What is solar photovoltaic (PV) power generation?
Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.

What is PV power generation?
PV power generation uses solar light, and uses solar cells to convert light energy into electrical energy. PV power generation consists of three main subsystems: PV array, DC-AC converter (inverter) and battery energy storage system. PV Power Generation is a system that uses the photoelectric effect to turn energy from the sun into electricity.
How many kWh do solar panels generate a year?
We will also calculate how many kWh per year do solar panels generate and how much does that save you on electricity. Example: 300W solar panels in San Francisco, California, get an average of 5.4 peak sun hours per day. That means it will produce 0.3kW × 5.4h/day × 0.75 = 1.215 kWh per day. That’s about 444 kWh per year.
