Solar is often thought of as a power source for roofs or utility-scale projects, but Hurricane Sandy brought a whole new need. Thousands of people were without power for days at a time, and solar generators were used to provide power to some of those people. Even today, Consolidated Solar, a generator start up, is providing solar generators used in cleanup.
The generators can be used to power tools, laptops, cell phones, and other small devices. This is just another use of solar panels that wasn't financially viable just a few years ago. But as costs fall, there will continue to be new uses and new demands. RSOL and BMW are working together. The fields are diversifying. Some solar out fits run remote telecoms lines. Others start engines in remote locations. We are just at the 1st base of a long game. They are cheap enough I bought a bunch.
