TESLA has recently been creating solar roofs, which have also been featured on the TESLA website. Now, solar blinds are becoming a thing too. These are strips of solar panels slanted outward next to a window. Theoretically, it seems to work.
There are a lot more windows than roofs, and so why not take advantage of it? Contrary to what one might think, there are a series of problems. Sides of walls are at a disadvantage compared to roofs, and power generation seems to be low.
The solar windows company says that it can create about 1.5 kWh per day, which comes to about $88 worth of power a year. At the cost of installation of $385, it will take 4-6 years to break even. Though this technology is interesting, we will have to wait and see to examine its effectiveness.
