Legislators in various states are introducing bills to allow for plug-in solar systems, with some facing opposition from utilities citing safety risks. Advocates argue that the small size of these systems means very little energy will flow back onto the grid. Balcony solar bills in several states are on track to pass, with California potentially being a massive market for this technology. Supporters see plug-in solar as a way to save money and move towards a healthier, greener future. The importance of passing portable solar bills in states is highlighted as a way to increase access to solar energy, with the hope of seeing solar panels on balconies across the country.
