Best 3kW Solar System In India | Complete Guide For Beginners

The 3kW solar system can be placed on the rooftop of the building with the help of solar mounting systems. This installation of the solar systems helps in running other devices like laptops, refrigerators, solar lighting, solar AC, Solar water pumps, etc. If you are thinking that how much power does a 3kw solar system produce then let me tell you that it can be generated about 12 – 15 units of energy per day and this lasts for 5 to 10 hours.

The 3Kw solar system is an ideal solution for people who want to go green but don’t have enough land or money to put up a large-scale solar farm. 3Kw solar systems can power your home, but they are also powerful enough to power an office building. These solar systems are a big deal.

The technology behind them is now widely used in many countries around the world. This technology has increased the capacity of solar energy, especially in areas where people cannot rely on conventional power supply or infrastructure. These 3Kw solar systems have been installed all over the world, allowing everyone to produce their electricity and use renewable energy. These systems are also cost-effective for some people.

In a short period, these 3Kw solar power stations have proved their worth as an alternative energy source to conventional electricity and fossil fuels like coal and oil. Experts from around the world advocate this technology because it is environment friendly; produces no carbon emissions, reduces dependency on existing infrastructure (i.e., grid).

They believe that there will be fewer problems with water pollution and less petroleum used to transport coal. Also, because of the storage systems, your 3Kw solar system will not be depleted by a large storm or shortened power outages from frequent storms. These systems will create no to minimal amounts of dust in the atmosphere. These 3Kw solar home power stations are easy on the environment and can be used for four decades without any upkeep or maintenance required.

If you are looking to go solar, then here’s are an article about 3Kw solar systems where you can find its types, pricing, benefit, and many more. So let’s have a look at them.

What Is A 3kW Solar System?

Definition 3kW Solar System
Definition 3kW Solar System

3Kw solar system is a type of photovoltaic (PV) power system that can generate 3 kilowatts of electricity. It is composed of multiple PV panels connected in series and arranged in a way to maximize the output from the sun. These systems are also called multi-tiered or polycrystalline solar panel arrays because they contain multiple crystalline silicon PV cells, often at different heights on the same panel. This system includes:

  1. Solar panels- These are mounted on a roof or placed in an area with direct sunlight. They absorb light and convert it into electricity by using photovoltaic cells.
  2. Inverter- This device converts DC power from the solar panels into AC power which can be used to run appliances, electronic devices, and lights within your home or business premises.
  3. Cables- There are two types of cables required for this setup: interconnecting cables that connect the inverter to the solar panels and wiring for connecting the inverter to other devices such as appliances, lights, etc.

3Kw solar systems are cost-effective and efficient. It is the most common size in residential and commercial solar installations. They can be a perfect fit for houses with a low roof pitch, small gardens, and minimal sun exposure.

Benefits Of 3Kw Solar System

The 3kW solar system can be placed on the rooftop of the building with the help of solar mounting systems. This installation of the solar systems helps in running other devices like laptops, refrigerators, solar lighting, solar AC, Solar water pumps, etc. If you are thinking that how much power does a 3kw solar system with batteries produces then let me tell you that it can be generated about 12 – 15 units of energy per day and this lasts for 5 to 10 hours.

Types Of 3Kw Solar System

There are three types of solar systems are present. But you can say that the types of solar systems are run on the same Solar PV and their components and the exceptional features distinguish them. Let’s discuss them in detail.

3kW On-Grid Solar System

3kW On-Grid Solar System
3kW On-Grid Solar System

 This type of solar system runs with the electrical grid. This solar system consists of solar panels, solar inverters, and other solar accessories. ON grid solar system has special features of solar net metering which help to balance the extra electricity and this extra electricity can be sent to the government. 

Benefits of installing a 3kW On-Grid Solar System include:

  1. You will not have to worry about high electricity bills because it is solar-powered. 
  2. It saves time because you don’t have to pay electric bills every month as they are generated by the solar panels themselves. 
  3. It provides energy independence which means that you don’t have to rely on other sources of energy such as the grid.

3kW Off-Grid Solar System

The off-grid solar systems do not need any kind of electricity grid to work. The solar panels of this solar system are run by the solar battery which helps in giving the power to collect the energy and then transfer it to the other solar products. This is very cost-effective. 

A benefit of an off-grid solar system is that it can provide electricity for the home, business, or other buildings without using the grid which often charges higher rates and has less reliability. 

Another benefit of an off-grid solar system is that it doesn’t require batteries and can run on sunlight alone without interruption from the grid.

3kW Hybrid Solar System

A 3kW Hybrid solar system is a combination of both solar panels and batteries that can be used to provide electricity during the day and store power for use at night.

There are many benefits of this system such as:

  1. It can produce more energy than traditional systems.
  2. It can reduce your dependence on fossil fuels by using renewable sources like solar power, wind power, and hydroelectricity.
  3. It reduces your carbon footprint by reducing your consumption of electricity from coal-fired plants.
  4. It increases your independence from utility companies by being able to produce enough energy for personal use or to sell back to the grid when needed.

3kW Solar System Price In India With Subsidy

The price of a 2kW solar panel is approximate, depending on the size of your system and type. The average payback period for this kind of system would be up to 10 years. In India, the average payback period for this kind of system can be as low as 2 years.

The price of the solar systems is calculated per watt. The average price of the 3kW solar systems lies from Rs. 47.95 to 76.98 per watt. Now let’s have look at the price, shall we?

Solar SystemSelling PricePrice/Watt
3kW Conversion KitRs.1,00,000Rs.33.33
On-Grid SystemRs.1,43,878Rs.47.95
Off-Grid SystemRs.2,07,609Rs.69.20
Hybrid SystemRs.2,30,967Rs.76.98

The subsidy on the solar systems is acting a very vital role to influence people to install the solar systems in their homes. This is a tax credit or cash rebate for people who buy solar panels, install them on their property, and sell the electricity they generate back to the grid. The government of MNRE also offers a 30% Investment Tax Credit (ITC) for commercial projects that invest in renewable energy technologies like solar photovoltaic systems.

3kW Solar System Power Backup 

A 3kW solar system power backup is a solar power system that is capable of storing enough energy to supply electricity for your home or business. A 3kW solar system with battery backup will provide enough power for an average household for about 10 hours during a power outage.
