringing the total product warranty period to 25 years. Such a program assists end-user module purchasers in knowing the installer is brand aligned with greater product knowledge for successful implementation.

It’s important to note that even though the Performance warranty of all REC Solar panels is 25 years, the annual maximum power output degradation varies slightly (0.25%) within the Performance warranty period.

In 2010 after considering 200 possible global locations, REC nominated Tuas, Singapore, as its new centralised global manufacturing hub. Renowned as one of Asia’s most evolved commercial centres, Singapore provides a strategic base to ensure ease of international distribution while emersed in a society that understands the importance of maintaining high-quality standards. Continuing to ensure the REC name is synonymous with its tagline of Solar’s most Trusted a decade later.

Award-winning technology will always cost more than the market average, positioning the Alpha range of REC solar panels within the higher calibre of capital investment requirements. As a gauge, an approximate 20% price difference exists between Twinpeak 5 and Alpha Pure R series REC Solar panels when combined as a package after the current zone 3 STC subsidy (Perth & Bunbury region).

Defining overall economic viability, leading technology is always the most desirable. However, a trusted brand’s most economical option may be more appealing for project feasibility. The good news is that REC Solar panels are superior to most competing solar panels by technical specifications, justifying an increased investment potential.

How does a Huawei inverter compare to European alternatives?

Huawei inverter and battery with city skyline in the background. Referencing: Oversizing Solar Arrays on Inverters with a battery.

A perceived newcomer to the solar inverter manufacturing (in comparison to alternative brands), Huawei, the global telecommunications mega-giant has actually been refining solar inverter designs many years prior to commercial availability. With such refinement prior to release, are Huawei solar inverters able to provide the satisfaction and meet the expectations you desire from a particular solar inverter technology?

Similar to most inverters, Huawei solar inverters should meet suitability based on each installation circumstance. Circumstances which cater towards; personal preferences, installation design characteristics, budget, solar panel preference etc. Understanding such will inevitably help you understand if the following Huawei solar inverters are the right choice for your solar project.

The anticipation surrounding Huawei’s cutting edge residential inverter technology first began in 2016 when impressive product specifications first began circulating.

More common than ever, companies will advertise solar packages with what appears to be a mismatched product pairing. A combined quantity of panels, such as a 6.6 kW solar array feeding and a 5 kW inverter should defy electrical good health. However, beyond being one of the most efficient approaches to driving a solar inverter, there is more than one advantage when oversizing solar arrays to their respective inverters.

Many leading solar inverter manufacturers, such as SMA and Fronius, suggest that if remaining within the rated voltage and current input ratings of the inverter, oversizing a solar array into an inverter by up to 50% is the best way to maximise your solar energy yield.

In light of this, even though peak power production will be clipped at the inverter’s output capacity, the overall kWh generated throughout the day will be increased through the broadening of the solar production window.

Solar inverters are more efficient when they operate at peak output power. That’s the consensus. However, the modern-day maximising of production is often based around particular grid or feed-in tariff limitations.

Western Power (in Western Australia), the network operator, limits the implementation of single-phase solar inverter capacity to no greater than than 5 kW maximum output. Three-phase solar inverter capacities greater than 5 kW are export limited via the integration of an inverter connected energy meter to no more than 1.5 kW per phase.

Similarly, solar inverter capacities that exceed 5 kW output capacity are excluded from Synergy’s Distributed Energy Buyback Scheme (feed-in tariff ) of 2.5c per unit (kWh) off-peak and 10c per unit (kWh) peak when exported to the grid.

In theory, as much as possible, ensuring the input voltage and current ratings of the solar inverter are not exceeded. Beyond such, alternative external limitations set by national (Australia) and local regulatory authorities are in place to also limit your ability to oversize solar inverters in general.

The simple calculation that applies in all instances, without a battery, to be eligible for Small Technology Certificates (STCs – also referred to as the subsidy) on a solar energy system in Australia is as follows: Solar inverter output capacity multiplied by 1.33 or 33%.

Without a battery, 1.33 or 33% greater than a solar inverters rated output has been determined by the powers that be in Australia, as an acceptable oversizing increment without being detrimental to a solar energy systems ability to offset carbon emissions.

Remember, your ability to claim a subsidy (STCs) on the upfront purchase price of a solar photovoltaic system is based on its ability to offset carbon emissions now and into the future. Disregard the 1.33 value if adding a DC-Coupled battery.

Forget the equations. You need to know the most you can oversize your particular solar inverter capacity. Below are the most common instances to oversize solar inverters and their maximum input capacity which apply to STCs (Small Technology Certificates) – your subsidy:

Inverter size	Max. Solar Array Oversizing
3 kW	3.9 kW
5 kW	6.6 kW
8 kW	10.6 kW (9.9 kW due to design limitations)
10 kW	13.3 kW
15 kW	19.9 kW

When network limitations are set by inverter output capacity, oversizing solar panels to an inverter is the best way to maximise generation capacity towards overall kWh.

Satisfy your curiosity. An astute energy investor deserves a competitive solution.

The most common system combination where the oversizing of solar panels to an inverter occurs is 6.6 kW of solar panels on a 5 kW inverter. This is because residential Synergy customers in Western Australia who install an inverter capacity greater than 5 kW will forfeit the ability to qualify for the Distributed Energy Buyback Scheme or DEBS (commonly referred to as Synergy solar feed-in tariff).

Therefore, the best way to achieve greater overall power production (yield) without increasing solar inverter capacity is to oversize a solar array to the maximum allowable input capacity of an inverter while remaining eligible for STCs. Additionally, single-phase solar supplies connected to the Western Power network are currently limited to a maximum of 5 kW output to mitigate the effects of phase imbalance.

Common systems where the solar array input oversizes the solar inverter output with no detriment to manufacturer warranty:

Even with an increased average cost per kW between a 3.9 kW and 6.6 kW solar energy system (due to the way the STC subsidy offsets a system cost), there are still scenarios where an oversized solar array of 3.9 kW combined panel output on a 3 kW inverter may take preference.

Certain network limitations can exist around 3-phase 10 kW inverter capacities, enforcing a maximum 10 kW output capacity. However, the popularity of the 10 kW inverter range by most inverter manufacturers ensures an enticing and reduced capital outlay as opposed to selecting a 12 kW or 15 kW inverter capacity while generating almost the same overall yield.

As the popularity of 13.3 kW solar arrays oversized on 10 kW inverter capacities increases, so does the level of network restrictions. To mitigate the effect of excess energy on the network, network operators (such as Western Power) stipulate the requirement for inverter connected power sensing equipment at the point of supply.

Power sensors (inverter connected energy meters), when programmed per local requirements, limit a solar energy systems grid export ability to no more than 1.5 kW per phase. A popular reduced format of the 13.3 kW system design, where alternative limitations may exist, is 10.6 kW or 9.9 kW of solar panels oversized on an 8 kW inverter.

With a DC-coupled battery is where oversizing solar arrays become interesting. Forget the 1.33 rule and broaden your horizon to inverter manufacturer-nominated input limitations as your ability to offset carbon emissions has increased as deemed by Australia’s Clean Energy Regulator. Therefore, the ability to claim STCs on additional solar array capacity becomes available.

With broadening limitations, system configurations must be assessed on an individual basis when oversizing solar arrays on inverters with a DC-coupled battery. In such a scenario, contacting Perth Solar Warehouse sales support can assist in maximising the generation potential of your energy system. However, there are some basics to consider;

The combined solar array voltage should be suitably less than the inverter input voltage rating per MPPT.
The combined solar array current should be suitably less than the inverter input current rating per MPPT.
The input power doesn't exceed manufacturer-nominated values.
The electrical characteristics of the solar array design remain in accordance with local regulations.

Understanding such limitations can increase solar generation ability and savings potential exponentially. Even though the AC output power is limited by the inverter rating, the overall kWh (power over time) value increases. The Huawei SUN2000-L1 & M1 hybrid inverters, when paired with a Huawei LUNA2000-L0 battery, provide a remarkable solution for those who demand maximum yields yet may be limited by a nominated inverter capacity for a particular reason.

Which Trina Solar panels are ideal for you?

A pioneering solar module manufacturer, the Trina solar panels available to consider in 2022/23 continue to push evolutionary boundaries through proprietary designs. However, not all Trina Solar panels will be the ideal solution for your particular solar project. The researched investor inside of you has brought you here. Therefore, delve a little deeper and discover the one particular Trina Solar panel that is proving too hard to resist as a potential short-list option for many.

We all know there is more to the idea solar panel selection than manufacturer alone.

Trina has made it clear that their primary focus will be around 210mm wafers (cell dimensions), significantly increasing over average wafer sizes. Perhaps this is where they view the future of module designs gravitating. If modern trends continue, Trina will dominate this space with such an early mass adoption ahead of the industry trend.

Understanding which Trina solar panels utilise the new 210mm wafer design it’s relatively easy. Look for the Vertex series. Don’t look too deep into the variants as it’s usually a variant of the below two, either blacker or larger in dimensions by adding more cells. In such a case, the efficiency remains relative (greater power output doesn’t always mean better panel).

Model	Power	Efficiency	Temp COEF (°C)	Download
Vertex S+	415 W	21.4%	-0.30%	Datasheet
Vertex S	415 W	20.8%	-0.34%	Datasheet
Honey	370 W	20.2%	-0.35%	Datasheet

Trina Vertex S+ (415W): There is something genuinely exciting about the Vetex S+. Possessing a high-performance n-type monocrystalline multi-busbar cell formation, the new-generation design is further enhanced with a world-first 1.6mm dual glass encapsulation retaining a total glass thickness of 3.2mm. Such a result creates a super stable photon harvesting environment with fewer degradation points when compared to conventional glass-laminate solar panels.

Mitigating the previous weight drawback associated with dual-glass encapsulation, the strength of conventional 3.2mm protective glass remains. The Trina Vertex S+ is a 2022 testament to engineering genius.

Trina Vertex S (415W): Consider the Vertex S an almost replica of the Vertex S+ without the new-generation n-type monocrystalline cell formation or dual glass encapsulation. The most notable differences include a p-type monocrystalline cell structure in the new 210mm wafer format and a conventional glass-laminate encapsulation. 415 Watts, similar to the Vertex S+, provides the ideal multiplier for maximum solar array oversizing to inverter output ratio as per the 1.33 rule in Australia. The scaled-down technology within manages to provide a little capital investment respite.

Trina Honey M (370W): The final remaining Trina solar panel design of the previous era, Trina Honey M modules have provided a reliable and economically viable solution to thousands of installations across Australia. Used in thousands of installations across Australia, the half-cell module design now languishes behind Trina’s proprietary Vertex design with a 210mm wafer for a not too dissimilar price. 370W is the ideal multiplier for maximum solar array oversizing for a solar energy system without a battery in Australia.
