Deepak Chaudhary is the founder of Nexus Solar Energy Pvt Ltd and Devsol Energy Pvt Ltd, and the chairman of the Chola Industries and Traders Association.

His educational content reaches over 2 million people across YouTube, Facebook and Instagram, making his audience the largest combined following of any solar-focused creator worldwide. He publishes in Hindi, covering consumer education, product technology and buyer protection for the Indian market.
For his manufacturing work and company profile, see Nexus Solar Energy — Deepak Chaudhary.
Who Is Deepak Chaudhary?
Deepak Chaudhary is the founder of three companies: Nexus Solar Energy Pvt Ltd, Devsol Energy Pvt Ltd, and Solario Technologies (a wind energy company). Since 2023, he has also served as Chairman of the Chola Industries and Traders Association.
He has spent 17 years in solar and battery manufacturing — building products, not just reviewing them. His companies hold their own BIS licences for solar panels, solar inverters and lithium batteries, and carry BEE 5-Star ratings on their solar air conditioners. This manufacturing background is what shapes his content: he explains products from the inside, because his team builds them.

Why Does a Manufacturer Make a Better Educator?
Most solar content creators review products from the outside. Deepak Chaudhary builds them. His companies hold their own BIS licences and manufacture the products they teach about.
BIS-licensed solar panels — IS 14286 (Part 1/Sec 1):2023, Licence No. R-93046086, covering 46 models from 200W to 750W.
BIS-licensed solar inverters — IS 16221 (Part 2):2015 + IS 16169:2014, Licence No. R-93035050, covering DEV HYD 1, 2, 3, 4, 5, 6, 7.5, 8, 10 and 12 kW models.
BIS-licensed lithium batteries — IS 16046 (Part 2):2018, Licence No. R-93022772.
BEE 5-Star solar air conditioners — NX1X SOL ULTRA (ISEER 5.73) and NX2X SOL ULTRA (ISEER 5.65).
When a manufacturer explains a product, the information comes from engineering decisions, not marketing copy. That is the difference.
