Solar panels

Your roof goes from a cost to earning its keep. Part of the energy subscription, together with a heat pump and a battery.

Your roof turns daylight into electricity you use right away

The panels catch daylight and turn it into electricity the house uses at once. What you produce yourself, you don't buy, and it shows up most on the bill in the lighter months. Anything left over we sell on, so a sunny day works for you even when you're at work.

Your own power while the sun's up, and paid for the surplus

In the lighter months the roof can cover a big share of what you use in the day. What you don't use we sell on, and you notice it most on the summer bill. How much your roof gives depends on orientation, pitch and shade, and we work that out when we look at the whole.

In December the roof does almost nothing. It's not broken, it's December.

This far north, solar gives little when the days are short, and we'll say that plainly. The roof isn't there to save December, it's there to pay off across the year, while the heat pump and battery carry the dark months. On its own it wouldn't add up. As part of the package, it does.
