Battery barrier to off-grid solar could fall![]() Researchers are working toward more efficient energy storage for solar systems. Two big barriers stand in the way of everyday folks doing off-grid solar, meaning a completely independent solar system. First, in order to qualify for what are often substantial rebates from utility companies, you have to install a grid-tied system. And the reality is that most people cannot afford to install a solar system without these utility rebates. Second, the battery systems used for back-up on a off-grid solar system are expensive and inefficient. Add a comment |
