Output check
We log output before and after, the difference is there in writing.
Output check
Loss from dirt happens slowly and nobody notices: the panel looks clean and the bill creeps up a little at a time. Before washing, we note what the inverter is producing; after washing, we note it again. If the difference does not justify the clean, we say so.
- Inverter reading before and after the clean
- Written, dated record handed over
- We flag shading, faults or an underperforming panel
- An honest recommendation on when to wash again
