Main components of off grid system

An off grid system consists of, solar panels, charge controller, Batteries and inverter

Main components of on grid system

An on grid system consists of, solar panels,DCDB, inverter, ACDB, Isolator, energy meter, net meter, lightning protection and 3 to 5 earthing protection sytems are required as per KSEB standards

10 major differences between off grid and on grid systems

1, Off grid need batteries to store the energy production. On grid solar production is exported to the grid 

2, When KSEB supply is down On grid system doest not function, Off grid works well during power failiures

3,  On grid does not require any major maintenance, Batteries in the Off grid system need to be replaced in 5 to 8 years

4, On  grid installation requires approval from KSEB, off grid system does not require any

5, On  grid installation produces an yearly average of 4 units per day while off grid solar sytem production for same capacity is 3 units per day

6, On  grid installation produces an yearly average of 4 units per day while off grid solar production for same capacity is 3 units per day

7, On  grid installation doest ensure flawless uninterepted power, off grid soalr system provides  quality power all the time

8, On  grid installation doest ensure flawless uninterepted power, off grid soalr system provides  quality power all the time

9,  Re-locating an on grid plant is a difficult task, while in off grid system it is much easier

10, Increasing the capacity of on grid system is very difficult since your palnt is approved by KSEB for certain capacity, in off grid plant ypu can add panels and batteries according to your inverter capacity
