Soly mainly makes use of Jinko Solar Panels (visit product page). One panel has the capacity of 350WP (watt-peak). The average kWh (kilowatt per hour) will vary between the seasons of high and low sun peak. However, let’s say on a good day, you average 8 hours of sunlight. Multiply that by 350 watts from a solar panel =  2800 watts or roughly 3 kWh per panel per day.
