PV Cycle

All PV module producers (manufacturers and importers) based in the EU must comply with Waste Electrical and Electronic Equipment (WEEE) Regulations. CSUN is a member of PV Cycle, an European organisation responsible for WEEE-compliant PV module take-back and recycling. This is not only a benefit for our customers, but also to our environment: The majority of raw materials used in PV modules, especially the main components glass and aluminium, can be recovered to improve resource efficiency and reduce waste.

Owners of photovoltaic systems with CSUN modules can dispose of them free of charge after their product lifetime. Generally, small numbers of modules will be transported to collection points by the module owner. Larger numbers (>40 modules) will be picked up on-site.
