The main features of the GP-1500 modules are the high efficiency, wide acceptance angle, compact size, cost effectiveness and the high reliability which is always present in Soltec products. The optical design, based on the well known Cassegrain reflecting telescope, uses mirrors to concentrate sunlight approximately 1500 times over triple-junction cells of the highest efficiency. The SOLTEC GP-1500 modules have 80% more power density than conventional a module, which allows a significant reduction in the Levelized Cost of Energy (LCOE).
