Home Battery Storage — Energy Independence for Cardiff Homes
Home battery storage is the single most effective way to maximise the value of your solar panels. Without storage, most Cardiff homes export the majority of their solar generation to the grid at a low rate, then buy it back in the evening at a much higher rate. A home battery reverses this — storing your cheap solar energy and using it when you need it most.
GL Solar supplies and installs home battery storage systems from all leading manufacturers across Cardiff and South Wales. We're brand-agnostic — our recommendations are based entirely on what's best for your home, usage patterns and budget, not on which brand pays us the most commission.
Whether you want a compact 5kWh system for a smaller home or a large 20kWh+ system for maximum independence, we have the right solution. We also install battery systems without solar panels for homeowners who want to take advantage of cheap overnight electricity tariffs.

“GL Solar helped us choose between several battery options and were completely honest about the pros and cons of each. We went with a GivEnergy system and it's been fantastic. We're now using 78% of our solar generation and our bills have dropped by over £900 a year.”
