Commercial solar panels made for WA sunshine

Perth is one of the world’s sunniest cities, which makes WA a prime location for any business looking for solar energy solutions.

All this sunshine can mean harsh conditions for solar panels, so you need to make sure you choose good quality solar panels that can withstand WA conditions.

Things to think about when choosing the best solar panels for your home

Choose a brand that is a tier 1 company that offers a good, long warranty.

This means that they are financially strong, invest heavily in research and are more likely to be around, long after your '20+ years performance warranty' expires.

Choose quality solar panels: When you’re looking for solar panels for your business, our Commercial SolarReturn team supplies solar panels from the world’s leading manufacturers.

Between 10am and 2pm is the best time for solar energy production on sunny days.
The energy produced by solar panels is directly related to the amount of energy they receive from the sun – so dust, dirt and bird droppings are the natural enemy of your commercial solar panels!


Hot weather means more your solar panels will produce more solar energy for your business.
The amount of electricity your solar panels generate actually decreases in hot weather. Solar panels operate best on sunny days at temperatures of up to 25°C.

Check your solar panel performance 

Top performance is important in every area of your business – and it’s easier to track the performance of your commercial solar panels than you might think. Most solar systems have an app you can download to measure their performance over time.

Does the slope of our roof have an impact on solar panel positions?
Our Commercial SolarReturn team recommends that solar panels have a tilt of at least 10° so the rain can take care of keeping them clean. If your roof slope is not ideal, installers may be able to design an appropriate mounting frame to get a better orientation and elevation for your solar panels.
How many solar panels should our organisation have?
It’s not simply a case of the more solar panels, the better for your business. It’s important to get the solar system that matches your needs and the amount of electricity your business uses, as this will be more beneficial for your business than exporting excess energy to the grid. Our Commercial SolarReturn team will look at exactly the way you use electricity and recommend a solution based on  your business needs.
How much energy will solar panels generate for my business?
The more sunlight that falls on your solar panels, the more solar energy will be produced! The amount of energy your commercial solar panels will be able to generate will depend on a number of factors, including the number of panels and inverter capacity of your system.
What’s the best position for solar panels to be installed?
North-facing roof space is perfect for solar panels in WA, as this means the panels will catch the most light. West-facing rooftops can also work well to catch the hot afternoon sun. 

Even a small amount of shade, from things like trees, roof ventilators or antennas will reduce the amount of energy your panels produce. Shading or dirt on just one of the cells in a solar panel can cause loss of power from a number of cells, not just the one that is shaded.
