Life of the modules
While all the modules manufacturers claim 25 years of life whether it is crystalline or thin film, the main question is what would be the balance capacity after 25 years considering the degradation rate. A good quality and state-of-art hermetically sealed crystalline module has been reported to be working with little degradation even after 25 years which is a bonus for the power plant owner.
The experience at the Solar Energy Centre, New Delhi shows upto 40% degradation in 10 years in the case of thin films. Under such situation, the life of thin film modules is questionable and poses technology risk to the project.
