The products that the OBL brands as its own cannot be modified from the OEM 's version and typically only are purchased, stored and marketed under the OBL 's own name.

A technical or quality agreement should be established between the OBL and OEM to delineate the respective responsibilities for each party, such as the OEM 's obligation to keep all unit production records as well as any related documents (such as quality system documents) for a period of five years after the last product has been manufactured. The OBL should have implemented standard operating procedures for post-marketing surveillance. The OBL also should review the OEM 's essential requirements checklist, test and inspection reports etc..

Consider the two situations:

• Situation I: A distributor buys Solar Keymarked collectors from the manufacturer and sells the collectors under the original name ->
  As the collector still has the original name and type referred to in the Solar Keymark license, the distributors can of course use the existing Solar Keymark.
• Situation II: A "manufacturer" buys Solar Keymarked collectors from the manufacturer and sells the collectors under his own name ->
  As the collector has a new name and type, it is not possible to link it to the original Solar Keymark license. A new Solar Keymark license with the new name/type must be obtained. No testing is required to obtain the OEM Solar Keymark license, only paper work and inspection/visit.
