Welcome to The Solar Institute – Now Proudly Based in Cornwall, UK
At The Solar Institute, our mission is to educate and empower homeowners with the knowledge and tools to make the switch to solar energy. We showcase the many benefits of going solar, from reducing energy bills to increasing property value and connect you with trusted local installers right here in Cornwall UK. Switching to solar isn’t just a smart financial move; it’s a meaningful step toward a greener future. By installing solar panels and modern battery backup systems like Tesla’s Powerwall, you can significantly cut your carbon footprint and reduce reliance on fossil fuels.
​Whether you're curious about potential savings or ready to install a full PV system, we're here to guide you every step of the way.

Residential solar installations in the UK have seen a steady rise, with over a million homes now equipped with solar panels—a clear sign of growing awareness and demand. But what’s driving so many people to make the switch to solar energy?

Why are more people in Cornwall switching to solar? The answer’s simple – to save money, and do their bit for the planet.

At The Solar Institute, based right here in Cornwall, we’ve seen first-hand how solar panels are helping homeowners take control of their energy bills. With energy prices rising and no sign of slowing down, more of our customers are turning to solar as a smart, long-term investment.

Solar panels can save you thousands over their lifetime, and with government schemes like the Smart Export Guarantee (SEG), you can even get paid for any extra electricity your system sends back to the grid. You’re not just cutting costs—you’re generating your own income, all from your roof.
Right now, there’s also 0% VAT on solar panel systems and battery storage, making it more affordable than ever to make the switch. And with flexible payment plans, many of our customers are going solar with nothing to pay upfront.

We don’t just install panels—we design full systems that work for your home and your lifestyle. From rooftop solar arrays to battery backups like the Tesla Powerwall, we tailor every job to make sure you get the most out of your investment.
It’s not just about the savings. Solar is a clean, renewable energy source that reduces your carbon footprint and helps protect the environment we love here in Cornwall. For many of our customers, that’s just as important as the financial benefits.

And as a local company, we’re proud to be part of a growing green economy. The UK solar industry is creating jobs, building skills, and driving real change—and we’re excited to be part of that, right here in our community.
