PV MODULE 
    - PV Module converts Solar Energy into Electricity 
    - Power generation is during daytime only 
    - Long life of more than 30 years 

    MPPT’S 
    - Maximum power point tracking 
    - Regulates currents and voltages to maximum efficiency  
               

    BATTERY 
    - Battery stores electricity 
    - Mainly used during night time 
    - Easily damaged if over discharged, or charge/ discharge rate is too high 
             

    CHARGE CONTROLLER 
    - Charge controller protects battery from over charge and over discharge 
               

    DC-AC INVERTER 
    - Inverter converts DC to AC 
    - Not necessary for DC system 
    - AC systems are more convenient for users, but less efficiency  
    - AC systems are for high voltage and high power systems
