10.08.2021 | Reliable facts on solar energy
What is the state of solar energy in Europe and worldwide? How are prices developing? What materials are being used? And when is the amount of energy invested in the construction of a power plant amortised ("Energy Payback Time")? These facts are compiled by the renowned Fraunhofer Institute for Solar Energy Systems ISE. Here you can gain an insight into the latest "Photovoltaics Report".
The aim of the report is to prepare data from a wide range of sources in one report and thus make it easily accessible. In addition to updated figures on photovoltaic production, installation and performance, the current report also contains data that has been compiled for the first time. For example, the energy payback time. This indicates the period of time that a solar system must be operated in order to provide the amount of energy invested. The report shows the historical development as well as comparable values for different regions. For example, the energy payback time for roof systems with silicon solar modules produced in China and an efficiency of 19.9 % in Europe is 1 to 1.3 years. The world leader is India (0.44 years), at the other end of the scale is Canada with 1.42 years.
The report also includes a new European overview map showing the production capacities along the PV value chain for materials, solar cells and PV modules in the individual member states. This shows that especially in the module sector, production facilities are in operation in many European countries - with a total capacity of about 7000 MW per year.
