What We Do

Here at Callidus, we strive to make your switch to solar energy as smooth and painless as possible. Our friendly team of professionals will visit your property to undertake a thorough survey before we start the installation process. This will allow us to assess the best direction to install the solar panel system and whether battery storage is required.

The innovative technology of solar panels can still produce solar energy even in cloudy conditions, but battery storage can help optimise your energy usage. Whether you require commercial solar panels, residential solar panels or an off grid solar system, Callidus are here to help.

Whether near to us in Newton Abbot in Devon or based further afield, solar energy is the ideal solution. View our sectors page to explore the many ways solar energy can be utilised, or request a quote with us today.

Solar Energy Returns

Callidus can assist in optimising the way you power your property for customers new to solar energy. Although the Feed-in-Tariff (FIT) scheme has been discontinued, it has now been replaced by the Smart Export Guarantee (SEG). Through this scheme, you can sell any excess solar energy generated back to the grid for financial gain.

By selling your excess solar energy back to a licensed supplier, you can reduce your yearly energy bills and stay in control of how much energy your property uses. To benefit from the SEG, you will need to ensure your system is MCS certified, which we can do for you as an MCS certified installer.

Whether close to us in Newton Abbot, Devon or elsewhere in the UK, Callidus can help you discover the many benefits of solar energy for you and your property. Contact us today if you would like more information on our services or advice on what system is right for you.

Happy Customers

The guys at Callidus were all fantastic. We had lots of questions before we had our solar power system installed, and all our many emails were answered very efficiently. The on site team did a really tidy job, and went through how we would use the system. We were very apprehensive about having an off grid system, and had different companies come to quote for the job. We went with Callidus because of the whole package that they offered, which includes their after sales help. We are very happy with the set up and it fulfils all that we asked for, very happy bunnies.

Maxine Heard

We live off grid in Cumbria and wanted to upgrade our electricity supply. We contacted Callidus and they were very happy to work with us. With excellent two way communication they designed the perfect system for us which is easily expandable if we should need it in the future. They were happy to design the system and supply us the parts for us to install ourselves. They programmed the system and were on the end of the phone to help with installation and getting the system up and running. Their after sales service is excellent. It has improved our quality of life no end.

Fantastic customer service! Such incredibly helpful staff. Can’t rate them highly enough. Highly recommend this company. So helpful and really fast service. I spoke with Chris and Dave at a time when other staff where out and they went above and beyond to help.

Isobel Nancarrow

The entire team at Callidus, from the top to the bottom, are amazing. Knowledge, support, passion to place the customer and their needs at the centre of the process, throughout all phases. Clear explanations with realistic expectations; no over inflated figures to close out a deal. I am so satisfied with their approach that I have already completed an expansion of my system; NOT because it didn’t perform as promised, but in fact we are generating more than expected so have increased the battery storage!!

Marcus Rowe

I have just had an off grid solar system fitted by Steve and his team. It has been a completely stress free experience. Everyone was so professional, helpful and obliging, kind and friendly. I would recommend Callidus to anyone.
