B. System Description (Grid Connected System

The Solar electricity is produced when the Photons from the sun rays hit the generating electrons in the Solar PV panels

The DC electricity from the panels passes through DC distribution network to a grid

interactive inverter, which converts the DC electricity

operation. The inverters employ state of the art technology with IGBT methodology and

into the AC Grid.

Grid Connected System):

The Solar electricity is produced when the Photons from the sun rays hit the electrons in the Solar PV panels - this creates Direct Current (DC).

The DC electricity from the panels passes through DC distribution network to a grid

interactive inverter, which converts the DC electricity into 415/230V AC for 3/1 Phase

state of the art technology with IGBT methodology and


connect system has mainly 3 components:

PV array,

Module Mounting Structure and

Power conditioning Unit (PCU).

Modules: The indigenous Moser Baer - make, Solar Crystalline Silicon Modules will be used for

this system.

Power Conditioning Unit/Inverters: We propose to use Delta make or Equivalent inverter for

this proposed PV system requirements.

The PCU converts the DC Power into AC power and feeds into the grid. It is designed to give

high efficiency with IGBT technology. The PCU delivers the max. Power generated through solar

modules into grid due to its inbuilt feature of MPPT operation. The PCU has internal self

protection in case of any fault in the grid. Also the PCU has inbuilt contactors/breakers with

fuses for self protections.

The PCU has in-built microprocessor based controls. The Inverter is designed in such a way that

it will synchronize with the utility (grid) power with respect to the Voltage and frequency of Grid

and it corrects itself according to the grid parameters within its settable limits. The inverter will

sense the array power and grid power; if both are available it starts and stops automatically in

the morning and evening respectively.

100kWp PV System Integration:

The 100 KWp Crystalline-Silicon Solar Photovoltaic Power systems for this project comprise the

following major components and services.

• 100KWp Solar Array consisting of 414 no Moser Baer make C-Si PV modules of 240Wp (+/-

3%) each. No of modules will vary as per selection of module capacity

• Module mounting structures to mount the solar modules with special protection against

corrosion.

• 3 nos of grid connected String inverter of capacity 30KW each which is capable of 10-15%

higher DC input capacity. Output power is 400VAC, 50Hz. three phase, 3-wire

Each Inverter has in-built data logger and monitoring device

• Mounting hardware and system DC & AC cabling

• AC Distribution panel for Grid isolation and energy meter (KWh) reading

• Project Management including, design, supply, installation & Commissioning of the PV

system.

• Project Management Documentation, various drawings of required mechanical, civil and

electrical.

F. Typical Module Mounting Structure

MS Galvanized mounting structure as per the requirements of the project and to installed

maximum nos. of modules in min. area. The structure is designed in such a manner that module

can be replaced easily and in line with site requirements and it is easy to install and service in

feature.

Mounting Structure will support SPV modules at a given orientation, absorb and transfer the

mechanical loads to the ground properly and will not any requirement of welding or complex

machinery at site.

The structure is designed in such a way that it will take less space and will withstand wind load

up to 150kM/hr.

All fasteners, nut and bolts are made of Stainless steel - SS 304 5.4.6 PCC

FOUNDATION BASE: The legs of the structures made with GI angles are made of fixed and

grouted in the PCC foundation columns made with 1:2:4 cement concrete.

All the cables will be supplied conforming to Indian/international standard IS 694/IS 1554,IEC

60189,IS/IEC69947 & shall be of 650 V/ 1.1 kV grade as per Interconnections, array to junction

boxes, junction boxes to PCU etc will be so selected to keep the voltage drop and losses to the

minimum.

The bright annealed 99.97% pure bare copper conductors that offer low conductor resistance,

they result in lower heating thereby increase in life and savings in power consumption. These

wires are insulated with a special grade PVC compound formulated and manufactured in-house.

The skin coloration offers high insulation resistance and long life.
