Battery-based energy storage is an important component of an increasingly secure, reliable, low carbon, and cost-effective electricity future. Due to this reason and several more mentioned here, the state of California has begun to offer solar rebates for businesses that invest in effective renewable energy. Energy storage has the potential to substantially reduce high utility demand charges, to help integrate deeper penetrations of renewable energy onto electricity grids large and small, accelerate the adoption of other distributed energy resources by enabling customer independence, and, perhaps most importantly, deliver efficient, low-cost, fundamental electricity-grid services to society at large. Additionally, energy storage allows you to make use of all of your solar photovoltaic (PV) capacity. By coupling your PV system with energy storage, you can use your stored solar power at night or on cloudy days instead of drawing from the grid.
