Introduction to On-Grid Solar Systems

The quest for ensuring we find efficient and renewable sources of energy has led solar energy to become one of the leading sources of electricity. Different kinds of systems in terms of solar energy include the on-grid solar systems which are renowned to be best due to aspects of efficiency, cheap to install and can easily incorporate with other energy systems. This article focuses on on-grid solar systems and discusses the details on the part and functions of on-grid systems, the benefit of on-grid system compared to off-grid systems, how on-grid solar systems are installed and the importance of on-grid systems for moving towards renewable energy.

Understanding On-Grid Solar Systems

On-grid solar systems, which are also referred to as grid-tied or grid-interconnected solar systems, are meant to be in parallel with utility companies. This differs from off-grid solar system that solely depends on solar energy and batteries while the on-grid systems harmonize the solar energy with the utility power grid. This arrangement ensures that if there is shortage of power produced by the solar power, the consumers can directly draw power from the grid. Also, excess energy, which may be generated by the rooftop solar panels during the day, can be fed back to the network thereby providing an opportunity for making savings. Those who wish to find a compromise between the two can implement the advantages of both on-grid and off-grid solar power systems by using a hybrid solar system to guarantee uninterrupted power supply.

Main Parts of On-Grid Solar System

• Solar Panels: These are found at the center of each solar system to absorb the sunlight it will convert the light energy exercising DC electricity. These are of different types such as the monocrystalline, polycrystalline and the thin film types of silicon cells; their efficiency and cost depends on the type.
  
• Inverter: This vital stage transforms the DC Electricity from the solar panels into AC form, which can be used in the homes and synchronized with that from the power grid.
  
• Grid Connection: There is also a bidirectional meter for electricity connection to the local utility grid and also to the system. This meter is used especially in net metering, where system owners can be rewarded for the power they put back into the electrical grid.
  
• Mounting System: The panels are mainly installed on roofs of buildings or on the ground structures set with different types of mounting systems to ensure the maximum direct exposure to the sunlight.
  
• Monitoring System: Some of these on-grid systems come with monitoring features that enable the users to check the efficiency of the solar energy and management features of the system.

The following are the benefits of on-grid solar systems:

FAQ

What are on-grid solar systems?

On-grid solar systems are the solar power systems that are interconnected with the public electricity network, or the utility grid. Such systems harness power from the sun through the use of solar panels and feed the power both to the national grid and to the user’s home or place of business. If the output of the solar panels is higher than the load demand, then the energy is fed back to the utility grid, the user is then allowed to draw from the grid at these credit hours. On the other hand, when the solar panels generate less electricity than required by the house, then the system pulls electricity from the grid.

What is the price of a 30 kW on-grid solar system in India?

The prices for the on-grid solar system of thirty kW could range depending on the quality of the solar panels, the inverters, the installation charges and any extra features like a monitoring system in India. The cost of on-grid solar system in India as of 2024 exists between ₹40,000 to ₹50,000 per kilowatt.

Estimated Cost Breakdown
Low-End Estimate: ₹40,000 per kW for 30 kW = ₹ 12,00,000
High-End Estimate: ₹10,000 per kW cogeneration × 30 kW = ₹ 30,00,000

Thus the cost of a 30 kW on-grid solar system in India varies from ₹12,00,000/- to ₹15,00,000/- only. This estimate can also differ depending on the components enlisted for usage and the kind of installation to be made. Moreover, the incentives or subsidies provided by the Indian government for the ecosystem players can make the Net Cost even lower.
