OFF-GRID SOLAR
Power where the grid doesn't reach.
Battery-backed off-grid systems sized for 24/7 autonomous operation — for farms, remote residences, and any site with unreliable or absent grid access.
When off-grid is the right choice
No grid connection
Remote farms, forest outposts, tribal hamlets, and new construction sites without grid access.
Unreliable grid
Areas with 8+ hour daily outages where an on-grid system would be idle for most of the day.
Agricultural load
Irrigation pumps, cold storage, or poultry farms that need uninterrupted power independent of DISCOM.
Critical backup
Hospitals, clinics, telecom towers, or data centres where grid failure is unacceptable.
If you have a working grid connection, an on-grid system is almost always the better financial choice — you get subsidies, net metering income, and a lower upfront cost. Ask us to compare both options during your free survey.

-
No. PM Surya Ghar and the Odisha State subsidy apply only to grid-connected (on-grid) residential systems with net metering. Off-grid systems are not eligible. If your property has a grid connection, we strongly recommend on-grid first for the subsidy benefit.
-
Lithium iron phosphate (LiFePO₄) batteries are rated for 3,000–6,000 cycles, which typically translates to 8–12 years of daily cycling. Tubular lead-acid batteries last 5–7 years. We use LiFePO₄ for all new installations.
-
We size battery banks for 2–3 days of autonomy based on your load profile. Beyond that, a small diesel generator backup or a minimal grid connection (if feasible) is recommended. We design honestly — we will not promise coverage that the system cannot deliver.
-
Yes, if a grid connection becomes available. The solar panels and mounting are reusable. You would need a new grid-tied inverter and net meter installation. We design with this in mind when possible.
