Avg. generation of 1000 Watt
solar panels is 4-5 units/day. There could be multiple impact of lower power generation from solar panels 1) The latitude angle changes in winter, while
solar systems are installed as per latitude angel summer season. 2) Dust over solar panels impacts the generation very high, 3) The distance of wire from Solar panels to Inverter and Lower rating of wire for passing of current 4) If consumption is lower, Solar panel will generate lower power, generally in winters home consumption goes low 5) Availability of sun light which is also called Intensity of sun, Radion which is generally lower in Winters.
