At a time that suits your business’ needs, we’ll organise a time to install your commercial solar panels. As a leading purveyor of the products we offer, you can have peace of mind that we’ll professionally oversee your project in the construction & engineering sector.

We will install your solar panels to expertly engineered mounts, ensuring longevity from your future proofed investment. Depending on the construction & engineering sector project, we can install roof ground mounts or use a flush variant.

Our expert team recommend that your installation is completed in a south facing direction, so will install the commercial solar panels that way if possible. Failing that, both east and west work with all businesses, including those in engineering & construction.

Battery Storage

We’re a leading purveyor of sustainable, off grid battery storage. We can discuss this with you and business partners in the construction & engineering sector during the initial site visit.

If your construction & engineering business operates at night or requires a constant power source, our battery storage is perfect. It allows you to store excess renewable energy for when you need it. That way, you always have access to a sustainable source of power.

Our battery storage will prove a smart long term option for all businesses in any sector, as you aren’t affected by the rapidly rising costs of conventional electricity supply. Better yet, it can also be much more cost effective than selling energy back to the grid.

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.
