Net Zero Energy Building (NZEB)

Act Three: Integration of a large capacity energy storage system, the Cellcube FB 10-100. In addition to its ability to store upto 100 kWh of energy per unit, it also functions as an effective energy management system. Excess energy produced during the day by the SC 260 is stored in the Cellcube, which in turn supplies energy during the night hours, and during monsson days when the sun does not shine.

Based upon the sizing for the ORBPL energy plan, the system was configured with 2 units of SunCarrier SC 260, with an overall rating of 67 kWp, for a planned yield of over 130,000 kWh per annum. 3 units of Cellcube FB 10-100, each with a maximum power rating of 15 kW, and a storage capacity of 100 kWh, were configured. 1 SMA Multi-cluster box completed the configuration.

The system described above has a design life of 25 years. The SunCarrier SC 260 require minimal maintenance in terms of periodic cleaning the dust off the PV module surfaces. The PLC controls and monitoring systems incorporated both in the SunCarrier SC 260 and the Cellcube FB 10-100 allow remote monitoring of critical performance parameters and take the rarely required preventive actions to ensure smooth functioning of the system. The systems are highly eco-friendly in that they are over 95% recyclable, emit no harmful gases or effluents, and there are no heavy metals to dispose off.

Act Four:

The ORBPL Net Zero Energy Building
The ORBPL Net Zero Energy Building (NZEB), located in the central part of India, in the city of Bhopal, the capital of Madhya Pradesh, is an example of how organisations that can, go beyond adopting the best in energy conservation technologies, and augment the energy supply by implementing 'green' energy systems that leverage nature's abundance of solar energy.
