Solar energy can be harnessed in two basic ways. First, solar thermal technologies utilize sunlight to heat water for domestic uses, warm building spaces, or heat fluids to drive electricity-generating turbines. Second, photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight. Solar technologies generated 3.4% of U.S. …
Solar battery storage technology allows you to use more of the free energy produced by the solar panels to save money and increase independence from the National Grid. Without battery storage for solar, any excess electricity generated from solar panels will go to the grid to help power other homes. That means you wouldn''t be using the full ...
