Panel by panel
Twelve of the 24 panels have their own optimiser, so each one is measured on its own. Here they are on a photo of the frame, right now or over any period you choose.

How even is each row
The six panels of a row see the same sky, so they should produce about the same share of their peak power. One that falls behind points to shade, dirt, snow or a fault. Over a period, a passing cloud no longer matters.
Upper row, monocrystalline
- Strongest
- M2, 1 141 Wh/kWp
- Weakest
- M6, 1 065 Wh/kWp
- Difference (calculated)
- 7 % less
6 of the 6 panels of this row answered. The weakest, M6, produces 7 percent less than the strongest, M2 (1 065 Wh/kWp against 1 141 Wh/kWp). Over a period, a difference above about 5 percent deserves a look at that panel.
Lower row, polycrystalline
- Strongest
- P1, 1 778 Wh/kWp
- Weakest
- P5, 1 623 Wh/kWp
- Difference (calculated)
- 9 % less
6 of the 6 panels of this row answered. The weakest, P5, produces 9 percent less than the strongest, P1 (1 623 Wh/kWp against 1 778 Wh/kWp). Over a period, a difference above about 5 percent deserves a look at that panel.
How to read these numbers
- Direct current, before the inverter. The inverter loses a few percent, so the sum of these panels is more than the lab delivers. The real production is on the live page.
- The vertical array is not shown. Its twelve modules have no optimiser, so they are only measured together, as array 3.
- Read through Tigo. The optimisers report to the Tigo cloud and this site reads the values from there.
Each panel's history can be charted and downloaded on the data page. The three arrays are compared on key figures and records.
