With power prices on the rise, more and more homeowners are installing rooftop solar panels. However, some are still hesitant about solar panels, with many wondering if they heat up the roof.
No, solar panels don’t heat up your roof or increase your cooling costs. In fact, solar panels keep your roof cool, reducing the burden on your air conditioner. This was the conclusion of a study by the University of California at San Diego researchers last year.
How then can solar panels help keep your roof cool for long periods of time?
Solar Panel Myths Debunked
First off, solar panels don’t produce heat when they generate electricity. Rather, they absorb solar heat, which, under normal circumstances, would be absorbed by your roof, essentially acting as roof shades.
This makes solar panels a welcome addition to flat roofs, which are commonly used in commercial roofing applications. Due to their lack of elevation, flat roofs tend to absorb heat more quickly and are easily damaged by ultraviolet (UV) rays. But with solar panels doubling as an extra layer of protection, you can extend the lifespan of your flat roof – or any kind of roof for that matter.
Maximizing Solar Panels’ Cooling Capabilities
The study even managed to produce hard evidence of solar panels’ effectiveness in reducing the roof’s temperature. It found that solar panels can reduce the roof temperature by as much as three degrees. Keep in mind, however, that solar panels’ cooling capabilities are dependent on their size; the larger the solar panel, the more heat it can block.
To maximize the cooling effect, we recommend tilting the solar panel upwards. The study also showed that the gap between the roof and the solar panel helped maximize the cooling effect.
If you do decide to install solar panels on your roof, make sure to only hire certified contractors.
