Stellaris, with a valuation of $24.5 million, is raising funds on StartEngine. The company is developing a fully-transparent and smart photovoltaic window. The electricity-generating window, ClearPower, is designed to meet the urgent need of buildings to generate their own green electricity. Stellaris currently holds three patents and is in the pre-revenue stage. James B. Paull founded Stellaris in October 2007. The current crowdfunding campaign has a minimum target of $9,999.89 and a maximum target of $1,069,999.82. The campaign proceeds will be used to continue refining the product for commercial production, develop automated assembly procedures, and manufacture and install the windows.
