• World Energy mix shifting towards renewable
• Wind and solar make up almost 50% of worldelectricity in 2050 – “50 by 50” –
• It will help to keep the increase in global averagetemperature to well below 2 °C above pre‐industriallevels; *Source: BP Magazine,Bloomberg NEF,REN21

Presentation TitleG&B Offering - Differentiated Rooftop Approach
Different approach for different customer after understanding needs & expectation of customers plays key role for bagging order
Before Installation waste location Simulation Phase
Final InstallationDuring execution
Case Study: Sudarshan Chemicals, Pune
Feedback from Customer:
• Awarded priority vendor category status to Godrej
• Bagged 210 kW (INR 1.16 Crs) order of Deccan Explotech, Pune based on positive recommendation by customer
• Repeat order of 1.2 MW expected in phases
Order Details:
Plant Capacity: 375 kWp Location: Pune, India
Presentation TitleDifferentiated Rooftop OfferingsProject Uniqueness:
• Unevenness of canal topogrphy• Corrosive environment inside refinery –
Structures to be guaranteed for minimum 15 years
• Limited Space available for O&M• Strict safety compliances
Before Installation Simulation Phase
Final InstallationDuring execution
Case Study: BPCL Canal Top – 348 kW, Mumbai
Solutions:
• Earthing Foundations (140 Nos. dug manually as no DTH, Augur machine allowed)
• Structures: Sand Blasting and Polyurethane paint used for structure life of minimum 15 years
• Common foundations used for adjoining trusses and movable walkway and railing after 20 mtrspace WalkwayRailing
Differentiated Rooftop OfferingsProject Uniqueness:
• Non availability of space at roof level.• Various equipment installed at roof level i.e.
chillers, cooling tower.• Solar generation required for IGBC Green
Certifications
Solutions:
• Vertical mounting solar power plant• Used of vertical façade wall for solar module
installation• Solar plant installation done with out affecting
area at roof level.• Building certified for green Building council.
Case Study: Vertical Solar Plant – 20 kW, Hyderabad
Before Installation
After Installation
Best Practices – O&M
Provision of Water line near to solar
panel for ease of cleaning
Walkway parallel to ground for safe and
efficient work
Horizontal Walkway for Comfortable walking
Water Line on each bay Ergonomic and Safe Step for Cleaning
Quick release
clamp for reduction
in cleaning time and ease for
work
Integrate water
cleaning brush reduce
operator fatigue as
well as save water
Quick Release coupler (QRC) Ergonomic Water Cleaning arrangement
Pull Out Test Safety Railing on Roof Top
Electromagnetic lock
Roof Ladder Access Control RFID System
Best Practices – O&M
Wind direction
Differential Dust accumulation on roofs due
to difference in height of the roofs & location of the
building.
Time Based Cleaning does not ensure high performance
all the time.
