-   Attend the yearly General Assemblies (or delegate your vote on another member);

-   Pay your membership fee by the set deadline – 31st March*

*For members joining between 1 October and 31 December, membership fees will refer to the following year (as long as the fees are paid with that period).

What does SEYN does with your contributions?

Since we are a non-profit, the membership fees are a small - yet important – component of SEYN’s funding structure as it allows us to cover some operational and fixed costs (i.e., admin, accountancy, subscriptions, and website fees).

In the future, we hope membership fees will also be able to cover our mentoring work and thus provide more support to former participants in developing their renewable energy projects.
