SMART PHOTOVOLTAIC WINDOWS

Windows that produce power and control solar heat gain

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 BIPV window 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 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 has an electrical output comparable to a high-efficiency conventional module, all while maintaining transparency. Importantly, it achieves this at an affordable cost.

Because ClearPower has two sources of cost savings - PV electricity and AC load reduction - it has a financial return meeting building owners' hurdle rates.
