It’s a scam. Unless they can be used to power your personal home batteries and store power for later use they are a scam.
The panels themselves are not really the issue. Its the storage that is the gotcha. The storage is the most expensive part and batteries do have to be replaced; they don’t last forever.
In time I believe the tech will become better just like coal fired plants. Way back when they were very dirty to operate and lost a lot of that coal to “nothing” and created pollution. Today it is amazing how efficient they are to the point of capturing “waste” and converting it for use as fertilizers (read a story here in PA about such a plant).
Or they can take a serious load off the power grid during the heat of the day in the summertime. At night, the power grid is still there. It doesn’t have to provide power 24/7 in order to be useful.
Battery systems are too complex and expensive, and unless you are "off grid", offer no real benefit. Grid tied solar with "net metering" uses the grid as its battery for free. Living in Southern California, with some of the highest electricity rates in the country as well as extremely high insolation, solar makes a lot of sense.
While it may not seem fair for SDG&E to be forced to buy my "apples", it's kinda nice to finally screw them after being on the other side of the screw for decades. I use to average over $300/mo for power. Now when I settle up once a year, they pay me.
