Project DescriptionBy installing and successfully operating 10 MW photovoltaic (PV) power plants will deliver electricity for consumption by the owners, the relevant peoples in the project assessment place will be made aware of the technical and economic potential of solar power generation. Furthermore, the power required from the public grid will be reduced, and overall expenditure on electric power will be lowered & our project aims to create the necessary awareness among the population, and especially among policymakers and large investors, Youngsters.....

Bank loans for Solar PV Plant setup
2 kinds of Financing mechanisms
Recourse Financing Non-Recourse Financing
Loan could be in the range of 40-60% project cost
![Page 24: Project Proposal on 10 MW Solar PV Power Plant](https://reader036.fdocuments.in/reader036/viewer/2022062316/58f9ad84760da3da068b9915/html5/thumbnails/24.jpg)
CDM & REC Benefits REC Mechanism and CDM are mutually exclusive and
hence a power developer can claim CDM benefits
(Carbon Credits) also.
REC Principal Regulations, there is no lower limit for
Solar Power plants to be eligible for RECs. Though it
previously stated that 250 KW is the minimum size
for plants to be eligible for RECs, the same has been
removed as part of the above stated amendment.

No SubsidyCentral Government through MNRE
For systems Upto 100 kWp in size, Upto 15% subsidy can be availed with the help of MNRE-empanelled channel partners.
Solar Energy Corporation of India
For systems of sizes 100 kWp-500 kWp, subsidy can be availed through Solar Energy Corporation of India.
