The Financial Case
A typical 4kW solar system costs £5,500-£7,000 and saves £500-£800/year on electricity bills. With SEG income of £50-£150/year, payback is typically 6-9 years. After payback, you enjoy 15-20+ years of near-free electricity.
Factors That Affect Value
Your savings depend on roof orientation (south is best), shading, how much electricity you use during the day, your current energy tariff, and whether you add battery storage. Even east/west roofs generate 80-85% of a south-facing system.
The Verdict
For most UK homeowners, solar panels are an excellent investment offering better returns than savings accounts. They hedge against rising energy costs, add property value, and reduce your carbon footprint. With 0% VAT and available finance, the barrier to entry has never been lower.
