Solar panel costs vary widely depending on system size, roof type, and the specification you choose — which is exactly why every quote you see online is really just a starting estimate. Here’s what actually drives the price, and how to get a number that’s specific to your home.
What Actually Drives the Cost of a Solar Panel System
The final price of a solar installation depends on several factors working together: the size of the system (measured in kWp), the number and type of panels, the inverter specification, roof access and scaffolding requirements, and whether you’re adding extras like battery storage or an EV charger at the same time. Two homes with similar-looking roofs can end up with very different quotes once these details are factored in.
Why We Don't Publish a Flat Price Online
You’ll see plenty of “average cost” figures floating around online, but publishing a single number wouldn’t be honest — it would either be too low to be useful or padded to cover worst-case scenarios. Instead, we survey your specific roof, shading, electrical setup and energy usage before giving you a fixed quote, so the number you receive is the number you pay.

What's Included in a Personalised Quote
A proper quote from Green System Solutions covers the full installation — panels, inverter, mounting, wiring, scaffolding, MCS certification paperwork, and a clear breakdown of what you’re paying for at each stage. There are no vague “from” prices or hidden add-ons revealed after you’ve committed.
Financing Options to Reduce the Upfront Cost
If paying the full cost upfront isn’t the right fit, we can talk you through the financing routes available so you can weigh up the numbers properly before deciding. See our Pricing & Finance page for more detail on how this typically works.
