With proper care, solar panels can last 25 to 30 years. But even with the best care, solar panels will slowly lose their efficiency to convert sunlight into energy. But how do you know when to replace roof solar panels? How are solar panels replaced? If you’re looking for replacement solar panels, Atlasta Solar Center is here to help!
Signs It’s Time To Replace Your Solar Panels
Here are several signs to keep an eye out for:
Age
At around 20 years, most solar cells will perform to about 80-90% of their efficiency. Even with regular maintenance, solar panels will wear due to use and exposure to the elements. This loss in efficiency is called degradation. Solar panels degrade by about 0.3% to 0.8% per year.
Visible Wear and Tear
Any physical damage to your panels can negatively impact their performance. Extreme weather, hail, falling branches, fly balls, etc. can harm your panels. Be aware of any bending or cracks in the frame. Why? A damaged frame may allow water to infiltrate the solar cells, causing severe damage. If you notice any structural damage or broken glass, call us for an estimate on a solar panel replacement.
Energy Yield and Performance
One of the most obvious signs it’s time to replace your solar panels? Consistent low energy yield and performance, even after regular cleanings. A pattern of low energy yield can mean that your panels are aging and need to be replaced. Always check and compare your energy bills to know how your panels are performing.
Discolored Surfaces
A discolored surface can mean that water or another contaminant is affecting your solar panels. Anything that blocks the sun from striking the panels will decrease the amount of energy produced by your panels, so it’s best to have them replaced.
When Other Components of Your Solar System Fail
Have you inspected your panels and don’t see any problems? It’s possible that other components of your solar system may not be working. Other parts of a solar system include:
Inverter: This component converts solar energy from DC to AC power. Inverters typically last 10 to 15 years.
Solar battery: This stores the energy generated by solar panels. Battery banks last about 5 to 15 years on average.
Charge controller: this part component controls and protects the storage system from overcharging. The charge controller as the “brain” of the solar setup, as it controls the charge and current to the batteries. Charge controllers last about 15 years on average.
You can purchase these items individually. However, many solar panels come bundled as kits that include these items.
How Solar Panels Are Replaced
Here’s what to know about solar panel removal and replacement:
Solar Panel Removal
To safely remove panels, the system must be fully powered off first. The solar panels are then unplugged from one another and removed. This involves siding out the panels sideways. Then the mounting hardware is carefully removed, and so are any remaining cables and wires. Panel removal and replacement should always be performed by professionals only. If you try to remove panels on your own, you risk electrocution.
Solar Panel Replacement
Solar panels are replaced like a normal system solar installation. In general, this involves spacing apart and setting the mounts on the roof. Holes are drilled into the roof, and the mounts are secured with steel bolts. Solar panels are then fastened to the mounts, and the panels are connected to the electrical supply.
FAQs About Solar Panel Replacement
Here are several frequently asked questions about solar panel replacement:
Can I remove and replace or reinstall solar panels myself?
We highly recommend that solar panels are removed by certified professionals only. Why? We know how to safely remove and replace solar panels, so the job is done right the first time. At Atlasta Solar Center, we have years of experience and the right tools to install and replace solar systems. Don’t risk your well-being by attempting to move or replace solar panels on your own.
Removing panels on your own can also void your solar system’s warranties or contracts.
How can I extend the life of my solar panels?
First, have your solar system installed professionally. At Atlasta, we install quality solar products safely and efficiently. Any DIY installations are dangerous and unlikely to provide enough energy yield. Second, maintain your panels with regular cleaning. How to know when to clean them? Whenever your panels are dirty, clean them. Always power off the system before cleaning, and use a soft-bristled brush. Also, monitor your energy bills before and after cleaning, so you know when to clean next.
A professional annual inspection is a great idea as well. By contacting us to check your panels, we can resolve any current issues and prevent future problems.
Can I have my solar panels repaired instead of replaced?
It is possible to repair solar panels, but this really depends on the type and amount of damage. It’s generally recommended that rather than continue using a damaged panel, to have a new one reinstalled for best power yield.
Can bird poop damage my panels?
Besides looking gross, bird poop is acidic and can damage your panels over time. This is why it’s important to clean your panels whenever they are dirty, especially if there is bird poop. Don’t wait for bird droppings to accumulate on your panels.
What’s the longest-lasting solar panel?
Both monocrystalline and polycrystalline solar panels can last beyond their 25-year lifespans. Monocrystalline panels produce the highest energy yields of any solar panel and are the most expensive panel. Polycrystalline panels produce just 1% less power than monocrystalline panels and are less expensive than monocrystalline panels.
