As the demand and prices of electricity have kept on rising, the world looks at renewable energy sources for its power needs. In recent years, solar energy has become a popular renewable energy source because of its falling costs and improving efficiencies.
A solar system is a setup that generates electricity by utilizing the solar energy system. A typical solar system consists of solar panels (which absorb sunlight), inverter (which converts DC into AC), mounting structure (that hold the panels in place), batteries (to store the extra power generated), grid box and balance of systems (wires, nuts etc.). A solar system comes in various sizes like 1 kWh, 2 kWh 3kW, 5kW, 7.5 kW, and 10kW.
What is Off-Grid Solar System (with Battery)?
A solar system which has battery storage and a backup is called an off grid solar system that generates electricity after power cut or during the night hours. It has the four major components, such as solar panels, inverter, battery and balancing of system. This solar system is more popular and comes with a power backup and it works independently of the grid.
How does an off grid solar system work?
An off-Grid solar system has four main components, a solar panel, solar inverter, battery, and balancing of the system. Solar panels generate DC Current in sunlight and store it in batteries. If you want to run DC applications (12V), such as Fans, Lights, you need a charge controller. Whereas, if you want to run AC appliances (220V), you need an inverter that converts DC Voltage to AC Voltage. Nowadays, all inverters work automatically, that is the electricity generated by the solar system charges batteries and runs appliances directly. Also, batteries run appliances directly in case of power failure.
It is the most common type of solar power system with backup. It works in day and night both, during the day, solar panel charges the battery and runs the home appliances such as Air Conditioners, Cooler, Television and submersible pump. At night, when the sun is not available, Inverter runs your home appliances using the battery power.
Advantage: No dependency on government electricity power
Drawback: Expensive than on-grid solar power system
What is the difference between on grid and off grid solar system?
The main differences between a grid-connected solar system (on-grid) and a stand alone solar system (off-grid) are:
An Off-Grid solar system will work even after a power cut, whereas an On-Grid won't work.
Off-Grid solar system is more expensive than a grid-connected solar system.
What is latest technology trends in solar inverters?
1. Full Form
Pulse With Modulation
Maximum Power Point Tracking
Up to 75%
Up to 95%
It charges Battery Only
It charges battery & runs home load during the day time
Double Price of PWM
For Single & Double Battery
More than 2 Batteries
There are two types of solar inverters, 1) PWM Based – relatively low efficiency, and 2) MPPT Based – high efficiency
PWM Based – It stands for a pulse with modulation, these inverter low on efficiency but prices are very low. For smaller needs, PWM based inverters are recommended for smaller use such as running 3-4 fans, 8-10 lights, 1-2 Television, 1 Refrigerator in day and night.
MPPT Based – It stands for Maximum power point tracking. If your purpose of investment in solar is to save electricity bill, then it is strongly recommended to opt for MPPT based inverters.
How much would an off grid solar system cost?
An off grid solar system comes in various capacities for different type of applications, such as, Small Home, 2-3 Floor Homes, Shops, Offices, School, Warehouses, and more. The minimum range of off grid solar system is 500W, average range is 1kW, and maximum range can vary from 3kW, 5kW, 7.5kW to 10kW. Simply, you can understand, the cost of 1kW off grid Solar System with Single Battery (12V) is approx. Rs. 80,000 and the cost of 1kW Off Grid Solar with Double Battery (24V) is approx. Rs. 1,00,000. The cost of any solar system depends on aspects like technology, brand, service and warranty.

How can I install off grid solar system capacity?
Rooftop Solar systems are generally installed on a home's roof, wall, tin shade, garden, door, etc. There are a few checks to be done before the installation of the solar panel stand, such as longitude and latitude angle, sun direction, wind pressure, wiring connection, area optimization, etc. To give the best installation according to customer needs, an engineer visit must be done.
Loom Solar is a trusted solar panel manufacturer in India when it comes to installation of a solar system. The company has successfully installed solar systems all across India in states like West Bengal, Uttar Pradesh, Haryana, Maharashtra, Tamil Nadu, Kerala, etc. Loom Solar has the experience of installing 1 kW, 5kW and 10 kW solar systems. Most of the installations have been done at residences, factories, transportation, hospitals, schools, offices, petrol pump, etc.
What appliances will be running on off-grid solar powered system?
In off-grid solar-powered system, how much power you can run depends upon the power of Inverter and it’s efficiency, generally all inverter comes with 80% efficiency, so, if you buy 3 kw Inverter system then up to 2,400 watts of peak power you can run at given point of time. An 1.5 ton inverter air-conditioner and 0.5 HP submersible can be run on 3kW Solar System successfully.
How much does it cost to install a solar energy system?
An initial cost of installing solar system is Rs. 25,000, if you have already single inverter battery and Rs. 50,000, if you have already double inverter battery. A 1 kWh solar system with Battery will cost you around INR 105,000 if you buy it from Loom Solar. It can easily power a 3-4 BHK home and run smoothly for 8-10 hours.
A 3 kW off-grid solar system will cost you INR 2,85,000 if you buy from Loom Solar. It is used to power larger homes, shops and offices and can run smoothly for 8-10 hours. It is a powerful solar system and can easily support the running of fans, lights, television, refrigerator etc. but not a 2 ton AC. Available at INR 4,85,000,
5 kW solar system is used for running even larger homes, offices and commercial shops. 10 kW off grid solar system can be easily used in offices, commercial shops and factories and comes with a price tag of INR 9,50,000. This system is capable of generating 50 units every day.
