Plug-in solar technology, also known as balcony solar, is gaining momentum in the renewable energy sector with new laws in four states making it easier for households to install solar panels that deliver power directly into a home outlet. Cheaper and easier to install than rooftop solar, plug-in solar systems are seen as a way for renters to cut their electricity bills. Interest in these systems has increased due to spiking energy prices. Supporters believe plug-in solar could help shift U.S. culture towards renewables, with prices expected to drop as the market expands.
