Rooftop of Railway Coach (Different) Rooftop Rooftop of Railway Coach

Innovative Solutions Solar Plant as Roof for Car Park BIPV – Transperent Panels or Aesthetics at Railway Training Center Pune

Every Rooftop is Unique Requirements Challenges Solution

Case Study No. Topic 1 Multiple Evacuation 2 Maximization of Savings 3 Limited Roof Space 4 Tracker for Ground mounted 5 Innovative Design

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

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

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)

Limited Roof Space

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

Innovative Design RelyOn Solar

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).

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.
