What are the conditions to receive green certificates for solar panels?
The type of technology, the date of commissioning (AREI inspection), and the maximum theoretical power (kWe or kWp) determine the installation's eligibility rate and set it for the entire period it is eligible for GSCs.
All information on this is available at: Brugel - Mechanisme van de GSC
Can I sell the green certificates to Elia?
Green certificates are sold to Elia once a year. In this case, the seller communicates its decision to irrevocably use the buy-back agreement system to BRUGEL no later than 30 April of the current year. For this purpose, the appropriate sales form must be completed and sent to BRUGEL.
