SOLAR ROOF TOP MARKET ANALYSIS OF ODISHA

1. SOLAR ROOFTOP POTENTIAL IN
ODISHA

2. PROJECT ON CONSUMER SIDE OF METER
• Only one project of 500 KWp Rooftop Solar PV Project was installed at the Kalinga Institute of
Social Sciences.
• The State targets a capacity of 50 MW through such solar projects during the policy control period.
• 100 kW to 500 kW wherein aggregation of capacity from smaller roofs is allowed. 30% of the cost
would be provided as subsidy and 70% to be met by the consumer. Systems are to be grid
connected and do not have battery back-up. Surplus solar power from the project is fed to the grid.
• GRIDCO shall procure power from such projects in accordance with the OERC regulations for
net-metering/gross metering from time to time.
• Eligible developers are allowed to avail the relevant subsidies and incentives from MNRE under
JNNSM scheme. Further, State Government shall give incentive of 50 paise per unit of gross
generation from systems installed by residential consumers under this scheme

14. COST SAVING PER 2KW
• System capacity = 2 kWp
• CUF :19%
• Capital Expenditure = INR 88,000/KW
• Monthly generation in Bhubaneswar = 330units
• Energy loss due to grid outage in Bhubaneswar = 10 units
• Net generation = 320 units/month
• Grid electricity rate = INR 5.4 /unit
• Waived off electricity bill = INR 1728 /month
• Total benefit per year = INR 20736
• Tax Benefit = 20.008%
• Total Benefit =INR 24883.60
• Payback period for the investment = 7.07 years
• Grant/subsidy/bulk purchasing will help in reducing the capital cost
of the system and then reduce the payback period.
• TARIFF CALCULATION

15. CONCLUSION:
• Roof top solar PV systems have great potential.
• There is a need for awareness creation both about rooftop solar PV
systems/ technology packages as well as about the financing
avenues available.
• There is need for standardization.
• The policy support is essential in terms of regulations for net
metering, grid interconnection, and energy accounting.
• There is a need for promoting large scale, local manufacturing of
dual function inverters (functionality of both grid-tied and hybrid
inverters) to reduce cost.
• There is need for technical innovations in storage technologies -
mainly to reduce costs and improve efficiency.
• Roof tops solar PV systems can play an important role in providing
reliable and assured power for buildings and establishments.
