The term "off-grid" refers to an independent lifestyle, in which one lives without any public utilities like water, centricity, or air conditioning, etc. In the same vein, an off-grid solar system can serve as an alternative source of electricity to the government's grid.
This article considers some of the basic applications of off-grid solar systems. Also, we will explore the advantages of these systems over regular electricity and show you some of the best solar systems available.
What are the Applications of off-grid solar PV systems?
There are numerous real-life applications of off-grid solar PV systems. And we have selected some highlights of the most important off-grid solar PV systems applications.
1. Electrification in Rural areas
While constant electricity might seem normal to you, it is not an option for many people worldwide. According to statistics, over 2 billion people living in rural areas today do not have regular access to electricity.
As a result, most of these people depend on wood, and other fuel sources to generate their energy. Unfortunately, these methods of generating electricity can both be dangerous and expensive at the same time.
People in such environments face extreme socioeconomic disadvantages compared with those with access to electricity. That's because they are less likely to pursue higher education or even start businesses that can get them better living standards.
More so, without electricity, hospitals in rural areas cannot store medical supplies, putting people who rely on local health care at risk.
While this might sound hard to believe, it is the sad story of many people living in the rural communities of Africa, Latin America, and Asia. Leaving these people without electricity, a basic amenity in the 21st century, wastes high-potential human capital resources. If care is not taken, this could later become a source of diseases and imbalance to the nation’s development.
As a result, it is a major task for many national economies in Latin America, Africa, and Asia. Off-grid solar power systems solve that problem since it is simple to install. Furthermore, it provides rural and remote communities with independent, long-term, and sustainable electricity generation.
2. Emergency power supply during natural disasters and power outages
Natural disasters happen every once in a while, and they aren’t anyone's fault. Usually, floods, hurricanes, storms, etc., can lead to the power grids running out of power for days, weeks, or even months.
Wars and maintenance of power generation systems can also cause an unexpected interruption in the power supply. Sudden power outages can also happen due to power transmission malfunctions, storms, or brittle transmission lines.
Unfortunately, such sudden power outages are rarely effectively countered. When they happen, power outages can disrupt operations, such as the cooling of food, beverages, and medicines, or the operation of critical electrical appliances in hospitals, businesses, and public institutions.
However, Solar-powered Emergency Power Systems (SEP systems) can overcome such temporary power outages. These systems can provide power in disaster-affected areas or war zones with a high demand for immediate electricity supply.
Off-grid solar systems can serve as economical, stable, and long-term backup solutions to power outages. Users of these systems can even switch to the solar systems to avoid work interruptions, and keep their electricity-based systems operational.
3. Mobile Solar Systems for outdoor expeditions
You may require electricity at any time and in any place. However, for outdoor activities like camping and hiking, you cannot carry along the electricity you have at home. For such activities that use electricity-powered navigation, lighting, or communication systems, solar systems provide a reliable and mobile source of electricity.
Whether you are having your expedition on land or sea, mobile solar systems will allow you to power up all of your electrical appliances. Several market players provide a diverse range of mobile off-grid solar power system applications, including solar scooters, solar boats, solar bikes, solar bikes, and even solar drones.
4. Solar Water Pump Systems for provision of water
Water is a necessity for human and animal survival. It is also important for agriculture. However, there has to be electricity to get water flowing across a long distance. Solar energy can be an efficient and affordable energy source to power water pumps where water is needed.
Pros of the off-grid solar system
The following are some of the great advantages that these systems have over regular electricity.
1. Independence
These systems put you in control of your electricity generation and usage. You do not have to depend on the government’s electricity generation anymore. Whatever happens, you can always have the electricity you need whenever you want.
2. Safer environment
One of the biggest advantages of using solar energy is cleanliness. You use a renewable energy source that generates no carbon emissions whatsoever. And so, when you use an off-grid solar system, you are contributing your part to making the world better by reducing air pollution and carbon footprint.
3. Durability
Solar grid systems are built to withstand fierce and extreme weather conditions. So even if there is a fierce thunderstorm outside causing a power outage, your solar systems will still be there to provide you with the electricity you need.
4. Saving cost
At the initial stage, paying for a solar system can be expensive. However, in the long run, it is cost-effective as you will not need to pay for fuel anymore.
5. Ideal for rural areas
Off-grid solar provides a solution in rural areas where there is no viable connection to the government’s utility grid.
