How Much Does It Cost To Install A 3kW Solar System?

A 3kW solar system consists of solar panels that can generate up to 3000W/h electricity. These systems are commonly installed on residential rooftops or small commercial buildings. A 3kW system might include around 8-12 solar panels, depending on their wattage and efficiency. This size of the system can cover a significant portion of a household's electricity needs, reducing reliance on the grid and lowering energy bills. However, the actual output of the system can vary depending on factors such as location, orientation, shading, and weather conditions. 3kW solar system is the best fit for those who are looking for a complete solar solution for home including solar battery and solar inverter. Let’s understand more about the 3kW solar system. 


What Is The Process Of Solar I­nstallation?

These are the steps that you must follow to install a solar panel.

  1. Site survey: When setting up solar panels, an engineer will visit your place first. They will come over, check the installation area, space, etc, and give you all the details. This may include how much it might cost and which solar solution would be the best for you.
  2. Assemble solar panels: First, put up the balancing structure for the solar panel. Use nuts and bolts to make it secure. Make sure to tighten the nuts and bolts properly.
  3. Solar wiring: It includes components like earthing, lightning arrestors, solar panels, DCDBs (DC Distribution Boards), solar inverters, batteries, ACDBs (AC distribution boards), distribution boxes, electric meters, and grid connections.
  4. Connect solar panel and solar inverter: After the setup is finished, connect the wires. First, connect the wire from the positive terminal of the solar panel to the wire from the positive terminal of the inverter. Then, connect the wire from the negative terminal of the solar panel to the wire from the negative terminal of the inverter.
  5. Connect the solar inverter and battery: Connecting a battery is important for an off-grid solar system. It helps you save up electricity for when you need it later. To get everything working, you need to connect the inverter and batteries. Connect the wire from the positive terminal of the inverter to the positive terminal of the battery.

How Much Does Cost A 3KW Of Solar System?

The cost of a 3kW solar system for homes for electricity supply ranges approximately from Rs. 1,80,000 to Rs. 2,25,000. This includes everything you need the solar panels, delivery, and installation. 

How Many Solar Panels Are Required For 3KW?

Usually, when the sun shines bright, a regular solar panel can make around 250-300 watts of power. If you want a 3kW system, you will need about 10 to 12 solar panels.

How Many Watts Is One Solar Panel?

Most solar panels make approximately 250 to 400 watts of power and produce roughly 1.5 kilowatt-hours of energy every day.

How Many Units Can A 3kW Generate?

This system can make 15 units every day and can run your stuff like fans, lights, TV, fridge, etc., using solar power instead of electricity from the grid.

Which Appliances Run On A 3kW Solar System?

Appliances that can be run on a 3kW solar system are a Water Motor, Washing Machine, Induction Machine, Mixer & Juicer, Iron Press, Refrigerator, TV, Ceiling Fans, Lights, Laptop, and 5HP Submersible Water Pump.

What Are The Benefits Of On-Grid Solar System?

The benefits of on-grid solar system are

  1. Cost Savings: On-grid solar system can cut down on your electricity bills. When these systems make more electricity more than you need, you can sell it back to the power grid. This can earn you credits or money through net metering programs, helping you save even more.
  2. In-Built Savings: Each month, your energy bills will go down. These savings will add up over time. Whether you pay in cash or take a loan, you will also notice the savings or see them grow into something significant over time. Everyone will experience different amounts of savings because of the different locations, how much sunlight they get, and other things that affect solar power. Some might save 30%, while others could save all of their energy costs.
  1. Financial Incentives: The government and utility companies give incentives to encourage people to install solar panels that connect to the power grid. These incentives could be tax breaks, refunds, or special rates for selling excess energy back to the grid. They are meant to make it easier for people to afford to install solar panels and make their money back quicker.
  2. Long-term Savings: When you buy a solar system, you'll save money every month. Instead of paying the utility company for electricity, you use energy from solar panels. Any extra energy you produce gets credited to your account. This gets sorted out properly through a system of importing, exporting, and banking.
  3. Low Maintenance: On-grid solar systems are easier to take care of than off-grid. This is because they do not need batteries to store energy. Usually, checking the solar panels regularly and cleaning them once in a while keeps them working properly.
  4. Grid Stability and Reliability: On-grid solar systems spread out power production over a larger area, which makes the electricity grid more stable and dependable. When lots of people need electricity, especially during busy times, solar energy can pitch in to ease the pressure on the grid by supplying extra power. 

Is A Loan Facility Available For On-Grid 3KW Solar System?

Nowadays, it's easy to get things like phones, cars, or houses because of loans and payment plans. You might know how to get a phone or a car with monthly payments, but do you know how to do the same for a solar system?

Yes, you can buy a 3kW solar system on EMI/Loan. In India, there are about 80 crore people who use bank cards. However, only about 50 lakh people, roughly 1%of people use credit cards that let them pay for solar systems in installments.

Is There A Government Subsidy Available For A 3KW Solar System?

In India, the government offers the facility of subsidy or other financial rewards to support the use of solar power for solar system. The subsidy is only available for residential consumers. Subsidy for residential households are Rs. 30,000/- per kW up to 2 kW is Rs. 18,000/- per kW for additional capacity up to 3 kW. Total Subsidy for systems larger than 3 kW is Rs 78,000.
