With grid-connected energy storage a relatively new technology, stakeholders are yet to fully understand many of the risks and business opportunities it presents, DNV GL’s Dr Martijn Huibers has said.

The UK’s Solar Trade Association (STA) has refuted claims made in a recent report that a residential solar array in combination with an energy storage system was not “economically viable”, calling it flawed and lacking in detail.

There is no economic benefit from installing energy storage with solar PV in UK homes, a new study has suggested, adding that the cost of battery degradation would cost homeowners £400 (US$518) in the first year.
