20kW Solar System Price in India with Subsidy (2024)

20kW Solar System Price in India with Subsidy

The amount of sunlight that touches the globe’s surface during the day is adequate to meet all of the world’s energy needs for an entire year. Solar photovoltaic (PV) is a powerful technology that turns sunlight into electrical energy. This power can be used to run our homes and commercial spaces. 

Depending on how much power you need annually, you can choose different capacities of solar systems, from 1kw to 20kW solar systems or even higher. A 20kW residential solar system can generate enough electricity to power your business or a large residential property.

The Working of a 20kW Solar System and Its Benefits

A metal panel frame with glass is typically used to house silicon-based solar panels. Photons, or light particles, hit the top layer of silicon solar cells in a solar panel, which displaces the electrons from the atoms of silicon. The flow of electrons results in the generation of energy in DC form.

Having been carefully positioned under the sun in a shade-free area, solar panels start to generate current and voltage. Our solar panels must be connected to an inverter, which converts DC into AC for our homes because most appliances and equipment run on alternative current (AC).

The Benefits of A 20kW Residential Solar System

Reduced Electricity Bills

You can observe a significant decrease in electricity bills that eventually eclipse your upfront 20kW solar system cost. The lower monthly cost of electricity is the biggest benefit of using solar energy at home. Also, you reduce your reliance on grid-based electricity by switching to solar energy. Your annual utility savings rise significantly as solar energy offsets your grid power usage. 

Lower Dependence on Centralized Grids

Your dependence on centralized private or public grids consequently falls when you switch to a 20kW solar system. When demand is rising, and supply is erratic, independence is the most secure and long-lasting option. Your solar power system will be more self-sufficient once a battery backup is added. In this scenario, you would be producing energy and storing it to prevent outages when the grid goes down. 

Good for the Environment

Conventional sources of electricity are detrimental to the environment that emit harmful gases into the atmosphere. Generating energy using a 20kW solar system is a clean, emission-free process. The effects of climate change can reverse as more and more grid consumers switch to solar and become self-reliant.

Types of a 20kW Solar System

Many businesses have acted to innovate solar systems by considering the range of solar systems. Due to this invention, we now have various solar system choices on the market. Three different types of 20kW solar systems are being offered by solar energy companies.

  • On-Grid Solar System
  • Off-Grid Solar System
  • Hybrid Solar System

20kW On-Grid Solar System Specification

The on-grid framework is your best option if you are on a budget, and your land receives enough sunlight throughout the year. 20kW on-grid solar systems convey the converted current to power household appliances while transferring the unused solar energy to the public grid. All on-grid solar panel systems are regulated under the net metering mechanism. A net meter is paired with solar panels to keep track of the energy transfers between your home and the grid. 

The surplus solar electricity that you don’t use at your home or office is fed to the grid. Your electricity bill shows a positive balance of solar credits for every unit sent by your solar panels. Also, you have the flexibility to withdraw power from the local grid when solar production declines due to inclement weather.

20kW Off-Grid Solar System Specification

A 20kW off-grid solar system is a cost-effective way to produce electricity on-site and power your property in a remote location. Solar batteries serve as an alternative source of power instead of the grid. The battery bank stores all the surplus energy units to power your home during night hours and inclement weather. 

Going off the grid means you entirely depend on your solar panels + battery system. You don’t have to worry about power outages if the grid is down. Also, you can avoid monthly bills because an off-grid solar system doesn’t use the net metering strategy. 

20kW Hybrid Solar System Specification

The price of a 20kW solar panel system in India is the highest if you choose a hybrid framework for your property, but for good reasons. A hybrid solar energy plant can help you unlock the maximum solar potential for your location and becomes a profitable investment in a matter of a few years. It combines the best of solar systems operating on and off the grid.

20kW hybrid solar systems help you earn solar credits under net metering regulations. At the same time, it uses a strong battery bank to prevent power outages and ensure 24 hours of power supply without any worries about high electricity costs. 

Therefore, each type of 20kW solar system has its own set of advantages and disadvantages. Before selecting the ideal solar system, consider your budget and energy needs. The price of a 20kW on-grid solar system is less and provides a reliable electricity supply except when the grid is down. This is the reason they are most preferred by people.

20kW Solar System Facts 

  • A 20kW Solar System works well for small and medium-sized businesses. On average, a grid system may produce 2,400 units per month or 80 units per day throughout the year. Installation calls for a 100-square-meter area free of shade. 
  • Within 6-8 years, you are likely to recover your initial solar system cost and further receive significant ROI (return on investment) throughout the system’s lifespan of 25+ years.
  • Typically, a 20kW solar system comprises 55 to 60 solar panels.
  • The cost of 20kW solar systems has dropped significantly in recent years. Thanks to advancements in solar PV technology and improved financing options, the price of 20kW solar panels in India is likely to fall within your budget.

20kW System Installation Cost in India

Generally, a fully installed 20 kilowatt solar panel system price is between Rs. 9 lakhs and Rs. 16 lakhs. This system can cut your annual power costs by up to 70%-90% depending on the cost of electricity in your region and your power usage. Depending on your location, a top-of-the-line system that uses high-efficiency solar components and innovative mounting modules is likely to be on the higher side.
