Kaiser_Antelope_Valley4_small-resized-600Solar roof systems are becoming more popular and affordable as they are being installed across the nation. With benefits such as financial savings, environmental pros, and protection against peak energy rates, its no wonder businesses are interested in installing solar panels on top of their roofs.

Solar works by converting the sun’s energy into direct current electricity, which is then converted by an inverter to alternating current. The current is then sent through a breaker box to enable power to electrical items inside the building. White reflective roof coatings reflect a majority of the sun’s energy away from the building. This allows the solar panels to capture the direct energy from the sun, as well as, the redirected energy from the white reflective roof coatings. Doubling the energy captured by the solar panels in order to create more power and electricity for the building. White reflective roof coatings maximize the use and capacity that the solar panels entail.

It is important to do your homework when selecting a white roof coating for your rooftop because not all white roof coatings have the same reflective capabilities. National Coating offers a range of white reflective roof coatings, some for standard purposes requiring less reflective capabilities and others (AcryShield A179 and A590) that can reflect up to 92% of the sun’s energy that hits the rooftop. A coating that can reflect that much of the sun’s energy is sure to maximize the energy the solar panels capture and at the same time, lower energy cooling costs inside the building because only 8% of the sun’s energy, aka heat is being absorbed into the rooftop.   

Cool Roof The Cool Roof Rating Council (CRRC) is an excellent source for trustworthy and reliable solar reflectance and thermal emittance values. The CRRC tests numerous roofing products to provide accurate data showing the different levels of reflectivity and emittance values these cool roof products will deliver once installed on your rooftop. National Coatings has multiple white reflective roof coatings and cool roof systems that have been evaluated by the CRRC for initial and 3-year aged ratings – check them out here.
