Cost Savings
In addition, with a home battery storage system the financial gains can be substantial because it is possible not only to store energy produced at times when tariffs are lower but even to sell surplus electricity back into the grid during peak-rate periods. In addition, being able to sell excess power back into the grid can even earn homeowners extra money in cash incentives. Some programs, such as net metering, refund the cost of any surplus electricity that is generated and fed back to them by a homeowner with a household battery store system. As a result, over time the money saved on bills for energy can completely cancel out the initial cost of installing one's home battery storage systems-so it makes economic sense and indeed will appeal strongly to anybody who thinks about cashing in even years down line.
