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.

[mk_fancy_title color=”#464646″ size=”20″ font_weight=”500″ margin_bottom=”0″ font_family=”none”]About the project[/mk_fancy_title]

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.

[mk_fancy_title color=”#464646″ size=”20″ font_weight=”500″ margin_bottom=”0″ font_family=”none”]About Church of South India[/mk_fancy_title]

The Church of South India (CSI) is the second largest Christian church in India based on the number of members and is result of union of Anglican and number of Protestant churches in South India.

The Church of South India is the successor of a number of Anglican and Protestant denominations in India, including the Church of England, the British Methodist Church and the Church of Scotland after Indian Independence.

The CSI synod consists of bishops of 24 dioceses, presbyters and layman (both men and women) who are elected from the respective diocesan councils to the synod. The synod members will elect the apex body consisting of a Moderator, Deputy Moderator, general secretary and Treasurer. The Moderator is the spiritual and administrative head of the Church.

[mk_fancy_title color=”#464646″ size=”20″ font_weight=”500″ margin_bottom=”0″ font_family=”none”]Why Solar[/mk_fancy_title]

With a lot of visitors coming to be part of the church proceedings the guest house in CSI Synod is mostly full. With increasing visitors, building consumption is constantly increasing resulting in high electricity bills.

CSI Synod had decided on solar rooftop system while wondering about solving the high electricity bills.  They had approached Sunlit Future to install rooftop solar grid-tied systems on the guest house. It also inspires the visitors to consider sustainable solutions.

[mk_fancy_title color=”#464646″ size=”20″ font_weight=”500″ margin_bottom=”0″ font_family=”none”]About the project[/mk_fancy_title]

A total of 100.56kW solar rooftop system was installed on the rooftop of the CSI-Synod.

CSI Synod had decided to go for the SolarEdge power optimizers and inverters rather than traditional string inverters to have a higher solar yield and greater savings.

These products aim to increase energy output through module-level Maximum Power Point Tracking (MPPT) and also provide module-level remote monitoring via the SolarEdge monitoring web portal and mobile app.

Complete system was connected with help of a Modbus meter which enables zero export option. As the building have equally high day time loads, they have considered to use Modbus meter till they get a bidirectional meter from the utility grid company.

It also captures the load of the complete building which helps in finding out the consumption patterns of the building.

Aravind Eye Care Hospitals chain emerged from Dr Govindappa Venkataswamy’s mission to eliminate the needless blindness of the people. Founded in Madurai, Tamil Nadu with 11 bed hospital, Aravind eye care emerged with more than 4000 beds. Aravind Eye Care treated more than 56 million people from its inception.

From Madurai, Aravind eye hospital expanded to TirupurSalemDindigulThoothukudiUdumalaipettai , Tirupati and neighboring Pondicherry.

Adding to the mission, Aravind Eye Care hospital in Puducherry had gone for a 201 kWp solar PV system on its rooftop to cater to the continuous energy consumption of the hospital in a sustainable way.

[mk_fancy_title color=”#464646″ size=”20″ font_weight=”500″ margin_bottom=”0″ font_family=”none”]Why Solar[/mk_fancy_title]

With continuous inpatients and huge number of surgeries taking place round the clock, the hospital is contributing to huge electricity consumption. Due to which, they are incurring huge electricity bills and dependent on fossil fuels for that.

Inorder to decrease the electricity bills and contribute towards sustainable way of power generation, Aravind Eye Care hospital in Puducherry had gone for a 201 kWp solar PV system on its rooftop. 

The project was carried out in two phases with 136 kWp in Phase I and 64.6 kWp in Phase II, making it a 201.28 kWp capacity in total.
