Generally, they can be a blight on the landscape. Big solar arrays covering the ground. In germany, the farmers ha e found it is more profitable to farm the sun than to farm the land so you see fields of panels. I like them on rooftops, but I have been resisting putting them out in the front yard.
But, they do generate a lot of power. Which can be fed into the grid when they don't want and then the grid can supply energy to me at night when I do want it. Ok, if I had a bank of batteries and an inverter, I could be completely self sufficient, but that costs more. Current regulations her require the power company to buy power from me at the same rate that they sell it to me.
Solar panels break. Generally they are made of glass. Or blow away. And age. So solar power is probably not as permanent as coal fired power plants. They also get dirty. Some maintenance required.
