OFF-Grid Solar System

An off-grid solar system (solar roof-top system with battery bank) is a system that works completely independently of the utility grid. This means that any excess or deficiency of power cannot be fed to or drawn from the grid through net metering. Instead, all excess power generated is fed directly into the batteries connected with the system. Many residential and commercial users are opting for an off-grid solar system as they get a chance to enjoy self-generated electricity, break free from relying on the discom/grid, and heavily cut down their electricity bills by running appliances on their own stored power. You will always have power directly from the solar system or your dedicated batteries.

How Off-Grid System Works?

In an off-grid solar system, solar panels produce power during the day. This power can either be used instantly to run your active loads or exported to the batteries to store as backup for nighttime use and power outages. Since this system does not rely on the grid, you produce, store, and manage 100% of your energy internally. Any excess electricity produced during peak sunlight hours is channeled directly into the connected battery bank to keep them fully charged.

The primary advantage of an off-grid system is that the user has complete energy independence with their own self-generated electricity. Because you do not rely on discom or grid lines, you never have to face the stress of rising electricity rates or sudden regional power cuts.

Important Notice: Always assess your home's energy consumption & solar electricity needs carefully before installing an off-grid solar system to ensure your battery capacity matches your structural load.

The light from the sun falls on the solar panels from where DC electricity is generated. This DC from the sun is converted into AC with the help of the off-grid solar inverter, which is then cleanly used by consumers in their homes or any commercial place i.e. factory, shop, school, etc. Till this stage, operations of any solar system are identical. The main difference is beyond this point. After powering your home appliances, the extra energy generated follows one absolute route:

1. Dedicated Battery Storage: The excess energy is stored systematically in your deep-cycle batteries for use at a later part of the day or throughout the night when solar panels are resting.

Benefits of Off-Grid Solar Systems

01

Guaranteed 24*7 Power Supply

With an integrated option to utilize real-time solar energy during the day and deep-cycle battery power at night, the consumer will always have access to electricity and will never suffer from sudden power outages or blackouts.

02

More Savings

The main purpose of installing an off-grid solar system is to completely get rid of your external utility electricity bills and protect your household or business from unpredictable power cuts.

03

Good Investment Returns

An off-grid solar system offers a solid investment option. It features a fast 5.5-year payback time and provides free electricity for more than the next two decades. You can convert your property into a revenue-saving asset and achieve full ROI in just 5-6 years.

04

Works Efficiently

The off-grid system works independently with high-performance batteries. There is no operational limitation in the off-grid system unless you have miscalculated your initial structural solar load requirements.

05

Easy to Install

Installation of an off-grid system is straightforward and can be easily managed on the rooftop. It can be efficiently installed on residential rooftops, commercial spaces, government organizations, private institutions, etc., taking much less time for commissioning compared to complex grid-tied setups.

Primary Components

1. Solar Panel: The primary foundational component of the solar system. They comprise more than 30% of the total cost of the system, acting as the primary elements that capture solar energy and convert it cleanly into electrical energy.
2. Solar Inverter: This helps in converting the DC current produced from the solar panels into standard AC supply, making it fully usable for running your everyday household or commercial load safely.
3. Batteries: The critical backbone of an off-grid configuration. Placed right after solar panels, they comprise around 30% of the total system cost and act as the core containment component holding excess electricity for nighttime performance.
4. Panel Stand: This serves as the skeletal structure holding the panels securely in their optimal angle. Investing in high-quality aluminum or galvanized iron stands ensures your panels do not fall or suffer heavy damage during severe storms.
5. Solar Cable: The high-conductivity medium through which raw electricity transfers from your rooftop solar panels down to the inverter. These are separated cleanly into heavy-duty AC and DC wires.
6. DCDB / ACDB: The DC Distribution Board manages and connects the output power from the solar panels safely to the inverter input, while the AC Distribution Board accurately distributes power from the solar inverter out to your building's load.
7. Earthing Kit: Used to safeguard the entire independent solar layout from unpredictable surge or earthing currents. This kit is mandatory for total consumer and appliance safety.
8. Lightning Arrestor: Specifically engineered to protect your off-grid solar equipment from sudden, high-voltage lightning strikes during cloud thunder and heavy storms.
