Why Solarpunk
One home. Three systems that earn more together than apart.
A heat pump turns one unit of electricity into three or four of heat. Solar makes that electricity for nothing from March to October. A battery holds it — and cheap overnight power in winter — for the hours the grid charges most. Each pays on its own; linked, each makes the others pay faster.
01 · Heat pump · the biggest number
Start where the grant is: £7,500 towards the heating.
£7,500 grant in England and Wales · £9,000 on oil or LPG until 31 March 2027, paid straight to the installer. Heating is most of a home's energy, so it is where the carbon and the money are — and a well-designed heat pump runs at 300–400% efficiency where a boiler tops out near 90%.
Design decides everything: a room-by-room heat loss survey, radiators sized for a low flow temperature, controls left alone. Done well it heats an old house; done badly it costs as much as gas.
02 · Solar · the free electricity
Your roof makes the electricity the heat pump runs on.
About 4,900 kWh a year from twelve panels, paying back in 9–14 years — 0% VAT until 31 March 2027, and export paid for what you don't use. On its own a typical home uses about 19% of its solar as it is made; with a battery that rises to 48%.
South makes the most per panel, east–west about 80%, and since 27 August 2026 renters and flats have a legal plug-in route. Most of the yield lands outside the heating season — which is exactly when the heat pump is making hot water and the car is charging.
03 · Battery · the hours that cost most
Buy electricity when it is 3× cheaper. Use it when it isn't.
Six cheap hours at 8.6p against 26.3p in the day. A battery fills on the cheap rate and from the solar surplus, then runs the house — and the heat pump — through the evening peak. In winter, when the panels make a tenth of summer, the overnight rate carries it.
Sized to what you use in the expensive hours, not to the biggest unit that fits. With a backup gateway it keeps the lights, the router and the heating on in a power cut.
What it adds up to
A home that makes, stores and manages its own energy.
Solarpunk is the practical version of a hopeful future: ordinary houses, quietly running on sunlight and cheap hours, with the paperwork in order. This is what the three systems buy you beyond the bills.
Energy independence
Less bought from the grid, and what you do buy bought in the cheap hours. The price cap moves every quarter; a roof and a battery make the moves matter less. With backup, a power cut is something you read about.
A lighter footprint
Heating is most of a home's carbon. A heat pump moves it off gas or oil; solar and a battery mean it runs on your own sunlight and on the grid's cleanest, cheapest hours — which are the same hours.
Ready for what's next
An electric car charges in the cheap window; a smart tariff turns the whole house into a small power station. Systems fitted in the right order — and documented — add up to a home that is cheaper to run and easier to sell.
Every number on this page comes from a named source, checked 24 September 2026: Ofgem, the Energy Saving Trust, DESNZ, MCS and the tariffs themselves. Always a range, never a single figure.
