Long before Indian industry understood what YouTube was for, Kunwer Sachdev was building a free technical curriculum on it. I was inside Su-Kam when he created the Su-Kam Solar channel — and the 167 videos it would eventually carry — at a time when the rest of the Indian power-backup and electrical industry was not making training content about solar at all.
The channel still lives at youtube.com/@sukam. It has not been updated in years. The green-and-yellow branding is from another era. But the timestamps on those uploads are unchallengeable: most went up eight or nine years ago, when the Indian solar industry was, by any honest measure, still a niche — a government aspiration, a topic at conferences, something informed people discussed at the margins of a market dominated by diesel generators and lead-acid inverters. The channel nobody watched, back then, is quietly one of the more significant records of who was building India’s solar knowledge base before there was a solar industry to speak of.
In Kunwer Sachdev’s own words, here is why the channel was built:
A Free, Technical Curriculum
The videos are technical. Not glossy, not produced for a general audience, not the kind of content that chases views with titles optimised for the algorithm. They explain how a 50kW off-grid rooftop solar system works. They walk through charge controller configurations. They introduce UPS products and demonstrate how solar PCUs integrate with battery banks. They are the kind of videos that an installer in a Tier 2 city, trying to understand a technology that had almost no local training infrastructure, could actually learn something from.
That was the point.
There was no established installer community of the scale that exists today. There were no courses, no YouTube ecosystems, no widely available technical resources for the people who would eventually become India’s rooftop solar workforce. What existed, from Su-Kam, was this channel — built because he understood digital media before almost anyone else in the sector did.
It was not primarily a marketing exercise, though it served that function too. The instinct behind it was more specific: Kunwer understood that for a new technology to become a business, the people who install and service it need to know how it works. The customer might be convinced by a salesperson. The dealer might be convinced by a margin. But the technician who arrives at someone’s house to mount the panel and wire the PCU — that person needs actual knowledge. And in 2015, 2016, that knowledge was scarce.
He decided to put it on YouTube and make it free.
A representative training clip from the archive — a 50kW off-grid rooftop system explained for installers:
An Organised Library, Not a Brand Channel
What the channel eventually became is visible in its structure. This was not a collection of loosely assembled videos — it was an organised library. A dedicated Solar Solutions playlist ran to 92 videos. A Kunwer Sachdev playlist of 24 videos documented his thinking and public appearances directly. Su-Kam on TV archived 20 media appearances. A service playlist ran to 28 videos for technicians in the field.
And then the Feature Sets — two structured series covering topics that read, in 2026, like a basic solar literacy curriculum: ATC Automatic Temperature Compensation, Low Voltage Disconnect, 90 Volt Low Voltage Charging, Variable Battery Charge, What is a UPS, How to Choose a Solar Inverter, 6 Stage Charging, Charge Sharing, What is Solar Online UPS, Dip Switch Setting, Fuse and MCB, How Many Appliances Can You Run.
Each topic is a playlist. Each playlist is multiple videos. This is not a brand channel. This is a structured curriculum, produced at a time when most companies in the Indian power sector were still figuring out what a YouTube channel was for.
One of the Solar Solutions playlists documented real installations across India:
Built Before the Market Existed
The India that existed when those videos were uploaded is worth holding in mind. Rooftop solar installations were measured in single-digit gigawatts nationally. The PM Kusum scheme and the aggressive state-level bidding that would later transform the landscape were still in the future. For most Indian consumers and most Indian installers, solar was something that happened in large parks in Rajasthan, not on the roof of a shop or a hospital or a home.
Into that moment, Kunwer placed 167 videos explaining how the technology worked.
There is a particular kind of market-building that does not show up on a balance sheet and does not get credited in the standard accounts of an industry’s growth. It is the education of the people at the edge of the ecosystem — the installers, the dealers, the small contractors who will carry a new technology into the real economy. They are not the customers. They are not the investors. But without them, nothing scales.
The Su-Kam Solar channel was aimed at precisely those people. It was, in retrospect, an investment in the infrastructure of a market that did not yet fully exist.
The storytelling on the channel reached beyond product explainers — Su-Kam’s solar work was later featured in Sun Fuel, a Discovery Channel documentary on Indian solar:
The channel sits dormant now. Su-Kam’s chapter closed. The green-and-yellow branding is from another era. But the videos remain. And they carry a timestamp that is more precise than any claim that could be made in a press release or a founder’s biography. Eight years ago, nine years ago — dates embedded in the metadata of the platform, unchanged and unchallengeable — Kunwer Sachdev was making solar training content for the Indian market when making solar training content for the Indian market was not something the Indian market was asking for.
The solar industry that exists in India in 2026 — with its rooftop mandates, its BESS tenders, its armies of trained installers and certified electricians — did not emerge from nowhere. It was built, in part, by people who invested in educating it before it was ready to be educated.
That channel is one piece of evidence about who was doing that work, and when.
Those of us who worked with him would recognise the same instinct in his later ventures — different era, different platform, different products, same understanding of what it takes to build something that lasts.
The channel nobody watched turns out to have been watched, in the end, by exactly the industry it was made for.
The fuller story of how and why this channel was built is told in the first YouTube channel in India’s solar industry, and the broader arc in how Kunwer Sachdev sparked a solar movement in India.
