A chronicle · written by a former associate
Inside India's inverter industry —
before the headlines.
It did not begin with an inverter. Su-Kam started in 1988 — cable TV on Delhi rooftops. A decade later, a broken inverter and a technician’s insult turned wounded pride into an industry. The same arc is told in first person at solarmanofindia.com; this site is the version that did not make the magazines.

What happened to Su-Kam
