Solar modules are designed to absorb solar energy and to convert it to electricity. Mostare designed with anti-reflective glass front surfaces (“flat plate PV modules”) to captureand retain as much of the solar spectrum as possible. Solar module glass has reflectivityless than water or window glass. The Fresno Airport Solar Project will utilize both flatplate PV modules and PV modules that capture and concentrate sunlight onto a solar cell.In the case of concentrators, all the light that hits the solar modules is focused onto a smaller area within the solar module, and the only reflected light is from heat.
