One panel will produce enough power to keep a large-screen television running, so we’re not talking about a lot of power here. I think the real value is that by making solar so easily and readily available, it levels the playing field a bit. If solar is available easily to the common man, then who needs all the overhead of hiring a firm to do the work for you? An advanced do-it-yourselfer could potentially handle the installation easily, making a nice dent in their electric bill. When alternative forms of energy can be acquired easily and within a reasonable cost, ultimately they become affordable for a much larger part of the population.
Ultimately, our survival as a planet depends on finding alternative sources of energy. Every little step towards that future is something to be cheering on.
