About South Thames Solar

At South Thames Solar, we provide efficient, affordable solar solutions for homeowners and businesses across Surrey and South West London. With energy costs rising, there has never been a better time to reduce your reliance on the grid. We supply, install and maintain grid-tied and hybrid systems.

While every property is different, a bespoke solar PV system can potentially reduce your electricity bills by up to 70 per cent, depending on your generation and usage.

We can pair your solar panels with advanced battery storage so you can capture excess energy produced during the day to power your home at night or in winter, ensuring nothing goes to waste.

We provide a specific, honest illustration for every project, estimating your savings based on your lifestyle and property location.

Beyond the immediate financial benefits, solar is a clean, renewable energy source that can significantly boost your property’s value. From initial design to long-term maintenance, our expert team is here to help you maximise your return on investment and achieve true energy security.

South Thames Solar is a sister company to South Thames Roofing, so we can also care for all your roofing needs.
