Brigade Millennium Jacaranda Apartment, JP Nagar, Bengaluru
About Brigade Millennium Jacaranda Apartment Project
BRIGADE MILLENNIUM JACARANDA, a 14 storied apartment community in the midst of Bangalore went with a 49.9 kWp solar rooftop system to take care of their common electrical loads in the building. With more than 60 flats in the apartment complex, having elevators running all the time, there is a huge requirement of energy.
The main aim of installing solar is to let down the electric bills as apartments are consume a lot of energy in common areas which can’t be avoided.
REC half cut modules were used along with Enphase microinverter technology in this system.
With micro inverter technology, each panel generates power independently unlike the string inverter technology, the dc power is converted to ac straight under the panel with help of microinverter fixed below it. This helps in reducing the risk of high DC voltages. With multiple raised structures on the rooftop, this technology helps in enhancing the generation of the system.
System being installed on the top of 14 storied buildings, there is a Prefabricated aluminium structure used in this project. Prefabricated ballast structures are plug and play type where grouting into the rooftop is completely avoided which will not let any possibility for water leakages in the roof. Aluminium is free from rust and has good resistance to corrosion helping the system stay healthy for long.
high chance of heavy wind. In order to minimize the effect of the wind below the panels, panels were installed in such a way that they stay to close to the rooftop reducing the wind circulation below the modules.
This total system with 49.7Kw will generate more than 76 thousand units per annum on an average. Considering the average cost per unit as Rs.8 the total savings per year will be more than 6 lakhs. With more than 20 years of life, this system pays back the investment in around 4 years.
At the same time, for this generation this system reduces 1.5lakh metric tonnes of CO2 and is also equivalent to reducing more than 90 thousand litres of petrol per annum
