WebWith an impressive 40% reflectance value, Landmark Solaris™ PLATINUM from CertainTeed is a leader in the cool roof industry. Landmark Solaris is a solar-reflective asphalt roof shingle for steep-slope roofs; its advanced color granules reflect the sun’s rays and can reduce a roof’s temperature by as much as 20% in the summer. WebIt's easier to maintain solar panels all in one site, and you'd need fewer larger inverters, rather than dozens of micro-inverters for each roof. So if we're going to build solar panels somewhere, it still might be a better choice to put it somewhere else, then just paint the building roofs white.
