Solar Potential & Climate Data for Frankfurt
Solar Overview
At 50.11° latitude, Frankfurt receives 1,679 annual sun hours, peaking in June. This latitude (50.11°) results in strong seasonal patterns, with long summer days compensating for shorter winter daylight periods. The moderate solar resource in Frankfurt requires optimization of system design to maximize energy production and economic returns.
Geographic Impact
The coordinates 50.1109°N, 8.6821°E define Frankfurt's position and directly influence its solar energy characteristics. The seasonal sun angle difference of approximately 47° at this latitude makes steeper panel tilts more beneficial compared to lower latitude locations.
Rating Methodology
The "Average" classification reflects Frankfurt's solar resource quality, considering its 1,679 annual sun hours and 12.5°C average ambient temperature. The cooler climate enhances photovoltaic efficiency, with panels potentially exceeding rated output during cold, sunny conditions. These conditions make solar economically viable, especially when electricity costs are high or incentives reduce initial investment.
Understanding the Data
The accompanying chart illustrates monthly solar irradiation patterns for Frankfurt. Summer months (June–August) account for approximately 48% of annual solar irradiation, while winter months contribute around 12%. This pattern influences both the technical design and economic viability of solar energy systems in Frankfurt.
⚠️ Important: Due to the high seasonal concentration of solar production, battery storage systems are particularly valuable in Frankfurt to balance energy availability throughout the year.
