Solar Planner

Solar payback, honestly.

Plug in your bill and roof; we'll show realistic UK generation, what you'll actually use vs export to the grid, and how long until the system has paid for itself.

What makes the payback work

LOFT BEDROOMINVERTERBREAK EVEN3,200 kWh

A roof, a sun, a meter. Before anything is installed, the only thing the system can do is read the daylight reaching that pitch.

How much you can generate

Roof orientation, pitch and shading set the annual yield more than panel brand. A clear south-facing roof outperforms a shaded south-facing roof every time.

How much of it you actually use

Daytime consumption that lines up with daytime generation pays back fastest. A heat pump, an EV or a battery turns spilled exports into useful electricity at home.

How long until the maths flips

Add the export tariff, subtract the install cost, and the system reaches break-even somewhere between year eight and year twelve for most UK homes. After that, generation is essentially free.
