What Is Off-Grid Solar System?
An off-grid solar system operates completely independently of the utility grid, storing all generated power in batteries for use whenever needed. Unlike on-grid or hybrid systems, there's no net metering and no grid export — the system must be sized to cover your full load from battery storage alone, making it larger and more expensive per kW than a grid-tied system of similar output.
Benefits of Off-Grid Solar System
Complete Independence
No dependency on grid availability at all, suited to locations without reliable grid access.
No Net Metering Needed
Since there's no grid connection, off-grid systems don't require DISCOM net metering approval.
Full Load Coverage
Sized to run your entire load from storage, not just backup essentials.
Suited to Remote Sites
A practical option for remote agricultural, farmhouse or under-served rural properties.
Battery Technology Choice
We size and recommend battery capacity and chemistry based on your actual load profile.
Scalable Storage
Battery banks can be sized up as your load requirements grow.
Is Off-Grid Right for You?
Off-grid makes sense mainly where grid connection is unavailable, unreliable beyond what a smaller backup battery could cover, or intentionally avoided. For the large majority of our Lucknow, Ayodhya and Kanpur customers with normal grid access, an on-grid or hybrid system is more cost-effective — we'll be upfront if off-grid isn't the right fit for your situation.
Up to \u20B91,08,000 Government Subsidy Available — as applicable under current Central + State benefits for eligible residential rooftop solar installations in Uttar Pradesh. Eligibility depends on system size, applicable government guidelines, approvals and scheme eligibility, and is subject to change.
Installation Process
Free Site Survey
We assess your roof, load pattern and existing electrical setup.
Design & Quotation
System size, component brand and itemised pricing are shared upfront.
Load & Battery Sizing
We calculate your full daily load requirement to size the battery bank and panel array correctly.
Installation
Panels, charge controller, battery bank and off-grid inverter are installed as a fully independent system.
Commissioning & Handover
System is tested, verified and warranty documents are handed over.
Why Choose Sunroof Solar Solutions
Because off-grid systems must cover 100% of your load from storage with no grid fallback, correct sizing is critical — our engineering team calculates this carefully rather than using a generic package size.
Frequently Asked Questions
The government subsidy discussed on this site applies to eligible grid-connected residential rooftop systems; off-grid systems generally fall outside standard net-metering-linked subsidy schemes — we'll confirm what, if anything, applies to your specific project.
Typically significantly larger and more expensive per kW, since it must include enough battery storage and panel capacity to cover your full load without any grid support.
Yes, if sized correctly for your load — unlike a battery backup on a hybrid system (usually sized for essentials only), an off-grid system is engineered to cover your complete daily consumption.
