How Solar Power System Works ?

Solar power is harnessed using SolarPhotovoltaic (PV) technology that converts sunlight (Solar radiation) intoelectricity by using semiconductors. When the sun hits the semiconductor withinthe PV cell, electrons are freed and bus bars collect the running electronswhich results in electric current. When we place Solar panels connected in acalculated manner in the sunlight, they start producing current and voltage inthe form of Direct current (DC) but in most of the countries in the worldappliances and equipment runs on Alternative current (AC) so we need to connectto all Solar panels to an Inverter which then converts DC into AC for home use.

1.On-grid Solar Power System / Gridinteractive System

> This type of system is used when youwant to reduce your electricity bill , In this type of system you will save theper unit amount multiplied by units generated by Solar system (known as netmetering, involves govt. approvals) > When your house’s electricityconsumption is low and solar generation is high your Solar system will feed theexcess energy into the grid/electricity company. > When your electricityconsumption is high and solar generation is low your Solar system will take theexcess energy from the grid/electricity company and feed into your home.

2. Off-grid Solar Power System / StandaloneSystem

> This system is used whenelectricity/grid is not present or someone required backup to safeguard againstpower cuts. Also, in some cases, if someone wants to generate his own greenenergy! (No govt. involvement is required in this case) > This is a batterybased system, so energy generated from the solar panel is stored in thebatteries which are connected with this system > You can operate some of essentialequipment/appliances directly on this system at the time of grid unavailabilityof no sunlight hours as well

3.Hybrid Solar Power System

> This one is the combination ofoff-grid and on-grid solar system.   Ifthe electricity consumption of your house is lower than the energy generatedfrom Solar system, excess energy will get stored in batteries connected withthis system.   If the house electricityconsumption is greater than Solar energy generation excess requirement will becatered through batteries. If the house electricity consumption is lower thanthe energy generated through Solar panels and batteries are fully charged thanthe excess energy generated goes into the grid/electricity dept.
