Thx. Did not know this.
My parents recently looked into it for their house. Fortunately they asked around. The sales guy painted a picture that was bull on it’s face about only cleaning them a couple times a year and lifetime guarentees.
If you leave a car outside most of the year, your windshield is dusty in a coupls DAYS. The more dust, the less efficiency as light cannot get to the panel. Then the AZ sun bakes them. Seems the ideal place for solar but it isn’t. They fail a LOT. The companies making them go bankrupt regularly so lifetime guarantees arent worth the paper they print them on many times.
If you have a couple to power a well or something, maybe. Relying on it solely is a huge gamble. Using it as an add on or those thinking about $$$ selling back to the grid are usually disappointed when the numbers are crunched.
