Life changing technology for your home, business and community
What does it look like?
Gwent Energy CIC installed one of the first mains-connected battery storage systems, in Wales.
That was nearly three years ago and it looked like this!
That same capacity of battery storage now looks more like this (and costs half as much).
A cost effective solution
How does it work?
Your solar PV system begins generating and you use this energy while you’re making breakfast, catching up with the news and getting ready for the day. Then you go out.
While you're out
Your solar PV system is still generating but you’re not home to use it. A smart switch recognises this and diverts the energy to your battery system, gradually filling it up with power.
Maybe you'll come home for lunch
You can put the washing machine on now, but as your PV isn’t generating enough to cover your new power demand, the smart switch diverts power from the batteries and into your house to work in harmony with your solar. Your batteries are gradually emptied and your washing machine has finished. You decide to use your computer for a few hours.
The sun is now out in full glory
Now your solar PV system is generating more than you need, so some goes to your computer and the smart switch starts re-filling your batteries with this spare energy.
A few hours later, your family starts coming home and on goes your television, the phones and tablets are put on charge and you’re turning on the stove. The sun goes down, and the lights go on. Power from your solar PV system starts to wind down and now your smart switch wakes up again. It releases energy from your battery system to get you through your evening meal, and offsets the power you need from the national grid.
We’ve installed more than 100kWh of battery storage for over 20 different homeowners and communities. Our monitoring equipment gives us a good idea of how the systems are working for our customers, and the circumstances in which we would recommend them.
If you have a traditional hot-water tank, a much simpler way to store surplus energy from solar PV systems can be to connect it to a diverter switch and immersion heater. This gives you plenty of hot water for when you get home in the evenings. More information on our iBoost page.
