Solar Panels Price Guide

With so much information online about solar panels these days, it can be difficult to know what a realistic price for a solar panel system is. There are different size systems and which one you choose will depend on your roof size.
We’ve put together a solar panel price guide so you can get a rough idea of how much you’ll need to spend on a solar panel system.

General advice

Do your research

Make sure you know roughly how big your roof is and research the size solar panel system you can fit on it. Prices vary depending on the size and also the brand and quality of solar panels, so these are all things to consider.

Set a budget

After you’ve done some research, set a reasonable budget that you know you can stick to. Compare quotes with your budget so you know how much you can afford to spend.


The cost of a solar panel system depends on its size. You might also expect to pay more for a well-known or high-quality brand of panels, as they should generate you an optimum amount of electricity.
It’s a great idea to get a range of quotes for solar panels to ensure that you are getting a fair price. Beware of extremely high quotes, but also be wary of low quotes that seem almost too good to be true.
