SOLAR OFF GRID SYSTEM

OFF GRID SOLAR:

Off-grid systems work independently of the grid but have batteries which can store the solar power generated by the system. The system usually consists of solar panels, battery, charge controller, grid box, inverter, mounting structure and balance of systems. The panels store enough sunlight during the day and use the excess power generated in the night.

WORKING OF OFF GRID SOLAR POWER SYSTEM:

Off-grid solar PV systems work on the basic photovoltaic principle, when solar radiations are incident on the solar panel it generates energy in the form of direct current(DC).
The generated DC energy is fed to the charge controller which regulates the flow of charge and supplies the regulated power to the battery. To supply power during the night or on non-sunny days, batteries play an important role.
On a sunny day when the solar panel operates efficiently and produces enough power to cater for the load and also to charge the battery, excess energy is stored in the battery and is retrieved later when required.
The DC energy from a solar panel or battery is converted into alternating current(AC) energy (as most of the appliances at residential/commercial buildings run on AC supply) with the help of an inverter
This converted AC energy is supplied to the loads connected with the help of the wiring connection.
