The price of a solar system is set by the number of panels, the watt-peak capacity per panel and the type of inverter. A system with micro-inverters costs more to buy than a central inverter, but delivers more over its lifetime on a roof with shade or several surfaces.
The short answer
Do not count in euros per panel but in euros per kilowatt-hour generated over twenty-five years. That shows what a cheaper quote really costs. During the survey we calculate the expected annual yield for your roof and set it against the investment, including the 6 to 12 percent return.
What it depends on
We supply first-class products and materials only. That is not the cheapest choice on the day of purchase, but it is the cheapest over the lifetime. A system that lasts twenty years and delivers the promised yield throughout is ultimately better value than one that starts faltering after eight.

Our advice
Start with a conversation and a survey, not with a price from a table. Every home is different, and it is exactly that difference which determines what a solution delivers for you. More about solar panels can be found on the corresponding page.
