Some homeowners are apprehensive about buying solar panels because of the fear of heating up their roofs. It is no secret that a hot roof can make the rooms below toasty. Although good air conditioning is the answer to consistent comfort, eco-friendly individuals are conscious of using too much electricity on HVAC. Yet, you really shouldn’t be concerned about this.
Solar Panels Minimize Heat Transfer
Rooftop photovoltaic (PV) panels provide shade, keeping the materials underneath them from being directly exposed to the infrared radiation from the sun. While PV modules do transmit some of the solar heat they catch to roofing materials, the transfer of energy is minimal. Solar panels are raised up off the roof surfaces, allowing just a fraction of the infrared light to make it into the house.
Roofing Materials Radiate Heat Solar Panels Generate
Solar panels do generate heat themselves. Many factors affect heat generation in PV modules for they can’t convert all of the light they collect into electricity.
Also, the regions not covered by solar cells absorb sunlight, which then contributes to the heating of the panels. Fortunately, most, if not all, roofing materials reflect a portion of the heat they absorb. As a result, roofs do not become hotter with solar panels.
Solar Panels Can Reduce Heat Island Effect
The main culprits for the urban heat island effect are hardscapes, landscape areas not covered by vegetation. PV panels can actually make a roof slightly cooler, which helps lower outside air temperatures, much like how solar attic fans reduce heat and humidity indoors.
Moreover, a rooftop solar system produces clean energy. It helps reduce the demand for coal, a fossil fuel that emits climate-changing emissions when burned.
