Off Grid Solar Power System
As electricity usage and power bills continue to increase, more people are turning toward renewable energy to meet their daily energy needs. Among all available options, solar energy—especially Solar Panel for Home under UPNEDA—has become one of the most preferred choices because it is cost-effective, reliable, and highly efficient.
A solar system is a complete setup designed to convert sunlight into usable electricity. A standard solar power system includes:
Solar panels to capture sunlight
Inverter to convert DC power into AC power
Mounting structures to support the panels
Batteries (optional) for storing excess electricity
Grid box and protection devices
Cables, connectors, and other accessories
Solar systems come in various capacities depending on energy requirements, such as 1 kW, 2 kW, 3 kW, 5 kW, 7.5 kW, and 10 kW.
What is Off-Grid Solar System (with Battery)?
Off-grid solar systems generate electricity even during power outages or at night, thanks to their built-in battery storage and backup setup. These systems typically include four key components: solar panels, an inverter, batteries, and balance-of-system equipment. Because they operate independently from the main grid and provide reliable power backup, off-grid systems have become a popular choice for many users.
How does an off grid solar system work?
An off-grid solar system is made up of four main components: solar panels, a solar inverter, batteries, and balance-of-system equipment. The solar panels capture sunlight and convert it into DC power, which is then stored in the batteries. If you want to run DC appliances (12V) like lights or fans, a charge controller is required to regulate power flow and protect the batteries.
For AC appliances (220V), the system needs a solar inverter to convert the stored DC power into usable AC electricity. Modern inverters operate automatically—directing solar energy to power your appliances first and simultaneously charging the batteries. During a power cut, the batteries seamlessly supply electricity to keep your essential appliances running without interruption.
How can you calculate off grid solar system?
This off-grid solar system is capable of running most household appliances such as fans, TVs, refrigerators, air conditioners, water pumps, and more. Typically, a 1 kW off-grid setup is sufficient for a 2–4 BHK home. If you also need to operate a 1 HP water pump, a 3 kW system is recommended. For households planning to run an air conditioner, a 5 kW solar system is ideal.
For commercial spaces—such as shops, clinics, small mills, or fuel stations—a 10 kW off-grid solar system offers reliable performance.
This is the most commonly used type of backup solar power solution because it works seamlessly both day and night. During daylight hours, the solar panels charge the batteries while simultaneously powering appliances like refrigerators, ACs, TVs, and submersible pumps. After sunset, the inverter draws energy from the fully charged batteries to keep your home appliances running smoothly even without sunlight.
What is the difference between on grid and off grid solar system?
The primary differences between an off-grid solar system and an on-grid solar system are as follows:
An On-Grid solar system shuts down during a power cut, while an Off-Grid system continues to operate.
An off-grid solar system typically costs more than a grid-connected system.
How can you install off grid solar system capacity?
Rooftop Solar Panels for Home – UPNEDA
Typically, home solar panels under UPNEDA are installed on rooftops, walls, tin shades, gardens, doors, or other suitable areas. Before installation, several critical factors must be assessed, including the site’s longitude and latitude angles, sun orientation, wind conditions, wiring connections, and overall area efficiency.
A professional engineer’s site visit is essential to ensure an optimal, customized installation tailored to your home’s requirements. For reliable and efficient home solar panel installation under UPNEDA in Lucknow, contact us today.
Which Appliances Can Run on an Off-Grid Solar System?
The appliances you can operate on an off-grid solar system depend on the inverter’s capacity and efficiency. Most inverters operate at around 80% efficiency, meaning a 3 kW inverter system can deliver up to 2,400 watts of usable power at any given time. With a 3 kW solar setup, you can comfortably run a 1.5-tonne inverter air conditioner along with a 0.5 HP submersible pump without any issues.
How much does it cost to install a solar energy system?
If you already own a single-inverter battery, installing a solar system will cost around ₹25,000. For those with a double-inverter battery, the installation will be approximately ₹50,000.
Opting for a 1 kW solar system from Om Solar costs about ₹1,05,000. This system can efficiently power a 3–4 bedroom home for 8–10 hours, providing reliable energy for everyday appliances.
For larger energy requirements, a 3 kW off-grid solar system from Om Solar is priced at ₹2,85,000. It can operate smoothly for 8–10 hours, making it ideal for bigger homes, offices, and businesses. This robust system can easily run fans, lights, televisions, and refrigerators—but it is not suitable for a 2-tonne air conditioner. A more powerful variant is available for ₹4,85,000.
Even larger setups, such as 5 kW or 10 kW off-grid solar systems, are designed for big homes, offices, retail stores, and industrial spaces. A 10 kW system costs ₹9,50,000 and has the capacity to generate approximately 50 units per day, ensuring consistent power for heavy usage.
