Solar Microgrids

Tata Power Solar as India's largest integrated solar solutions provider has rightfully earned the title on their core mantra of always maintaining the project timelines and executing within tight budgets. Always the first choice for the Government agencies when it comes to executing solar power projects, Tata Power Solar's unwavering commitment to the core values continue to lead and pave the way to harnessing the power of sun and enabling solar energy in the remotest of locations across India.

The local renewable energy agencies and MNRE recognized the villages that were devoid of any sustainable source of energy, partnered with Tata Power Solar to design solar power project that powered over 100 villages where grid connectivity was next to impossible.

To solarize these many villages sprouting between Leh and Ladakh spread over a wide region, posed an enormous gamut of challenges due to the weather, altitude and topography of the region.


Empowering the tribal communities in Chhattisgarh


Tata Power Solar’s journey of enabling solar everywhere is incomplete without the chapter on Chhattisgarh. Located centrally in the dense forests of Chhattisgarh, the tribal community here continues to be a very isolated one that is rendered unreachable due to the lack of infrastructure. For an extended period of time, this place has continued to remain removed from the rest of civilization and all the while these tribal communities have been deprived of basic necessities with absolutely no access to power.

Tata Power Solar, as part of the projects outlined above, has set up over 100 microgrids solar systems in a phased approach across the many villages spanning the Chhattisgarh forests.

This project has posed many challenges such as the accessibility of these villages, acceptance by local community which Tata Power Solar was able to preemptively account for and solve. This has made this particular project a huge success and changed lives of the people in Chhattisgarh. Today it is a tale to tell.

Tata Power Solar continues to enthrall communities with extensive expertise in microgrids projects in India that are remote and terrains that pose profound challenges. Sundarbans is yet another success story of seamless planning and smart execution by Tata Power Solar with strict adherence to agreed budgets and allotted timeline.

Travelling from Howrah for 81 kms taking a 90 minutes ferry ride from Patharpratima, is what takes one to the beautiful village of Indrapur, in Sundarbans which leaves you spellbound.


Tata Power Solar successfully custom designed, engineered and installed a 110 kW solar plant that was commissioned in March 2011. The grid matches the average sunlight that the village gets 1 bright day followed by 1 cloudy day. Tata Power Solar has skillfully designed a solar powered grid that is simple, easy to use & maintain and manages to do all this at a very low cost of implementation. For a community that is remote and removed from civilization, Tata Power Solar has successfully provided Indrapur an economically viable and sustainable source of energy.

India's highest telescope powered by Tata Power Solar


The tough terrain of Ladakh is like a second home for Tata Power Solar. The company has successfully commissioned the maximum number of large, standalone power plant installations in this region including a 40 kWp plant at Nuyoma, 100 kWp plants at Durbukand and a 35 kWp plant at Hanley. The project at Hanley featured here is the second project being commissioned by Tata Power Solar for the same client at the same location which reflects customer confidence in Tata Power Solar’s expertise in such difficult terrains.

Indian Institute of Astrophysics (IIAP), Bangalore wanted Tata Power Solar to build a 35 kWp solar plant at the IIAP Observatory at Hanley, Leh to power India’s highest telescope.


This project is unique for its location, the purpose for which it was built reflects Tata Power Solar team’s capabilities to account for complexities that arise due to altitude as well as the end application it supports.
