Sri Sarada Ashram was established with the core objectives of promoting and developing the poor and the backward villages by means of quality education, affordable healthcare, cultural and socio-economic development activities, agricultural development and providing much needy and timely relief during natural disasters.

Located at Uludurpet, on the Chennai Trichy Highway in Tamilnadu, the Ashram houses 45 Sanyasin Sisters and services the remotest villages in and around the place. Over 1000 students and 500 women are given schooling, vocational training and job-oriented career coaching annually.

Contributing towards the sustainable future with various initiatives in ashram, they had decided to add more to it. With regular training to the women in ashram, kids in the school there is a need of energy demand. Inorder to reduce the electricity bills and promote renewable energy, ashram decided to go ahead and install solar on its rooftops.

A total of 63.28kWp of Solar rooftop system was installed on five different buildings using SolarEdge power optimizer technology. These buildings include main ashram building, boys hostel, pump house.

A 10kW solar rooftop system was installed earlier on one of the buildings by another vendor. Due to performance issues, revamp of the system was needed. Sunlit future had revamped the system and extended the system to 17kW with SolarEdge power optimizers technology. Existing 240Watt panels for 10kW and 7kW of 360Watt panels under one inverter were connected. This gives an affirmation that the system could be extended in future with no extra investment on inverter.

Satisfied with the performance of the revamped system, ashram authorities had reached us for solar on other buildings as well, extending it to 63.2kW

SolarEdge Power optimizer technology enhances the generation of each of these systems. They have module level MPPT which enhances the generation. Overall performance of the system is not compromised with shade on one module due to the trees or dust or bird droppings.

This system was installed with Modbus meter enabling Net Zero option. All the generation of each of the systems is being utilized in the building and there is no excess generation that gets exported to the grid.

It saves about Rupees 52,000/month at an average with the generation. All the systems together takes about 5 years for the return of the investment.

Solar on all the five buildings was installed on the flat roof with the help of pre fabricated cement ballast structure made of Aluminium. This structure helps in corrossion free and long durability of the system.

Safe walkways were provided ensuring seamless maintenance of the system. Cables were routed through UPVC pipes providing safety from external factors like weather, insects etc.
