Solar Project Materials – NR Tech Products

Electricity is one of the world's fastest-growing form of end-use energy consumption. It is estimated that, world energy consumption will increase by 56% by 2040. Renewable energy and nuclear power are the world's fastest-growing energy sources, each increasing 2.5% per year. Net electricity generation worldwide will rise by 2.3 percent per year on average from 2007 to 2035 as compared to 1.4 percent per year growth for total world energy demand. Our aim is to go hand by hand in this journey with all infrastructure players. Major terms & materials are listed below.

We welcome to receive your inquiries for any item:

Photovoltaic - The physical effect of direct conversion of light (sunlight) to electrical energy

PV Cell - The smallest photovoltaic (PV) element that generates electricity from light

PV Module - A collection of interconnected PV cells, encapsulated between protective materials such as glass and back sheet (Poly Vinyl Fluoride) or glass and glass, and mounted in an aluminium frame. This is a hermetically sealed unit

Array - Several strings of modules with the same orientation and tilt angle, located together

Inverter - An electronic device that converts direct current electricity into alternating current electricity suitable for feeding directly to the electrical grid or to normal AC loads

Insolation - It is a measure of solar radiation energy received on a given surface area in a given time. It is commonly expressed as average irradiance in watts per square meter (W/m²) or kilowatt-hours per square meter per day (kW·h/ (m²·day)) (or hours/day)

Mounting Structure - Device used to hold modules in place, at desired angle &direction

Power Evacuation - Power generated from Solar PV Power Plant is transmitted to a point (sub-station) where it is distributed for consumer use

Sub-station - The place where the generated power from solar is synchronized with utility grid and metered

Control Room - Room housing control equipment

Cable - A conductor with one or more strands bound together, used for transmitting electrical energy

Junction Box - Inputs of several strings are connected to this box and taken as single output

Current - A flow of electricity through a conductor measured in Amps

Voltage - The rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in volts. It is the difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts. It is the measurement of the potential for an electric field to cause an electric current in an electrical conductor

Lightning Arrestor - Device used to protect all the components from lightning strikes

Transformer - An electrical device by which alternating current of one voltage is changed to another voltage

Grid - A system of high/low tension cables by which electrical power is distributed throughout a region

SCADA - Instrumentation & Control system for the solar power plant used to detect malfunctions and give information at a given time interval about the availability and performance of the plant
