PV System Power Production Guarantees
I received a question from a potential customer today about power production guarantees for Photovoltaic (PV) Systems. I realized that I hadn’t covered that issue on my blog, so I thought I would copy the question and response here (revised for clarity). Question: Is there a guarantee on the percentage power output of the proposed photovoltaic system? Answer: The Canadian Solar CS6P-250P modules themselves have a power production warranty that states basically that they will put out a minimum of 97% of rated power at test conditions during the first year and degrade no more than 0.7% per year thereafter through a total of 25 years.
