| A WorldWater & Solar Technologies Company 1077 Chisolm Trail Welcome to ENTECH! ENTECH provides advanced solar energy technology for a variety of applications, ranging from daylighting systems for commercial buildings to solar power arrays for spacecraft.Our patented solar power systems produce electricity from sunlight for applications here on Earth (terrestrial power) and in space (spacecraft power). Our inexpensive Fresnel lenses capture the sunlight, and focus it onto small solar cells, thereby reducing electricity costs compared to conventional flat-plate (planar) solar energy approaches. We have also developed a new daylighting system for illuminating stores, schools, offices, and other buildings with unprecedented performance. ENTECH Stretched Lens Array for
