GreenTech Solar Technologies offers a range of solar energy solutions, including solar windows, solar balloons, hairy solar panels, thin-film solar panels, floating solar farms, Greentech solar paint, wasted-light solar panels, space-based solar panels, wind power, airborne wind energy, and digital solar biscuits. These products convert sunlight into electricity, ensuring transparency and requiring no new installation. High-altitude solar balloons transport panels above clouds, while hairy panels absorb 96% of solar light, making them affordable and easy to install. Thin-film solar panels are budget-friendly and easy to make, while floating solar farms save land by installing panels on water surfaces. GreenTech Solar Paint is developing to generate energy from the sun by breaking down water into hydrogen and oxygen. Wasted-light solar panels absorb non-visible light, a significant part of the electromagnetic spectrum, and are being developed to address climate issues.
