A south-facing system here produces around 3,200 to 3,600 kWh per year. That's enough to offset the majority of an average household's electricity usage.

The city has a large stock of 1930s semi-detached homes, particularly in Erdington, Hall Green, and Solihull. Wide, pitched roofs. Minimal shading. Most can accommodate 12 to 15 panels without any issues.
Post-war estates and newer developments in areas like Longbridge also offer good roof profiles. With 43% of Birmingham homes still rated below EPC C, solar panels are a practical way to improve your energy rating alongside insulation upgrades.
For most Birmingham homeowners on mains gas, solar panels are the logical first investment. They reduce your electricity bill from day one. If you later install a heat pump, the panels help offset the increased electricity demand.
Properties with poor insulation or outdated heating systems may benefit more from a heat pump and fabric improvements first. Our solar panels vs heat pumps comparison walks through the decision. Our solar panels vs heat pumps comparison walks through the decision in detail.
Two schemes are worth knowing about. ECO4 can fund a full solar installation if your household receives qualifying benefits. Everyone else gets 0% VAT on domestic solar, which knocks roughly £1,000 to £1,500 off the invoice. Our guide to solar panel grants covers eligibility and how to apply.
