Everyone who cares about the state of affairs and the environment is looking for ways to save on energy consumption and prevent further damage to the environment. From homeowners to manufacturers, the list is endless. There is a spike in the cost of energy, whether you use electricity or gas, making it more vital to find alternatives to them.
One of the best alternatives is solar energy, specifically off-grid photovoltaic systems, and they are becoming more popular. Before now, remote areas, islands in the sea, and farms used them to generate electric power for basic needs. These users need them because of the distance from major power sources.
However, the story has changed. While the cost of getting and installing them seemed too high at the beginning, manufacturers now make and sell them at reduced prices. Therefore, installing and using an off-grid solar power system is attainable, with the promise of a constant supply of electricity from a clean and free source. Read this article to learn more about how solar power works.
The Role of a Battery in an Off-Grid Solar Power System
An off-grid system is one that has no connection to an area’s electric power grid. This is the direct opposite of an on-grid type, where there is a direct connection to the power grid. An off-grid solar system usually relies solely on solar energy and the produced energy is stored in batteries and used where the system is installed.
In other words, these systems will not beneficial if there is no way of providing and storing electricity for a few days. This is where the batteries come into play. Off-grid solar power systems use inverters and battery banks to save energy for use, sometimes for up to five days, depending on the size of the batteries or inverters and usage.
Many homes use this system for power supply and have completely cut electricity bills or lowered the cost a significant amount. There are many companies that install off-grid systems with all components, and they also provide resources to educate on the benefits of using the system. Consider the Sacramento battery system for solar if you live in the Sacramento area and want to try an alternative source of power.
Components of an Off-Grid Solar System
To understand how an off-grid solar works, you must know all the components and how they operate. Apart from the batteries, there are other key components, basically four of them.
The most conspicuous part of the system is the solar panels. They are the part that draws energy directly from the sun. They convert the energy particles in sunlight, which are called photons, into electric power to supply voltage to a house. Without the panels, the solar power system does not work.
A panel consists of cells, called solar cells, and they are tiny squares that make up each panel. Efficient and cost-effective panels are those with cells in the range of sixty and one hundred and forty-four. Any panel outside this range may not deliver desired results.
Usually, the power stored in the battery from the solar panels is Direct Current (DC). But what a house needs to power appliances is Alternating Current (AC). This is where an inverter comes in; it draws the power from the battery bank and converts it to AC before transmitting it to loads in a house. Then, you can use it for any purpose.
Typically, there are different sizes of inverters, and the one you use will depend on the required off-grid loads. Also, the size will determine whether it will accommodate large loads or small loads. In other words, the size of the inverter must correspond with the loads that simultaneously run in the system. In addition, the voltage size of an inverter must agree with the battery bank. You cannot use a 24-volt inverter with a 12-volt battery bank; it must be a 24-volt battery bank.
● Charge Controller
The charge controller manages the energy flow from the panels to the batteries. It also ensures the batteries do not overcharge to preserve their life. What it does is to reduce the charging current slowly as the batteries become almost full, leaving only that which is enough to fully charge them and keep them from running low.
The battery in a solar power system is, perhaps, one of the most critical parts and also expensive. But it is what keeps the system running for long hours, even when there is no sunlight or other alternatives with which to charge the system.

There are two types of battery chemistry for an off-grid solar system. One is lithium and the other is lead acid. Lead-acid has two options: sealed Absorbed Glass Mat (AGM) and flooded batteries. AGM batteries are sealed and need no maintenance, which means they are expensive. But flooded batteries need maintenance to prolong their lifespan. However, that makes them less expensive than the AGM ones.
Lithium batteries are different in a good way. They do need maintenance and are smaller in size than lead-acid batteries. Also, they charge faster and do not need to be charged fully before they work. What’s more, they take up less space than their counterparts.
Living off the grid may not be for everyone, but if you do, a solar power system is one cost-effective way to stay connected to electricity. When purchasing the system, you will need to consider the type of battery to buy, not only because of cost but also because of service and maintenance. Manufacturers of lithium batteries offer a significantly higher number of warranty years on them, so you may want to consider that option.
