Improve PV-diesel operating management system considering sun availability time

This paper presents a hybrid photovoltaic (PV)-diesel management system performance analysis considering weather conditions. The is designed to operate based on charging current, battery capacity, and loading current. During current decreased but the capacity high, PV remains supplied for low medium When lowered in middle, still supplies However, when decreases voltage below 22.3 volts, supply instantly switches diesel generator. charge calculated by subtracting from load A real-time clock implemented as timer guarantee that there no repetitive switching throughout night panel missing. works automatically through microcontroller control during day 9 hours. improvement has been obtained overcome problem of repeated processes limiting transfer process back sunlight not available.
