Dear Sir, It is observed that PVsyst's economic analysis doesn't account for battery life. Since every battery has to be replaced after its lifetime (let say 5 years), so in the life cycle analysis of project (let say for 20 years of life), we need to consider the replacement cost of battery (in this case, battery has to be replaced after every 5 years i.e. 3 times). In next version of PVsyst, please consider to add this feature with salvage value of battery also. Sincerely, Bhushan Kamble, Student, IIT Bombay.
