Important Information:  

1. The NREDCAP had called for tenders and the price discovered is as follows.

  • 5 HP AC solar pump-set system:Rs.4,90,000
  • 3 HP AC solar pump-set system:Rs.3,20,360
  • 5 HP DC solar pump-set system:Rs.5,40,000
  • 3 HP DC solar pump-set system:Rs.3,84,015

      2. The cost system will cover

  • Solar panels of appropriate size
  • High quality ISI pump-set
  • Transportation of all equipment‚??s to beneficiary site
  • Mounting structures & civil works as required at the site
  • Electrical cables
  • Water pipes of different sizes, up to 100 feet depth
  • Cost of installation and commissioning
  • Charges for annual maintenance contract (AMC) for 5 years
  • Insurance premium for 5 years
  • All taxes as applicable
  • All other accessories, please refer to the technical specifications for details

       3. The cost will be borne by various stake holders, as follows

       Case-1:Beneficiary funded pump-set  

MNRE would provide Rs.32, 400 per HP for AC pumps & Rs.40, 500 HP for DC pumps for 3HP & 5 HP pump-sets. Remaining costs will be borne by the farmer.

      The following table provides the cost estimates.                


Type of pump-set

MNRE subsidy(A)

Beneficiary contribution(B)


3 HP AC solar pump-set




5 HP AC solar pump-set




5 HP DC solar pump-set




5 HP DC solar pump-set





Case-2:Additional Finance from other Govt. Departments

The Departments like ITDA, Agriculture, Horticulture etc., may provide additional financial assistance for the Pump sets in addition to the MNRE subsidy so as to reduce

                 the burden on the beneficiary / farmer.

      Case-3:Pump-sets funded by APDISCOMS:

       For the farmers who do not possess agricultural connection, Farmers whose applications for release of connections are pending with the APDISCOMS would be given priority under this

  scheme. The following table provides the cost estimates. 



MNRE Subsidy @32,400/HP (A)

Beneficiary share        (B)

Discom Contribution (C)

Funding Requirement (D)









5 HP AC solar pump-set







3 HP AC solar pump-set







    4. If the solar pump-set is funded by through the scheme as mentioned in Case-1(through beneficiary funding model) the ownership & title will lie with the farmer.

         If the solar pump-set is funded through the scheme as mentioned in Case-3, then the title & ownership will lie with the respective APDISCOM,

        as the loan from funding agency will be paid by the respective APDISCOM.

    5. The farmer will be responsible for the safety & security as the system is located in the premises of the farmer.Secondly, the solar pump-set is utilized to supply water to the farmer only, so the beneficiary

would be customary guardian of the system. Thirdly, the insurance does not cover any kind of physical damages caused to the solar panels, pump-set or the associated equipment due to negligence and /or

mollified intentions. The farmer has to take adequate precautions such as fencing the area to keep of cattle or stray animals away from the system.

    6.Technical feasibility will be granted after a joint inspection of the farmer‚??s premises/land by a team of DISCOM & NREDCAP officials. They will inspect various things such as     

  • Availability of 270/450 sqft shade free land for 3 HP/5 HP system
  • Willingness of farmer to forego agricultural use of the land
  • Depth of water table (Between 150-200 feet depth from ground level)
  • Distance from the coastline(At least 20 kms straight line distance from the coastline)
  • The farmer shall not possess any agricultural service connection from respective DISCOM for case-3 beneficiaries.

      7. The solar panels & associated pump-set are based on advanced technology that requires minimum manual intervention. The system operates automatically when the switch is pushed on

manually.Therefore no dedicated operations personnel is required. However, the solar pump-set would require routine cleaning of the panels that can be attended by the beneficiary. As per the requirements,

         the supplier company will open service centres and will recruit technicians for every district. The cost of the system covers AMC charges & insurance charges for first 5 years.Thereafter the cost of servicing,

maintenance, and repair, insurance has to be borne by the farmer. It is advisable (but not mandatory) that on completion of 5 year AMC, the farmer extends the AMC period at his/her cost. In a few words,

       the company which has supplied /installed the solar pump-set will be responsible for maintaining. The farmer does not have to pay anything up to 5 years period, but will have to bear any charges (as applicable) thereafter.
