as of late shpps exist in tajikistan with a total installed capacity of over kw but about one third of them units with a total capacity of about kwh are currently not working many shpps in remote rural areas have been built in a makeshift manner without adequate expertise many are poorly designed freeze in the winter lack technical maintenance and become nonoperational after a relatively short period this can be due to the absence of wellestablished or functioning supply chains for shpps which would ensure the broad availability of such systems and better service support for end users
