Financial Benefit

Renewable Obligation Certificates (ROCs) are green certificates issued to operators of accredited renewable generating stations for the renewable electricity they generate. The scheme is guaranteed for 20 years from the commissioning date of your system making it an extremely attractive option both environmentally and financially. This tariff is index-linked to RPI , so once the capital cost of your PV system is paid, all other payback is tax free income.

In Northern Ireland you will receive 4 ROC's for every kWh you generate with systems up to 50kW. With systems of 50kW - 5MW you would receive 2 ROC's.
