14. PRICING TREND IN SOLAR PV

15. CURRENT PRICE OF ROOFTOP MARKET
ROOFTOP MARKET:
• Prices vary from 52 RS/ Wp to 60 Rs. / Wp
• Prices depends on the following:
 size of the roof.
 Evacuation Voltage
 Type of roof ( Trapezoidal/ high seam/ RCC)
 Inverter selection
 Module configuration
 Misc. requirement
In the range of 42-44 USD Cents/ Wp
Modules
String Inverter approx. 6 Rs/ Wp without tax.
Inverter
RCC ROOF: Approx 3-4 Rs/ Wp, metallic roof approx. 2 Rs/
Wp
Structures

16. TREND OF SOLAR PV PRICING
WHAT ARE THE REASON FOR THE DROP IN SOLAR SYTEM PRICING?

17. REASONS OF LOWERING OF SOLAR PV
PRICING
1. Drop in Module Price.
2. Optimization of Engineering i.e. DC: AC ratio
3. Entry of New manufacturers in the market
4. Customized solutions
5. Increase in Size of the project
6. Reduction in BOS price due to higher
efficiency of Modules
7. Reduction in structure weight due to better
