Solar panels are very expensive and can not be used on windows.

  "Solar panels are very expensive" Times are a changing, $1/watt stereotypical 100 watt panel is about 2x4 feet. A window of decent quality , somewhat energy efficient, of 2x4 foot size is about $300. TV's sell for about twice what a comparable surface area window costs. A 50 inch TV has about the same surface area as a 100 watt solar panel. Aquariums cost about the same as windows (2ft by 4 ft front would probably be about a 60 gallon, which is about $300) Another way to put it, is if you're looking at glass, per square inch, the cheapest (aside from picture frames) is solar panels, then windows and fish tanks cost about 3 times as much as solar panels, then TVs cost about six times as much as solar panels, per sq inch. Back on topic you'd be far better off installing perhaps 3x to 10x the square footage of solar panels than installing very expensive windows with this film. At least theoretically you could apply the film to siding, maybe even roofs, and have slightly cooler surfaces.

    > 2x4 foot size is about $300 2 micron thick coating probably costs $0.1 for the same size.
