Green Living with 81 KWp On-grid Rooftop Solar Power Plant at Flora Fountain, Kolkata

Overview

Alcove Realty Flora Fountain is a self-sufficient residential project in Topsia, Kolkata. The Flora Fountain is a pre-certified GOLD Green Building project accredited by the Indian Green Building Council, combining nature, convenience, and fine living. To strengthen its IGBC accreditation, Alcove Realty partnered with SunShell Power to install one 40.5KWp solar rooftop power plant on each of its 2 towers. The solar power plants provide electricity for all of the common area amenities and recreation centres like common area lighting, community hall, lifts, surveillance system, sewage treatment plant, parking area, underpass lighting, communication tower, garden, and high-tech gyms.

Our Solution

After assessing their energy needs, we planned this:

• A Longi solar Mono parc Half Cut Solar PV module, each 450 Wp x 180.
• The inverter is Solis 40 KW x 2 MPT base.
• Lightning Arrestors are installed at suitable locations and are well-calculated and perfectly positioned to protect the system against any lightning strikes.
• Dedicated parallel-connected earth pits are provided for the LAs to maintain the lowest earth resistance.
• For better performance in case of moving shadow, the solar panels are on-grid and equipped with an optimizer. The technology is typically found in western countries.
