What happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect engineers working on the grid). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
Do I need a smart meter for solar panels?

What roof direction is best for solar panels in Seven Sisters?
South-facing roofs produce the most electricity (100% of potential). South-east and south-west roofs produce around 95%. East or west-facing roofs still produce 80-85%. North-facing roofs are generally not recommended for solar panels in the UK.
Do solar panels work in winter in Neath Port Talbot?
Yes, solar panels generate electricity all year round. While output is lower in winter, Neath Port Talbot still receives usable daylight hours even in December. Annual generation figures (3,480 kWh for a 4kWp system) already account for seasonal variation.

Solar panels stay with the property as a permanent fixture. They add value to your home for the next buyer. Your installer can transfer monitoring accounts to the new owner.
Do I need to clean my solar panels?
In most cases, rain keeps solar panels clean enough in the UK. If your panels are near trees or at a low angle, an annual clean may improve output by 2-5%. Never use abrasive materials. A soft brush and water is sufficient.
