Basierend auf Ihrem Standort kann unser Solarrechner bereits einschätzen, ob sich eine oder mehrere Dachflächen Ihrer Immobilie für eine Solaranlage eignen. Compatibility with a photovoltaic system is primarily determined by solar radiation, roof orientation, inclination, shading, and roof size.
Solar systems combined with high self-consumption often pay for themselves after 15 to 20 years. Our Solar Calculator analyzes the profitability of a PV system for you. If the roof is suitable for a photovoltaic system, the question often arises: Is the investment worth it? From a purely ecological point of view, this question can always be answered with a yes. From an economic point of view, the costs (acquisition costs, operating costs), the subsidy contributions, the local electricity prices, the local feed-in tariffs, self-consumption etc., are decisive. Our Solar Calculator calculates the amortization period and shows you neutrally whether the investment is worthwhile.
The digital solar calculator from Houzy analyses the solar potential as well as the costs of a photovoltaic system with just a few entries - completely free of charge and without obligation. The analysis is based on all relevant criteria of a solar analysis and shows you the investment costs, operating costs, subsidies, tax savings, feed-in tariffs, etc. in detail. In just 2 minutes and after a few clicks, the solar calculator is ready and you can see all the relevant information about the photovoltaic system in an overview. The results are completely neutral - Houzy is an independent platform and does not pursue any third-party interests.
To find out whether your house is suitable for a photovoltaic system, we need the address. This allows us to obtain relevant information from publicly accessible databases and directories, such as the geographical location, roof area or roof orientation. Some key data about the house and your energy requirements help us to fine-tune the calculations. Afterwards, you will immediately receive online access to your digital solar analysis on Houzy by email.
Houzy is a start-up and finances itself by brokering third-party services and through advertising partnerships with national and regional partners. However, you as a user always decide for yourself when you want to share which data with whom, and thus always retain data sovereignty. The use of our solar calculator and the entire homeowner platform is permanently free of charge for you. However, if required, you can request free quotes for the installation of a photovoltaic system from one of our recommended tradesmen in your region.
