it is a Renewable Energy Engineering question

Answer 1

L Solar Module : It is that is an absorb a single photovoltaic punel assembly of connected solare cele They sunlight to generate electricity array of modules are used to supply power to An buildings Battery: It is wed to store the electreical energy Converted by the solar module. Charge controller It is used to manage charging the battery bank, preovent, it from overcharging and control the reate of the current and voltage. Inverter: Its function is to change the variable De current output of the solar modules to AC. Connecting Cables used to connected all the components together and treansferi electricity A system without over discharge - sunlight solar module I + Vac charge controller + D.C load Fusy Inverter 12 to 48 vott Battery AC Lood

IT: A system with overe-discharye same diagream with battery connection as shown Battery bann Discharge jollontano Remaining connection is same) - Hov bro troch The system would have a voltage drop, typically around 0.5v and there would be thermal fluctent ctuations ore chances of internal Cisco) over- short circuitrey during discharging such effects are not seen when there is no over discharging
