WHY GO SOLAR?
ABUNDANT
Completely free, abundant natural resource
Rapid depletion of conventional sources of energy like fossil fuel
ACCESSIBLE
Used any time during the day
Easy and safe to install
Govt. of India is pushing for increased adoption of non conventional sources of energy through subsidies
SUSTAINABLE
Though initial installation costs are high, long term benefits in terms of energy and money are significant

Project Selection
There is an existing proposal under way in IIM Indore to install Grid connected roof top solar panels to make the buildings solar enabled.
The proposed solar project’s monthly capacity will be 4800kWh while the current monthly usage of electricity is 17000kWh.
Hence, the focus area of our project is Facilitating Solar Streetlight enabled campus.

A solar panel with 20% efficiency and an area of 1 m2 will produce 200 W at Standard Test Conditions[1].
With an average exposure of 5.5 kWh/m2/day, the panel can be expected to produce 440 kWh of energy per year.

Pole
LED
Fixtures
Potential Areas we can target:
Street lights in and around SR-15, SR-17 & FPM
Street lights in and around Academic block
Street lights present on the way towards New Auditorium & Academic block
Reason behind selecting these areas: Continued exposure to sunlight

Basic statistics
No. of Street lights available on campus= 750
Wattage employed = 70W mostly, a few have ratings of 150W & 250W
Present cost per unit of electricity= Rs per kWh.
Average daily hours of operation= 10 hrs.
No. of hours of sunlight daily= 6
Derating factor=0.8(Losses in conversion of DC to AC)
Maintenance costs incurred currently= 20lakhs per year.
Solar units generated per day= 70W*750 *0.8*6= 252kWh (kW *derating factor * No. of hrs of sunlight)

Recommendations
Capex model-option-1
Cost involved to install 1 solar enabled street light = Rs
Total initial investment required= 750 *15000= 112.5lakhs.
Subsidies by state & central govt. = 35%
Net investment required= lakhs.
Per year tariff = No. of days in a year * No. of solar units produced per day * present tariff
= 365*252*6.4= 5.886lakhs.
Pay back period = /5.886= years.

Recommendations
Resco model(Renewable energy service model)
Initial Investment= 0
Per day electricity consumption of 750 street lights= 750*70W*10= 525kWh
525* 6.4= Rs. 3360
Per day solar energy generated = 252kWh.
5.4( In RESCO model)= 252*5.4= Rs
Total savings per day = 252*( )= Rs 252.
Total savings per year= 365 *252= Rs
