Everything homeowners need to know before installing solar panels and battery storage. Learn how solar works, what affects savings, and how to choose trusted UK installers.
Get Free Solar EstimateSolar panels generate electricity during daylight hours. This energy can power your home, charge a battery, or reduce the electricity you buy from the grid.
Panels collect daylight from your roof throughout the day.
Panels convert daylight into usable electricity for your home.
Unused solar energy can be stored for evening use.
Your home uses solar power to reduce grid electricity use.
Most UK homes can benefit from solar, but the best system depends on your roof, energy use, shading, and future plans.
South-facing roofs usually perform best, but east and west-facing roofs can still work well.
More usable roof space allows more panels, which can improve energy generation.
Trees, chimneys, dormers, or nearby buildings can reduce panel performance.
Homes using more electricity may benefit from larger solar systems and batteries.
If you use more energy in the evening, battery storage may be useful.
EV chargers, heat pumps, or growing household usage can affect the ideal system size.
A solar battery stores excess energy generated during the day so you can use it later, especially in the evening when electricity demand is often higher.
Instead of exporting unused energy, you can store it for later.
Batteries can help reduce electricity bought from the grid at night.
Some tariffs allow batteries to charge at cheaper off-peak times.
Solar and battery systems should always be assessed and installed by qualified professionals who follow recognised UK standards.
MCS is a major UK certification scheme for renewable energy products and installers.
RECC helps protect consumers by setting standards for renewable energy sales and contracts.
HIES provides consumer protection and support for home energy installations.
NAPIT supports electrical safety and installer competence across the UK.
NICEIC registration helps show electrical work is carried out to recognised standards.
Always check workmanship warranties, product warranties, and installer insurance.
ReLeaf Energy provides an educational estimate only. A qualified installer should always complete a full property assessment before installation decisions are made.
Yes. They still generate electricity during daylight, although output is usually lower than summer.
Most home solar installations are permitted development, but listed buildings or conservation areas may need checks.
No. It depends on your usage pattern, budget, tariffs, and how much energy you use in the evening.
Many panels have long performance warranties, often around 20–25 years or more.
Yes. Solar can support EV charging, especially if you charge during the day or use battery storage.
It gives a useful starting estimate. A full installer survey is needed for final design and pricing.
