Solar Power Battery – Powerwall!

Tesla unveils a battery to power homes from solar panels

Have just seen this on the news and it could well be something of interest to all those who have solar panels on the roof. It’s certainly new technology that I’m going to watch with a lot of interest. I cut my imported electricity use by more than half since I had my solar panel installation – if I can cut it further then that will be even better!

The Tesla web site has revealed

Powerwall

Energy Storage for a Sustainable Home

Powerwall is a home battery that charges using electricity generated from solar panels, or when utility rates are low, and powers your home in the evening. It also fortifies your home against power outages by providing a backup electricity supply. Automated, compact and simple to install, Powerwall offers independence from the utility grid and the security of an emergency backup.

Lots of questions to ask but this looks like the perfect partner for a home solar panel installation. Most of us are out when the sun is providing us with the best electricity yield and therefore a large part of our solar generation gets exported to the Grid. At night, when the sun has gone we then purchase the electricity back again at higher rates. So imagine the prospect of a device that holds some of this electric back for us to use instead of buying it back when the sun is either in or not brighter enough.

So for now well done to Tesla 🙂
