Ranked as one of the best solar companies in Perth by review

Perth Solar Warehouse team members ranked as one of the best solar companies in Perth by customer reviews on Google and Solar Quotes

With enough time, the best solar companies Perth has to offer begin to surface. Over a decade of mainstream popularity and with the internet as a popular research tool, customer satisfaction levels have become apparent with long-standing companies. Companies that have yet to stand the test of time still have untarnished review profiles, or often noticed is the resetting of Google listings to wash away past negativity. Although, the pool depth is evident and easy to determine for any discerning investor.

Every day, a solar company proclaims to be number one, but by what measurement? If it’s volume, that provides little insight into how a company treats their customers (long-term), especially if the capacity achieved is from completing a few very large jobs in a nominated period. Some will hold onto the highest volume credential in a time that is no longer relevant (consumer expectations have changed in 2024). However, the gauge most customers seek is how the considered best solar companies in Perth evolve while attending to their customers over time, combined with voluminous success as bankability towards an energy investment decision.

Advantageously, customer satisfaction measured over time is publically available and current.

Gauging customer satisfaction

Two reviewing platforms provide a level of commonality amongst all of the best solar companies in Perth. Google and SolarQuotes.com.au. Alternative platforms exist, such as ProductReview and TrustPilot, but these are marketing machines that reap the rewards when organisations subscribe for benefits and the ability to weed out negativity. Speculation also surrounds legitimacy. Appealing for some but not the most transparent gauge for consumers.

Google is open slather for everyone. It’s an excellent tool to ensure companies are on high alert, even those that have yet to purchase from them. Always be wary of low review counts, no mixed opinions, and reduced review text (frequent reviews of 10 words or less) – when you genuinely love a service, don’t you want to tell the world?

Tip. Spot dubious reviews when comparing:

  1. Pay attention to the names of reviewers (there may be patterns).
  2. The number of reviews reviewers have made.
  3. The average review content/length (is it an obligation or genuine experience).
  4. Assess the lowest reviews to see how a company responds to dissatisfaction.
  5. A small amount of dissatisfaction is a good thing. It provides a measuring stick of the business and performance under pressure.

SolarQuotes.com.au is contentious because paid elements exist for installers. Therefore, solar companies that purchase leads from solarquotes.com.au naturally have more reviews than those that don’t, as the platform always follows up the experience should a lead-purchasing solar company win your work. Unlike alternatives, SolarQuotes.com.au reviews are good for purchasers identifying different elements of installer competency. Those among the best solar companies in Perth have customer reviews here – even the non-subscribers.

 SolarChoice.com.au is similar to the SolarQuotes.com.au website. The installer review section is new, so the review pool is low. Although, their online content is detailed and free for the energy investor doing their research. Due to more likely legitimacy and transparency, solar companies have their reviews listed and prioritised by Google search results.

Facebook’s business reviewing mechanism is as credible as Facebook Marketplace before 2023. It had been rarely supported, and reviews could be purchased from vendors that many exploited. Perth Solar Warehouse Facebook recommendations are genuine but urge customers to exercise caution when comparing companies here.

Criterea that can be measured

1) Time is an outstanding measurement. Given that most warranties are 10 years or longer, you need a company that’s been around 10 years or longer with historical online customer experiences. Your system is only as good as its installation company, simple. The longer, the better.

2) Diverse satisfaction, because the internet is so much bigger than one review platform. Often companies will focus on one review website for the purchaser with rose tinted glasses. Comparative reviews on alternative media channels suggest differently and provide greater insight into who are genuinely the best solar companies in Perth WA.

3) Pool depth of aligned platforms. Ignore our choice of reviewing websites. Find multiple platforms that your shortlist of best solar companies has in common. Any two or three, but make sure they are equally comparative (alternative websites don’t qualify). Consistency is what you want to see. Hone in on inconsistency.

4) Locally based, as dealing with the eastern states (or foreign support agencies) could be more fun. Homegrown organisations are the best solar companies in Perth hands down. Local business gets you. We understand local needs and can better assist at times of support. The world is on a sustainable energy journey from 2024. You need local knowledge and experience on your side.

5) In-house installation (not sub-contract) gives customers the system execution assurance they desire. In-house installers are more likely to receive regular product care and safety training. Provided time-based remuneration to perform the job correctly and offer no installer to company warranty disputes.

6) Goldilocks company Not too big, where customers are simply another cosmic element. Not too small, where business stability (warranty certainty) varies. We’re just right as your future energy partner.

Customer experience

Some solar companies have reviews. Others have experiences from customers who are embarking on a future energy journey. This section was just for writing that. Okay, that and the cumulative number of reviews/experiences. 

Depth over time is important in this scenario. The volume of high-level experiences sustained over time is a key metric for an informed buying decision. Over 1000 experiences on comparative platforms, the genuine ones. Perth Solar Warehouse customer experiences spanning the last decade:

Tip: Compare the best solar companies on low review count platforms (less than 50). Low review count platforms ensure a company isn’t drowning out the negativity on key targeted platforms with reviews that lack substance. A high volume of 3 to 5 word reviews isn’t an experience. It’s an obligation.

Manufacturer satisfaction

Manufacturers rely on dependable solar companies to implement their products, irrelevant of an individual’s accreditations. CEC Accredited installers bounce around from company to company, often with little concern or regard for previous projects. Warranty concerns arise with complexities. Manfacturer-certified partners are the best solar companies Perth customers should seek out. These solar companies will most likely be more knowledgeable about a manufacturer’s recommended installation practices through updated product training.

Leading manufacturer endorsements:

Hassle-free. Because going solar should be easy. PSW has a no-hard-sell guarantee. 

Awards & recognition

Let’s be honest. Certain awards are debatable. Others are a bit token (there’s an award for everything in 2024). Credibility helps, but it seldom makes or breaks a company for consideration. The substance and continuity from recognised industry piers is essential here.

Notable recent awards and recognitions that contribute towards Perth Solar Warehouse being recognised as one of the best solar companies in Perth:

Sigenergy’s SigenStor is a game-changer for Australia

Sigenergy SIGENSTOR render with with five in one key features listed: Solar Inverter, EV DC Charger, Battery PCS, Battery Pack, EMS

Now and again, a product comes to Australia, captivating the attention of solar energy enthusiasts. With world-renowned leading brands that already exist who are consistently innovating to stay ahead, something must be unique for something new to stand out and earn market share. In 2024, Sigenergy’s SigenStor will disrupt established brands in energy self-sufficiency with one of the most innovative all-in-one solutions, empowering users towards superior energy independence. Here’s why.


Key points

Built on a software-first foundation, Sigenergy is a manufacturer set to outpace most in the new generation of self-sufficient energy supplies. Developing new energy hardware this decade from the ground up enables innovators to think outside the box regarding a preconceived evolutionary process. With modern user experience now in the palm of one’s hand, what if an energy product for the mainstream was developed from a software-first perspective? Such a design would remove specific hardware limitations, ensuring it adapts perfectly to modern user experiences and expectations as they evolve. 

Even though existing energy technologies possess excellent monitoring and control software, limitations restrict the release of software/firmware updates required in a consistently evolving landscape. Most manufacturers have one universal web application for their products, old and new. New updates must consider all hardware models, ensuring a stable user experience. The more expansive a product range, the more diligent a software/firmware release must be, and this takes time.

Which to consider?

Even though installation professionals will have to adapt to a new way, the beauty of Sigenergy’s product offering is in its simplicity, and your only consideration of which foundations to consider initially depends on your power supply: single or three-phase. Rumour surrounds a potential inverter-only solution (as in other markets) to remove specific market barriers around a basic package’s initial cost. Therefore, the foundation of the Sigenergy energy product range is the controller/inverter, and the broader energy ecosystem products follow that. Greater consideration begins within the broader expansion options/ecosystem.

The Sigenergy expanded ecosystem

From 2024, home and commercial self-generated power supplies will form part of a user-empowered energy ecosystem. The more efficiently you control and harness internally generated electron flow, the more you save purchasing from the grid. Today, the choice is a disconnected analogue-style solar energy system or an all-encompassing, digitally connected energy ecosystem. Sigenergy changes this.

Two mobile phones displaying the Sigenergy App interface

The mySigen App is where the Sigenergy energy ecosystem comes together for communicative harmony. Purchase add-on hardware such as DC Bidirectional EV charging and versatile 5 and 8 kWh storage modules. Considering such versatility, it’s rare that two SigenStor neighbours are ever the same. You use your power differently from your neighbour and deserve a custom solution. Previously, more bespoke solutions were expensive to achieve, adding significant cost barriers for the mainstream. SigenStor is a testament to commercially viable custom design with the ideal modular add-on features to suit the end-user (you).

Sigenergy warranty

Ten years for major components such as the battery and controller/inverter. Perhaps what could also be considered a major component is the Gateway. However, the Sigenergy Gateway only includes two years of guaranteed cover. Understandable, considering the potential variance between unique installations’ use and power supply conditions. Installations prone to less stable power supplies are more likely to induce additional wear on the gateway relays and electronics. Reviewing similar hardware, two years on control devices such as the Sigenergy Gateway is comparative.

It’s important to remember specific exclusions apply, such as failure to comply with Sigenergy’s operating instructions and installation guide. The simplest solution to ensure a Sigenergy product warranty is dependable for the enduring period, including installation workmanship, is to purchase through Perth Solar Warehouse, a founding/proven Sigenergy partner in Western Australia.

Where are they made

Operating in more than 30 countries and with seven global offices/support centres, including Sydney, Australia, Sigenergy SigenStor products are manufactured in the heart of modern automated process: Shanghai, China. Set on a 20,000-square-meter facility, energy investors can rest assured of the tightest quality control processes before delivery. Featuring R&D, lab testing, and assembly, Sigenergy has invested in superior outcomes without outsourcing critical componentry.

What do they cost

It is a unique product to compare on cost due to its all-in-one modular design and the fact that there is yet to be competition to compete directly. More likely than not, new mainstream competition will emerge from Sigenergy’s revolutionary design towards energy independence.

We’ve left out solar panels for relative battery comparison costs. However, it’s important to remember that the cost of p/kWh includes the Sigen Energy Gateway, slightly inflating comparative DC-coupled battery figures. What is apparent is that increasing the combined energy density reduces the cost per kWh due to the one-off investment in critical components of the controller, gateway and preliminary installation.

Ultimate guide: Solar rebate Perth and Bunbury WA region 2024

Sunrise over Perth City for Solar Rebate Perth WA

Exercise caution surrounding subsidy hype. Even though the zone 3 solar rebate Perth and Bunbury region customers can access isn’t a fixed rebate/subsidy, it’s always advisable to consider your options. Comprised of Small Technology Certificates (STCs), the value is subject to potential change daily. However, more recently, the spot price per certificate has remained relatively stable, affecting a steady total subsidy amount. Here is the need-to-know information (including amounts) when considering the solar rebate in 2024.


How much are you entitled to

The solar rebate Perth customers can access varies depending on system size (combined solar module generation capacity). Most typical residential subsidies start from $1,456 for a 3.9 kW solar system to $2426 for a 6.6 kW solar energy system. Subsidies increase for larger solar energy systems based on the ability to offset more significant carbon emissions. 10.5 kW solar systems enjoy a $3882 contribution to offset the cost, while a 13.2 kW system benefits from up to $4852.

Array size
3.9 kW
6.6 kW
10.5 kW
13.2 kW

As a traded component for offsetting carbon emissions, the solar rebate has the potential to fluctuate daily while degrading in annual blocks for the remaining 7 years of the preset target.

Even though spot value fluctuations have occurred in the past, it’s advisable to avoid rushing a buying decision based on subsidy value. Instead, ensure an informed buying decision as the fluctuations, and annual variances are minimal over a solar energy system’s life expectancy.

In the following content, understand how to calculate your precise solar subsidy and the amount you are entitled to depending on your ideal energy system size.

Is there a battery rebate in WA?

Somewhat but not entirely, so we created its very own post that we keep updated individually as the landscape changes. Solar battery rebates and offers ›

Discover the savings. Your copy of the latest catalogue.

How the solar rebate works

Your new solar energy system is eligible for a nominated amount of certificates based on its ability to offset carbon emissions over the next 7 years. That’s right, you will produce clean, green energy, not just energy savings. Therefore, the Australian Government Clean Energy Regulator rewards you with a designated number of Small Technology Certificates (STCs) depending on your solar energy system size.

Your subsidy value is acquired by trading your Small Technology Certificates with big polluters who must purchase these clean energy certificates (STCs) to offset their carbon emissions towards net zero. Such complexities are often too much for most, including solar companies. Therefore, releasing the Small Technology Certificates for a point-of-sale discount at an agreed market rate is more manageable.

At the time of writing, $38 is considered a stable rate amongst most retailers, allowing for potential market fluctuations without consumer clawback in the event of change.

On top of a point-of-sale discount (subsidy), most residential solar systems are eligible for a feed-in tariff through Synergy for excess energy exported to the grid. Learn more ›

Lock it in

Small Technology Certificate trading values have the potential to vary. July 2017, the spot value of STCs plummeted from $38 to $26 almost overnight due to an oversupply with insufficient purchasers. One year of STC value uncertainty followed. Since this and other instances, lost STC value recovery (clawback clause) is embedded into the terms and conditions of many installation contracts. In addition to the contract price, such could render the lost STC value payable by the customer after installation.

Perth Solar Warehouse monitors markets extensively and will never alter costs after a contract is signed unless agreed upon by all parties.

An adequate installation agreement should have the following clearly defined:

  • STC value, e.g. $38.
  • STC quantity, e.g. 64 certificates (as in 6.6 kW).
  • STC total value, e.g. $2426 ($38 x 64 certificates).

When offered a point-of-sale discount as part of a solar package, you want the solar rebate to be precise and broken down into an easily calculable format. 

Hassle-free solar. From a locally based company you can trust. Google & SolarQuotes 4.9/5

How to calculate it

A formula for calculating the solar rebate exists, and here it is.

Array Combined Watts (Standard Test Conditions) x 1.382 x the current Small Technology Certificate multiplier of 7 years / 1000. The result is the maximum number of Small Technology Certificates eligible for your solar energy system.

Example: 6.6 kW Solar System

Solar Array Combined Watts (6600) x 1.382 x 7 (years) / 1000. The resulting number is the maximum STCs eligible.

(6660 x 1.382) x 7 / 1000 = 64.

Determining the amount of Small Technology Certificates (STCs) is 64 for a 6.6 kW system. Multiply this amount by the current market value of $38.

64 STCs x $38 = $2426.

Subsidy by system size expanded

For most, calculations are too time-consuming in a modern world full of fast information. It would be best if you had the figures to verify against.

The most common solar rebate Perth residential homeowners can expect to receive based on a $38 STC value and using a 440 W solar panel variant for multiplication is as follows:

Array size
3.9 kW
6.6 kW
10.5 kW
13.2 kW
19.8 kW
26.4 kW
39.6 kW

The above combined Small Technology Certificate value is an example and subject to potential market fluctuations.

In all system sizes, the solar rebate Perth and Bunbury region customers can access provides a significant upfront saving on the cost of energy security. Considering the value of the subsidy is due to reduce each year, now is an ideal time to invest in your energy future. Aim for a hassle-free transition to solar power. Perth Solar Warehouse Sales Support ensures you get the maximum solar subsidy with no risk potential.
