Solar battery

Exciting new solar battery technologies are becoming more affordable and are revolutionising the way we use energy. Solar energy produced in the day can now be stored in batteries for use in the evenings and overnight.

The development of lithium ion batteries means the system is virtually maintenance free and operates seamlessly in the background.  Batteries can also be hung on an outside wall for convenience.  Rapid cost reduction has now made batteries a realistic environmental and financial investment.

Totnes Energy installed the first Tesla Power Wall in the UK on 30 March 2016.   We then installed one of the first v2 Tesla Powerwall’s in the UK.
