When Should You Repair or Replace a Solar Battery?

The solar energy landscape is on the rise globally. Without a doubt, solar battery systems are a crucial part of any residential or commercial building. The solar batteries store energy for use during peak hours or when sunlight is limited.

However, like all components, solar batteries also tend to wear out over time. That is when this question pops up into the mind: When Should You Repair or Replace a Solar Battery? Knowing when to repair or replace them can save money, maintain energy efficiency, and protect your entire system.

In this blog, we explore the signs that indicate your solar battery needs attention, when to repair or replace the solar battery and some maintenance tips to extend the battery life.

Understanding the Lifespan of a Solar Battery

Before we move into the nitty-gritty of when to opt for a repair or replacement of the solar battery, it’s important to know more about its life span. 

The average solar battery lasts anywhere from 5 to 15 years. However, that depends on its type, usage patterns, and how well it's maintained. Lithium-ion batteries, which are most commonly used in solar applications, tend to have longer lifespans and higher efficiency rates compared to lead-acid batteries.

There are several factors that determine the life span of the solar battery. For example, if you use the solar system often, the battery won’t last long. Lithium-ion batteries, while relatively more expensive, tend to last longer. If the storage area of the battery is temperature-controlled, the life span increases.

Signs Your Solar Battery May Need Attention

Your solar battery will not suddenly die one day, leaving you in complete despair. There are several signs that the solar battery gives. You only need to pay attention to these symptoms to take quick action. 

These are - 

• Declining Storage Capacity: If your battery no longer stores as much energy as it used to, this could be a sign that the battery is deteriorating.

• Inconsistent Power Supply: Power flickers, outages, or reduced backup time may indicate battery trouble.

• Unusual Noises or Odours: A hissing sound or strange smell could be a sign of internal damage or leaks within the battery.

• Visible Damage or Leakage: Cracks, corrosion, or bulging should be treated as immediate red flags, followed by urgent action.

When Should You Opt for a Repair?

Now the question arises, when should you opt for a repair and not a replacement? 

Here are some situations that might warrant a solar battery repair -

• The damage is minor or external, such as corroded terminals or loose connections.

• The battery is relatively new and still under warranty.

• There’s a known issue with the battery management system (BMS) or inverter that can be addressed without replacing the battery itself.

• Software updates or recalibration might fix the performance.

In these cases, a professional must be consulted who can often identify and resolve the issue quickly. At Wescombe Electrical, we provide expert suggestions and fast turnaround for battery repairs, ensuring minimal disruption to your power supply.

When Is It Time to Replace Your Solar Battery?

Not all problems related to the solar battery can be fixed with a simple repair. Sometimes, you might need to opt for a solar battery replacement. 

Here’s what you need to know -

• The battery is past its expected lifespan, generally over 10 years old.

• It’s showing multiple signs of failure, and repairs won’t restore its original capacity.

• The technology is outdated, and a new battery offers significantly better performance and integration.

• Repair costs exceed 50% of replacement costs, making it financially feasible to upgrade.

• Safety concerns, such as overheating or swelling, make replacement a must. 

However, it is always advisable to take the suggestion of an expert before making any decision.

Cost Considerations: Repair vs. Replacement

It is true that repairing a solar battery is less expensive when compared to an outright replacement. Minor repairs can range from $230 to $1500, while complex repairs can go higher. On the other hand, a full replacement, including labour, may range from $2,000 to $15,000, depending on the battery type and system size.

However, sometimes cost alone does not matter while making a decision. It is better to weigh the long-term benefits of both options before making an informed choice. 

If you are not too sure about what to do, take help from a professional. Experts can diagnose the battery and offer the best solution for you. 

Maintenance Tips to Extend Battery Life

There are several tips you can adhere to in order to extend the lifespan of your battery. These are - 

1. Regular Cleaning: It is important to keep the battery terminals clean and free from dust, corrosion, or rust. For this, you can use a mixture of baking soda and water with a soft brush to clean terminals safely.
   
   

2. Check Water Levels (for lead-acid batteries): It is critical to regularly inspect and refill distilled water to maintain optimal electrolyte levels.

3. Avoid Overcharging: Use a good charge controller to prevent overcharging. Also, you need to protect batteries from deep discharges, which reduce their lifespan.

1. Store in a Cool, Dry Place: Heat can degrade battery performance. It is important to store the batteries in a well-ventilated, cool area, away from direct sunlight.

1. Inspect Connections: Check all wires and connections for looseness or signs of damage to avoid power loss and inefficiency.
   

2. Limit High Loads: Avoid connecting high-powered devices that exceed the battery’s rated output. This helps reduce strain and overheating, preserving the shelf life of the battery.
   

3. Use Compatible Inverters & Chargers: Mismatched systems can damage batteries. That is why it is imperative to always use components recommended by the battery manufacturer.
   

4. Monitor Battery Health: Use a battery monitor to track voltage, charge cycles, and performance. Keep in mind that early detection of issues helps extend life.Wescombe Electrical: Your Go-To Partner For Solar Solutions
