In a time when renewable energy is getting a greater spotlight, solar power shines as a ray of hope. Among solar solutions, the grid-connected solar rooftop system rises as a champion, offering efficiency, sustainability, and economic advantages. This system integrates seamlessly with the local electrical grid, harnessing sunlight to generate electricity. 

Components like solar panels, inverters, and metering systems ensure optimal functionality, enabling users to reduce their carbon footprint and lower energy costs. With benefits ranging from cost savings to environmental impact, grid-connected solar rooftops illuminate a path towards a greener, more sustainable future.

Understanding On-Grid Solar System For Rooftop

An On-grid solar system for rooftops, also known as a grid-tied or on-grid system, is distinguished by its integration with the local electrical grid. Unlike standalone off-grid systems, grid-connected setups operate in tandem with the grid, enabling seamless energy exchange between solar panels and the utility grid.

Key Components:-

  • Solar Panels

Acting as the backbone of the system, solar panels absorb sunlight through photovoltaic cells, initiating the process of energy conversion. Through the photovoltaic effect, sunlight is transformed into direct current (DC) electricity, providing a clean and renewable energy source for the system.

  • Inverter

The inverter is a crucial component that transforms the generated DC electricity into alternating current (AC) electricity. This conversion is essential as AC electricity is compatible with most household appliances, ensuring seamless integration and utilisation of solar energy within the home.

  • Metering System

The bidirectional metre serves as the system’s eyes, meticulously tracking the flow of electricity between the grid and the solar setup. It accurately measures energy production and consumption, facilitating efficient management and enabling users to monitor their energy usage and savings effectively.

  • Mounting Structures

Mounting structures are vital for the physical integrity and optimal performance of solar panels. They provide sturdy support and proper alignment on rooftops. These structures ensure the panels are securely installed, maximising exposure to sunlight and enhancing overall energy production efficiency.

  • Grid Connection

Acting as the gateway to energy exchange, the grid connection enables the seamless transfer of electricity between the solar system and the utility grid. This connection facilitates the distribution of surplus energy to the grid during excess production and the retrieval of electricity from the grid when needed, ensuring a reliable and balanced energy supply.


  1. Solar Energy Harvesting-

Through the photovoltaic effect, solar panels capture sunlight and initiate the conversion process, generating direct current (DC) electricity. This sustainable method of energy harvesting utilises abundant sunlight to produce clean and renewable energy, providing a reliable power source for various applications.

  1. Inverter Conversion-

The inverter’s pivotal role is converting the generated DC electricity into alternating current (AC) electricity. This conversion process is essential to making electricity compatible with household appliances, ensuring seamless integration and utilisation of solar energy within the home or building.

  1. Grid Interaction-

During periods of surplus generation, excess electricity produced by the solar system is seamlessly fed back into the utility grid. Through net metering, users earn credits or compensation for the electricity they contribute to the grid, enhancing the economic benefits of solar energy adoption.

  1. Continuous Power Supply-

The grid serves as a reliable backup during low sunlight periods or times of high energy demand to ensure an uninterrupted power supply. By seamlessly drawing electricity from the grid when needed, users enjoy a continuous and reliable energy supply, enhancing the overall efficiency and reliability of the solar system.

Advantages of On-grid solar system for rooftop-

1. Cost Savings

By generating their electricity, users can significantly reduce their electricity bills.

2. Environmental Impact

Solar energy is clean and renewable. Its carbon impact is smaller.

3. Reliability

With access to the grid, users benefit from a reliable power supply, even during low sunlight periods.

4. Government Incentives

Various incentives, such as subsidies and tax benefits, further enhance the financial viability of grid-connected systems.

Types of On-grid solar system-

1. On-grid solar systems

These systems are integrated with the grid without battery backup and are cost-effective and widely trusted.

2. On-grid solar systems with Battery Backup

Also known as hybrid systems, these include battery storage for emergency power backup, albeit at a higher cost.

Incentivising Solar Adoption Through Subsidies-

Many governments worldwide recognise the importance of transitioning towards sustainable energy sources and incentivise the adoption of solar power through subsidies. One such initiative includes solar panel subsidies aimed at making solar energy more accessible and affordable for homeowners and businesses. Additionally, on-grid solar subsidies further encourage the installation of grid-connected solar systems by providing financial support or tax incentives, thereby promoting the integration of clean energy into the existing electrical grid infrastructure. These subsidies play a crucial role in driving the widespread adoption of solar energy, contributing to both environmental sustainability and economic prosperity.


On-grid solar systems for rooftops represent a leap towards sustainable energy practices, offering a myriad of benefits to homeowners, businesses, and the environment alike. While they come with certain limitations, their advantages far outweigh the drawbacks. As we navigate towards a greener future, let us harness the power of solar energy and illuminate our path towards sustainability.
