So far, as of 5th November 2025 we have generated 12.78MW of solar energy. We’ve exported 9.4MW of electricity back to the grid.
The savings per year is calculating as £2,442 and the break-even (or cost recovered) time is 5-years 7-months. After that it’s all cash-back/free electricity.
If you look at the measured performance of the strings, considering that the rear string (which is north-north-west facing) is bonus generation in all but winter and thus its costs are primarily for additional panels, then you can see how each string is contributing:
| Panels | 24 | String Cost | System % | Savings | Break Even | Generation (kWh) | Export (£) |
| Front | 8 | £ 5,621 | 42% | £ 1,019 | 5-yrs 6-mths | 5330 | £ 647 |
| Garage + O | 8 | £ 6,041 | 39% | £ 945 | 6-yrs 4-mths | 4944 | £ 601 |
| Rear | 8 | £ 2,080 | 20% | £ 479 | 4-yrs 4-mths | 2505 | £ 304 |
| 100% | £ 2,442 | 12779 | £ 1552 |
