When it comes to installing a new solar energy system, the costs can be a bit daunting. Solar panels, inverters, batteries—these components add up quickly, and while the long-term savings are undeniable, the upfront investment might not something everyone can comfortably afford.
Used solar panels offer a cost-effective way to tap into renewable energy. They allow you to take advantage of solar power without the hefty price tag that comes with new equipment. Whether you're simply looking to save money or you're a DIY enthusiast working on your own solar project, second-hand panels can offer both flexibility and affordability. In fact, they’re becoming an increasingly popular choice for people who want to benefit from solar energy without breaking the bank.
What Are Used Solar Panels?
Used solar panels are simply panels that have been previously installed and are now being resold. These panels can come from a variety of sources, such as residential or commercial systems that have been upgraded, decommissioned solar farms, or even surplus inventory from manufacturers. Essentially, any solar panel that has been in operation or has left its original packaging can be considered "used."
One key characteristic of Old solar panels is that they will show signs of wear and tear, such as slight discoloration, scratches, or dirt. Despite these cosmetic issues, many old solar panels still function well and can provide years of energy production. They won’t perform at the same efficiency as a brand-new panel, as solar panels lose some efficiency over time.
Types of Used Solar Panels: Second-Hand vs. Refurbished
When it comes to used solar panels, there are two main types to consider: second-hand and refurbished.
Second-Hand Solar Panels
Second hand solar panels are exactly what they sound like—panels that have been removed from a previous installation and are resold in the condition they were taken down. These panels may show signs of age or wear, but they haven't undergone any repairs or maintenance.
Refurbished Solar Panels
Refurbished solar panels, on the other hand, have been restored or repaired to improve their functionality. These panels have been inspected and tested by a professional, with any faulty components replaced, ensuring they work as close to new as possible.
Here's a table that compares second-hand and refurbished solar panels based on key factors:
| Feature | Second-Hand Solar Panels | Refurbished Solar Panels |
|---|---|---|
| Cost | Lower price, more affordable | Higher price due to inspection and repair costs |
| Condition | Varies widely; may have wear and tear | Inspected, cleaned, and repaired to near-new condition |
| Performance | May have reduced efficiency and output | Restored to near-original efficiency and performance |
| Warranty | No warranty | Comes with a limited warranty |
| Lifespan | Shorter lifespan due to prior usage | Longer lifespan after refurbishment |
| Risk | Higher risk due to unknown condition and potential damage | Lower risk with tested and restored performance |
| Availability | Readily available from various sources | Less widely available, depending on the refurbisher |
| Suitability | Suitable for budget-conscious buyers | Best for those seeking reliable, restored performance |
Which Option Is Best for You?
Choosing between second-hand and refurbished solar panels depends on your budget, energy needs, and risk tolerance.
- Second-hand panels is a good option if you are on a tight budget and are comfortable with the potential risks of shorter lifespan and uncertain performance.
- Refurbished panels are a better choice if you want a more reliable product with a longer lifespan, especially if you are willing to invest a little more upfront for peace of mind and better performance.
How Much Do Used Solar Panels Cost?
Price is undoubtedly one of the most attractive reasons for second-hand solar panels. The average price of a used solar panel is between $0.05 and $0.60 per watt, which has a lot to do with the brand, condition and age of the panel. Here is a screenshot of our second-hand solar panel prices at Shopsolarkits: The cost price of 12 solar panels is $779-629, which translates to $65-52 per used solar panel. Although the price varies from store to store, the overall price range will not differ too much.
Where Can You Buy Used Solar Panels?
If you're interested in purchasing used solar panels, there are several places where you can find good deals. The market for second-hand solar equipment has grown, offering more options for buyers looking to save. Here are a few popular platforms to explore:
-
eBay – One of the most well-known online marketplaces, eBay offers a wide selection of second-hand and refurbished solar panels. Sellers range from individuals selling panels from personal systems to companies clearing out surplus inventory. Just be sure to check seller reviews and ask questions before making a purchase.
-
Craigslist – A local classifieds platform, Craigslist can be a good source for finding used solar panels at lower prices. It's important to inspect the panels in person before committing to buy, as the platform doesn’t offer much buyer protection.
-
Facebook Marketplace – Similar to Craigslist, Facebook Marketplace allows individuals to buy and sell items locally. It’s a great option for finding second-hand solar panels in your area, often at discounted prices. Again, always arrange to see the panels and check their condition before purchasing.
-
Specialty Solar Equipment Websites – Some websites, like SolarBiz or Santan Solar, specialize in selling new, used, and refurbished solar panels. These platforms often offer more transparency and customer support compared to peer-to-peer sites, making them a safer bet for quality second-hand panels.
-
Solar Installers – Some solar companies or installers may sell used panels when they upgrade systems or remove old installations. It’s worth reaching out to local installers to see if they have any used or surplus panels for sale.
Key Considerations When Buying Used Solar Panels
Purchasing used solar panels can be a great way to save money, but there are a few key factors to consider before making your purchase. Here are some things to keep in mind:
Efficiency Degradation
On average, solar panels lose about 0.5% to 1% of their efficiency per year. When buying used panels, it’s essential to find out how old they are and what their current efficiency rating is. A 10-year-old solar panel will be 10-15% less efficient than a brand new one, which means you’ll need more solar panels to generate the same amount of electricity.
Reduced Lifespan
Most solar panels have a lifespan of about 25 to 30 years. If you're purchasing used panels that are already 5, 10, or even 15 years old, their remaining lifespan will significantly reduced. This is an important factor to consider, especially if you're planning a long-term solar installation. The shorter lifespan will reduce the long-term savings you'd get from using solar energy.
Expired Warranty
One of the biggest downsides to buying used solar panels is that they often come without a warranty. Most manufacturers offer warranties for around 25 years on new panels, but once they’re sold as second-hand, the warranty no longer apply. Without a warranty, if something goes wrong with the panels, you’ll have to pay out of pocket for repairs or replacements.
Ineligibility for Incentives
In many cases, second-hand solar panels do not qualify for government incentives, tax credits, Or the rebate you get when you buy a new panel. These incentives can significantly reduce the overall cost of going solar, so missing out on them will impact the overall value of choosing used panels.
Condition of the Panels
Used solar panels can sometimes come with physical defects such as cracks, scratches, or damage to the glass or frame. These issues can affect the panel’s performance and longevity. Be sure to inspect the panels thoroughly or request detailed photos and descriptions from the seller before making a purchase.
Are Used Solar Panels Worth It?
| Pros | Cons |
|---|---|
| Significantly cheaper than new panels | Reduced efficiency due to age |
| Good for DIY or short-term projects | Shorter remaining lifespan |
| Environmentally friendly, reduces waste | Likely no warranty |
| Quick availability from multiple sources | Ineligible for incentives and rebates |
| Ideal for smaller or off-grid systems | Possible physical wear or damage |
When Used Solar Panels Are Worth Buying
If you're working on a DIY project or just need a short-term solar installation, used panels are an excellent choice. The significant cost savings, plus the fact that many used panels still have years of use, make them ideal for projects like powering a cabin, RV, or even an off-grid garden shed. But If you plan to connect your solar system to the grid, you may face some challenges. Your utility company will typically require a licensed electrician to sign off on your solar system, confirming that it meets the necessary standards, before allowing you to connect to the grid.
Additionally, for environmentally-conscious buyers, opting for used solar panels can help reduce waste, giving these panels a second life rather than sending them to a landfill. It’s a practical way to go green without breaking the bank.
When It’s Better to Buy New Panels
On the other hand, if you're looking for a long-term investment in solar energy, such as powering your home for decades, it's usually better to purchase new panels. New solar panels come with warranties, are more efficient, and qualify for incentives like tax credits, which can significantly reduce your overall cost in the long run. Plus, with new panels, you’ll be able to enjoy the latest advancements in solar technology, ensuring you get the best performance possible for the long haul.
