We compare your system's real output with what it should produce given the actual weather at your location — and tell you straight whether something's wrong. Not a chart to decode, but a clear answer.

We don't guess. We compare real output against the PVGIS model — a public European calculation (EC Joint Research Centre) that, for your exact location, panel tilt and orientation, factors in the actual weather. The gap between those two numbers is the basis of every verdict.
From a hand-entered number we can do one thing. From a connected inverter we read every day, we see much deeper — down to individual panels.
Just location, power, and annual or monthly output.
Connect once, then Slunora reads on its own. Deeper findings are rolling out gradually.
Tracking apps bury you in charts and leave the conclusion to you. We take the last step — a clear verdict, the evidence behind it, and what to do next. You get charts too, but as a complement, not homework.
Check my systemWithout a key value we won't label the result, but we don't fill it in or replace it with zero. We'd rather say “we don't know” than give false certainty.
Every finding has evidence and a confidence — high, medium, low. The verdict matches the input quality, not the marketing.
Economic estimates always come as a range with stated assumptions — never a single precise number we can't stand behind.
