Solar panels that produce hot water are known as solar thermal collectors or solar hot water collectors. Solar panels that produce electricity are known as solar photovoltaic (PV) modules. These panels

Advice on installing solar water heating

Solar water heating systems, or solar thermal systems, use energy from the sun to warm water for storage in a hot water cylinder or thermal store. Because the amount of available solar energy varies throughout the year, a solar water heating system won''t provide 100% of the hot water required throughout the year.

That said, the rate at which solar panels generate electricity varies depending on the amount of direct sunlight and the quality, size, number and location of panels in use. Even in winter, solar panel technology is still effective; at one point in February 2022, solar was providing more than 20% of the UK’s electricity.1

Will solar panels generate enough electricity year-round?

Whether they'll generate enough electricity for your home year-round will depend on: if your solar panel system works in a power cut. It may be more realistic to think about whether you can be self-sufficient for the brighter parts of the year, and then top up your energy use from the grid at other times.

Do solar panels generate electricity at night?

Solar panels generate no electricity at night time. Solar panels can't store energy, so you have to use the electricity they generate when the sun is shining. You need batteries to store the energy generated. These are expensive. – Solar cells convert the light from the sun into electricity.
