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.

Right now

Measured at 16:20 Bergen time, 27 min ago. Fetched from Tigo every 15 minutes.

Right nowor a period:

The tilted frame seen from the lawn, photographed on 17 September 2026. Upper row: 6 monocrystalline panels of 280 Wp. Lower row: 6 polycrystalline panels of 275 Wp.

Tint: share of each panel of its own peak power.under 5 %5 to 20 %20 to 40 %40 to 70 %70 % and over

Power of each optimised panel, its peak power, and the share of its own peak power it is producing.

How even is each row

How much less the weakest panel of a row produces than the strongest, in percent of the strongest. This is a calculation made from the twelve measurements above, not a measurement of its own.

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. A single reading can be thrown off by a passing cloud; a period is a better test.

Upper row, monocrystalline

The best panel of this row is under 10 percent of its peak power, so there is too little light for the comparison to mean anything. Come back in daylight.

Lower row, polycrystalline

The best panel of this row is under 10 percent of its peak power, so there is too little light for the comparison to mean anything. Come back in daylight.

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.
