Off-Grid Solar Systems for Swansea & South Wales
Off Grid Solar PV and battery systems are systems that do NOT require any grid electricity supply for them to operate. They are totally 'Stand Alone' and can be used almost anywhere.
For properties without a National Grid connection — or for owners who simply choose not to rely on one — an off-grid solar system generates, stores and manages all of your own electricity on-site. A. Lloyd Electrical & Solar Limited has designed and installed off-grid solar PV systems across Swansea, the Gower Peninsula and South Wales for over 15 years, backed by 32+ years of electrical contracting experience, full MCS accreditation and NICEIC approval.
What Is an Off-Grid Solar System?
An off-grid system combines solar panels, a battery bank, an inverter/charge controller and, in many cases, a backup generator, to provide a self-contained power supply. Unlike a grid-tied system, there is no connection to the National Grid at all — every watt of electricity you use is generated and stored on-site. This makes off-grid solar a practical solution for rural properties, agricultural buildings, holiday lets and self-build projects across South Wales where a grid connection is unavailable, unreliable, or prohibitively expensive to install.
Is Off-Grid Solar Right for Your Property?
Off-grid systems are a strong fit for:
Rural properties and smallholdings on the Gower Peninsula and across rural Swansea, Neath and Carmarthenshire where grid connection costs are high
Agricultural buildings — barns, stables and outbuildings needing power for lighting, water pumps or equipment
Self-build and renovation projects where a new grid connection would delay the build
Holiday cottages, static caravans and glamping sites across the Gower and wider South Wales coast
Boats and static leisure vehicles requiring a reliable, independent power supply
If you’re unsure whether your property is suitable, our free, no-obligation survey will assess your energy usage, available roof or ground space, and sunlight exposure to confirm the best approach.
How We Design and Install Your Off-Grid System
Every off-grid installation starts with an energy audit — understanding what you need to power, when, and how much backup capacity you need for periods of low sunlight. From there, our MCS-accredited team designs a system specific to your property, covering:
Solar panel array — sized and positioned for maximum year-round generation in South Wales conditions
Battery storage bank — sized to cover your typical daily usage plus a buffer for overcast days
Inverter and charge controller — to manage power flow safely and efficiently
Backup generator (optional) — for extended periods of low generation, reducing the battery bank size needed and lowering upfront cost
Full installation, commissioning and MCS certification — carried out by our own team, with no subcontractors
Single Phase and 3 Phase systems
Examples of use for these Off Grid PV systems would typically be any area that requires an electricity supply but is not in proximity to the National Grid or does NOT want to be connected to the National Grid.
Examples of Off Grid system uses:
- Camping fields
- Remote farm buildings
- Fishing lake areas
- Storage facilities
- Off Grid Homes
Basically we can deliver an electricity supply solution almost anywhere
We have designed, supplied and installed many successful Off Grid power systems. They work fantastically well with the modern sophisticated Solar Panels and battery technologies now available.
Simply contact us to find out what we can design for you.
A system that is Off Grid relies entirely on the solar panel produced electricity. There is no mains connection to the National Grid, they are totally ‘Stand Alone systems’
Electricity that is produced by the solar panels that is not used immediately by the premises is stored in the batteries.
The batteries then become the only source of electrical energy once it is dark and the solar panels are no longer producing electricity.
Key benefits of OFF GRID systems
- Totally energy independent - No Reliance on the National Grid for electricity
- No monthly standing charge payments
- Protection from ever rising energy purchase costs
- No risk of inconvenient power cuts
- Totally renewable energy solution with ZERO Carbon emissions

Off-Grid Solar FAQs
What is an off-grid solar system and how does it work? An off-grid solar system generates and stores its own electricity using solar panels and battery storage, without any connection to the National Grid, ideal for remote properties.
Is my property in Swansea or South Wales suitable for off-grid solar? Off-grid solar suits properties without a grid connection, or owners who choose not to connect. We assess your energy usage, roof space and budget during a free survey to confirm suitability.
Do I need a backup generator with an off-grid solar system? Many off-grid systems include a backup generator for periods of low solar generation, though a well-sized battery bank can reduce or remove the need for one. We’ll advise based on your usage.
How much does an off-grid solar system cost? Off-grid system costs depend on your energy needs, battery capacity and any backup generation required. We provide a free, no-obligation quotation tailored to your property.
What maintenance does an off-grid solar system need? Off-grid systems need periodic checks of panels, batteries and inverters to maintain performance. We offer maintenance visits to keep your system running reliably year-round.
