Abstract: Arunachal Pradesh has been a major hurdle in achieving hundred percent
electrification target. Due to its distinct geographical location and weather
condition making the job of electrification process cumbersome. Not many
renewables energy companies are willing to invest or even take contractual work
there due to higher capital investment and low margin of profit.
In order to understand the crux of these issues, it was important to get in
touch with the grass root level field work of the region. Also being a native of
Arunachal Pradesh made me quiet natural affinity to work and dedicate myself
for the progress of the state. I had a unique opportunity to work under the
department of APEDA as a part of technical team, the objective of the team was
to work on the project installation and provide with the necessary
recommendation for the shortcoming from the contracting company to the
project in-charge. Recommendation from change of module technology, tilt
angle, cable used to till appropriate equipment (inverter, panel board) setting
direction were provided.
After the complete installation of first phase at Roing, the simulation of the
installed project was necessary to provide us with the detail projection of
generation data for the coming years and the revenue saving from the system.
The simulation of the project was done in Helioscope solar simulator software
and the power and energy generation from the project site analyzed.
Key Observations were:-
I. Energy generation at Roing was higher than Hunli by 4.1 MWh annually
for same 100 kW system.
II. Total energy demand for Roing and Hunli division is 4109.55 MWh
annually and the power generation from SPV will be 441.56 MWh
annually, thereby total saving will be of rupees 20.61 lakh (11%).
With the completion of this 400 kW project it became the largest SPV system at
eastern region of the state marking a new beginning and awareness of green
energy to the locals there and I believe that the state has lot to give from its
untapped resources in coming future.
