About
Stellaris is an award-winning building energy technology company. Since 2005 we have been developing products to empower buildings to achieve zero net energy and even net-positive energy. Its extraordinary ClearPower solar window technology produces power comparable to the best PV modules and controls solar heat gain, all while maintaining transparency and views.
With its high power-density and PV efficiency, ClearPower solar windows uniquely can produce enough electricity in windows to make a serious contribution to a building's electrical loads.

Net Positive Energy Insulated Glass Units
ClearPower is a system of dynamic micro lenses integrated in the interior of an insulated glass unit (IGU). Because of its optics and high-efficiency PV, it produces 4 to 5 times the power of other "clear" BIPV windows. The lenses are switchable on demand between two states:
-
Full PV power, while maintaining functional visibility
-
Partial PV power (35% to 40%), with full-range visibility
Because ClearPower has two sources of cost savings - PV electricity and AC load reduction - it has a financial return meeting building owners' hurdle rates.

Net Positive Energy Insulated Glass Units
ClearPower is a system of mini photovoltaic cells embedded in a pane or lite of an insulated glass unit (IGU). Because of its optics and high-efficiency PV, it produces 4 to 5 times the power of other "clear" BIPV windows.
ClearPower solar power windows have an electrical output comparable to a high-efficiency conventional module, all while maintaining transparency. Importantly, it achieves this at an affordable cost.
