KELTRON is an empaneled channel partner for both grid-connected and off-grid solar systems by the Ministry of New and Renewable Energy (MNRE). It is also recognized as an empaneld agency for grid-connected solar projects by the Agency for New and Renewable Energy Research & Technology (ANERT).

The government of Kerala identified KELTRON as a nodal agency to implement solar power projects in the industries and local self-government departments. The solar division of KELTRON has so far executed 250 solar projects totaling 10 MW.

In June 2021, KELTRON invited bids to supply 1,604 multicrystalline solar modules of 330 W output for the 1 MW solar project at Ramakkalmedu in the Idukki district of Kerala.

Mercom had earlier reported that KELTRON floated a short-term expression of interest to empanel agencies and engineering, procurement, and construction contractors to install grid-interactive hybrid rooftop solar projects at different offices across Karnataka.
