Can You Run a Heat Pump on Solar Panels?
Yes, you can run a heat pump on solar panels, but in most UK homes that means solar helps power part of the system rather than every hour of heating demand all year round. Energy Saving Trust says heat pumps can generate around three units of heat per unit of electricity used, which is why solar-generated electricity can be particularly valuable when linked to heating.
The combination is therefore very strong, but it is not a promise of fully off-grid heating.
For the wider economics, read our heat pump solar ROI guide, heat pump + solar combo guide, and solar battery storage article.
How Does the Combination Work in Practice?
In practice, the solar system generates electricity during daylight hours and the heat pump uses electricity whenever the home needs heating or hot water. Energy Saving Trust says the average domestic solar system is around 3.5kWp, and in suitable homes that can meaningfully offset part of the heat pump’s imported electricity over the year.
| System | Main role |
|---|---|
| Solar panels | Generate electricity in daylight |
| Heat pump | Uses electricity for heating and hot water |
| Battery | Helps shift some solar into evening use |
The stronger the self-consumption, the better the economics usually become.
Does Solar Cover All Heat Pump Use?
Usually no, especially not in winter when heating demand is highest and solar output is weakest. That is why the right expectation is “solar offsets part of the heat pump electricity” rather than “solar fully powers the heating system all year”.
Even so, the combination can still be very powerful financially and strategically because it links efficient heating with on-site generation.
What Does This Mean in London, Surrey, and TW Homes?
In London, Surrey, and TW homes, the heat pump and solar combination is often strongest in owner-occupied houses with good roof space and medium-to-high heat demand. MCS reported more than 120,000 certified solar installations and more than 30,000 certified heat pump installations in the first half of 2025, which shows how mainstream this combined pathway has become.
Terraces, semis, and detached houses can all benefit if the roof and layout are right.
How Electromatic Can Help
If you want to know whether your heat pump could run effectively with solar on your property, Electromatic can assess the roof, the likely generation, and the heating demand together. That gives you a practical answer instead of a vague claim about “free heating”.

Frequently Asked Questions
Can solar panels power a heat pump directly?
Yes, at times, but most homes still import some electricity from the grid as well.
Does solar cover heat pump use in winter?
Usually only partly, because winter solar output is lower while heating demand is higher.
Is battery storage useful with a heat pump and solar?
Often yes. It can help you keep more of your own solar electricity for later use.
Is the heat pump and solar combo worth it?
Often yes in suitable houses, especially where the homeowner wants a stronger all-electric energy strategy.
Can I install the heat pump first and solar later?
Yes. Many homes phase the project that way, provided the wider design direction is thought through properly.
