Many users have questions and common misconceptions about whether these systems can operate during a blackout; while they do need grid power to function, their ability to work in sync with the grid is what makes them a popular choice.

To fully appreciate the advantages of on-grid solar systems, it’s essential to have a basic understanding of how they function. The system works on a two-way connection, where it not only powers the home but also exports excess electricity to the grid. This process, known as net metering, oversees the accurate measurement of electricity transfer, ensuring fair compensation for the energy generated.

By quickly delving into the components, such as solar panels and inverters, one can better grasp the equipment and functionalities involved, helping to make informed decisions about adopting this grid-tie option that reduces reliance on conventional energy sources.

An on-grid solar system or grid-tie solar system works by connecting solar production to a grid station, making it impractical for remotely situated regions where no grid connection or national electricity is available. For such cases, off-grid solutions serve better. The on-grid solar system comprises the following components:

All these components are crucial to the functioning and efficiency of the system.

Solar panels are the primary component of a solar system and consist of photovoltaic cells that convert sunlight into electricity through the photovoltaic effect.

The inverter is an essential part of the system, responsible for converting the direct current (DC) electricity generated by the solar panels into alternating current (AC), making it compatible with the utility grid and household appliances.

The utility grid connection is crucial for on-grid systems as they are connected to the local utility grid, enabling seamless interaction and exchange of electricity between the solar system and the grid.

Grid interaction and backup are important as they allow the system to cooperate with solar power systems during periods of low solar generation, such as cloudy days or times when there is little to no sunlight available. 
In these instances, the on-grid solar system can interact with the grid and automatically switch to grid electricity, providing backup power when solar power generation is insufficient. This grid connection point ensures the system can communicate, import, and export power as needed, maintaining a steady and reliable power supply.

On-grid solar systems work by connecting directly to the grid station, which makes them different from off-grid and hybrid grid solar systems. This type of system can be understood through its functioning in several key components and is a popular option for homeowners and businesses in Pakistan due to its affordability and ease of installation. The grid-tied solar energy solution involves solar panels, grid-tie inverters, connecting wires, and a connection to the utility grid.

The on-grid solar power system arrangement begins with solar modules that absorb sunlight and convert it into electricity as Direct Current (DC). This current generated is then sent to a solar inverter that converts it into Alternating Current (AC), which powers electrical items in homes or businesses. The electricity generated is routed to the grid for day-to-day use, and a net meter records the energy provided and consumed by the household. At the end of each month, the outstanding balance is calculated and billed, making it easy for the greater public to manage their energy costs effectively.

The working principle of on-grid systems differs from off-grid setups. Solar panels collect energy from the sun, and the inverter keeps the system’s AC output in sync with the grid, allowing trouble-free connection and use. When the system produces more electricity than needed, the excess is divided and sent back to the nearest power grid through a bi-directional meter, ensuring that power is accurately measured and compensated. In remote or impractical areas without grid access, such systems would not function as intended, but in grid-connected locations, they provide a reliable and efficient way to save money and utilize clean energy.

Electricity generation is generated by solar panels, which are made of silicon wafers. When solar radiations fall on these silicon atoms, they excite loose electrons, transmitting energy and receiving more energy. This movement of electrons creates an electrical current, which flows through a network of connecting wires. 

The motion causes the generation of electrical current, and none of it goes to waste. This current is quickly grabbed and transferred to the inverter for further operations, ensuring minimal energy loss during transmission due to the use of highly conductible materials.

Energy conversion starts when electricity is produced by PV cells and then transmitted to the inverter via connecting wires. Initially in the form of Direct Current (DC), it must be converted to Alternating Current (AC) within a certain voltage range to be usable for electrical appliances on the premises. This crucial task is performed by on-grid solar inverters, which ensure minimum loss and highest efficiency. The inverter manages the input and output features, acting like the brain of the solar panel system, overseeing proper working and energy conversion to maintain the system’s functionality at 240 volts AC, suitable for home use.

Energy supply is crucial as the electricity transformed by the inverter to 240 V AC is then supplied to the house through conductive electricity wires with minimal to no loss. This electricity powers all appliances on the premises. The more appliances used, the more electricity is supplied, and less is stored. As electricity demand increases, production is supplemented by the current from the grid station, maintaining consistent energy supply for all needs.

Electricity storage refers to how excess electricity produced by the system is stored and utilized rather than going to waste. To counter this problem, on-grid systems use grid stations as virtual batteries, making them more affordable compared to battery-based solar systems. When electricity is being produced by an on-grid solar system but is not being used by appliances, the grid station receives this electricity, ensuring it is stored for future use.

The net metering process in Pakistan works differently from other countries to cater to the received electricity through a mechanism that measures the electricity units supplied to the grid station during off-peak periods, such as daytime. The system credits the owner by adjusting the bill amount based on the supplied units. The final amount is determined after deducting the price of the units supplied to the grid. Net metering allows users to benefit from their investment by selling excess electricity, making the system more rewarding.

The net metering system is a crucial aspect of on-grid systems that allows users to measure the difference between electricity consumed from the grid and electricity generated by solar panels.
