The Solar Calculator EWZ offers a step-by-step approach to evaluating the performance of solar energy systems. Users can input key parameters such as roof area, orientation, energy consumption, and heating system details, with the option to include a battery. The tool calculates and visualizes the yearly and seasonal energy production in kWp and kWh, providing an in-depth understanding of solar system potential. It also presents daily production and consumption distribution through 24-hour diagrams for a typical day.
Beyond energy insights, the Solarrechner delivers detailed financial analyses, comparing investment costs against returns over 25 years. This enables users to assess the economic feasibility of adopting solar technology. Whether for energy optimization or financial planning, the Solarrechner offers a tool to design and evaluate solar systems effectively.
