The people, the story and the instruments behind Retron Solar Diagnostics.

How we began, who leads the work, what we test with, and how to reach us. All on one page.

How we began

From training engineers to testing plants.

Retron Energies works across solar training and technical services. Retron Solar Diagnostics grew out of a simple observation: many plants have monitoring and maintenance, but few have independent measurement of what the plant really delivers.

Retron Energies was co-founded in January 2020 and is based in Patancheru, Telangana. Today it works across battery energy storage, EV centres of excellence, skill development and solar diagnostics.
