PV for power generation

Photovoltaic systems on your own roof are not only free of CO2 emissions, they also have many other advantages: they produce electricity even when there is little sunlight and enable a power supply that is independent of the local power grid. Produced electricity can be used at night and/or in bad weather by means of solar storage. In contrast to fossil and renewable fuels, there are no transport costs and emissions. They are also quiet, require little maintenance and have a relatively long service life. Are there any disadvantages? Well, there is one: If the sun doesn’t shine, there’s no electricity.
