Residential Rooftop On-Grid
Net metering with WBSEDCL
Your roof generates through the day and exports the surplus to the WBSEDCL grid. A bi-directional meter counts what you export against what you import, and you are billed only on the difference.

Hybrid Solar + Energy Storage
Zero load-shedding, day or night
A hybrid inverter runs your home on solar, charges a battery bank with the surplus, and switches over the instant the grid fails. Your fans, lights, TV, Wi-Fi and fridge simply keep running.
Instant changeover
No flicker, no reset — sensitive electronics stay on.
Tubular or lithium bank
Tubular for value and long life; lithium for compact size and fast charging.
Sized to your load
We measure the exact appliances you want backed up, and for how many hours.
Solar-first charging
The battery charges from the sun before it ever touches grid power.

Cold storage units
Offsets the compressor load that drives your bill through the summer.
Shallow tube-wells
Solar pumps for 2 HP – 5 HP irrigation, with or without grid support.
Commercial documentation
Sanctioned-load paperwork and WBSEDCL LT/HT coordination handled.
