Innovative Design

13. Maximization of Savings
Challenge
Commercial mall in Pune
Limited space compared to huge load
High power tariffs (Rs. 14 per KWh)
Solution
Reduce tilt angle from 180 to 50
Maximization of the capacity 300 KWp  565 KWp

14. Maximization of Savings
Benefits
Achieved generation of 1480 KWh/KWp/Year
Savings up from Rs. 48 lacs to Rs. 87 lacs

15. Complex Roof Challenge
Multiple obstructions on the roof – columns, water tanks
Design of structure – too complicated
Shadows from Trees
Solution
Utilized existing columns
Structure raised above water tanks
Uneven structural legs
Benefits
Capacity up from 30KWp to 100 KWp
Excellent generation : 1450 KWh/KWp/Year (in spite of shadows)

16. Limited Roof Space

17. Multiple Evacuation Points
Challenge
Evacuation over 17 buildings
Long AC and data cabling – increased losses
Road digging and crossing
Solution
Energy meter for every evacuation
Power Controller in Master-Slave mode – Central monitoring and local control
Leveraged local LAN
Benefits
Reduced losses by reduced AC cabling
Reduced data cabling
Avoided road digging and crossing
Lower overall cost of the project
Monitoring of wingwise and cumulative data

19. Tracker for Ground Mounted !
Features
Row Tracker – each row individually powered
Can handle 150 slope in N-S direction (on ground)
Offers higher power density per Sqm (32 KWp/50m)
Customized algorithm tracking true solar position
Large tilt angle (- 550 to 550 )
Quick reset to stowage position (stormy weather).

20. Tracking for Rooftop ! Benefits
Steady power supply – the curve is smoothened
Steady power at morning as well as evening
Higher generation for same capacity
Economics : 17% more power for 11% incremental cost.
