Do Solar Panels Heat or Cool Your Roof?

Do solar panels help insulate your roof

If you live in a warmer weather city, such as Murrieta, CA, it is very likely that your HVAC system is one of the biggest energy consumers in your home. Solar panels in these climates make a great deal of sense, not just because they have a greater solar energy potential, but also because they seem to help keep your home cooler.

Research shows that solar panels don’t just help power your air conditioner in the sweltering summer days – they may also contribute to your AC system’s work themselves. In this article, we discuss whether solar panels can help keep your roof and home cooler and help you save some money on your energy bills. Read on.

Do solar panels help insulate your roof?

According to a study conducted at UC San Diego Jacobs School of Engineering, rooftop solar panels don’t just produce electricity free from emissions, but they also help cool down the roofs of buildings on which they are installed. The researchers found that solar panels helped reduce the heat that reaches the roof by a staggering 38%, keeping the roof about 5 degrees cooler than those parts of the roof that are exposed to direct sunlight.

The findings of this study indicate that having solar panels may also lower your cooling costs, which is another perk of going solar, especially if you live in a hot climate. Solar panels on your roof help shade it and reduce the temperatures in the rooms located under the roof. Roof-mounted panels are also installed with a gap of several inches between the roof and the panel, which permits airflow and helps keep both the roof and the panels cooler. Essentially, having solar panels may reduce the need for using your AC during hot summer days, as well as heating during cold winter nights.

On the contrary, solar panels help keep your roof and home cooler, as previously discussed. Exactly how much benefit you get from your solar panels in terms of shading will depend on a number of factors, including: 1) the type of roof you have, 2) whether you have an attic or other room placed directly beneath the roof, as well as 3) the level of insulation and ventilation of your attic.

The type of roof can influence the efficiency of your solar panels at cooling down your home. Most roofs in the U.S. are made from asphalt shingles which can get blisteringly hot during summer. Other types of materials, such as clay and metal also get hot in the sun. To get a substantial temperature reduction, a roof needs to be designed to keep your home cool. Nevertheless, solar panels can help with this a bit.

Overall, there’s little doubt that solar panels can help keep your home cooler. Exactly how much will depend on your specific situation. Although the cooling benefit of going solar is likely to be minor, it definitely doesn’t hurt. What’s more, solar panels also have the additional benefit of helping your roof last longer. Finally, this cooling potential of solar panels is another reason to go with conventional panels instead of solar shingles, which are installed directly onto the roof, without the gap that may aid cooling.
