PROJECTS BASED ON TYPE OF CONNECTION
Systems that feed electricity directly into the public grid, often selling excess power back to the utility.
By Grid Connection
This describes how solar energy systems connect to the power grid: On-Grid (Grid-Connected): Systems that feed electricity directly into the public grid, often selling excess power back to the utility. Off-Grid (Standalone): Systems that operate independently of the grid, typically requiring battery storage. Hybrid Systems: Systems that combine grid connectivity with battery storage, offering both energy independence and grid reliability.
Key Features and Benefits
Solar Panels (PV Modules)
Capture sunlight and generate electricity.
Inverter
Converts DC electricity to AC electricity.
Mounting System
Secures the panels to the roof.
Batteries (for off-grid systems)
Store excess electricity.
Charge Controller (for off-grid systems)
Regulates the power flow to and from the batteries.
How it Works
- Sunlight Absorption : Solar panels are made of semiconductor materials that capture sunlight.
- Electricity Generation: When sunlight hits the panels, it generates direct current (DC) electricity.
- Inversion: A solar inverter then converts this DC electricity into alternating current (AC) electricity, which is the type used in homes.
- Power Usage/Storage : On-Grid Systems: The electricity is used in the home, with any excess power supplied to the public grid, potentially earning the homeowner credits via net metering.
- Off-Grid Systems: Excess power is stored in batteries for use at night or during cloudy days, allowing the system to function independently of the grid
Grid Tied Roof Top Solar Power Plant
A program of “Ministry of New Renewable Energy (MNRE)”, Government of India, in cooperation with state electricity board for import and export of electricity. We are capable of installing ‘On Grid roof top solar power plants’ with capacities up to 1 MW. In grid connected rooftop or small SPV system, the DC power generated from SPV panel is converted to AC power using power conditioning unit and is fed to the grid either of 33 kV/11 kV three phase lines or of 440V/220V three/single phase line depending on the local technical and legal requirements. These systems generate power during the day time which is utilized by powering captive loads and feed excess power to the grid. In case, when power generated is not sufficient, the captive loads are served by drawing power from the grid. Here the traditional electricity meter gets replaced with ‘Net Meter’ which keeps track of import and export of electricity.
Off-Grid Roof Top Solar Power Plant
In Off-Grid Solar Power Plant we can design the plant in such a way so that, we can utilize the required power during daytime & extra we can store into the battery which we can then re-utilize during evening & night. We can also use the stored power during state electricity board power cut. A Bi-directional off-grid Inverter is used which at first fully charges the battery bank and then the remaining generated power is used for running the appliances and consumption. Off-Grid system is very useful in areas where there is frequent power failures and in remote locations where there is no access to grid connectivity. Commercially feasible plant capacity – 1 Kwp to 10 Kwp. Can be easily deployed in shops, schools, Institutions, residences, offices which are prone to frequent power outages.
Hybrid Rooftop Solar Power Plant
Hybrid Rooftop Solar Power Plant is the combination of both Grid Tied & Off-Grid Rooftop Power Plant. Hybrid Solar Power Plants are highly economic and efficient as compared to both Grid and Off-Grid Solar Systems. We can enjoy uninterrupted power supply even in case of state electricity shutdown and grid connectivity.
