At the heart of any solar photovoltaic system is the solar photovoltaic module which transforms light energy to electricity. A standard module has a number of silicon crystalline or amorphous cells connected in series/parallel configuration to get the required voltage/current. A number of such modules are connected in series/parallel combination to get the required power output. ""® photovoltaic systems use high efficiency modules for the best performance and value for money.
Solar Power Generating Units utilise an array of spv modules which are used to charge a battery through a charge control unit and the batteries drive an inverter which acts as a centralized power generating unit. Capacities range from 0.5 KVA to 5KVA and in MW.
