Technical FAQs 4

Do solar panels need direct sunlight?

They may be covered by shade from surrounding buildings or trees, are turned away from the sun, or are simply affected by weather conditions like clouds, rain, or snow. Solar panels do not need direct sunlight to work. Most rooftop solar panels start producing electricity shortly after sunrise on a clear day.

Do solar panels work without sunlight?

There will, however, be a drop in performance in the absence of direct sunlight. That’s because solar panels need 1000 W/m 2 of sunlight to reach their peak output; that much sunlight can only be achieved when there is direct sunlight shining. Do solar panels work in the shade?

Do solar panels reflect sunlight?

Remember that solar panels turn sunlight into electricity, so it’s best for them to absorb, not reflect, as much sunlight as they can. To that end, they’re coated with anti-reflective material to ensure better efficiency.

Can solar panels work in the shade?

Yes, solar panels can work in the shade, but they will generate less electric current than they would under optimum conditions. The exact impact of shading on your solar power system depends on these factors: Duration of the shading: The longer your solar panels are under shade, the bigger the drop in electricity production.
