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 polycrystalline) 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.

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.
