How much electricity does a photovoltaic system produce a year?

Annual electricity production is measured in kWh (kilowatt hours). One kilowatt of peak photovoltaic power generates nearly 1,000 kilowatt-hours of electricity per year. If you are interested in this topic, you may be asking yourself: What performance should the system provide in the best case scenario?

How much energy does a PV system produce?

The average output of a PV system for single-family and multi-family dwellings is approximately 5 to 10 kWp. This corresponds to 800 to 1,200 kWh per kW peak. The amount of solar energy generated by PV depends on a number of factors, such as the location of the PV system and the performance and orientation of the PV modules.

How much solar energy do you need for a photovoltaic system?

To make the system economically worthwhile, you should use as much solar energy as possible yourself. Due to the reduced feed-in tariff, it is no longer worthwhile to supply the public grid. For a 4 kWp photovoltaic system, you need 12-13 photovoltaic modules with a peak output of almost 320 watts. The invoice for this:

How much solar energy does a kW peak produce?

This corresponds to 800 to 1,200 kWh per kW peak. The amount of solar energy generated by PV depends on a number of factors, such as the location of the PV system and the performance and orientation of the PV modules. In order to calculate the optimal PV performance, you need to know how much electricity you use.

How much power does a PV module produce?

Modern modules have a PV output of between 300 and 500 Wp per module. PV systems for single-family and multi-family homes typically use PV modules with an output of 300 Wp. These modules are less expensive than high-performance modules of 400 Wp or higher.

How much solar energy does Germany generate a year?

The average photovoltaic capacity in Germany is 1,000 kWh per installed kWp per year. A 6 kWp system therefore generates 6,000 kWh of solar energy per year. Southern Germany generates more than 1,000 kWh. In the north, the output of the solar system is lower. In our table you can see the average annual output in different cities.
