How do I calculate the size of a solar photovoltaic system?

To calculate the size of a solar photovoltaic system, first divide your daily kWh energy requirement by your peak sun-hours to get the kW output you need. Then, divide the kW output by the efficiency of your solar panels to get the total number of solar panels for your system.
