As the demand and prices of electricity keep rising, the world looks at renewable energy sources for its power needs. In recent years, solar energy has become a popular renewable energy source because of its falling costs and improving efficiencies.

A solar system is a setup that generates electricity by utilizing the solar energy system. A typical solar system consists of solar panels (which absorb sunlight), an inverter (which converts DC into AC), mounting structure (that hold the panels in place), batteries (to store the extra power generated), a grid box and balance of systems (wires, nuts etc.).

A solar system with battery storage and a backup is called an off-grid solar system that generates electricity after a power cut or during the night hours.  It has four major components, solar panels, inverter, battery and balancing of system. This solar system is more popular and comes with a power backup and it works independently of the grid.

They are solar PV system which are not connected to the national grid.

• Completely independent from the grid
• Also called Stand-Alone PV systems

Energy can be Consumed at same time of production or stored in batteries.
