The purpose of solar battery storage companies is to provide a matching energy storage solution for use with existing solar power systems. This type of company has as its main business providing a complete battery storage unit, from design and material trade to construction. It will store the electricity generated by solar panels so that this power can be used at any time. The technical features of such systems include large-capacity lithium-ion batteries, intelligent energy management software, and efficient power conversion electronics. The systems work to hold onto electricity for longer time periods and maintain a reliable power supply during peak demand times or when sunlight disappears. Dissemination by industry of solar battery storage technology spans residential use, commercial applications, and even utility scale projects. When the grid goes out for long periods people can still get to work with remaining batteries in their house so they don't need such a large base load on peak times from redundant power plants, not to mention the rewards of a greatly greener environment.
