Boost the effectiveness of your solar system and take control of when you use your energy. Battery storage lets you keep the power you generate and spend it when it’s worth the most.
Battery storage gives you more control over how much energy you use and when, by letting you store solar power for use at any time of the day or night.
After surveying and analysing your property, we’ll select and install the best technology for your home from one of our trusted, industry-leading partners: Tesla and Sigenergy.
We only install products we would fit in our own homes — and we back every system with exceptional aftercare.
A battery is what turns solar from a daytime saving into an all-day one — and it keeps the lights on when the street goes dark.
Store your renewable energy to reduce your carbon emissions and your dependence on expensive fossil fuel prices.
Stay online when a power cut hits your area, protecting appliances and avoiding waste from refrigerated food.
Release stored energy during peak times, or sell your excess back to the grid when demand is highest.
Expand your battery system where and when you need to, with seamless integration into your existing setup.
Indicative pricing on our two most popular standalone battery systems. Both work whether or not you already have panels.
Best for: homes wanting reliable backup power and smart energy storage, whether or not solar is already installed.

“Bright Spark gave us confidence from the start. The solar and battery install was seamless and we’re already seeing savings!”
“I was very impressed with this company from start to finish. Their quotation and accompanying project plan was extremely comprehensive, and they answered any questions I had immediately. My panels and battery system (Sigenergy) took two days to fit, and the guys were all very friendly, worked extremely hard and long hours, and left everything very neat and tidy, a real quality installation. All the post installation documentation was provided quickly as promised, they handled all the liaison with the network provider, and helped set up the app. The system is working really well and I would recommend this company wholeheartedly.”
