When home energy meets policy: exploring the new trend of balcony photovoltaics in Germany

A series of policies have been released across Germany to make balcony PV even more attractive in 2023. For example: Starting from January 1, 2023, the value-added tax on balcony photovoltaic systems will be reduced from 19% to 0%. Promote balcony photovoltaics nationwide. Additionally, there are an increasing number of subsidy programs and grants available for purchasing plug-in solar systems. Many cities and municipalities will pay a portion of the acquisition cost. The federal states will also launch support programs for balcony power plants in 2023.

Here, we have compiled an alphabetical list of balcony photovoltaic subsidy programs, which mainly cover the balcony photovoltaic subsidy programs provided by various federal states and cities. Due to space limitations, we can only list some major urban policies. If you need to know about other regional policies, please leave a message in the background and we will reply as soon as possible.

The situation in each federal state



Berlin has been promoting the purchase of plug-in solar equipment to finance 14,000 apartments from February 10, 2023. Renters whose main place of residence is in Berlin are eligible to apply (submit before purchasing) and receive up to €500 subsidy. Grants are available for one plug-in solar device per apartment. This program is part of the Solar PLUS program and applications can be submitted to IBB Business Team GmbH.



Balcony photovoltaic systems purchased from November 7, 2022 will receive a unified subsidy of up to 500 euros. Applications will be accepted after purchase and installation. According to the agency, all funding subsidies for landlords have been exhausted, but tenants renting in Mecklenburg-Vorpommern can still submit applications from July 2023.



The government will provide irregular subsidies. The latest subsidy will start on September 5, 2023, funding a total of 10,000 balcony solar systems. The government will provide cost subsidies of up to 50%, with a maximum subsidy of 200 euros per system. It should be noted that in order to qualify for funding, balcony PV power plants must be connected using Wieland plugs. If you are a beneficiary of housing benefit, civil welfare or basic security, you may also receive a subsidy of up to 350 euros.
