Quick Answer
Solar panels can work in shaded areas, but their efficiency will be significantly reduced. Shading can decrease the overall output by 30-50% or more, depending on the amount and type of shading. To minimize losses, select a suitable location and consider adding a battery bank.
Choosing a Suitable Location
When setting up solar panels on an RV, it’s essential to select a location that receives minimal shading. Aim for an area with unobstructed sunlight between 9am and 3pm, when the sun is highest in the sky. Avoid placing panels near trees, buildings, or power lines that can create shadows. If possible, position the panels to face true south (within 15°) to maximize sun exposure.
Understanding Shading’s Impact on Efficiency
Shading can significantly impact solar panel efficiency. A 10% shading can decrease output by 3-5%, while 20% shading can reduce it by 10-15%. To give you a better idea, here are some general guidelines: a 30% shading can reduce panel output by 30-50%, while 50% shading can decrease it by 50-70%. Keep in mind that these are general estimates, and actual losses may vary depending on the type of shading and panel design.
Selecting the Right Panels and Inverters
To minimize the impact of shading, consider investing in solar panels with high efficiency ratings (around 20-22%). This will help ensure that your system produces as much energy as possible, even in shaded conditions. Additionally, look for inverters with advanced features like maximum power point tracking (MPPT) and grid tie capabilities. These features can help your system adapt to changing sunlight conditions and optimize energy production.
