Off Grid Solar System: Prices, Subsidy, ROI & Working
Tired of unpredictable power cuts? Living in a location where the grid just doesn’t reach? Imagine a life where you are completely in control of your electricity, free from the whims of the utility company. That’s the promise of an off-grid solar system, and at Solarva, we’re here to make that a reality for you.
An off-grid solar system, also known as a standalone power system, is your ticket to energy independence. It’s a self-sufficient powerhouse that generates, stores, and supplies all the electricity you need, without any connection to the main grid. This makes it the ideal solution for remote homes, farms, cabins, or anyone who values a reliable, uninterrupted power supply.
An off-grid system is an integrated solution that works together to deliver power day and night. The key components include:
- Solar Panels (Modules): These are the heart of the system. They capture sunlight and convert it into direct current (DC) electricity.
- Batteries: This is the most crucial component of an off-grid system. The batteries store the excess energy generated by your panels during the day, providing a power reserve for nighttime, cloudy days, or emergencies.
- Solar Inverter: The inverter’s job is to convert the DC electricity from your panels and batteries into alternating current (AC) electricity, which is what all your household appliances and electronics use.
- Charge Controller: This smart device regulates the flow of electricity from the solar panels to the batteries, preventing overcharging and protecting the lifespan of your battery bank.
- Mounting Structures: These structures securely hold the panels in place at the optimal angle to capture the maximum amount of sunlight throughout the day.
- Safety Accessories: A complete system includes essential accessories like cables, combiner boxes, and lightning arresters to ensure the safety and longevity of your investment.

The process is a simple, elegant cycle of energy generation and storage:
- Solar panels absorb sunlight and convert it into DC electricity.
- This DC electricity flows through a charge controller, which directs the power.
- The charge controller sends power to the off-grid inverter to run your home’s appliances.
- Any surplus power is then stored in the battery bank for later use.
- At night or when sunlight is limited, the inverter draws power from the batteries to keep your home running smoothly.
- Solar panels absorb sunlight and convert it into DC electricity.
- Complete Energy Independence: Say goodbye to monthly electricity bills and rising energy costs. With an off-grid system, you are your own power company.
- Uninterrupted Power: Never worry about power outages again. Your system provides a continuous, reliable power supply, even when the rest of the grid is down.
- Power for Remote Locations: An off-grid system is the perfect and often only solution for powering homes and businesses in rural or remote areas where extending the grid is not feasible.
- Environmental Impact: By generating your own clean, renewable energy, you significantly reduce your carbon footprint and contribute to a healthier planet.
While an off-grid system requires a larger upfront investment due to the cost of batteries, the long-term savings and peace of mind it provides are invaluable. The system typically pays for itself within 6-7 years through the elimination of electricity bills and the savings on diesel generators.

1. What is the main difference between an on-grid and an off-grid solar system?
An on-grid system is connected to the public utility grid. It relies on the grid for power at night or on cloudy days and can send excess electricity back to the grid for credits through a process called net metering. An off-grid system, on the other hand, is completely independent. It uses batteries to store solar energy, providing you with power 24/7 without any connection to the utility company.
2. How much does an off-grid solar system cost in India?
The cost of an off-grid system varies widely based on your energy needs and the components you choose. A typical 1 kW system, including batteries and installation, can range from ₹85,000 to ₹1,05,000. Larger systems, such as a 10 kW system for a larger home or business, can cost ₹7 lakhs or more. While the initial investment is higher than an on-grid system, you save money in the long run by eliminating your monthly electricity bills.
3. Is there a government subsidy for off-grid solar systems?
Currently, the central government's PM Surya Ghar Muft Bijli Yojana offers subsidies primarily for residential on-grid solar systems. However, some state-level programs or specific schemes for remote and rural areas might offer incentives. It's best to consult with our solar experts to learn about any available subsidies that may apply to your location and project.
4. How long do the batteries in an off-grid system last?
Battery life depends on the type, usage, and maintenance. Lead-acid batteries typically last 5-7 years, while advanced lithium-ion batteries can last 10-15 years or more. We offer a range of battery options and will help you choose the best fit for your needs and budget.
5. What happens during a prolonged period of cloudy or rainy weather?
Off-grid systems are designed with a certain number of "autonomy days" to handle periods with low sunlight. During these times, your system will rely on the energy stored in your battery bank. If you anticipate a need for power beyond your battery's capacity, we can help you integrate a backup generator to ensure an uninterrupted power supply.
6. Can I expand my off-grid system in the future?
Yes, off-grid systems are scalable. As your energy needs grow, you can easily add more solar panels and batteries to increase your system's capacity. We always recommend planning for potential future expansions during the initial design phase to ensure seamless integration.
