Many people have contacted us recently about a battery offer that they have received in the mail from Solar Service Group. The offer is for an Enphase battery at approximately $5000.

What they don’t tell you is that this is a 1.2kWh battery. So based on the average price of electricity $0.26/kWh each year this battery will only save you around $113 (1.2kW x 365days x $0.26/kWh), so in the expected 10yr life the battery will only save you $1130 when it costs $5000.

This is one of the most expensive battery offers on the market.

We have other batteries available but generally we still believe that it will be a few years before batteries should be purchased based on the financial investment alone.
