More landlords and homeowners\u2019 associations are recognizing the potential of rooftop solar systems, while tenants benefit directly from lower electricity costs. Photovoltaic systems in multi family residential buildings provide more affordable electricity, increase property value, and, thanks to improved regulations in 2026, are easier to implement than ever before. This article explains the concept, how the tenant electricity model works, and the key factors to consider during implementation.<\/p>\n<h2 style=\"text-align: left;\"><span class=\"ez-toc-section\" id=\"What_Is_Photovoltaics_for_Multi_Family_Buildings_and_How_Does_It_Work\"><\/span>What Is Photovoltaics for Multi Family Buildings and How Does It Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: left;\">In a multi family residential building, a photovoltaic system is installed on the roof, and the electricity generated is supplied directly to tenants without passing through the public grid. The key advantage is that residents pay less than the standard utility rate, while landlords generate a stable additional source of income.<\/p>\n<h3 style=\"text-align: left;\"><span class=\"ez-toc-section\" id=\"Definition_The_Tenant_Electricity_Model\"><\/span>Definition: The Tenant Electricity Model<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: left;\">Under the tenant electricity model, the landlord or a service provider generates <a href=\"https:\/\/pvprosolar.de\/en\/solar-power\/\">solar power<\/a> on the building\u2019s roof and sells it directly to tenants. The tenant electricity incentive under Germany\u2019s Renewable Energy Sources Act makes this model financially attractive for both landlords and tenants.<\/p>\n<p style=\"text-align: left;\">A shared photovoltaic system typically supplies electricity for common areas such as stairwells, basements, and outdoor lighting, while also providing power to individual apartments if desired. Depending on the setup, battery storage can be added to make solar energy available during the evening or on cloudy days.<\/p>\n<h2 style=\"text-align: left;\"><span class=\"ez-toc-section\" id=\"Why_Is_Solar_Power_Attractive_for_Landlords\"><\/span>Why Is Solar Power Attractive for Landlords?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: left;\">For landlords, solar energy is more than an environmental initiative. It is a sound financial investment with several advantages:<\/p>\n<ul style=\"text-align: left;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\">Tenant electricity incentives provide government payments for each kilowatt hour supplied within the building.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\">Increased property value, as buildings with solar installations often achieve higher sales prices and attract more tenants.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\">Lower electricity costs for shared areas through self generated power.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\">Greater energy security, as rising electricity prices make self consumption increasingly valuable.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\">Stronger market appeal, since lower energy costs are an attractive selling point for prospective tenants, especially in major cities such as Hanover.<\/li>\n<\/ul>\n<p style=\"text-align: left;\">Landlords also contribute to the energy transition and can highlight this commitment as part of their sustainability strategy.<\/p>\n<h2 style=\"text-align: left;\"><span class=\"ez-toc-section\" id=\"How_Does_the_Tenant_Electricity_Model_Work_in_2026\"><\/span>How Does the Tenant Electricity Model Work in 2026?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: left;\">The tenant electricity model has become significantly simpler due to Solar Package I, which took effect in May 2024.

In these cases, balcony solar systems provide a simple alternative.<\/p>\n<p style=\"text-align: left;\">Since 2024, plug in solar devices with capacities up to 800 watts have been easier to install in Germany. Tenants only need to register them with the grid operator and inform the landlord.<\/p>\n<p style=\"text-align: left;\">While a balcony solar system does not replace a shared rooftop installation, it enables tenants to generate part of their own electricity. Typical savings range from \u20ac100 to \u20ac200 annually.
