On-Grid Solar Power System
A grid-connected solar system is directly connected to the traditional electric utility grid. The electricity you generate using this system can fed back to the main grid. A solar net meter is installed along with this system to measure the units consumed by you versus what you generated and fed back to the main grid. When an on-grid solar system is producing more power
than the home is consuming, then excess power can be fed into the utility through solar net metering. This system works only when the main grid available hense it does not work when the main grid not available. Off-Grid Solar Power System
An off-grid solar system store the electricity produced by solar panel in batteries and utilize the stored energy by converting it back to AC through the inverter as and when required. Especially in a high power cut or no grid areas, has resulted in increased demand for such systems. The reduction in battery prices over the years has further brought the system cost down. To protect against shortfalls of power when the solar system is under-producing then an electric source is usually added to the system. The power generated by this system can be consumed as the excess power can’t be sold back to the utility or grid department. Hybrid Solar Power System
A Hybrid solar power system is connected to the main utility power grid and also with battery for the backup. The addition of a battery backup enables the load to run even when there is no main grid available or protects against power outages. When solar power production exceeds demand, the excess power can charge the batteries, which store the electricity and when system producing less electricity than the batteries can make up the shortfall. Hybrid solar systems are also connected to the main utility power grid. This enables you to sell units to the grid department when there is excess production from solar panels. These systems are more complex to design and install and therefore more expensive.
