How will a solar maintenance service benefit me?

Solar PV is often known as a ‘fit and forget’ technology. Compared to other more complex renewable energy technologies, it will happily continue to perform without maintenance. However, for many people, solar is an investment, and just like your business, your home or other investments, it pays to look after it.

How long would it take you to notice that your panels were under-performing due to dirt or an undetected technical issue? If your panels are under-performing, your investment is under-performing.

We take every step during the install process to ensure that your system is fitted to a high standard. However, to ensure your system performs at its best for the lifetime of your feed-in tariff, it’s worth looking after it. We can provide a solar maintenance service so you can be confident your system is working at its best.

Sadly, we also know from experience that not everyone takes as much care, and we are often approached to fix issues. It’s frustrating to find yourself paying out to fix poor workmanship, which is why we take the time to carefully assess your situation and make sure we provide a maintenance service to suit your specific requirements.

We understand how important it is to balance your triple bottom line, so we take care to provide a service that minimises your expenditure and maximises your return, whilst protecting your environmental asset and green credentials.

Our team have years of experience in installing, maintaining and monitoring solar pv systems and we like to overcome your challenges, so whatever you need, we’ll find a solution. Based in Cornwall, we work across the South West.
