What is the embodied carbon of a home PV system?
Any estimates of how much carbon is embodied in all the parts and labour of a home rooftop PV system?
The carbon payback time of a PV system would vary with its embodied carbon content and the carbon emission factor of the electricity grid it is supplanting. The time to offset its embodied carbon could be much longer than the system’s energy payback time, perhaps even longer than the lifetime of the system.
I am worried about PVs made in Asia being used to supplant very low emissions (Hydro and Nuclear) power in Canada, for example.
I would love to see Embodied Carbon ratings made mandatory on all PV panels.
