Solar output drop in winter
How much does output drop in winter?
Short answer
Winter days are shorter and the sun is lower. Add smog, and a system in Punjab often produces a good deal less in December–January than in April–June. Expect a noticeable drop, not a failure. Adjusting the tilt and keeping the panels clean helps.
More detail
In smog weeks, a quick panel wash can bring back part of the lost output. A sudden drop on a clear day is different: check the app and the inverter screen, and message us if it doesn't recover. Solar output in Lahore smog
