Dinefwr Electrical & Solar Ltd install solar PV and battery storage systems for homes across Llandeilo, Carmarthenshire, and surrounding areas, helping homeowners reduce electricity costs and make better use of the energy they generate.
Battery storage allows you to store excess solar energy for use later in the day, reduce reliance on grid electricity, and take advantage of smart energy tariffs. Whether installed alongside a new solar system or added to an existing installation, battery storage can significantly improve how your home uses and manages energy.
As an MCS-certified installer, NAPIT and TrustMark accredited contractor, and Octopus Trusted Installer, we provide safe, efficient installations designed around your property and energy use. Whether you are installing solar for the first time, adding battery storage to an existing system, or planning for future EV charging, we provide clear advice and high-quality workmanship you can rely on.
Battery storage can help homeowners:
Battery systems can be designed around your daily usage, helping you get the most value from your solar generation and electricity tariffs.
If you already have solar panels installed, battery storage can often be added to improve system performance and energy independence.
We can assess your existing system and advise on compatibility, system design, and the best options for adding battery storage safely and efficiently.
Battery storage works particularly well with smart energy tariffs, allowing you to store lower-cost electricity during off-peak periods and use it when electricity prices are higher.
As an Octopus Trusted Installer, we can advise on battery systems designed to work effectively with smart tariffs and future energy products.
Choosing the right installer is just as important as choosing the right equipment. As a local, electrician-led renewable installer, we focus on safe system design, high-quality installation, and long-term reliability.
With over 25 years of industry experience, we understand both renewable systems and the electrical infrastructure they connect to.
We are accredited with NAPIT, MCS, and TrustMark, and are proud to be an Octopus Trusted Installer. We are also registered as an OZEV authorised installer for EV charge point installations.
We design each system based on your property, usage patterns, and future plans, rather than using a one-size-fits-all approach.
We install systems from leading solar, battery, and smart energy manufacturers including SolaX, Myenergi, Eleven Energy and other industry-recognised brands.
