On-Grid Solar System Advantages

The most common type of rooftop solar system is an on-grid one, also known as a grid-tied one. These systems do not require batteries and are powered by the utility grid. It is best suited for customers who have stable grid power and few power outages. Apart from homes, educational institutions, industrial units, and commercial establishments rely on these systems as their primary energy source.

An on-grid system is intended first to enable the customer to consume solar energy. If the customer requires additional power, it is obtained from the grid. Excess solar units are exported to the grid if the customer's energy demand is less than the power generated by the solar system. This is made possible by a 'Net-meter.'

A net meter is a device that keeps track of the energy supplied to and drawn from the grid. The net energy consumed is recorded at the end of each month, and the consumer receives a bill. Because of this feature makes the on-grid solar system an excellent investment with high returns.

Benefits of on-grid solar

1. Significant savings on electricity bills

With a net meter, the consumer only pays for the excess electricity he consumes, resulting in a significantly lower monthly bill. Many of our customers have saved up to 90% on their monthly bills.

2. Easy maintenance

The lack of batteries in the on-grid system simplifies maintenance. It also removes the need for battery upkeep.

3. Synchronize with other sources of power

These systems can also be synchronized with an on-site diesel generator. This is crucial if grid power is unavailable.

4. Better ROI

Because there are no batteries in an on-grid solar system, the cost is lower than in other solar systems. In addition, it produces the most power compared to other solar systems. The low maintenance requirements and lower monthly power bills ensure the customer receives a 25- 30% ROI. This means that for every Rs. 100,000 invested in solar, the customer earns Rs. 25,000.

With these benefits, an on-grid system is best suited for a customer with stable grid power and minimal power outages. Other than homes, educational institutions, industrial units, and commercial establishments install on-grid systems because the system can synchronize with diesel generators to provide continuous power.

Differences between on-grid and off-grid solar systems:

The first and most obvious distinction between the two systems is that on-grid systems are connected to the grid, whereas off-grid systems are not. However, there are significant differences between them. Let's look at the main differences:

Electricity availability: An off-grid system does not rely on an outside source of electricity. It can only have power if the system generates it. This means that electricity will be available only when there is sunlight. To have constant access to electricity, an off-grid system must have a massive battery backup that can store electricity generated during the day and then supply it when it is not producing electricity. If there is a high electricity demand, a generator may be required to be connected to the off-grid system.

An on-grid system is connected to the utility grid, making it easier to access electricity. You can use electricity even if your solar system needs more electricity to meet your needs. Being connected to the grid allows you to have access to electricity at all times, whether you produce it or not. However, your on-grid system will also stop working if your utility power goes out.

Grid power outages:

Off-grid system: An off-grid system is not affected by a power outage on the grid. Because an off-grid system operates independently, a power outage will not disrupt access to electricity. Even if the power goes out, you will still have the ability.

On-grid system: this system is connected to the power grid and thus has access to electricity. However, you will be without power if there is a power outage. If the power at the grid fails, your on-grid system will also fail. In an on-grid system, this is the rule that must be followed. This prevents utility workers from becoming electrocuted while working on the grid.

Management of excess electricity production:

Off-grid system: depending on the system size, usage, and weather conditions, the system may produce more electricity than is required. Surplus electricity may be generated if your system is large enough and your usage is limited. Furthermore, an off-grid system is designed to generate excess electricity that can be used in the future. Batteries are connected to an off-grid system, allowing for excess electricity storage. This extra power can be used to power the house at night or when the weather is cloudy, and the system is not producing enough.

Conclusion:

There are advantages and disadvantages to both on-grid and off-grid systems, and neither is superior. It all depends on your energy consumption, location affordability, and feasibility. As a result, solar energy in Pakistan is regarded as an alternative energy source for economic prosperity. Solar energy is a plentiful resource in Pakistan that can be used to generate electricity.
