OFF GRID SOLAR POWER PLANT
OFF GRID SOLAR POWER SOLUTION ( From 1 KW to 100 KW- Single & Three Phase output )
This consists of Solar PV Panels, Hybrid Solar Inverter , batteries, Mounting structures and other accessories. Solar PV will convert the Sun energy to Electrical energy. Inbuilt Advanced MPPT Charge controller in the Hybrid inverter will convert the uncontrolled DC into Constant DC to charge the batteries and to feed to Inverter. Hybrid inverter will take power from Solar on priority and monitors the state of battery voltage, solar power output and the loads. This overcomes frequent battery charging and discharging which results in poor efficiency. It gives you the flexibility and ensures that batteries are always available to take the load.
Balaji Solar Solutions’s state of the art off grid solutions employs high efficiency world class Poly/ Mono crystalline panels.
ON GRID SOLAR POWER SOLUTION
A “Grid- tie” Solar system is one that ties into the power grid, pulling electricity from the grid when then pushing excess electricity back into grid when the local customer is not using the full capacity being generated by PV Panels. Since these system is tied to the grid, it follows the safety feature of disconnecting the system from the grid when grid goes down. This system does not provide backup power during power cuts ( even if sun is shining). But for the sites with reliable grid power and the day time usage are high, this is usually logical and economically viable system choice.
HYBRID SYSTEM
The working of the hybrid (solar+ grid) battery based system is depicted in the picture below. The brief working of the system and key features are as follows:
DIFFERENCE BETWEEN ON GRID & HYBRID SYSTEM
| Feature | Grid Tie System | Hybrid System |
|---|---|---|
| Working | Pumps the generated power directly to the local grid (LT panel) | Manages solar, battery, load and grid power |
| System size | System size is irrespective of connected load and only dependent on total power requirement | System is sized based on the power requirements of the connected loads |
| Power utilisation | Power is sent to the LT panel to be utilized by any load | Power is utilized only to the selected connected loads |
| Storage | None- Separate backup such as DG set is required | Battery bank to store power required for the selected load |
| Cost | Less Expensive due to simpler inverter and no storage | Higher due to more sophisticated solar inverter and batteries |
| Maintenance | Less (No batteries) | More (due to batteries) |
