One Power Solar & Electrical is a Top Volume Battery Retailer, and Best Rated Retailer for 2025

The installation of thousands of solar batteries within a single year stands as a remarkable achievement for any solar company. Such a feat not only underscores a significant level of success but also underscores the company’s credibility, deserving recognition.

Since 2009, SunWiz has diligently monitored every solar power system installed across Australia, meticulously documenting the involvement of each solar company in these installations. As the indisputable authority on solar market volumes, our data is extensively referenced by corporations, non-governmental organizations, and governmental bodies alike. We’re also Australia’s expert on the solar battery market.

After thorough analysis of the solar installations and solar battery installations that occurred in 2024, as well as assessment of customer reviews of every solar company, SunWiz has found the following to be true:

  • One Power Solar & Electrical is in the Top 10 Companies Australia-wide for residential capacity of solar battery systems installed in 2024.
  • One Power Solar & Electrical is in the Top 10 Companies Australia-wide for being Best Rated in the Most Popular category based on 303 customer reviews averaging 4.90 stars.
Rating so highly with their customer satisfaction at having had installed so many batteries is an extraordinary result! 

About One Power Solar & Electrical

Here are some of the reasons why Aussies choose One Power Solar & Electrical

Custom built for your property

If you choose to buy a solar power system from One Power, one of our solar experts will assist in creating a personalised proposal based on your specific energy needs, local solar incentives, property location, and various other factors. The outcome? A system built to save you money.

“One-stop shop” for all things solar

Most solar companies use third party contractors to install new solar systems. One Power Solar is different, we employ dedicated, in-house solar installers and offer customers direct access to a wide range of solar products.

Cost-effective, affordable solar

Investing in a new solar system or optional solar battery is simpler than you may expect thanks to a specialised range of solar incentives and financing options on offer.
SunWiz researched the reviews of every Australian solar company, because we discovered consumers may be misled by overlooking the context of solar installer reviews. 
 
Our research revealed 50% of solar businesses have a 5-star Google review rating. 
 
“50% of solar businesses have a 5-star Google review rating”
 
That makes it impossible to sort the good from the great. Looking for a great solar company shouldn’t be like looking for a needle in a haystack.
 
Even more concerning, and potentially resulting in customers making poor choices was this finding: 4.2 star google review rating puts you in the bottom 17% of all installers.
 
“A 4.2-star google reviews rating may be decent for a restaurant, but it’s it makes you one of the worst solar companies in Australia”
That’s why SunWiz created the Best Rated Solar Retailer awards: to help customers make good decisions by identifying the best of the best. 
  • We compile information from more than three commonly used review sites, and eliminate bias by only including retailers with strong results across multiple platforms, which we then perform a weighted average upon. 
  • We exclude retailers with less than 100 reviews, to help customers truly identify the most popular companies.
  • We observe that it’s extraordinarily difficult to maintain a perfect 5-star rating as you get bigger. So we only include retailers with >100 reviews and >4.8 star rating. That puts these businesses in the top 100  best-rated solar businesses in the country. 

Being recognized as one of the top-rated solar retailers by customers is a significant accomplishment that showcases the retailer’s commitment to delivering exceptional customer service and quality products. Achieving high ratings from customers is no easy feat, as it requires consistent dedication to meeting and exceeding customer expectations. Customers are likely to rate a solar retailer highly if they have received reliable and efficient service, timely installation, and a competitive pricing structure.
