Used Solar Panels: Everything You Need To Know

Are you looking for some of the lowest prices on solar panels? sites like eBay can be a great option. Many people post their used solar panels for sale at a discounted price there. Let's dive into the used solar panel market and see if buying panels from a reseller is the best choice for your home solar power setup.

What Counts as a Used solar panel?

A used solar panel is any panel that was previously owned by a person or business, usually a utility company. A solar panel that was purchased, taken out of the box, and never installed on a rooftop is still considered used.A solar panel that's "like new" is barely used and works just as well as a new one. One perk of buying a used solar panel is that it's usually cheaper.

Actually, not all used solar panels are equal. You need to know which items are worth buying. Finding a used solar panel is easy if you know what to look for. All you need to pay attention to is a realistic list of features or standards that you want to have in used solar panels. Apart from that, patience in waiting for the right seller.

How Much Do Used Solar Panels Cost?

So, when you're looking at second-hand solar panels, the go-to pricing method is the cost per watt. It’s like how they price new ones. Especially, you’ll find used panels going for anywhere between $0.10 to $0.60 per watt. That range depends on how old, shape, and the brand.

But here's the catch. Just because used panels are cheaper doesn't mean they're in good condition and free of issues. A lot of these panels are still in good shape, usually around 1-9 years old with pretty high efficiency rates. Besides the upfront cost, it’s smart to check out how much life they’ve got left and if there’s any warranty left on them before you make your pick.

Where you buy and who you buy used panels from, also matters. If you're getting from a trusted source or a seller with a good reputation, you might not worry. It's all about balancing cost with trustworthiness.

Why Might You Consider Buying Used Solar Panels?

Although used solar panels can work well for certain projects, they often come with more challenges than benefits for most solar customers. These are few reasons why used panels maybe not be the best choice for you:

Cost Savings

The cost of used solar panels is a critical factor to consider before buying. You should steer clear of the panels that are priced very low. This is because, in such cases, the seller could be trying to hide worn-out cells, decreased power output, or damaged wiring.

Reason for Selling

Understanding the reason for selling can provide a glimpse into the overall condition of the solar panel. For instance, if the reason to sell the product is to switch to a more robust panel, chances are the product is in good condition. However, if the owner is selling the panels to buy the new one of the same model, probably the product is damaged.

Length of Service

Length of service refers to the time for which the solar panels were generating electricity before selling. Generally, a panel that has run for a short service period means it'll have a few worn-out parts and more lifespan remaining. Hence, it's better to consider panels with a short length of service.

Warranty

Refurbished or used solar panels usually don't have manufacturer's warranty. But if they do, it is important to know how much of the warranty period remains.

Any Damages or Imperfections

A solar power system is exposed to all sorts of weather conditions ranging from high temperatures to cold winds. Rain, dust, high temperature, and debris can damage the outer surface of panels and reduce their efficiency.

That's why it's vital to analyze cracks, broken PV cell connections, and moisture signs below the cover. Always remember not all damages are visible. Some imperfections, like high moisture build-up, can be hidden, but they can highly affect the longevity of panels.

Remember, buying used solar panels comes with its own set of risks. However, understanding the five crucial factors will help you choose the system that lasts long.

Refurbished vs Used Solar Panels

When you consider buying used solar panels, there are used or refurbished options. Used ones have had previous owners, which could be a homeowner or business. Then refurbished solar panels have good condition by a fix-up crew or the original maker.

Let’s break down the big differences between used and refurbished solar panels to help you know what is best for your home and budget:

Performance

• Refurbished panels usually perform almost like new because they’ve had any bad or worn parts swapped out. But they might not have the same lifespan as brand-new panels.
• Used panels might show some wear and tear and could perform a bit less.

Cost

• Refurbished panels are often cheaper than new. They cost more than used panels because they’ve been fixed up nice.
• Prices for used panels can vary a lot. It depends on their condition. some look almost new, others have seen some wear. Make sure you know what shape they’re in before you buy.

Warranty

• Some refurbished panels have a warranty, but it’s usually shorter than new panels, like three months to nine years, or some might not have one at all.
• Warranties for used solar panels typically stay with the panel, so if you buy a home with them, you might inherit the warranty. However, if you purchase used panels online or from a marketplace, they often won't come with a warranty because sellers usually acquire them from previous owners without one.

The Drawbacks of Used Solar Panels

Buying anything used has its limitations. Used solar panels can be good for both the environment and your budget, especially if they're in good shape. However, there's always the risk when you're choosing used panels.

1. Used Panels Have Already Degraded
   Used solar panels often generate less energy than their advertised capacity because, over time, their output naturally decreases. This doesn't always indicate damage. It's just a normal result of wear and tear. However, if you start with higher initial output, you'll likely save more in the long run with your solar energy setup.
2. Used Panels Are Often Damaged
   Large commercial solar projects sometimes include damaged panels, which owners sell at a discount to mitigate losses. If your used damage solar panels, they'll generate less energy, resulting in reduced savings on your electricity bills. Damaged panels are less efficient at converting sunlight into electricity, meaning they produce less power compared to new, more efficient panels of the same size, under similar conditions.
3. Solar technology is continuing to improve
   The solar industry is always moving forward. The industry brings out new panel technologies at competitive prices. Even if a used panel is in good shape and just a few years old, it might not be as efficient as the latest models with updated technology.
   That’s why investing in newer solar panels is more efficient. Even with the higher cost, it can actually save more money in the future than buying a cheaper one like the older model.
   For example, most new solar panels installed today are monocrystalline. It means they include solar cells made from a single crystal of silicon. Also they are more efficient. Meanwhile, used solar panels installed polycrystalline, with solar cells made from many silicon fragments and tend to be more affordable. You will want to weigh options to fit your needs best? an experienced installer can help you before purchasing.
4. Used panels may not include warranties
   When we buy a solar energy system, it’s good to look at the warranties offered. These usually cover both the production and the equipment. These warranties ensure your panels remain defect-free and maintain a specified percentage of their original output.
   For instance, SunPower's top-tier warranty guarantees 98 percent of the original output by the end of the first year and 92 percent by year 25 for new installations. However, purchasing used panels can be risky as they often lack these warranties, leaving you vulnerable to lower solar production or complete failure without any coverage. Moreover, verifying the functionality and output of used solar panels can be challenging, potentially resulting in the purchase of broken or unusable equipment.
5. Used equipment might not qualify for incentives
   Many governments and utility companies offer great perks to encourage folks to switch to solar power. These can be rebates, tax credits, or even net metering programs
   It's important to know that these incentives usually come with specific criteria. For instance, some programs may mandate new equipment, a minimum efficiency rating, or certification from an approved installer. This means used panels might not meet the requirements to qualify for these benefits.

Factors to Consider Before Buying

Used solar panels can be an option, but careful planning is essential. Here are some factors that you have to consider before choose:

1. Age and Condition
   Start by considering the age and condition of the panels. Look for ones that are less than 10 years old to maximize their remaining lifespan and ensure they are free from cracks, hotspots, or corrosion, which can affect performance and safety
2. Performance History
   It's also important to ask about their performance history. Ideally, you should obtain documentation of past energy production or maintenance records to gauge their reliability and efficiency over time.
3. Seller Reputation
   Next, look into who you're buying from. Read reviews and ask questions about the panels to make sure you're getting them from someone trustworthy.
4. Certification and Standards
   Certification and standards are also key considerations. Make sure the used panels meet today's safety and performance standards, like those from organizations such as UL (Underwriters Laboratories). This ensures they are safe and compatible with your existing solar setup or any planned installation.
   Lastly, consider practical tips like getting the panels inspected by a qualified solar professional before making a purchase. Used panels may not come with warranties or may have shorter ones compared to new panels, so factor this into your decision. Research if they qualify for any government or utility solar incentives in your area to maximize savings and benefits.

Where to Find Used Solar Panels

If you're considering used solar panels, here are some places to search for:

• Online Marketplaces: Several websites specialize in selling used PV panels. They offer detailed information on age, brand, condition, and efficiency.
• Local Classifieds: Your local community can be a goldmine! Check online classifieds or community boards for people selling panels from residential or small commercial systems.
• Commercial and Residential Sellers: Companies upgrading their solar systems often sell their used panels. Contact local solar installers or businesses that recently went solar to see if they're selling their old panels.

Remember, wherever you find them, always prioritize the factors we discussed earlier when evaluating used solar panels. With a bit of research and caution, you can find high-quality used panels and invest wisely in your solar setup.
