Do solar panels work in winter in Bedfordshire?
Yes, solar panels generate electricity all year round. While output is lower in winter, Bedfordshire still receives usable daylight hours even in December. Annual generation figures (3,760 kWh for a 4kWp system) already account for seasonal variation.
What is the Smart Export Guarantee (SEG)?

Can I get solar panels on an east or west facing roof in Luton?
