It seems like science and technology offer new solar solutions almost daily. What used to be prohibitively expensive and not available in all areas is now becoming a common ingredient in new homes and renovation projects and providing abundant options for off-grid living. Similarly, small systems that used to just power the electric gate at the end of the driveway or the lights on the barn can now make a home completely electrically self-sufficient. Plus, now there is a process known as net metering where you can provide power to your home along with excess power that you can sell back to the grid.
