PROJECT BRIEF DETAILS

  • Vikram Solar, one of India’s leading module manufacturers and a prominent Rooftop & Ground Mounted EPC solar solutions provider, commissioned rooftop solar plant for Damodar Valley Corporation (DVC) at Ramakrishna Mission, Belur Math, the headquarters of Ramakrishna Math & Ramakrishna Mission.

  • A Swachh Bharat Mission initiative of Damodar Valley Corporation (DVC), the rooftop solar plant will power 6 buildings at Belur Math- Shilpvidyalaya, Shilpamandira, Shilpayatan, Shikshanmandira, SBI Bank and Showroom. The 164 kWp rooftop solar project is spread across 1975 sqmtr. (approx.) of rooftop area & is expected to generate 2.38 lakh units of electricity per annu

CHALLENGES & SOLUTIONS

  • Vikram Solar carried out a technical feasibility assessment and a highly-customized rooftop solar installation strategy to install & commission the prestigious project.
  • As the premise falls in a restricted area & inside a complete silence zone, so continuing with construction work after 8 pm was tough. Vikram Solar’s EPC team chalked out a feasible plan, worked for stretched hours on a regular basis to meet the work completion deadline. Adequate support were received from the Team DVC and the Ramakrishna Mission.
  • Also stringent quality control process was implemented from layout designing to module installation. The area is surrounded with trees, so engineering team required to design the plant layout in such a way that the shading effect could be mitigated. Modules were also installed on metal sheds.
  • Considering undulated rooftops, engineering team required to plan accordingly to avoid any complication during MMS construction &
    module installation.

PLANNING & EXECUTION

Total 477 nos. solar PV modules were installed in the 164 kWp rooftop solar plant.
The plant will power Six buildings at Belur Math:
  • Shilpavidyalaya: 33.81 kWp with 98 nos. of modules installed
  • Shilpamandira: 39.33 kWp with 114 nos. of modules installed
  • Shilpayatan: 23.46 kWp with 68 nos. of modules installed
  • Shikshanmandira: 45.54 kWp with 132 nos. of modules installed
  • SBI Bank: 12.08 kWp with 35 nos. of modules installed
  • Showroom: 10.35 kWp with 30 nos. of modules installed
10 kW-2nos. ; 20 kW-3nos. ; 33 kW-2nos. of inverters were used in the project.

CHALLENGES & SOLUTIONS

From the outset, the installation site presented unique challenges, including a large single shed roof, a requirement for large DC wiring underneath the modules, and two paths of evacuation converging into one outgoing source, which is atypical.
.
Like all our rooftop projects, client’s needs and situation varied. Vikram Solar carried out a technical feasibility assessment and a highly-customized rooftop solar installation strategy to install & commission Eastern India’s Largest Single shed rooftop project.

PLANNING & EXECUTION

Total 6240 nos. solar PV modules (approx.) were installed in the 2.15 MW rooftop solar plant. On an avg. 450 nos. of modules were installed per day to meet the challenge to complete the commissioning within deadline. 50 kW (1 nos.), 100 kW (17nos.) inverters used in the project.

RESULTS

Expected Annual Energy Yield 2.38 lakh unit. The plant is also expected to reduce CO2 emissions to the tune of 201.72 tonnes annually.
