solar battery
Solar energy is getting more popular every year. More homes and businesses are using sunlight to power their lights, appliances, and even cars. One important part of any solar system is the solar battery. This battery stores extra energy during the day so you can use it at night or when it’s cloudy.
But there’s something very important that many people don’t hear about from their supplier: solar battery degradation. That means the battery slowly becomes weaker over time.
This is not always explained clearly when people first buy their solar system. A solar energy equipment supplier Centennial, focuses only on the exciting parts, like saving money or helping the planet. But understanding battery degradation is just as important, because it tells you how long your battery will really last and how well it will work in the future.
What Happens Inside a Solar Battery? Ask a Solar Energy Equipment Supplier Centennial
Let us first cover the foundations. Like the batteries in your phone or tablet, a solar battery operates largely under your solar panels convert sunlight into power when it gathers on them. Your house gets some of that power. The remaining is kept in the battery for use later.
Every time your battery charges up and then sends energy back out, it goes through something called a cycle. Over time, these cycles cause tiny changes inside the battery. After hundreds or thousands of cycles, the battery can’t hold as much energy as it used to. This is called degradation.
Think of it like a sponge. At first, the sponge can soak up a lot of water. But after many uses, it starts to wear out and can’t hold as much. Solar batteries are the same way.
Why Doesn’t Everyone Talk About This?
You might wonder: if this is so important, why don’t all suppliers explain it?
Well, many solar companies also want to keep things simple and focus on the benefits. They may talk about:
- How much money will you’ll save
- And, how clean energy helps the planet
- How you’ll still have power during a blackout
These things are true, and they are great. But if you don’t know how your battery will age, you might expect it to work the same way forever. Also, that’s just not realistic.
Note: A good battery will still work for many years, but it won’t stay at 100% forever. You need to know what to expect.
How Fast Do Solar Batteries Wear Out?
Different batteries wear out at different speeds. Usually, though, most batteries lose between 2% and 5% of their capacity annually. Your battery might thus only store nine units in a few years, even if it stores ten units today.
This might not sound like a lot, but it adds up:
- After 5 years, your battery might hold 85–90% of what it did at the start.
- After 10 years, it might be down to 70–80%.
This doesn’t mean your battery is “bad.” It just means it’s getting older and not as strong. Just like an old phone that doesn’t stay charged as long, your battery is doing its best, but it’s not new anymore.
Tip: Always ask how much energy your battery will store after 10 years—not just when it’s new.
What Makes Batteries Wear Out Faster?
Some things make batteries age more quickly. Here are a few:
- Heat: Batteries don’t like to get too hot. If your system is in a warm area, this can speed up wear.
- Full discharges: Using all the energy in your battery every day puts more stress on it.
- Poor setup: If your battery isn’t installed correctly or doesn’t have good airflow, it may wear out faster.
- Cheap parts: Low-quality batteries and inverters (which control power flow) can cause more harm than good.
Quote: “A battery is only as strong as the system that supports it.”
What a Good Solar Company Should Tell You
A helpful solar energy company Centennial should do more than sell you a system. They should:
- Explain how batteries age
- Show you how to check battery health
- Offer regular check-ups
- Give you tips to help your battery last longer
Sadly, not every company does this. That’s why you need to ask questions and choose a team that’s honest and experienced.
Simple Ways to Protect Your Battery
You don’t need to be a scientist to take care of your solar battery. Here are easy things you can do:
- Don’t drain it all the way every day. Try to use only 70–80% of the energy inside.
- Keep it cool and clean. If it’s in a garage or shed, make sure it has airflow.
- Check on it now and then. Some systems let you use an app to see how your battery is doing.
- Use strong, modern batteries. Newer types like lithium iron phosphate (LiFePO4) last longer than older kinds.
One Search Isn’t Enough
Many people go online and search for something like “solar installation near me”. They find a local installer, get a quote, and make a quick decision. But just because someone is nearby doesn’t mean they’re the best choice.
It’s important to:
- Ask about battery life and degradation
- Check if they have experience with your type of system
- Find out what kind of support they offer after the system is installed
Your battery is a long-term investment. You need someone who understands how to make it last, not just someone who can put panels on your roof.
