Yes, you can put solar panels on a metal roof. In fact, metal roofs are an excellent surface for solar installations due to their durability and long lifespan. Mounting solar panels on a metal roof is relatively straightforward, especially with standing seam roofs, as brackets can be attached without drilling holes, preventing leaks and maintaining the roof's integrity. Additionally, metal roofs reflect heat, improving the efficiency of solar panels in hot climates.

Yes. After mounting solar panels on metal roofs, these panels require periodic cleaning to maintain their efficiency. Dust, dirt, pollen, and bird droppings can accumulate over time, potentially reducing the amount of sunlight that reaches the panels.

The frequency of regular cleaning after installing solar panels on metal roofs depends on the environment and the rate of debris accumulation. It's recommended to clean the panels at least once or twice a year, or more frequently if they are in a dusty or polluted area.

Solar panels on metal roofs typically have a long lifespan, often around 25 to 30 years, before their efficiency drops to about 80% of their original output. Anker's high-quality panels may offer even longer lifespans and better performance over time thanks to superior materials and construction. However, the specific longevity of solar panels can be influenced by factors such as the quality of the panels, the angle of installation, and the environmental conditions they are exposed to.
