What are availabilities and uses of solar energy/panels? ( explain as much as you can)

Solar panels can be very useful, an they help reduce the use of other power plants that release pollutants into the air. Solar panels have some cons, as the very good ones that have better cells that can store more energy are more expensive, but it is worth the investment, because a big enough field of panels can power a lot of a things during a power outage.

If anyone else has anything about the availability of solar panels, feel free to add.

Hope this helps :)
