Solar Panel and Battery Storage Installers in Swansea and South Wales

Solar panel systems in South Wales typically range from £5,000 to £12,000 depending on system size, battery storage and property type. Most households see a payback period of 7 to 10 years, with annual savings of £700 to £1,700 depending on usage and roof orientation.

Yes. Through the Smart Export Guarantee (SEG), energy suppliers are required to pay you for any surplus electricity you export back to the grid. The rate varies by supplier. Adding battery storage means you use more of your own electricity first — maximising your savings before exporting any excess.

Solar power works by converting sunlight into electricity using solar panels, typically installed on your roof. Each panel is made up of photovoltaic (PV) cells that absorb sunlight and generate direct current (DC) electricity. This DC electricity then passes through an inverter, which converts it into alternating current (AC), the type of electricity used to power your home or business. At Ulex Energy Solutions, we design and install solar systems that maximise the available space on your property to obtain the best payback period. Excess energy generated during the day can be stored in a solar battery or sent back to the grid, depending on your system setup.

Solar panels are suitable for most UK homes, particularly if your roof receives good sunlight and is in sound condition. South-facing roofs are ideal, but east- and west-facing properties can still generate strong returns. Your electricity usage also plays a key role — households that use more power during the day or have higher overall consumption typically see greater savings. Installing solar panels can significantly reduce energy bills, protect you from rising electricity prices and lower your carbon footprint. Adding battery storage allows you to store excess energy for use in the evening, increasing self-sufficiency and maximising financial returns. The best way to determine suitability is through a professional assessment that evaluates your roof, energy usage and projected savings.

Most residential solar panel installations are completed within two days. The exact timeframe depends on the size of the system, roof type, access requirements and whether battery storage is included. Smaller systems on straightforward roofs can often be installed in a single day, while larger or more complex projects may take slightly longer. Before installation, there is typically a short preparation period for system design, approvals and scaffolding. Once installed, the system is tested, commissioned and registered, allowing you to start generating clean electricity immediately.

A home battery stores the excess solar energy your panels generate during the day. Instead of sending that energy back to the grid, it’s saved for later use when the sun goes down or during a power outage. The battery automatically powers your home when solar isn’t available, helping you use more of your own energy and reduce your reliance on the grid. At Ulex Energy Solutions, we install home batteries that are built for performance, giving you greater control over your energy and long-term savings.

Solar panels can significantly reduce your electricity bills, with many South Wales households cutting grid usage by 40–70% depending on system size, roof orientation and energy consumption patterns. The more electricity you use during the day, the greater the savings, as you rely less on imported power. Adding battery storage can increase bill reductions further by storing excess daytime generation for use in the evening. In addition, any unused electricity can be exported to the grid through schemes such as the Smart Export Guarantee, providing an additional financial return. A tailored assessment will provide accurate projections based on your property and usage profile.

Yes, solar panels continue to generate electricity on cloudy days. They operate using daylight rather than direct sunshine, so even in typical British weather conditions they will still produce energy. Output is lower compared to bright, sunny days, but modern high-efficiency panels are designed to perform well in diffuse light. Across the year, solar systems in the UK generate the majority of their annual production between spring and early autumn, with reduced output during winter months. When combined with battery storage, excess energy produced on brighter days can be stored and used later, helping to maintain consistent savings throughout the year.

Yes, battery storage can usually be retrofitted to an existing solar panel system. Many modern batteries are designed to integrate with current installations, allowing you to store excess electricity generated during the day for use in the evening or during peak tariff periods. The suitability depends on your existing inverter type, system configuration and available space. In some cases, a compatible hybrid inverter may be required. A professional assessment will confirm compatibility and outline the most efficient upgrade option for your property.

Solar panels require very little maintenance. They have no moving parts and are designed to withstand typical UK weather conditions, including rain, wind and frost. In most cases, natural rainfall is sufficient to keep panels clean and operating efficiently. It’s advisable to have the system visually inspected periodically and monitored to ensure it is performing as expected. An occasional professional check can confirm that wiring, mounting and inverter components remain in good condition. With minimal upkeep, quality solar panels can continue generating electricity efficiently for 25 years or more.

Yes, we install solar panel and battery storage systems for both residential and commercial properties. We design and deliver tailored solutions for offices, warehouses, retail units, agricultural buildings and other commercial premises, ensuring each system aligns with operational energy demands and available roof or ground space. Commercial solar installations can significantly reduce operating costs, improve energy security and support corporate sustainability objectives. A detailed site assessment allows us to provide accurate generation forecasts, financial projections and a clear return on investment for your business.
