Solar Panels

South Thames Roofing is a premier provider of end-to-end renewable energy solutions, dedicated to powering the future of residential and commercial properties. We specialise in the design, installation, and maintenance of high-performance solar PV systems. Our reputation is built on a foundation of expert advice, premium-tier products, and professional installations. All our work is delivered at highly competitive prices.

Our company understands that every property is unique. That is why we design and fit bespoke solar panel systems tailored to your needs. We offer unparalleled expertise in roof integrity.

We can fit an in-roof system for your home or a complex commercial array, and our in-house team ensures your solar PV installation is structurally sound and aesthetically pleasing.

Our commitment to you extends beyond the installation. We can provide insurance-protected guarantees and dependable after-sales support, and the local expertise and high-level customer service necessary to reduce your carbon footprint and secure long-term energy independence.

Our services

  • Residential solar panels We supply and fit solar panels for all types of pitched and flat residential roofs. Options are in-roof designs that sit flush with your roof, replacing a section of tiles or on-roof setups, where the system is mounted to a racking system and then attached to the roof.

  • Commercial solar panels We can help with large-scale commercial PV projects from site design to commissioning. Our commercial arrays focus on maximising ROI and operational resilience. We help businesses meet their sustainability targets while also shielding them from volatile energy markets.
  • Battery storage Our modular battery solutions capture any surplus energy that is produced during the day. This allows you to power your property at night or during peak periods, significantly increasing your energy autonomy.
  • Solar maintenance Our team can also maintain, clean and test your panels so that they stay in optimal condition. We resolve performance drops caused by debris or wear, so your system remains safe and productive for decades.

The benefits of switching to solar

Investing in solar energy offers both immediate money saving and long-term asset growth. By generating your own power, you can reduce electricity bills by up to 70 per cent, providing a robust shield against rising global energy costs. Through the Smart Export Guarantee (SEG), you can even turn a profit by selling surplus energy back to the grid.

Solar installations will boost the value and market appeal of your property. As a clean, renewable resource with zero emissions, it is the most effective way to lower your carbon footprint. When paired with our advanced battery storage and EPS switches, you gain true energy security, keeping your lights on even during local grid outages.

With 25-year manufacturer guarantees and our expert in-house maintenance, your transition to green energy is a secure, durable, and highly profitable investment.

Our proven process

We handle the entire journey in-house. It begins with a consultation and design phase, which includes a technical survey and an ROI illustration. We then manage all permissions and grid applications (DNO) to ensure full compliance.

Finally, our team performs the installation and commissioning, conducting rigorous safety tests to ensure peak efficiency from day one.

Frequently Asked Questions

While savings vary based on usage, a bespoke system can reduce your bills by up to 70 per cent. We provide an honest, specific illustration for every project to estimate your personal ROI.

Unlike many firms, we use a dedicated in-house team rather than subcontractors. We can ensure genuine roofing experts protect your roof’s structural integrity.

Standard systems shut down during outages for safety. However, if you opt for our battery storage with an EPS (Emergency Power Supply) switch, your system can operate in ‘island mode’ to keep your property powered.

No. Solar panels operate on daylight and not just direct sunlight. Production is highest on clear days, but your panels will continue to generate significant power during cloudy weather and throughout the winter months.

Yes. We offer battery storage retrofits and maintenance services for existing systems. We can work on all systems, regardless of who originally installed them.
