Commercial Grid-Connected PV systems
Reliable power supply is critical for business needs, especially factories. In Indian cities and villages, power supply can be erratic and diesel generators for backup power come with hefty fuel costs and can be expensive to maintain, besides being highly polluting.
Our Commercial Grid-Connected PV systems are a green alternative with a capacity of more than 10kWp. They can be easily located on the roofs of factories, commercial businesses, office blocks, shopping centres or retail shops and the power generated can be consumed by loads within the buildings.
We are one of the top-rated companies in the installation of On-Grid/Grid Connected Solar PV Systems with many years of experience in the design and manufacture of Centralized and Distributed Grid-Connected PV Systems. We have executed thousands of residential and commercial projects, ranging from 1kWp to MW scale, around the world across different terrains.
Grid-Tie Solar PV Systems
A grid-connected solar PV system uses solar modules as the power generation source. The power produced is fed into an inverter which changes the DC power output of the solar array to AC power compatible with the regional power grid regulations at the installation site.
The system allows for any on-site loads to be powered by a combination of power generated by the PV system and power drawn from the mains power grid. Excess power generated by the PV system is exported to the power grid.
The major components of a grid-connect PV system are:
• PV array
In addition to these major components are the necessary cables, junction boxes, protection devices, switches, lightning protection and signage.
There are two general types of grid-connected PV systems.
- Centralised or Utility-Scale Grid-tie PV Systems
- Distributed Grid-tie PV Systems
Centralised or Utility-Scale Grid-tie PV Systems
The existing electricity system typically consists of central power stations using a variety of fuel sources such as coal, gas, water (hydro) or diesel that provide power to end users via transmission lines and a distribution system. The power stations directly connect to the transmission/distribution system and power produced by the power stations is consumed by end users at their actual locations like factories, business and residences. A central grid-connected PV system operates in the same way. A large PV array is directly connected to the transmission/distribution system.
Distributed Grid-tie PV Systems
Distributed grid-connected PV systems are connected to the ‘load’ end of the electricity network. They are usually smaller PV systems, ranging from 1kWp to 100kWp.
