Our Solution

After assessing their energy needs, we planned this:

  • 450 Wp x 420 Longi Monocrystalline Half Cut Solar PV modules were used.
  • Each solar panel also had a DC optimizer capable of 950W. The product is often seen in Western countries due to its high-tech nature.
  • Their rapid shutdown technology ensures the utmost safety. As it’s contained in the conduit running from panel to panel to the inverter, it’s generally safe.
  • The tower is designed to withstand wind speeds of 180 Kmph with an on-grid commercial solar power plant rated at 189 KWp and a hot-dip galvanized tier steel structure.
  • The Lightning Arrestor is mounted at suitable locations and is carefully calculated and positioned to protect the system from lightning strikes. Parallel-connected earth pits are provided in LAs to keep earth resistance as low as possible.
  • This solar inverter is a Solar Edge 27.6 KW x 6 MPT model, which makes a more robust system.
  • A total of 420 modules were used in New Kolkata.
