Solar panels generate the most electricity in the middle of the day - but for most households and plenty of businesses, that's not always when you use the most power. Solar battery storage closes that gap. It stores the electricity your panels generate, but you don't use straight away, so you can draw on it later instead of exporting it to the grid for a lower rate than you'd pay to buy it back.
BS Renewables designs and installs battery storage systems across Pontypool and South Wales, either alongside a new solar installation or retrofitted to an existing solar system.
Your solar panels generate electricity during daylight hours.
Your home or business uses what it needs in real time.
Any surplus charges the battery instead of being exported to the grid.
In the evening, or whenever your panels aren't generating, your battery discharges to power your property.
Only once the battery is depleted does your property draw from the grid.
The result: a much higher proportion of the electricity you generate is actually used by you, rather than sold back at a lower rate than you'd pay to buy it.

Honest advice on whether a battery is worth it for you - we'd rather tell you it isn't than sell you one that won't pay its way.
One team, start to finish - the people surveying, quoting, and installing are all the same company.

Not everyone does - it depends on your usage pattern, existing solar system, and what you're trying to achieve. Battery storage tends to make the most sense if:
You're often out during the day and use most of your electricity in the evening or early morning.
You already have solar panels and are exporting a large proportion of your generation at a low rate.
You want backup power for essential circuits during a power cut (with the right system configuration).
You're on a time-of-use electricity tariff and want to avoid drawing from the grid during expensive peak hours.
Your business has demand charges or wants to reduce peak grid consumption.
If you're not sure whether it stacks up for your property, that's exactly what a proper survey is for - we'll give you a straight answer, not just an upsell.
For commercial premises, battery storage can do more than store solar generation - it can also help manage demand charges and reduce peak grid consumption, depending on your electricity contract and usage profile. This is assessed as part of your commercial site survey.
What's included:
Usage assessment - understanding your consumption pattern and how much a battery could realistically help.
Bespoke system sizing - matched to your solar system (existing or new) and your usage.
Battery and inverter supply, from established manufacturers.
Full installation, carried out by our own accredited team.
Testing and commissioning, including all necessary documentation.
Ongoing support for monitoring queries and servicing.

Cost depends on battery capacity, your existing system (or lack of one), and installation complexity - we provide a free, no-obligation quote based on your specific setup.
In most cases, yes. Whether your current inverter is compatible or a new one is needed depends on your existing setup - this is one of the first things we check during a retrofit survey, so you get an accurate quote rather than a guess.
Most solar batteries carry warranties in the region of 10 years, with a useful life often extending beyond that depending on usage and cycling.
Some battery systems can be configured to provide backup power to specific circuits during a power cut, though this depends on the system and installation - we'll advise on this at survey stage if it's important to you.
No, it's not essential - but if you're exporting a lot of your generation at a low rate, a battery can meaningfully improve how much of your own electricity you actually use.
It can be, particularly where demand charges or time-of-use tariffs are involved - this depends on your usage profile, which we assess during a commercial site survey.
