What is Off-Grid Solar?

Cut the Grid. Own Your Power.

An Off-Grid solar system has no connection to the electricity grid. Solar panels charge a battery bank during the day, and the batteries power your home or business at night and during cloudy periods. A charge controller and inverter manage the power flow.

Unlike On-Grid systems, Off-Grid works even when the utility grid fails — because there is no grid connection at all. It is the ultimate solution for remote locations, villages with no electricity, farms, resorts, and any location where grid power is unreliable or unavailable.

The battery bank is sized to provide 1–3 days of autonomy, meaning your system keeps working even without sunlight for multiple days.

Ideal Locations for Off-Grid Solar:

Remote villages & hamlets

Farms & agricultural land

Hills & tribal areas

Resorts & homestays

Construction sites

No-grid industrial units

Telecom towers

Disaster relief camps

Off-grid solar farm installation in a remote rural area

How Off-Grid Solar Works

Solar Panels Generate DC Power

Panels convert sunlight into DC electricity throughout the day.

Charge Controller Regulates Charging

MPPT controller safely charges the battery bank, preventing overcharge.

Batteries Store the Energy

Lithium or tubular batteries store power for nighttime and cloudy days.

Inverter Converts to AC Power

Pure sine wave inverter converts DC battery power to 230V AC for your appliances.

Why Off-Grid?

6 Reasons to Go Off-Grid

Off-grid solar panels in a vast rural green field

Zero Electricity Bills

No grid connection means no monthly electricity bill. Your only cost is the one-time system investment.

Complete Power Independence

Never depend on DISCOM, load-shedding schedules, or grid failures again. You control your own power.

Replace Diesel Generator

Save ₹15,000–₹40,000/month in diesel costs. No noise, no fumes, no fuel logistics to manage.

Works Anywhere in India

No grid infrastructure needed. Deploy in remote hills, forests, islands, or areas where grid extension is not feasible.

1–3 Days Battery Autonomy

Properly sized battery bank provides power through consecutive cloudy days without any grid backup.

25-Year System Life

Solar panels last 25+ years. Lithium batteries 10–15 years. Long-term investment with minimal ongoing costs.

Battery Storage

Choose Your Battery Technology

We offer both Lithium Iron Phosphate (LiFePO4) and Lead-Acid Tubular batteries depending on your budget and application.

FAQs

Common Questions

What happens when there is no sunlight for many days?

The battery bank is sized to provide 1–3 days of autonomy even without solar generation. For longer monsoon periods, we recommend a diesel generator as a backup charger (connected to the battery via a charger, not the load), which you would use only rarely.

Can I run an air conditioner on an off-grid system?

Yes. We size the system accordingly. A 1.5-ton AC typically needs a 5 kW system with a 10 kWh battery to run for 8 hours daily. System size and cost increases significantly with AC load — we always recommend energy-efficient 5-star inverter ACs.

How long do the batteries last?

Lithium LiFePO4 batteries last 10–15 years (4000+ cycles at 80% DoD). Tubular lead-acid batteries last 5–7 years (1200–1500 cycles at 50% DoD). We recommend lithium for long-term savings despite higher upfront cost.

Is there any government subsidy for off-grid solar?

PM Surya Ghar Yojana subsidy applies only to On-Grid (grid-connected) systems. However, PM-KUSUM component-A supports off-grid solar pumps for farmers. For general off-grid homes and businesses, no central subsidy is currently available, but some states offer their own schemes.

What is the difference between Off-Grid and Hybrid?

Off-Grid has NO grid connection at all — it is 100% self-sufficient. Hybrid has BOTH battery storage AND grid connection — it uses batteries first, then grid, and can export excess to the grid. If your area has a grid connection and you mainly want backup power, Hybrid is usually a better choice.

Can I upgrade my off-grid system later?

Yes, within limits. You can add more solar panels if your charge controller and battery bank have headroom. Adding more battery capacity is usually straightforward. Major upgrades (different voltage system) require replacing core components. We design systems with future expansion in mind.
