Solar power allows you to protect your business from excessive energy bills in the face of continually rising energy prices. Stay firmly in control of your energy usage with commercial solar panels.

If your commercial solar panels generate excess energy, you can transfer it to the National Grid. Exporting energy via the Smart Export Guarantee can lead to significant financial benefits for your business.

As a renewable and carbon neutral energy source, commercial solar panels can significantly lower your business’ carbon footprint. Making the switch will also signify your commitment to sustainable practices.

With ever growing ecological concerns, ensuring business operations have a minimal environmental impact is more important than ever. Take control of your Corporate Social Responsibility (CSR) with commercial solar panels.

With the ability to generate free, clean energy, your business can be less reliant on energy from the National Grid. Make exceptional savings on energy costs by choosing commercial solar panels.

The cost of installation and the equipment itself can essentially cost nothing for your business. A solar power purchase agreement (PPA) could be the perfect choice for your commercial solar panels.

Protect Your Business

By choosing commercial solar panels and reducing your current operating expenditure, your business immediately has the potential to become more efficient and competitive. You can either use a PPA, an option consisting of free solar for businesses, or you can also use your own capital instead.

Energy bills are typically one of the biggest expenses for any business, so by reducing one of the biggest drains of your company’s finances, your business will instead become more profitable. In turn, the profit can give you a significant advantage over your competitors regarding your operating costs.

How Commercial Solar Panels Work?

Smart Initiatives



How Commercial Solar Panels Work?

Commercial solar panels contain solar cells, mostly made of silicon layers and a semiconductor material made from sand. When light enters the solar cells, the photons are absorbed and cause the electrons to move within the silicon layers. It is the harnessing of these quickly flowing electrons that provide electrical power.

While similar to residential solar panels, commercial solar panels are typically larger and have a flat configuration to allow for an easier installation process. The cost of installing commercial solar panels will depend on the scale and complexity of your project. To find out more, request a quote from us today.

Designed to stimulate business investment, the higher rates of relief available make it the perfect time to switch to solar energy.

Under this initiative, businesses will benefit from capital allowance measures as a strong incentive.

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.

Jack Beach

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.
