On-Grid Systems are solar pv systems that only generate power when the utility power grid is available.
Off-grid solar power Plant is system with battery Bank, this type of power plants also stores DC electricity in batteries bank provided with the system.
Hybrid Solar System or Power Plant is a combination of both above said solar systems.
It is the heart of the solar power plant. Solar panels consists a number of solar cells. We have got around 35 solar cells in one panel. The energy produced by each solar cell is very small, but combining the energy of 35 of them we have got enough energy to charge a 12 volt battery.
It is the energy generating unit, made up of p-type and n-type silicon semiconductor. It’s the heart of solar power plant.
Batteries are used to produce the power back or store the excess energy produced during day, to be supplied during night.
Solar panels produce direct current which is required to be converted into alternating current to be supplied to homes or power grid.
