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.

  • 4.9/5 Google: +700 reviews – Perth Top 5
  • 4.9/5 SolarQuotes: +600 reviews – Legendary-rated [2023, 24], Top 2 [2024
  • Sunwiz: Best Rated Installer, Top 5 combined volume WA [2023,24]
  • EuPD Research: Top Brand PV Installer [2023,24
  • Tesla: Premium Certified Installer [2022,23,24] – Top 2%
  • Tesla: Performance Excellence Award 2024 – Top 10% volume (AU)
  • Online customer review timeline: +10 years

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. For added depth of research combine this with open-source [PSW Energy] installation volumes as bankability towards an energy investment decision.

Advantageously, customer satisfaction and installation volume over time are publically available and current on trusted platforms.

Gauging customer satisfaction

Two reviewing platforms—Google and SolarQuotes.com.au — provide a level of commonality among all of the best solar companies in Perth. 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 pre-screen negative sentiment through ‘review gating‘. Speculation also surrounds legitimacy of reviewers. 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 and no mixed opinions.

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 as this is a popular customer research tool for most.

 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. Ask yourself, are you buying a dream or a proven energy supply? Choose a company whose guarantee compliments its operational history for greater warranty assurance.

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 hands down the best solar companies in Perth. 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 gives customers the system execution assurance they desire. In-house installers are more likely to receive regular product care and safety training. Provided the ideal time to perform the job correctly providing no complications towards installer to company warranty disputes.

5) Visual competency away from stock images (there’s a difference). A company proud of its workmanship will display it with in a deserved real-world, native environment showcasing. Many companies won’t. The choice is yours: enhanced aesthetic appeal or the unknown.

6) Goldilocks company (for fun) 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. A solar company invested in your outcome is both personable and approachable, with genuine history and evolution (real people included).

Customer experience

Some solar companies have reviews. Others have experiences from customers who are embarking on a future energy journey. 

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 (platforms with less than 50 reviews). 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. SAA-accredited installers bounce around from business to business, 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.

Perth Solar Warehouse’s 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:

Silicon wafer prices rise, wholesale module prices likely to follow

Advanced stage of silicon wafers within the solar module manufacturing process, under a red light with an engineer observing through a processing window to identify that silicon wafer prices have stabilised and and downstream effect to overall module costs is coming.

The wholesale downward trend of solar module prices on a cost-per-watt level had to end eventually, and the tide may have just turned, citing an August increase in silicon wafer prices by LONGi and TCL Zhonghuan—two large manufacturers of silicon wafers used in solar panels. This comes as an overdue respite for solar module manufacturers seeking a return to profitability in 2025. So, what does this mean for the future solar energy landscape locally?

Key points

Like all global markets, the solar energy market has endured an interesting period, with continued ripples affecting purchasing certainty at scale: COVID-19, the Russia-Ukraine conflict, US Manufacturing laws, and the overall complex international landscape, which affect supply chains in a start-stop, start-stop, start-again motion.

The recent increase in silicon wafer prices is a reprieve for manufacturers forced to sell excess stock below the cost of manufacture. Demand for silicon wafers is a sign that the previous market saturation has cleared, and pressure for increased production of the fundamental component used to build solar panels has returned internationally among a broader segment of solar panel manufacturers. Interestingly, a turn towards higher solar module prices is good for purchasers.

Why are increased silicon wafer prices good?

Considering the new solar panel warranty is at least 25 years for residential rooftop solar panels, system owners need a manufacturer that is more likely to be around in 25 years. When writing, most solar panels at wholesale in Australia are close to or below the manufacturer’s production cost. All businesses have a limited window to exist without margin. An increase in silicon wafer prices signals that many remaining manufacturers have more likely weathered the loss and resumed taking new orders.

Forecast: Leading manufacturers will return to profitability in 2025/26 as demand firms through more countries adopt a more carbon-neutral future. Smaller module manufacturers will experience an enduring period of uncertainty.

What should purchasers consider?

1. The Small Technology Certificate (STC) value used to subsidise solar energy system costs in Australia will be reduced from the 1st of January 2025. Example: A $38 Small Technology Certificate value and 440W solar panel for multiplication of the most common system sizes in the Perth and Bunbury region of Western Australia:

3.9 kW

  • 3.9 kW = $1,456 – 2024 installation
  • 3.9 kW = $1,248 – 2025 installation

6.6 kW

  • 6.6 kW = $2,426 – 2024 installation
  • 6.6kW = $2,088 – 2025 installation

10.5 kW

  • 10.5 kW = $3,882 – 2024 installation
  • 10.5 kW = $3,327 – 2025 installation 

13.2 kW

  • 13.2 kW = $4,852 – 2024 installation
  • 13.2 kW = $ 4,159 – 2025 installation

19.8 kW

  • 19.8 kW = $7,279 – 2024 installation
  • 19.8 kW = $6,239 – 2025 installation

39.6 kW

  • 39.6 kW = $14,577 – 2024 installation
  • 39.6 kW = $12,478 – 2025 installation

99.8 kW

  • 99.8 kW = $36,717 – 2024 installation 
  • 99.8 kW = $30,908 – 2025 installation

2. Should silicon wafer prices continue to increase, downstream newly produced module costs will increase. Silicon wafers are a fundamental component of the greater global demand for improved sustainable energy resources in areas with abundant sunlight than alternative sustainable energy sources.

Weight to the argument

As the August 2024 PV Magazine article Chinese PV Industry Brief: Longi, TCL Zhonghuan Raise Silicon Wafer Prices points out, major silicon wafer manufacturers Longi and TCL Zhonghuan have recently increased their prices. This is due to several factors, including rising polysilicon prices and strong demand for solar panels. Price increases are expected to continue, which could lead to higher solar panel costs depending on alternative local market factors.

Man with safety glasses holding two silicon rocks in front of his face. Raw material prices have rebounded alongside silicon wafer prices - an intermediate element.

Image: Raw material Poly Silicon rock used in solar panel construction.

Like any market saturation, prices fall as the demand to move excess stock becomes more critical. Astute investors identify opportunities where rebound potential exists. With record-low wholesale cost p/Watt module prices and improved global demand for the fundamental component required for manufacturing solar panels, it may well be that a more opportunistic moment for a solar energy investment exists today.
