My Best Solar Days Are All in the Last Two Months

Something quietly satisfying has happened to my little garden array as spring tipped into summer: every one of my twenty best solar days has landed in the last two months — and they all clear 3 kWh. Not one of my best days predates late April. The whole top of the leaderboard is new.

The daily average tells the same story louder. Through the dead of last winter the panels limped along — December averaged 0.15 kWh a day, January barely better at 0.23. By April that had jumped to 2.27, May 2.31, June holding near 2.25. Since the array reached full size at the end of April it's run at 2.33 kWh a day — more than double the 1.04 kWh lifetime average, which the winter months drag right down.

Two things got me here, at opposite ends of the cold. I added a pair of N-type panels on 23 November 2025 — straight into the darkest weeks, so they did almost nothing at first and I took the upgrade on faith. The seventh panel went up on 30 April 2026, just as the days were stretching out. It's the combination — more glass plus a higher, longer sun — that lit the numbers up, not either alone.

The line graph has a proper bathtub shape: a summer-2025 shoulder, a long slide into a near-flat winter trough, then a steep climb back out from March. The contribution grid is the bit I keep staring at — watching it go from dim and sparse in December to dense, bright amber through May and June, each square a day the panels actually did something.

None of this is going to power the flat — it's a 700-watt array on salvaged frames at ground level in the garden, and on its best day ever (3.43 kWh, on 27 May) it brushes a ceiling the single charge controller imposes. But that's not the point. The trend line climbs, the grid fills in, and a thing I bolted together in a garden keeps quietly turning daylight into something useful.
