What Is an
Off-Grid Solar System?
An off-grid solar system is a standalone solar power setup that works completely independently of the electricity grid. Solar panels generate power during the day, a charge controller stores it in batteries, and an inverter converts it into usable AC power for your home, farm or business, day and night.
Unlike grid-connected solar systems, an off-grid setup includes battery storage to store excess solar energy for use when sunlight is unavailable. This makes it suitable for locations where grid electricity is unavailable, unreliable, or affected by frequent power cuts.
Off-grid solar systems can provide dependable power for homes, farms, shops, businesses and remote locations while reducing dependence on conventional electricity and diesel generators.

How an Off-Grid Solar System Works
An off-grid solar system uses solar panels, a charge controller, battery storage and an inverter to generate, store and supply electricity without depending on the conventional power grid.
Solar Panels
Mono PERC or TOPCon solar panels convert sunlight into DC electricity for the off-grid system.
Charge Controller
MPPT or PWM charge controllers regulate battery charging and help protect the battery from overcharging.
Battery Bank
Tubular lead-acid or lithium LiFePO4 batteries store solar energy for night-time and cloudy days.
Off-Grid Inverter
The off-grid inverter converts stored DC electricity into 230V AC power for household and commercial appliances.
Mounting & Cabling
Proper mounting structures and correctly sized cabling help connect the solar panels and electrical equipment safely.
Earthing & Lightning Protection
Earthing, protection devices and lightning arresters help improve electrical safety and protect the system from electrical faults and surges.
On-Grid vs Off-Grid vs Hybrid Solar System
Compare on-grid, off-grid and hybrid solar systems based on grid connection, battery backup, outage support, net metering and typical use cases.
| Feature | On-Grid | Off-Grid | Hybrid |
|---|---|---|---|
| Grid connection | Required | Not needed | Yes |
| Battery | No | Yes | Yes |
| Power during outages | No | Yes | Yes |
| Net metering | Yes | No | Yes |
| Relative cost | Lowest | Higher (battery) | Highest |
| Best for | Stable-grid cities | Remote or no-grid areas | Frequent power cuts + bill savings |
Off-Grid Solar System Price in India (2026)

Which Battery Is Right for Your Off-Grid System?
Battery technology plays an important role in backup duration, maintenance, system life and overall cost. Compare the two commonly used battery options for off-grid solar systems.
Traditional Option
Tubular Lead-Acid
Lower upfront cost and widely serviced, but needs water top-up and typically lasts 4–6 years.
Long-Term Option
Lithium (LiFePO4)
Higher upfront cost, but maintenance-free, lighter, allows deeper discharge and usually lasts 10+ years, which often makes it cheaper over the system's life.
Choose the battery based on your backup requirement, daily energy usage, available space, maintenance preference and expected system life. A verified installer can help size the battery correctly for your off-grid solar system.
Who Should Choose Off-Grid Solar?
Off-grid solar systems are suitable for locations where grid electricity is unavailable, unreliable or where dependable backup power is required.
Farmhouses & Orchards
Reliable solar power for farmhouses, orchards and agricultural locations with limited or unreliable grid electricity.
Homes in Villages
Suitable for homes in villages and rural areas with weak, unreliable or no grid electricity supply.
Hill-Station Homestays
Useful for homestays in Uttarakhand, Himachal Pradesh and North-East India where reliable grid access may be limited.
Telecom & CCTV Sites
Keep telecom towers, surveillance systems and remote CCTV sites powered without depending entirely on the grid.
Rural Schools & Health Centres
Support essential electricity needs in rural schools and primary health centres where reliable grid supply is limited.
Poultry & Dairy Units
Provide dependable electricity for lighting, ventilation, cooling, pumps and other essential farm operations.
Diesel Generator Replacement
Consider off-grid solar when you want to reduce dependence on diesel generators for regular power requirements.
Remote Worksites & Construction Sites
Reliable off-grid power for construction sites, temporary workspaces and remote locations where grid electricity is unavailable or limited.
Government Subsidy for Off-Grid Solar
Subsidy eligibility depends on the type of solar system, application, location and applicable government scheme. Off-grid systems should not be assumed to qualify for the same subsidy available for grid-connected rooftop solar.
Check the Applicable Scheme Before Claiming a Subsidy
PM Surya Ghar Muft Bijli Yojana subsidy applies to eligible grid-connected rooftop solar systems . Standard standalone off-grid home systems are therefore generally not covered under this rooftop solar subsidy.
For farmers, PM-KUSUM Component B supports standalone solar agricultural pumps in eligible off-grid areas, subject to the applicable scheme conditions and implementation by the designated state agencies.
Some state renewable energy agencies may also run schemes or programmes for specific off-grid, agricultural or remote-area applications. Eligibility, availability and financial support can vary by state and scheme.
Before purchasing an off-grid system, ask your UrjaOne vendor to verify the current scheme, eligibility and applicable support for your state.

ऑफ-ग्रिड सोलर सिस्टम क्या है?
ऑफ-ग्रिड सोलर सिस्टम ऐसा सोलर पावर सिस्टम है जो बिजली के मुख्य ग्रिड पर निर्भर नहीं रहता। इसमें सोलर पैनल, इन्वर्टर और बैटरी का उपयोग करके दिन में सौर ऊर्जा से बिजली बनाई जाती है और अतिरिक्त ऊर्जा बैटरी में स्टोर की जाती है, ताकि जरूरत के समय बिजली उपलब्ध रहे। भारत में ऑफ-ग्रिड सोलर सिस्टम की कीमत आमतौर पर सिस्टम की क्षमता, बैटरी के प्रकार, पैनल, इन्वर्टर और इंस्टॉलेशन के आधार पर लगभग ₹1 लाख से ₹5 लाख या उससे अधिक हो सकती है। यह उन घरों, फार्महाउस, ग्रामीण क्षेत्रों, दूरदराज के स्थानों और ऐसे व्यवसायों के लिए उपयोगी हो सकता है जहां ग्रिड बिजली उपलब्ध नहीं है या बैकअप की आवश्यकता अधिक है। सही सिस्टम चुनने से पहले लोड, दैनिक बिजली खपत और बैटरी बैकअप की जरूरत का आकलन करना जरूरी है।
