Soaring energy prices, growing environmental awareness, electrification of transportation and increasing user demand have driven Germany to accelerate the installation and deployment of photovoltaic systems. After the installed capacity of photovoltaic system hit a new record in 2021, the installed capacity of small household photovoltaic system in Germany reached 1.6gw, with an average installed capacity of 15kw. It is expected that the installed capacity in this field will increase by another 1.8gw this year.
It is estimated that the number of 10 ~ 15kw household photovoltaic systems installed in 2022 will increase significantly, while the number of 5 ~ 10kW household photovoltaic systems installed will continue to stagnate. As in previous years, the relevance of the German household photovoltaic system market continues to increase in 2022. In 2021, 30% of the installed capacity of household photovoltaic systems in Germany will reach 15kwp; By 2022, this proportion is expected to increase to 36%.
With an installed capacity of 1 ~ 15kw, the household photovoltaic market in Germany is booming. The increase of roof photovoltaic power generation of residential users reveals the impact of heating and traffic electrification. In a recent survey, 500 residential owners were interviewed about the energy consumption of household photovoltaic system. About two-thirds of the respondents said they would first meet the daily power consumption, while almost all other respondents believed that the installation of energy storage system for photovoltaic system is an essential measure. One third of respondents said they would use photovoltaic system for electric heating, while one quarter said they would use photovoltaic system to charge electric vehicles.
From the investment plan of owning photovoltaic system to the importance of owning special charging stations for electric vehicles, we can see the importance of photovoltaic system for charging electric vehicles. 95% of the owners of photovoltaic systems believe that charging electric vehicles is very important. Home users who actively choose to buy photovoltaic systems also pay more attention to charging electric vehicles. The proportion of homeowners without photovoltaic system investment plan fell to 69%. This result confirms that photovoltaic system owners and planners seem to regard electric vehicles as an ideal consumer.
Dr Martin Ammon, managing partner of research firm eupd research, commented that "in the context of the sharp rise in energy prices, clean and cheap roof photovoltaic power generation is becoming more and more important for homeowners, and the investment in photovoltaic systems has also stimulated the purchase of electric vehicles."
