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.
Roof orientation and shading vary street by street in Clwyd, so solar is assessed on each roof individually. Across Clwyd and Clwyd, winter solar output is modest, so our heat pump designs never rely on it for heating. For Clwyd households out during the day, a battery can carry daytime solar into the evening heating period.
Who it suits
- Homeowners planning a heat pump who want to add panels at the same time
- Households considering a battery to store daytime or cheaper overnight electricity
- Households at home during the day or with flexible hot water timing
- Homes with a roof facing anywhere from east through south to west, with little shading
Grants and rules for heat pumps in Wales
Homes in Clwyd can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.
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
How much do solar panels and a battery cost with a heat pump?
Solar PV and batteries are quoted separately from the heat pump, because the price depends on your roof, the number of panels, scaffolding, the inverter and any battery size. We survey the roof and give a written quote for that part of the work. The heat pump itself is priced from its own guide ranges, shown on our prices page.
Is a solar diverter useful with a heat pump?
It can be, but less so than with a gas boiler. A diverter heats water through the immersion heater, which turns one unit of electricity into one unit of heat, while a heat pump typically makes around three. Scheduling the heat pump to heat water at midday usually uses solar more efficiently, with a diverter adding top-ups on very sunny days.
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.
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.
