Solar electric windows

Traditional opaque solar panels use photovoltaic technology , meaning they capture energy in the form of light and use it to generate electricity. Because windows are meant to let light through, windows that act as solar panels need to reconcile letting incoming light through to illuminate a room and also capturing incoming light to use for energy production.

For solar panel windows to impact the solar market, they need to become truly building-integrated and unobtrusive by utiliizing transparent solar panel technology. The only currently installed solar windows are made by Physee, called PowerWindow. They are only installed in one building in the world, a Dutch bank with over square feet of the PowerWindows.

When it comes to solar panel windows that generate power from the glass itself, the technology is much further away. The key to a future with true transparent solar windows may involve nanotechnology. If windows can be designed with quantum dot technology , enough energy may be able to be harnessed from the sun while still letting light through the glass window pane the quantum dots are housed in.

In theory, quantum dots embedded in glass windows would be able to absorb light and re-emit it as infrared light towards solar cells housed at the edges of window panels, which would be used to generate power. Again, this technology is not available yet and may not be for years, but it represents an opportunity to make fully transparent solar panel windows a reality.

One similar solution currently in late-stage development is solar panel blinds. Instead of the actual window producing energy, a company has designed blinds that can be hung either inside or outside of a window that have small solar panels installed along them. The blinds can be set to automatically rotate to follow the sun throughout the day, optimizing energy production and efficiency.

Solar windows are barely beginning to touch the market, and remain highly inefficient and expensive. Generate power alongside valuable crop production. Offset energy consumption, achieve rapid payback. Charging, whether driving or parked. SolarWindow Technologies, Inc.
