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

3. Why Solar Ready 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
Safety during installation
Less Installation time

4. Study Case – Large Manufacturing Industry
North
Central Ridge Line
210 ft
Roof Layout
570 ft
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
Roof Layout
Takeaway: Industrial roofs should be designed with minimum load bearing capacity of 18 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 Rs. 8 ~ 11 / Unit (Variable Tariff only)
Takeaway: Virtual Roofs / Superstructures may offer viability on Solarising Terraces in Metro Cities over Buildings

7. New Approach – Solar Roofs
Central Ridge Line
North
Solar Ready Roof
Capacity
5000KW
Capex: Rs.25 Cr
Payback tenure: 5 Yrs
Net Savings: 117 Cr
Solar Ready Roof
480 m
136 m
Roof Layout
Takeaway: Designing Solar ready roofs at pre-construction project stage optimizes solarization possibilities for the industry.

8. New Roofs optimized for Solar Power
