Rooftop Photovoltaics: Germany's New Installed Capacity Main Force

Oct 10, 2020

The German Electric Power Company stated that in recent years, renewable energy power has received increasing attention in Germany and has gradually become the focus of the future development of the German energy industry. With the increasing proportion of renewable energy power, it is necessary to increase a large amount of renewable energy power in order to meet the new power demand in the future.


Among all types of renewable energy sources, photovoltaics will become the "handsman" of the German power system. "Photovoltaic Magazine" quoted the opinion of EnergyBrainpool, a German industry consulting organization, and pointed out that at present, household rooftop photovoltaic is the most popular and accepted form of renewable energy in Germany, and it will play an important role in the future power system of Germany. The key to the success of Germany's energy transition lies. According to estimates, the potential developable scale of roof photovoltaic power generation projects for households in Germany can reach hundreds of gigawatts.


The German power company also emphasized that in the next 10 years, household rooftop photovoltaics with installed capacity below 100 kilowatts will be the main force in Germany's new power generation capacity, which will help Germany to achieve climate change goals and prevent Germany from experiencing a shortage of electricity supply.


The latest data released by the German Federal Energy and Water Industry Association shows that in the first half of 2019, the proportion of renewable energy power generation in Germany has reached 44%, setting a new historical record. According to the energy transition goals issued by the German government in 2019, by 2030, the proportion of renewable energy power generation in Germany needs to reach 65%. Some critics pointed out that if the German government does not carry out reforms, it is likely to miss the opportunity to complete this goal.


Against this background, the German government has made continuous actions this year: first, in the first half of the year, the ceiling for photovoltaic power generation was lifted, and the completion of photovoltaic projects that were blocked due to the new crown pneumonia epidemic was also allowed to be postponed; later, a new version of the photovoltaic development plan was announced in early September. -In 2028, public bidding will be conducted for photovoltaic power generation projects with a total installed capacity of 18.8 GW. The minimum annual bidding scale for photovoltaic power generation projects is 1.9 GW and the highest is 2.8 GW.


However, EnergyBrainpool still believes that the current plan is not enough for Germany to successfully achieve its climate change goals. According to data from the German Federal Network Administration, from 2018 to 2019, the newly installed capacity of photovoltaic power generation in Germany was about 3 GW and 4 GW respectively; in the first 7 months of this year, the newly installed capacity of photovoltaic power generation in Germany was only about 2.8 GW. . In contrast to Germany's demand for new clean power installations in the next 10 years, the growth rate of installed photovoltaic power generation in Germany in recent years is far from sufficient.


EnergyBrainpool stated that Germany should raise the target for new installed capacity of photovoltaic power generation from the current 5 gigawatts per year to 6-12 gigawatts; after 2030, this increase must be at least 14 gigawatts.


To this end, EnergyBrainpool recommends that the German government introduce a mandatory implementation policy, requiring the installation of rooftop photovoltaic systems on all new buildings. At the same time, the agency also called for strengthening the upgrading of power supporting facilities such as smart meters, simplifying the online sales process of surplus electricity for rooftop photovoltaic systems with a scale of less than 100 kilowatts, and promoting the development of unsubsidized rooftop photovoltaic projects in a timely manner.
