1. Solar Panels Work in Cloudy Weather
Solar panels generate electricity from daylight, not just direct sunlight. Even on overcast days typical of the UK, panels produce 10-25% of their rated output. Over a year, a well-positioned system in Greater Manchester generates 850-1,000 kWh per kWp installed.
2. You Can Earn Money from Excess Energy
The Smart Export Guarantee (SEG) pays you for surplus electricity exported to the grid. Rates range from 3-15p per kWh depending on your tariff. Combined with self-consumption savings, solar delivers excellent financial returns.
3. Solar Panels Last 25+ Years
Modern solar panels are warranted to produce at least 80% of rated output after 25 years. With no moving parts, maintenance is minimal — typically just an annual visual inspection and occasional clean.
4. Battery Storage Maximises Your Savings
Adding a battery lets you store daytime solar energy for evening use, increasing self-consumption from 30-40% to 60-80%. This can add £200-£550 to your annual savings.
5. There's No VAT on Home Solar
Since April 2022, domestic solar panel installations are zero-rated for VAT in the UK. This 20% saving makes solar even more affordable, reducing the payback period significantly.
