Project overview
A 2.4 MW building-integrated plant spread across the long-span roofs of an industrial complex in Dinajpur, North Bengal's largest single-site rooftop at the time of commissioning.
The plant feeds the complex's daytime process load directly and exports the surplus through net metering.
The challenge
The client wanted to cut a rising electricity bill without adding load to old roof purlins, and production could not stop during installation. North Bengal's winter fog and summer storms also had to be considered in the design.
Our solution
We carried out a structural check of every roof bay, then designed a lightweight rail system clamped to the existing metal sheets with no new penetrations into the purlins. Work was split into six zones so each could be built and connected during weekly maintenance shutdowns.
How it was delivered

Installation
Six zones installed over 8 weeks during planned shutdowns.
- 4
Commissioning
String tests, inverter start-up and utility inspection.
Results
- Installed capacity
- 2.4 MW
- Expected yearly generation
- ≈3.3 GWh
- CO2 avoided each year
- ≈2,000 t
