Key figures and records
What the installation can do, what it has actually done, and how the three panel technologies compare when they are measured side by side.

Specific yield, array by array
A bigger array naturally produces more, so comparing raw kilowatt hours says little. Dividing the energy by the peak power of the array gives kWh per kWp, which is the fair comparison: same weather, same place, same period.
Since recording started
| Array | Wp | kWh | kWh/kWp |
|---|---|---|---|
| Solar power, array 1 (monocrystalline) | 1 680 | 103.1 | 61.4 |
| Solar power, array 2 (polycrystalline) | 1 650 | 93.5 | 56.7 |
| Solar power, array 3 (vertical, east and west) | 1 440 | 15.7 | 10.9 |
Array 3 is mounted vertically, facing east and west, so it collects less in total but more in the early morning and the late evening. See the lab for why that matters this far north.
Year by year
| Year | Energy (kWh) | Days measured | kWh per kWp |
|---|---|---|---|
| 2026 | 212.3 | 50 | 44.5 |
A year with few days measured is not comparable with a complete one. The number of days is shown for that reason.
