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 Although the Feed-in-Tariff (FIT) scheme has been discontinued, it has now been replaced by the Smart Export Guarantee (SEG).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.


By making the choice to switch to solar energy, you can easily increase the value of your home or business, reduce the amount you spend on energy and stay in control of how you use it. With Callidus, we offer seamless installations, world leading products and ultimate care and professionalism.
