The good news: as described, this method concentrates the solar energy using a series of lenses, increasing the efficiency of each cell. The bad news: this means the panel needs to be pointed at the sun at all times. It can't be a passive panel bolted to a rooftop, it has to constantly track the sun. And no, this is not remotely a new idea -- it's been evaluated, and the difficulty of tracking the sun is why it's not used more often. > A novel ... It is not novel. It is an old idea.
