Battery Storage

Energy Storage for Homes & Businesses

Store Solar Power, Save Money, and Stay in Control — Day or Night

Battery systems are a great solution on their own or paired with solar PV. They store any surplus energy generated during the day for use in the evening — helping you save even more on your energy bills.

In winter, batteries can be charged overnight using Time-of-Use (TOU) tariffs from energy providers, giving you access to cheaper electricity and lower EV charging costs.

Some batteries can even provide backup power during a grid outage, keeping your essential appliances running.

There are two types of batteries:

DC batteries connect between your solar panels and inverter — no permissions required.
AC batteries sit between your meter and the grid and may need approval from the DNO (National Grid).

If you already have solar PV, we can retrofit a battery to your system — whether we installed it or not. We’ll design a setup tailored to your energy usage, budget, and any existing FIT payments.

Thinking About Battery Storage for Your Home or Business?

Whether you’re looking to store excess solar energy, take advantage of cheaper night-time tariffs, or gain backup power during outages, a battery system can give you greater control and long-term savings. From rural homes to busy commercial sites across West Wales, we design battery setups that work around your energy habits, property, and budget — with or without an existing solar PV system.

Our advice is free, honest, and tailored to you.
