Quick Answer
Solar panels can be installed in shaded areas, but they require specific considerations and equipment. Some solar panel brands offer shaded area solutions, although they may not be as efficient as those installed in full sun.
Choosing the Right Solar Panels for Shaded Areas
When selecting solar panels for shaded areas, it’s essential to look for high-efficiency panels with a low temperature coefficient. This coefficient measures how much the panel’s efficiency decreases with temperature. Look for panels with a temperature coefficient of -0.3% or lower per degree Celsius. For example, the SunPower X-Series panels have a temperature coefficient of -0.14% per degree Celsius.
Optimizing Panel Orientation and Angle
In shaded areas, it’s crucial to optimize the panel’s orientation and angle to maximize energy production. A south-facing panel is ideal, but if that’s not possible, east- or west-facing panels can still produce energy. The ideal angle for solar panels in shaded areas is slightly higher than in full sun, typically between 30° and 40°. This allows the panel to receive more direct sunlight during the winter months when the sun is lower in the sky.
Using Shading Tolerant Inverters
Shading tolerant inverters can help mitigate the impact of shading on solar panel performance. These inverters can detect shading and adjust the panel’s output accordingly. Look for inverters with advanced shading algorithms and high efficiency ratings. For example, the Enphase IQ 7+ inverter has a built-in shading algorithm that can detect shading and adjust the panel’s output to maximize energy production.
