Weather & Punjab conditions · Faisalabad, Lahore, Punjab
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.
