Residential solar power has evolved from a specialized technology into a practical option for many homeowners. Today, solar energy can mean much more than simply installing panels on the roof: homeowners can choose from rooftop photovoltaic systems, battery storage, portable solar generators, folding panels, and smaller independent systems for sheds, workshops, and other outbuildings. These options can help reduce dependence on utility electricity, provide backup power during outages, or offer a measure of energy independence. The right approach depends less on having the biggest possible system than on understanding how much electricity a household needs and what it wants solar power to accomplish. Read more
