On average, a solar panel can output about 400 watts of power under direct sunlight, and produce about 2 kilowatt-hours (kWh) of energy per day.

Divide your system size (kW) by panel wattage. For 6kW with 400W panels: 6000 ÷ 400 = 15 panels. 8 = 24 kWh/day or ~720 kWh/month.

Flat solar panels work by using the photovoltaic effect, which is the process that converts sunlight into electricity. When sunlight hits the solar cells in the panel, it excites electrons, creating an electric current. This is how energy is captured and transformed for use.
