Customer Insight

Happy Customer Ross Underwood after purchsing a 13kW Solar Deal by Perth Solar Warehouse

Nothing short of brilliant. Quoted a very reasonable price for a 6.6Kw system and the guys were efficient and informative when they installed it. PSW did all the liasing with synergy to make sure our connection ran smoothly, I didn't have to do much of anything. They also communicated with me very well, so impressed. We are building a new house now and I will certainly look to them to install solar there.

Happy Customer Neil Tilbury after purchasing a 13kW Solar Deal by Perth Solar Warehouse

We had a 6.6kw system installed in December 2022. It has generated over 40kw every day, except on partly cloudy days, when it generated around 37kw. We are extremely happy with our solar power system choice. PSW were very transparent and extremely helpful and patient with us while we were deciding on the best option for our needs. They gave us a range of systems to choose from. The installation was done very carefully and professionally. I would highly recommend them for solar power systems.

Happy customer Ishaan Sinha Review on 13kW Solar Deal

After extensive research, we decided to go with PSW. Their pricing is competitive and represents great value for money. The entire process was seamless, transparent and professional. From the initial quote, countless questions which they were more than happy to answer all the way through to installation.

Their in-house installers Joel and Dan were efficient and friendly and did a great job cleaning up after the installation. Highly recommended!

Frequently Asked Questions; 30 kW Solar

Western Power may restrict inverter capacity in certain network locations to no more than 30 kW output capacity. As solar panels rarely reach peak rated power, certain solar inverter manufacturers state that their inverters can be overloaded by up to 50%. Although, the Clean Energy Regulator has had their say on this topic and capped oversizing to 33%. Therefore, 30 kW inverter capacity x 1.33 = 39.9 kW of solar panels. Internal post: Oversizing Solar Arrays on Inverters Increases Savings Potential ›
This depends on you. A 39 kW solar energy system with a 30 kW inverter will generate an annual average 175 units (kWh) per day. However, each commercial premises consumption profile is unique, as unique as your finger print. Sales support can provide detailed bill reduction estimates based on your past energy usage patterns. By using advanced software, the more past power bills you provide the more accurate your bill reduction estimate is likely to be.
Yes. However, as with all 30 kW solar systems, battery choices are limited. For example, if the only battery you want to install in the future is a Tesla Powerwall 2 (AC coupled), then selecting any standard inverter will work. Although, should your preference be a BYD or Sungrow SBR (DC coupled), a compatible solution would require a specific hybrid solar and battery inverter.
Eligible Perth and Bunbury region customers within STC Zone 3 receive up to a $16,763 point of sale discount (subsidy) when installing 39 kW of solar panels on a 30 kW inverter. Based on 441 claimable Small Technology Certificates, a system incorporating 84 x 475 W solar panels and a $38 STC market value. 441 STC’s x $38 value = $16,763 subsidy. For your convenience, the Perth Solar Warehouse 30 kW solar package prices include the subsidy already deducted as a point of sale discount (redeemable by Perth Solar Warehouse after installation).
Systems greater than 5 kW inverter capacity are exempt from the Synergy Distributed Energy Buyback Scheme (DEBS).
