The deeming period is an estimate of the years the system will create renewable energy. The maximum deeming period is 15 years after which no further RECs can be created. Five year deeming creates in batches. There is a creation for the first 5 years after installation and then at subsequent 5 year intervals. To claim 15 year deeming the system must be installed by an installer accredited with the Clean Energy Council. (Deeming periods are not applicable for solar water heating/heat pumps).
