How many 60w solar panels makes 1kw?

Answer 1

A 60 watt panel is capable of producing about 50 watts in direct sunlight.

Twenty panels producing 50 watts each would give us 1 Kw.

If we are not considering the measurement losses and just go with rated power, the number is reduced to 17 panels.

If we are talking 1 kilowatt hour, that can be done with a single panel but it would take twenty hours of sunlight.

In my area, that would be about ten days, on average at standard temperature. Some areas have more hours of full sunlight and cooler temperatures, so that amount would be reduced.
