On grid solar system

On-grid solar systems and DG sets are two popular options for providing power backup in commercial and industrial settings. While both options have their advantages and disadvantages, choosing between the two requires careful consideration of various factors. In this article, we’ll explore the differences between on-grid solar systems and DG sets and help you make an informed decision on which one is right for your needs.

Understanding On-Grid Solar Systems

An on-grid solar system, also known as a grid-tied solar system, is connected to the utility grid and uses solar panels to generate electricity. The system generates power during the day when the sun is shining and excess power is fed back into the grid. At night or when there is insufficient sunlight, power is drawn from the grid.

One of the biggest advantages of on-grid solar systems is that they are environmentally friendly, as they use renewable energy to generate power. They also help reduce electricity bills by offsetting the amount of power drawn from the grid. However, one of the downsides of on-grid solar systems is that they are dependent on the availability of sunlight, and do not provide power during power outages or blackouts.

Understanding DG Sets

A DG set, or a diesel generator set, is a type of backup power generator that uses diesel fuel to produce electricity. DG sets are commonly used in areas where the grid power supply is unreliable, or where there is no access to grid power. They are also used in industries where continuous power supply is critical, such as hospitals, data centers, and factories.

One of the advantages of DG sets is that they provide reliable power supply even during extended power outages or blackouts. They also have a relatively low initial cost compared to on-grid solar systems. However, DG sets are noisy and emit harmful pollutants, making them less environmentally friendly compared to on-grid solar systems.

Which is the Better Choice?

The choice between on-grid solar systems and DG sets ultimately depends on your specific needs and circumstances. Here are some factors to consider when making your decision:

  1. Availability of Grid Power: If your area has a reliable grid power supply, an on-grid solar system may be a good option as it can help offset electricity bills and provide power during the day. However, if grid power is unreliable or unavailable, a DG set may be necessary.
  2. Cost: On-grid solar systems have a higher initial cost compared to DG sets, but they have a lower operational cost in the long run. DG sets have a lower initial cost, but require ongoing fuel expenses.
  3. Environmental Impact: On-grid solar systems are environmentally friendly and emit no pollutants, while DG sets are noisy and emit harmful pollutants.
  4. Power Requirements: DG sets can provide higher power output compared to on-grid solar systems, making them more suitable for industries that require high power output.

Conclusion:

On-grid solar systems and DG sets both have their pros and cons. When choosing between the two, consider factors such as availability of grid power, cost, environmental impact, and power requirements to make the best decision for your needs.
