OUR UPCOMING PROJECTS
IOT ENABLE SMART SOLAR TREE
The use of solar Photovoltaic (PV) technology is increasing rapidly owing to the huge demand for energy especially in the urban areas. Solar PV installations require approximately 8-10 m2 of land per kW of installation. In order to meet the energy demands of the urban dwellings, there is a dire need for a solution with high energy density. In addition, with the large scale grid integration of renewable energy source , grid stability has become an issue. Hence, it is desirable to achieve a relatively uniform energy generation from solar PV installations throughout the year. Also, due to the large transmission losses and curtailment, there is a need to move toward decentralized energy generation.
A 3 kW IoT enabled smart solar tree is developed & demonstrated. Optimized solar panel placement is achieved to minimize shading losses to less than 5% and provide a levelized energy generation throughout the year.The complete system is enabled with an IoT sensor platformfor performance and environmental parameter monitoring.
Applications:
- The solar tree can be used in smart citie.
- The conventional agriculture can be upgraded to smart agriculture.
- Smart highways with EV charging station
- Sustainable and green EV mobility
SOLAR GRID TIED/STAND-ALONE HYBRID INVERTER
A solar grid-tied/stand-alone hybrid inverter is a type of inverter used in solar power systems that combines the features of both grid-tied and off-grid (stand-alone) systems.
Key Functions:
1. Grid-Tied Mode:
o When the utility grid is available, it synchronizes with the grid and supplies solar
power to the home.
o Excess power can be exported to the grid (net metering).
o If solar is insufficient, it draws power from the grid.
2. Stand-Alone (Off-Grid) Mode:
o If the grid goes down, it switches to battery backup.
o It supplies power from the batteries and/or solar panels to critical loads.
o It works independently of the grid during outages.
Hybrid Features:
Battery Integration: Supports charging and discharging of batteries.
Smart Energy Management: Can prioritize solar, grid, or battery power based on demand, time of day, or cost.
Seamless Switching: Automatically switches between grid and battery without interruption.
Social Benefits:
Grid current THD is less than 5% for nominal loading , Galvanic Isolation feature provided , No battery is required , System protection: Over/Under voltage, Over/Under frequency, Short Circuit; Over Current Protection.
SOLAR PUMP SET WITH MPPT CHARGE CONTROLLER:
The system consists of four components: PV cell, drive , motor and pump. The built-in power point tracking functionality enables the pump to run at a maximum power using solar power. It is independent of the grid and produces no pollution or noise.
Solar pumping solutions are becoming increasingly popular among Indian farmers irrigation, forestry, fish farming, and fountains in residential areas. Submersible Pumps can also be used with solar pump Various reasons impacting productivity, such as load shedding, electricity supply cuts and increased energy prices, as well as burnt motors caused by voltage fluctuations, can be avoided with the solution.

The solar pump inverter is an AC drive of 5 HP, designed to operate with energy drawn from photovoltaic cells (PVs). A DSP-based control tracks and extracts maximum power from m the solar panel so that motor runs with the intensity of sunlight throughout the day.
Features:
Smooth sine wave without voltage peaks
Low cost and easy maintenance
No limitation on cable length
Sinusoidal output voltage and current
Temperature independent maximum power point tracking (MPPT)
Used as single-phase house supply (when pump is not in use)
Galvanic Isolation feature provides natural accidental protection
Dynamic V-I MPPT control method
Variable frequency drive (VFD) to provide maximum torque with minimum sunlight
Inverter efficiency is more than 90-93%, with high reliability
System protection: Over-voltage, short circuit, overheating and over current protection
For pumping application in drip irrigation system, fountain system, etc.
Intelligent power module (IPM) for the main circuit with high reliability
