Alcove New Kolkata, an Alcove Realty township project in Seramopore, Hooghly is a high-end residential society on the banks of the serene River Ganga. Alcove provides a wide range of modern-day amenities with its flats in New Kolkata, Serampore, including common area lighting, community halls, lifts, surveillance systems, wastewater treatment plants, parking areas, underpass lighting, communication towers, gardens, and high-tech gyms.
This Alcove Realty project not only connects its residents with nature with its fountains and gardens but also steps forward to conserve it by installing one 31.5 KWp solar rooftop power plant on each of its six towers. Alcove chose SunShell Power as its solar partner to install solar power plants that helped in reducing electricity bills and its carbon footprint.
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.
