How much you save on your electricity bill depends on how much energy your solar panels produce and how much of that energy you use in your home. But here’s a simple way to understand it:
🔋 Typical Savings Example
Let’s say your current electricity bill is £100 per month (or £1,200 per year).
If your solar system is designed to cover about 75%–90% of your usage:
- You could save around £900–£1,080 per year
- That’s about £75–£90 per month
If you also install a battery, you can store unused solar energy and use it at night or during peak-rate hours—boosting your savings even more.
☀️ Quick Savings Estimate Table
| Current Bill | % Covered by Solar | Estimated Yearly Savings |
| £1,200 | 80% | £960 |
| £1,500 | 85% | £1,275 |
| £2,000 | 90% | £1,800 |
📈 Extra Savings from Smart Export Guarantee (SEG)
If your panels make more power than you use, you can sell the extra back to the grid through the SEG scheme, earning even more (up to £100–£300+ per year, depending on your system and tariff).
✅ Summary
With a good-sized solar system, you can expect to save 60% to 90% on your electricity bill each year—and possibly earn extra through export payments if you produce more than you use.
