Project Description
The purpose of this project is to install Solar Photovoltaic
(PV) 15 KW off grid solar power plant. This plant may be utilized to serve the
needs of Wapco.
WABCO
INDIA LIMITED, a majority owned subsidiary of WABCO Holdings Inc, has
pioneered the manufacture of air-assisted and air brake systems for commercial
vehicles in India.
Solar Power
With the fast depletion of the non-renewable energy
resources, there is a tremendous thrust on generating renewable energy. Solar
Energy has been identified as one of the driving forces for generating
electricity. During the last two decades, the accelerated drop in silicon,
which is the feedstock material for most panels, has made it possible for solar
panels to move from space-based applications to generation of energy for
consumption by the general populace.
The solar power industry is growing at a phenomenal rate
globally with the US, Germany, Spain and China leading the way. Industry
experts predict an annual growth rate of about 40 per cent for several years
into the future. With escalating international oil prices and increasing
concerns about global warming, solar power represents a strategic energy choice
for the future for most of the countries currently dependent on imported energy
sources.
Similar considerations apply in India as well. Further, there
has been a rapid decline in the PV pricing in the last 2-3 months which has
made a well-designed Solar power solution a better option, environmentally as
well as financially to a DG (Diesel Generator Set) power. Due to a massive deficit in the power sector
infrastructure and fuel supply use of DG has been growing rapidly in India.
This has led to many issues including a rising oil import bill, loss of revenue
due to subsidies for diesel and above all, increasing pollution in the country.
Solar
PV (Photo-Voltaic) Technologies
There are two main PV technologies namely Silicon
(mono-crystalline or poly-crystalline) or thin films (TF). The latter includes
amorphous silicon and various chemistries from the CIGS (Cadmium, Indium,
Gallium and Selenium) family of elements.
Though TF panels have better thermal characteristics
then Silicon based panels, their lack of long term record makes them a riskier
alternative. Further due to their
considerably lower power density requires a higher number of panels resulting
in a higher space requirement and BOS costs. Poly-crystalline panels have
better thermal characteristics compared to mono-crystalline panels hence are
considered more suitable for our needs.

Racking System Installation
Once the feasibilities studies are completed, sturdy racking
system will be installed on the ground which will be able to support the
panels. This is a standard Ground Mount
racking system.
PV Panels Installation
PV Panels
will be installed on the racking system at an angle facing the southern
direction.
Connecting
Once the PV
Panels have been installed, the system will be completed after adding the
inverter.
The following are the key requirements for the project to be developed.
Permits
All associated permits required for
the project will be the responsibility of the project owners and will be
provided prior to the project commencement or at a mutually agreed point in
time. All Clearance and Permits required for the

Technical
Specifications for a 15KWp (DC) Installation
This system will require a space of 1500 SQUARE FEET
of Roof top to install. It is imperative that there is no potential for shadows
as that will impact the performance of the panels.

Electrical Wiring
There are
various types of wirings that are utilized on site. These vary from low to
medium voltage DC and medium to high voltage AC. In each of the cases we use
the best all weather and where required UV protected cables. The key is to keep
our resistive losses (I2R) to the minimum for maximum efficiency.
Fault Protection
Our engineer team designs the
system with proper grounding including double isolation disconnects where
required and fully protected system. Our system includes protection of the AC equipment
against lightening using arrestors etc.
Monitoring
This is an optional feature that
we provide. Based on the accessibility many of the metrics related to
performance including output and fault logs can be made available
remotely. It is possible for people from
across the world to monitor the performance and display related graphics on
their laptops/desktops or similar device.
