Gel Batteries for Solar

When it comes to solar batteries, there is an ongoing debate between gel batteries and AGM batteries. Since no two solar installations are the same, many factors, like the climate and discharge rates, impact your choice of solar batteries.

For instance, if you are designing off-grid solar systems, you may be required to select suitable batteries for your solar panel system carefully.

To help you with this, we will help you identify the differences between a gel battery and an AGM battery in this article. So, let’s get started!

Key Takeaways

• Gel and AGM batteries are lead-acid batteries used in solar installations, each with advantages. Gel batteries have silica in the electrolyte mixture, providing extra power and long-term energy storage benefits. AGM batteries are sealed, maintenance-free, and perform better with minimal gassing and acid leakage.
• The choice between gel and AGM batteries depends on your specific solar system needs. Off-grid systems, which operate independently from the grid, often use deep cycle batteries like gel or AGM batteries to store energy generated during the day for nighttime use. Grid-tied systems, on the other hand, use battery backups only during power outages.
• Careful selection of the appropriate battery type, such as gel batteries, is crucial for the success and longevity of your solar energy system, as mistakes can lead to damage. Regular maintenance and monitoring ensure a longer lifespan for your solar system.

What Are Gel Batteries?

Gel batteries are lead-acid batteries with silica inside the electrolyte mixture, which helps create a gel-like substance. In such batteries, the electrolytes stand solid between the positive and negative plates.

So, if you have a lead-acid battery housing, then gel batteries are beneficial in providing extra power to your overall battery system. They also come with many other benefits for long-term energy storage.

What Are AGM Batteries?

Absorbed glass mat (AGM) batteries are a type of sealed lead-acid batteries that are used for solar storage options. These batteries are resistant to vibration, are sealed, and maintenance-free.

Compared to traditional valve-regulated lead-acid VRLA batteries, they offer better performance, minimal gassing, and less acid leakage. Additionally, they are compatible with solar electric vehicles and are excellent energy storage options for anyone looking for sustainable alternatives.

Thus, AGM and gel batteries are lead-acid batteries and are different from lithium-ion batteries. However, lead-acid batteries are more commonly preferred as a backup energy source for solar panels as they increase the battery life of the solar storage.

Types of Battery Systems

There are two main types of battery systems- grid-tie with battery backup and off-grid systems.

Off-Grid Systems

An Off-grid system is a type of battery system independent of grids. During days when the sunlight isn’t sufficient, for example, on cloudy days or at night, the solar power system of the house depends on the batteries.

In these systems, the highest amount of electricity is generated during the peak hours of the daytime when the solar light is maximum, while the highest consumption of this generated electricity occurs at night.

For the electricity to last all night or even longer on days when the sunlight is insufficient, the battery bank must be fully charged during the peak hours of solar light. As such, the batteries designed for such type of functioning are deep cycle batteries. This means they charge throughout the day and deep discharge at night.

Under this category, the most common types of batteries produced are flooded batteries, AGM, and gel lead-acid batteries.

Grid-Tied System

The grid-tied system works with the help of a battery backup only during a power outage. Under the regular functioning of this system, the DC power from the solar panels passes through a grid-tier inverter that converts it to AC.

With the help of this power, the panels can run appliances in your home. Simultaneously, some amount of this electricity can also charge the battery bank. So, during a power outage, when the inverter disconnects itself from the grid, your home’s electricity supply will run as an off-grid system.

How to Choose Your Solar Batteries?

Lead-acid (gel-based or AGM) batteries are the most commonly preferred battery type, especially if you decide to go for an off-grid system. But when it comes to choosing between the two, it is important to remember that each type has advantages and disadvantages.

For instance, gel batteries are specialized in deep-cycle batteries. They are sturdy and low-maintenance, and the electrolyte inside the battery prevents the cell from leaking in case of any damage. However, they are also slightly expensive and discharge faster than flooded batteries.
