Why are solar panels mounted at an angle?

Tilting solar panels offer several advantages:

1. Increased energy production: Tilting panels optimize the angle at which they receive sunlight, maximizing their energy output. By adjusting the tilt angle according to your location's latitude, you can capture more sunlight throughout the day and throughout the year. This can result in higher energy yields and improved overall solar system performance.

2. Self-cleaning: When solar panels are tilted, rainwater can help naturally clean the surface by washing away dust, dirt, and debris. This self-cleaning mechanism ensures that the panels maintain their efficiency by reducing shading and keeping the surface clean.

3. Snow shedding: In areas with snowy winters, tilting solar panels can help facilitate snow shedding. When panels are tilted, the snow is less likely to accumulate and can slide off the surface, allowing the panels to continue generating electricity once the snow has cleared. This feature is particularly beneficial in regions with heavy snowfall.

4. Cooling effect: Tilting the panels can create a gap between the panels and the mounting surface, allowing for better airflow and cooling. Solar panels perform better at cooler temperatures, so the improved ventilation can help prevent overheating and maintain the panel's efficiency.

It's important to note that the optimal tilt angle for solar panels depends on various factors, including your latitude, the seasonality of sunlight, and the specific solar system design. Consulting with a solar professional or using online solar calculators can help determine the ideal tilt angle for your location and maximize the benefits of tilting solar panels.
