The AEEA obligation applies to everyone who brings solar panels to the Dutch market. Hereby it doesn't matter if your organisation manufactures the panels itself or imports them from outside or within Europe.
ZRN is there for every party which deals with solar energy, located in The Netherlands, and who wants to comply with the legal obligations. Do you comply with this? Then you are able to become a participant of ZRN, regardless the volume that you bring to the market.
