# The Growing Role of Energy Storage in Solar Power
Energy storage plays a crucial role in the future of renewable energy, especially for those considering installing solar panels for your home. States across the U.S. continue to set ambitious energy storage targets, and utilities are making major investments in battery and thermal storage technologies. If all current proposals are approved, utilities will add over 18.5 GW of energy storage capacity in the coming years—a massive increase that will enhance grid reliability and the effectiveness of residential and commercial solar arrays.
## Why Energy Storage Matters for Residential Solar
If you install a solar array for home use, your panels generate electricity only when the sun is shining. Without storage, excess energy produced during the day simply flows back into the grid rather than powering your home at night. Energy storage pairs with solar panels for your home to store that extra electricity, allowing you to use solar energy even when the sun isn’t out. As battery costs continue to fall, more homeowners realize the benefits of adding storage to their systems.
## State Storage Targets and Growing Investments
Several states are leading in energy storage adoption, setting ambitious capacity goals:
– **New York**: 6,000 MW by 2030
– **Massachusetts
