How to calculate annual energy output of a photovoltaic solar installation?
To calculate the annual energy output of a photovoltaic solar installation, you need to determine the yield (r) of the solar panel. r is the yield given by the ratio of electrical power (in kWp) of one solar panel divided by the area of one panel. For example, a PV module of 250 Wp with an area of 1.6 m2 has a yield of 15.6%.
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.
