2. India Rooftop Solar Mission Target
Rooftop Solar Power 40,000 MW
Roof Area 4.5 billion sq. ft.
70% of capacity from New construction (~$ 30 Bn)
Optimized Solar Roofs Vital
Solar Mission

3. Why Solar Roofs are Vital
Direction and Slope of the Roof with favorable for Solar Power Generation.
Design of the roof and Plant
Avoiding Shadow of any Big/ large chimney or equipment in concept or design phase itself
Walkways
Roof Aceess
Safety during installation
Less Installation time

4. Study Case – Large Manufacturing Industry
North
Ridge Line
Available Area: 120,000 sq. ft, Available for Solar: 37,800 sq. ft. only 315 KW against 1200 KW
Takeaways: 70% rooftop area wasted because of improper planning of the building; Loss of 23 Cr Rs. in potential savings.

5. Study Case – Large MNC
Available Roof Area : 2 MW;
Suitable for Solar: NIL (load bearing only up to 12kg/sq. Feet)
Lost opportunity of savings of Rs.52 Cr on electricity cost
Takeway: Industrial roofs should be designed with minimum load bearing capacity of 15 kg/sq. Feet or more.

6. Case Study: Virtual Roofs – Metro Cities
Metro Cities face challenge of ROOF area & installed with Utility Equipments. High grid tariff’s 12 – 15 Rs
Takeaway: Virtual Roofs / Superstructures may offer viability on Solarising Terraces in Metro Cities over Buildings
