Maximise the value of your main fuse

Battery as a Service

A battery converts the surplus in your grid connection into a source of income. With Battery as a Service, Sunday Power makes this possible with zero risk for the customer — no Capex, Opex, or operational work. Only additional revenue.

With Battery as a Service, you rent out a portion of your land and the surplus capacity in your main grid connection, and receive a fixed share of the revenues in return. You take on no capital risk — only a share of the upside.
