How much energy do Solar Systems in Perth produce?

As a rule of thumb, a solar PV system in Perth will generate roughly 5.3 kilowatt-hours (kWh) of energy per kilowatt of capacity per day on average throughout the year (with more int he summer months and less in the winter).

This means that a 10kW solar system will generate about 53kWh of energy per day, while a 100kW solar system will generate about 530kWh per day. Actual energy yields will vary depending on location, orientation & tilt angle and components used.

What you need to get right in a Commercial Solar Project

Commercial solar projects follow more rigorous procurement processes and it is important to ensure you have a robust approach that will lead to a great solar investment.

Independent financial model to confirm feasibility and ROI

While the environmental benefits of solar projects are clear, most commercial solar projects come down to an evaluation of the financial attractiveness of the project. The financial model for these projects should be developed by experienced photovoltaic engineers who are not trying to sell you a particular solution. Solar Choice offers a free service where any business can receive a customised Solar business case developed agnostically to products, brands and financing arrangements.

Get a range of quotes from qualified, reputable solar installers

The best way to ensure you getting a competitive and innovation solution for your project is to engage a number of high quality solar installers with relevant experience. We often hear about projects going wrong where installers are selected on the wrong criteria and insufficient due diligence has been completed on the winning contractor. Solar Choice has developed a pre-vetted network around Australia since 2008 including all major, reputable commercial installers – talk to us about running a tender for your project.

Understanding the federal rebates

Commercial solar prices are at all-time lows in Australia, partially due to the federal government solar subsidies available through Australia’s Renewable Energy Target (RET). For solar systems up to 100kW of Solar PV, the RET provides an up-front incentive in the form of Small-scale Technology Certificates (STCs). For systems larger than 100kW, the RET provides an ongoing incentive (until 2030) in the form of Large-scale Technology Certificates (LGCs).
