Our Services

Residential Solar

South Thames Solar specialises in bespoke solar PV installations for home. We can provide panels for all types of roofs, including traditional pitched roofs and flat-roof extensions. We offer versatile mounting systems, including sleek in-roof designs that sit flush with your tiles and traditional on-roof setups.

Our goal is to maximise your self-consumption and drastically reduce your reliance on the grid. Every system is custom-designed to suit the aesthetics of your property and your family’s specific energy needs. This will ensure that you benefit from clean, renewable power and lower utility bills for decades to come.

Commercial Solar

We provide high-performance solar solutions for all commercial and industrial sites. Our team understands that businesses face unique energy demands. Our solar energy company can manage the entire process from initial site specification to large-scale installation.

Our commercial arrays are designed to minimise technical complications and maximise ROI. This helps companies reduce operational costs and meet sustainability targets.

By using high-efficiency panels and expert inverter sizing, we ensure your business remains resilient against rising energy prices while significantly improving your corporate carbon footprint through reliable, large-scale renewable generation.

Battery Storage

To get the most out of your solar investment, South Thames Solar offers advanced battery storage solutions that capture excess energy generated during the day. Rather than exporting surplus power back to the grid for a minimal return, you can store it for use in the evenings or during peak times.

Our systems are modular and adaptable, meaning that they can cater to both new installations and retrofits for existing solar setups. You can gain full control over your energy usage, increasing your independence and ensuring your home or business remains powered even when the sun goes down.

Solar Maintenance

A solar PV system is a long-term investment. Our comprehensive maintenance services ensure it continues to perform at peak efficiency.

Factors like dirt, debris, and environmental wear can cause technical faults in your solar panels or reduce their performance. South Thames Solar provides professional system health checks, electrical testing, and specialist cleaning to protect your equipment.

From monitoring inverter health to ensuring all mounting and wiring remain secure, our expert team identifies and resolves potential issues before they become costly repairs, ensuring your transition to clean energy remains seamless, safe, and highly productive.
