![]() The high output, both in the short-term around midday and in the long-term during summer, is offset by a reciprocally lower or non-existent output during the winter and at night, respectively, highlighting the need for reliable storage technology to complement renewables expansion. However, sunny weather and hot temperatures are not automatically leading to higher solar power output, as solar modules lose electric tension when they become hot, which brings down their capacity despite the stronger radiation. Solar power influx at peak demand time - around 12pm - has a stabilising effect on the grid but also greatly reduces profit margins for power providers, who in the past were able to charge the highest prices at this time of the day, when demand reaches a maximum and supply used to be scarce. Despite experiencing a comparatively cloudy summer, Germany’s solar PV installations between January and August 2021 generated roughly the same as during the same period in the previous year, when much more sunshine hours were recorded, thanks to capacity expansion. Overall, solar power arrays produced about 51 TWh of power in 2021.Īdding more capacity also acts as a check against oscillating solar power production levels due to weather effects. At about noon, when both sun intensity and usually also power consumption are at peak levels, solar power can account for more than 40 percent of Germany’s power production. In 2020, solar power reached new record weekly share of 23 percent over a whole week and a daily record of almost 28 percent, research institute Fraunhofer ISE found. ![]() In June, they generated 7.99 terawatt hours of electricity - more than ever before in a single month - accounting for 20.6 percent of net electricity generation. Between March and August 2021, solar panels generated more power than all of the country's hard coal-fired plants combined. The technology can contribute a much greater share to the German power mix at particularly sunny times. Solar power’s global share in power generation surpassed two percent for the first time in 2019, according to the IEA. In 2021, all solar operators together produced about ten percent of the country’s net power consumption, out of a total renewables share of just under 46 percent, according to research institute Fraunhofer ISE. In contrast to conventional energy systems focused on big and centralised producers, thousands of small solar panel operators have become an important part of the German energy system. With an installed capacity of nearly 60 gigawatt (GW) in 2021, the country ranked 4th globally after leading the fied for several years, according to the International Renewable Energy Agency (IRENA). Number of solar arrays installed: 2 million (2020)ĭespite being among the countries with the least sunshine hours, Germany is one of the largest solar power producers in the world.
