The REIL entered into the Solar Photovoltaic industry in 1985.
It started its operation by setting up a manufacturing facility for SPV
modules.
The Company has a capacity of 2 MW per year on single shift basis.
Solar Photovoltaic based application products, sub-systems and
integrated systems most of which were developed in-house, in theSPV segment.

In renewable energy division, REIL offers a wide range ofstate of the art of Solar Photovoltaic module.
These modules are ideal power generation at remote areas,where conventional power is not available or power supply iserratic.
It is noiseless, non-polluting and maintenance free source ofenergy.

Photovoltaic are solid-state semiconductor devices that convert light
directly into electricity.
They are usually made up of silicon with traces of other elements
and are similar to transistors, light emitting diodes (LEDs), and other
electronic devices.
The photovoltaic device (usually called a solar cell) consists of
layers of semiconductor materials basically silicon with different
electronic properties.

A solar cell has silicon with impurity atoms mixed in with the siliconatoms.
In photovoltaic module both N-type silicon and P- type silicon are
used.
Photovoltaic cell always has at least one electric field.
Without an electric field, the cell wouldnt work and this electric field
is formed when the N- type and P-type silicon are in contact.

PV system are categorized into three types as autonomous, hybridand grid connected.
1. AUTONOMOUS SYSTEM :
(a.) They are completely independent of the other powersources.
(b.) These types of system are generally used to providepower remote homes, cottages etc.
(c.) in most cases , an autonomous system will requirebatteries for storage.
2. HYBRID SYSTEM :
(a.) Hybrid systems receive a portion of their power fromone or more additional sources.

(b.) In practice, PV modules are often paired with a windgenerator or a fuel-fired generator.
(c.) Such systems usually require batteries for storage.
3. GRID-CONNECTED SYSTEM :
(a.) This systems allows to reduce consumption fromthe electricity grid.
(b.) Since power is normally stored in the grid itself,
batteries are not necessary unless you want some
form of autonomous power.
(c.) These systems are used in buildings, homes orcottages already hooked up to electrical grid.

Solar cells, also called photovoltaics (PV) by solar cell scientists,convert sunlight directly into electricity.
Solar cells are often used in power calculators and watches.
They are made up of semiconducting materials similar to those usedin computer chips.
These material absorb the sunlight , thereby knocking out loose
electrons from their atoms, allowing the electrons to flow through thematerial to produce electricity.
This process of converting light (photons) to electricity (voltage) iscalled thephotovoltaic (PV) effect

(a.) 38 WATT Module :- 36 cells are connected in series. TheO/P voltage is approximately 0.45V to 0.5V and the O/P
current is approx. 2.2A
(b.) 75 WATT Module :- A total of 36 cells are connected inseries, which is called string. But the cells used are pseudo-
square having O/P voltage 0.45V-0.5V & O/P current 4.5A.
(c.) 150 WATT Module:- A total number of 72 cells are
connected in series. The O/P voltage, current and power ofeach cell is same as that of 75-watt module.

The Hubbell telescope utilizes solar panels for its energyrequirements.
Locally produced car batteries can provide up to 5 nights ofenergy for 8 watt DC.
Some electric lighting systems provide sufficient current up to 10hours of lightning each evening.
A photovoltaic (PV) or solar cell is the basic building block of a PV
(or solar electric) system. To boost the power output of PV cells,we connect them together to form larger units called modules.Modules, in turn, can be connected to form even larger unitscalled arrays.
