A solar savings calculator estimates annual financial benefit from generating your own electricity, based on system size, peak sun hours, and electricity tariff.
- 1Daily generation = Panels × Wattage × Sun hours / 1,000 (kWh)
- 2Annual = Daily × 365
- 3Saving = Annual kWh × Electricity rate (self-consumed portion)
- 4Export tariff adds income from surplus electricity
10 × 400W panels, 3.5 sun hours/day, £0.28/kWh=Daily: 14 kWh; Annual: 5,110 kWh; Savings ≈ £1,431/yr
| Panels | System kW | Annual kWh | Saving (£0.28) |
