SOLAR POWER FOR BHARAT NIRMAN RAJIV GANDHI SEVA KENDRAS
Largest Off grid Project in India-10MW
…G2G Initiative


Bharat Nirman Rajeev Gandhi Seva Kendra under
Rural Development & Panchayat Raj Department,
Govt of Rajasthan for 248 nos. of Panchayat Samities
& 9177 nos. of Gram Panchayats are provided with
computers to promote sustainable solutions for
improving the quality of life in rural areas by providing
digital connectivity
In order to achieve these objectives the computers
are to be provided with reliable energy backup of SPV
Systems by REIL at all the Bharat Nirman Rajeev
Gandhi Seva Kendras in Rajasthan

Online Monitoring through www.reilsolar.com
Monitoring of SPV Systems
 Online monitoring of all activities from installation to
commissioning.
 Smoothens Project Execution
 Transparency by providing all information on the web.
 Enhanced Progress
 Benefits in monitoring/execution of the project to REIL as well as
the Government agency
 Complaint handling via web, call center
 Quick Response by SMS after installation of system
 Efficient MIS reporting system.
 Monitoring of activities of SPV systems & other associates like
BSNL,RKCL,CSC, eMitra, Minibank, Satcom.
 Information flow on the web also presents the humane face of
administration and helps build trust and faith in government.
