Yes. A home battery (typically 5-10 kWh) stores excess solar electricity for evening use. This increases your self-consumption from around 30-40% to 60-80%. Batteries currently cost £3,000-£6,000 and also benefit from 0% VAT.
Do solar panels work in winter in Belfast?
Yes, solar panels generate electricity all year round. While output is lower in winter, Belfast still receives usable daylight hours even in December. Annual generation figures (3,260 kWh for a 4kWp system) already account for seasonal variation.
What is an EPC assessment and do I need one?
