Markets for Entech Collimating Skylight (ECS) Products

Entech Solar’s daylighting products can provide the highest return on investment for customers in areas with high global horizontal irradiation (GHI), high electricity prices and maximum incentives (federal, state and/or local). The ECS product is ideally suited to provide daylighting for buildings in the commercial, industrial, institutional, and government sectors. GHI is the energy coming from the sun that includes both direct and diffused radiation. The respective maps below illustrate ideal GHI regions with darker oranges and reds for both the USA as well as globally. These maps provide the amount of the sun’s energy over the year that intercepts a surface area tilted at the local latitude angle. The baseline ECS products have an aperture opening for sunlight to enter that is tilted toward the equator at about the average latitude angle across the USA. Incentives available for energy efficiency/daylighting in different localities in the USA can usually be found at the following excellent website: www.dsireusa.org.
