In recent years, solar power systems have become quite popular as an alternative to traditional energy sources that are contributing to global environmental issues, especially global warming. Additionally, shifting to solar power has many long-term benefits, including a high Return on Investment (ROI), hassle-free maintenance, and added savings.
When it comes to India, grid-tie (also known as grid-connected) solar PV systems are being increasingly installed in residential areas; however, lately, there has also been a rise in off-grid solar system installations across the country. But if you’re not familiar with how off-grid PV systems function and whether you should invest in one, you’re at the right place – as we will discuss everything there is to know about off-grid solar systems.
What is an Off-Grid Solar System?
As the name suggests, an off-grid solar system is one that functions independently of the local electricity grid. This means that instead of depending on the grid for power backup, the PV system stores excess electricity in a solar battery – which can then be used at night and also during power outages. The solar power system comprises four main components, including the PV panels, an inverter, a solar battery, and a mounting structure to install the panels.
Now, let’s take a detailed look at the working of an off-grid solar PV system:
- First, the solar photovoltaic (PV) panels harness the sun’s energy and create an electric field, thereby producing Direct Current (DC).
- Second, the solar inverter converts the Direct Current (DC) into Alternating Current (AC), as daily-use electrical appliances like fans, lights, air conditioners, etcetera, cannot function on Direct Current (DC).
- Next, the generated electricity is supplied to your home through the solar inverter (by a connection with the main power supply).
- Lastly, all the excess energy that the solar panels produce is sent to the solar battery bank for later usage, especially during nighttime and also during power cuts.
So, installing an off-grid solar system will lead to energy independence in the long run as you will not be reliant on the local grid. Moreover, eventually, you will completely eliminate the costs of monthly electricity bills, resulting in significant savings.
The Benefits of Off-Grid Solar Systems
Now that you’re familiar with how an off-grid PV system works, let’s discuss a few of its benefits:
- Easy Access to Power Supply: One of the greatest advantages of an off-grid solar system is that you can easily access power supply even in remote locations. All you need to ensure is that the region receives ample sunlight throughout the day, making off-grid PV plants the ideal choice for areas with no access to the grid.
- Zero Dependence on the Grid: As we discussed, off-grid solar plants do not rely on the local grid for power production. In addition to resulting in energy independence, this also helps you avoid grid failure issues and unusual fluctuations, which can lead to high electricity bills.
- 24 x 7 Power Backup: Since an off-grid solar system stores excess energy generated by the panels into the solar battery bank, you will always have power backup. Whether there is an electricity cut in the area or it is simply nighttime, power backup will be the least of your worries.
So, that covers all the basics of an off-grid solar system. However, one additional thing you should know is that it is crucial to invest in a high-quality and high-performance off-grid solar PV plant so you can reap all the benefits.
