Services
At Helios Energy we have been providing renewable energy solutions to residential and commercial properties across the South East for over a decade. Based in Surrey, and run by father and son duo Will and Laurence Clemson, we work closely with our customers to design and install renewable energy systems that best suit their needs.
Will Clemson With a degree in mechanical engineering and a project management background, Will has been working in the solar and renewables industry since it began gaining traction in the UK back in 2011. Even prior to this, Will worked in engineering with machinery that manufactured solar PV cells.
MCS stands for the Microgeneration Certification Scheme. It is an industry-led quality assurance scheme which provides proof that your renewable installation has been designed, installed, and commissioned to the highest standard. NAPIT is a leading government-approved and United Kingdom Accreditation Service (UKAS) accredited, membership scheme operator within the building services and fabric sector.
The inverter sends the converted electricity to your fuse box which can then be split depending on your requirements e.g. When there is no sunlight, your solar panels will obviously not be capturing any electricity. This is where your storage battery comes into play. The energy captured during the day goes from your storage battery back into your fuse box to then feed your domestic appliances and electric car charge point as required.
There are two types of solar panels - thermal and photovoltaic (or PV as it is commonly called). Solar PV is what we at Helios Energy specialise in. We install solar panels onto the roof of a property so they can catch the sun's energy and convert it into electricity. Stage 1 - FREE Assessment and Quote A member of our team will visit your property to talk through your requirements and design a solar PV system that best suits your needs.

Very pleased with the work done to reinstall my solar panels following roofing work. The guys worked so hard in over 30 degree heat. Polite and cheerful throughout. Panels working well again. No hesitation in recommending to others.

Lawrence came to help put up several pendant lights and a porch light in our new house and he was very efficient and professional with his work. We look forward to using him again in future for a loft light and outdoor light. We highly recommend his services!

A week or so ago, my solar panels stopped working properly and nothing was registering on my generation meter. I rang Helios and received very prompt attention with a visit from Will to investigate the problem, a swift and reasonable quote which I accepted and the work all completed within days. I was extremely impressed with the firm's speed and attention to detail and would highly recommend them. Current Covid rules on social distancing and mask wearing at this time were fully followed. Excellent work!

Helios repaired damaged garage power supply, upgrading the cabling to accept car charging - I hadn’t even considered this future proofing. The quote was fair, and matched the final invoice. The work was carried out quickly, was very tidy and obviously done with care/pride. Laurence and Will were friendly and knowledgable. I will use Helios again, and wouldn’t hesitate to recommend.

Helios delivered and installed battery, roof panels and car charger for us - they were super helpful and knowledgeable and pleasure to deal with. Install is very neat and Will and Clem really went out of their way to explain how it all fits together - I would thoroughly recommend them :-)

Helios installed sixteen panels on our new roof in October 2015. Throughout the process from design and quotation to installation, which involved liaising with the roofing contractor, Will and Laurence were very professional, accommodating, pleasant to deal with, and their communications were excellent. We have enjoyed, and continue to enjoy, the generation of electricity which reduces our electricity bills hugely, and we get pleasure from 'doing our bit' for the planet. It is also reassuring to know that if we have any queries, being local, Helios are easy to contact and they respond quickly.

Helios installed a Zappi car charger for us and were excellent. They thought through the individual requirements with me and we have exactly what we want. Their follow-up when we had a small problem was fast and effective.
