Project Description

Project Gallery

Koramangala, Bangalore

This installation is located  in the commercial hub of Bangalore at Koramangala. To reduce the commercial Paying Guest accommodation electricity bills and also to reduce his carbon footprint, our client installed a 7 kWp Solar Roof-Top On-Grid System helping him to make his electricity bills zero. The system is designed to generate on an average 28 units per day. At a BESCOM rate of Rs.10 per unit, the system is designed to save our client ~Rs.250.00 per day.

The system is installed with 19 numbers of Mono-Crystalline Solar Panels from Waaree and 19 numbers of Micro-Inverters from Enphase. Since the roof had shadow issues from the water tank on the south-west side, the panels were installed on an elevated corrugated sheet structure to negate the effect of shadows. The elevated structure was designed to serve the dual purpose of having a space for roof-top garden below the solar panels and also for the Yoga Sessions of our client. An elevated MS Structure with Saw-Tooth design with walk-ways in between is designed and implemented at the site.

Designing the System

The main requirements of the customer while designing the system were:

  • Elevated structure with corrugated sheet and  easiness for cleaning of panels
  • Good Remote Monitoring UI with per panel generation
  • System should generate ~25 units per day with excess power sent back to the grid in the morning half under net-metering.

Solar Panels: With the intention of generating 10-11 units per day, 19 numbers of 370Wp MonoCystalline Panels were chosen for this installation. The panels are manufactured by Indian Solar Panel Manufacturer Waaree . From our experience, a 1kWp Solar Power Plant in Bangalore generates on an average 4 units per day on an yearly basis- Considering this thumb rule a 7kWp System was deemed fit for generating 27-28 units per day.

Solar Inverter: With the intention of scaling up the system at a later stage and also to provide maximum transparency to the system for our client, we suggested Micro-Inverters from Enphase . Micro-Inverters provide an added advantage of better performance with shadows, scalability to the system and also an excellent Remote Monitoring UI which helps the customer as well as EcoSoch Team to keep a track of the generation on a daily basis. Enphase Micro-Inverters makes it easy for our client to maintain his system- our client schedules his cleaning of solar panels based on the generation output he views in his remote monitoring mobile application everyday.

Since the Micro-Inverters are installed with each panel, we did not have to worry about finding a space for placement of inverter nor about the DC Cable routing. Micro-Inverters converts the DC of Solar Panel to AC at each panel level.

Mounting Structures: The panels has a warranty of 25 years and the Enphase Micro-Inverters has a warranty of 10 years with a design life of 25 years. In order to ensure that the system lasts for 25 years, special care is put into the installation of solar panels on the Corrugated sheet structure. Aluminum Structure which is practically rust resistant are used for solar panel installation.

At the end, our client was happy that the got a system catering to his initial requirements and also a system which is well engineered to last for more than 25 years.
