Residential Grid-Connected PV systems
Even today, many Indian cities and most villages do not have reliable power supply. But now we have made it really simple for residences to switch to solar power so that they have an energy source that is dependable, environment friendly and and cost efficient.
We have developed grid-connected PhotoVoltaic (PV) systems ranging from 1 to 5kWp which can be installed on the roofs of houses and community buildings. The power generated by these systems is first consumed by any loads that are operating in the house during the day, with any excess power being exported to the grid.
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:
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 the power produced by the power stations is consumed by end users at their actual location such as 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.
