Capital Solar Project

PPA Project

How Does A PPA Work?


Capital Solar Project

You can’t make a better investment than solar if you have capital available in your business. Opting for commercial solar panels will demonstrate to your customers that your company cares about the environment and is proactively reducing your carbon footprint.

Depending on your company’s energy usage, commercial solar panels make a lot of sense regarding the return on investment, with a typical ROI of between 17% to 25% year on year. Companies with considerable energy usage can benefit from a higher return on investment.

Solar Panel Savings

PPA Project

A solar PPA is a power purchase agreement. This means that your commercial solar panels will be paid for by one of our funders, and Callidus will install them free of charge.

Besides benefitting from taking energy from the solar system at a reduced rate to what you already pay the grid, opting for a solar PPA also means that you can keep your capital for other business projects.

A PPA is a mutual agreement between you, Callidus and our funder. The agreement concerns the exact specification of what would be installed on the roof of your business and over how long. The term of the solar PPA is entirely up to you, and you can be assured that Callidus wholly maintain it throughout its entire lifetime.

How Does A PPA Work?

At the end of the agreed term, your business then becomes the owner of that asset, and it will continue to make additional savings at the same rate. Financial risk is drastically minimised by the fact that none of your business capital is at stake and that you have the option to end the PPA at any time.

Energy is generated on the roof to power inverters within your commercial solar panels, and then the solar electricity is passed via a generation meter. The solar electricity generated through this process will be cheaper than what you would pay the National Grid for.

If excess energy is not used by the business, this is then passed back onto the National Grid and deducted from the generation meter displaying the required kWhs to pay. This means you pay only for what electricity you use and makes financial sense for companies with substantial electricity bills.
