Do all Off-Grid Solar Systems Need Batteries?

If you are interested in investing in a solar power system for your residential or commercial property you probably know that there are two broad categories that you can choose to go with; these being grid connected or off-grid systems. One of the best solar mainly used in the UK is the off-grid solar system. People ask, “Do all off-grid solar systems need batteries?”. The answer is that Yes because you need to store the energy.

There are different types of solar batteries on the market, they all come with their advantages and disadvantages. When buying an off-grid solar system you need to consult the technician to help you choose the best batteries. If you have a poor battery, it means you won’t fully enjoy the benefits of the solar system. The most off-grid solar panel does not work at night or they produce less energy and thus you need a battery to light up. Types of batteries include;

Flooded batteries: this type of solar battery looks the same as car battery the only difference is the lead plate thickness. This helps them to have a longer life.

Gel batteries: in this type of solar battery, the acid is immobilized using silica gel. This ensures that the electrolyte not to produce off-gases and makes it safe to use

AGM batteries: AGM is Absorbed Glass Mat. The matting is fixed in between lead plates. Like in a gel battery, matting immobilises the electrolyte.

Off-grid power systems appeal to others who want to gain complete independence from the main power grid. This can be the preferred option for various reasons, such as the remoteness of the location. Many individuals or households who choose to go with an off-grid solar power solution find that it makes financial sense to do so because of the high cost of grid connection in extremely remote locations.

Others choose off-grid solar because they feel the urge to be completely independent of the main power grid and drastically reduce their carbon footprint and culpability for global warming and climate change. Off-grid solar power systems can initially involve higher start-up costs due to more panels being necessary as well as several high-capacity, deep-cycle batteries which are used to store excess power during high yield periods during the day for use when solar energy is not available later in the night. There are certainly some downfalls involved with off-grid solar; these involve the complete dependence that is placed on the system. With a grid-connected system, if you use more power than your system has generated through the day you simply begin to tap into the grid’s power supply, whereas with an off-grid system if you happen to use more power than your system can generate you don’t have any options left.

This means that more forethought is necessary before investing in an off-grid system, you should consult with an electrician to find a system which best suits your needs, and during times of low power yields or cloudy weather increased energy efficiency measures and rationing of power may be necessary. Nevertheless, a well-planned off-grid solar power system is an excellent investment for many rural or remote residential and commercial properties, the savings can be enormous not to mention the benefits to the environment. So, start doing some research and see if an off-grid solar power system could be right for you.
