It is worth being clear about the seasons. Solar panels generate most from spring to early autumn, when a heat pump is mainly heating hot water. In December and January, when heating demand peaks, a typical roof produces only a small fraction of its summer output and covers little of the heat pump's needs. The strongest fit is daytime hot water heating for much of the year, with a battery or a time-of-use tariff helping in winter.
We plan heat pump and solar electrics together for County Fermanagh homes so the consumer unit is upgraded only once. Homes in County Fermanagh with existing panels can often have the heat pump set to heat water from their daytime output. Across County Fermanagh and County Fermanagh, winter solar output is modest, so our heat pump designs never rely on it for heating.
Who it suits
- Homes with existing solar PV that currently export much of their output
- Homeowners planning a heat pump who want to add panels at the same time
- Homes with a roof facing anywhere from east through south to west, with little shading
- Households at home during the day or with flexible hot water timing
Grants and rules for heat pumps in Northern Ireland
Northern Ireland does not have a dedicated heat pump grant for homeowners at present, and the Boiler Upgrade Scheme does not apply here. Heat pumps have sometimes been funded through the Northern Ireland Sustainable Energy Programme, so it is worth checking what is open when you enquire about a home in County Fermanagh.
There is no VAT on installing a heat pump in Northern Ireland until 31 March 2027, the same as in Great Britain. Planning and building control here follow Northern Ireland's own rules, so the survey checks the unit position against them.
Prices
Solar panels and batteries are quoted separately after a roof survey. For heat pump system prices see the guide prices.

Heat pumps with solar panels and batteries questions
Can my roof take solar panels?
Most pitched roofs in sound condition can take solar panels, but every roof needs checking. The survey looks at orientation, pitch, shading, roof covering and structure, plus access for scaffolding. Flat roofs can use angled mounting frames. The survey also checks where the inverter and any battery would go and how cables would reach your consumer unit.
Should I fit solar panels before or after a heat pump?
Either order works, but planning both together helps. Knowing the heat pump's electricity use helps size the panels and any battery, and the electrical work for both can be coordinated, including the consumer unit and any notification to the network operator. If you already have panels, the heat pump controls can be set to use their output for hot water.
Can solar panels run my heat pump in winter?
Only partly. In midwinter, solar panels typically generate a small fraction of their summer output, and the shortest days coincide with the highest heating demand. Panels may help on bright winter afternoons, but most winter heating will run on grid electricity or a battery charged from a cheaper overnight tariff. Solar contributes most to hot water from spring to autumn.
Do I need a battery to benefit from solar with a heat pump?
No. Without a battery you can still use solar generation directly by timing hot water heating for the middle of the day. A battery adds flexibility by storing surplus for the evening, or by charging from a cheaper overnight tariff in winter. Whether it suits you depends on how much you would otherwise export and on your tariff.
