The Ultimate Guide to Used Solar Panels

Solar panels have gained immense popularity in recent years as a clean and renewable energy source. While new solar panels are widely available, used solar panels have also become a viable option for those looking to harness solar power without breaking the bank. In this guide, we will delve into the world of used solar panels, exploring what they are, their costs, considerations when buying them, comparing them to refurbished panels, and determining if they are suitable for your needs.

What is the Used Solar Panels?

Used solar panels are photovoltaic (PV) modules that have been previously installed and operated but are still in working condition. These panels are often available for purchase in the secondary market when individuals or businesses upgrade their solar systems or remove them due to relocation or system expansion.

Here are notable pros and cons of used solar panels:

Pros of Used Solar Panels:

Cost-effectiveness: Used solar panels can be significantly cheaper than new ones, making them an attractive option for budget-conscious buyers.

Environmental impact: By reusing solar panels, you contribute to reducing electronic waste and extending the lifespan of renewable energy systems.

Availability: Used solar panels offer a wider variety of models and brands compared to the limited options available for new panels.

Cons of Used Solar Panels:

Reduced efficiency: As solar panels age, their efficiency gradually decreases. Used panels may not generate as much electricity as newer counterparts, leading to slightly lower energy production.

Warranty limitations: Used solar panels may no longer be covered by the original manufacturer's warranty or have limited warranty options. This can increase the risk associated with potential repairs or replacements.

How Much Do Used Solar Panels Cost?

The value of used solar panels is typically determined by their cost per watt, generally ranging from $0.10 to $0.60 per watt. However, there are also several factors that influence their price, including their age, condition, brand, and power output. On average, used solar panels can be purchased for around 50% to 70% of the price of new panels. It's important to research and compare prices from reputable sellers to ensure you're getting a fair deal.

What to Consider When Buying Used Solar Panels?

When buying used solar panels, there are several crucial factors to consider to ensure a successful and reliable purchase:


Carefully assess the condition of the panels. Look for any visible damage, such as cracks, delamination, or hotspots. Inspect the frame, connections, and junction boxes for signs of wear or corrosion. It's advisable to physically inspect the panels or request detailed photographs.

Performance and Efficiency

Inquire about the panels' performance history and efficiency ratings. Ask for information about the power output and degradation rate over time. Panels with higher efficiency ratings will generate more electricity and provide better long-term value.

Age and Usage

Determine the age of the panels and their previous usage. Older panels might have a shorter remaining lifespan and lower performance. Inquire about the installation date, operation duration, and any maintenance or repairs performed.

Brand and Manufacturer Reputation

Research the brand and manufacturer of the panels. Established and reputable manufacturers often provide higher quality and longer-lasting products. Look for reviews, certifications, and industry reputation to gauge the reliability of the panels.


Check if any warranty is still valid for the used panels. Some manufacturers offer transferable warranties, ensuring protection against defects or performance issues. Review the warranty terms and coverage duration, if available.


Ensure that the used panels are compatible with your existing or planned solar system. Consider factors such as voltage ratings, connector types, and mounting requirements. Incompatible panels may result in inefficient energy production or require additional expenses for system modifications.

Seller Reputation

Purchase from reliable and reputable sellers. Research their track record, customer reviews, and ratings. Ensure that the seller has a good reputation for selling functional and reliable used solar panels.

Price and Cost Analysis

Compare prices from multiple sellers to determine a fair market value for the used panels. Take into account the condition, age, brand, performance, and warranty coverage. Evaluate the cost savings compared to new panels while considering the long-term financial benefits of solar energy.

By considering these factors, you can make an informed decision when buying used solar panels, ensuring that you invest in panels that are in good condition, compatible with your system, and provide reliable performance for years to come.

Comparison of Used Solar Panels With Refurbished Solar Panels

Used solar panels are simply pre-owned modules, while refurbished solar panels undergo a more rigorous reconditioning process. Refurbished panels are thoroughly tested, repaired if needed, and brought back to a near-new condition before being resold. Here's a comparison between used and refurbished solar panels:

Used Solar Panels:

  • Lower initial cost
  • Varying levels of wear and tear
  • Potential limitations in warranty coverage
  • Slightly reduced efficiency compared to new panels

Refurbished Solar Panels:

  • Higher initial cost compared to used panels
  • Thoroughly tested and repaired to near-new condition
  • Often accompanied by warranties
  • Improved efficiency and performance compared to used panels

Deciding between used and refurbished panels depends on your budget, required performance, and the level of risk you are willing to accept. Refurbished panels offer a higher level of assurance but come at a higher price point, while used panels offer cost savings but may have slightly lower efficiency.

Are Used Solar Panels Suitable for You?

Used solar panels can be an excellent option for certain individuals and situations. Here are factors you to consider when determining if used panels are suitable for you:

Budget: If you have budget constraints or want to save on the upfront costs of a solar system, used panels provide a more affordable alternative to new panels.

Long-term goals: Consider your long-term energy goals. If you plan to upgrade or expand your system in the future, used panels may be a cost-effective solution to start with.

Location and energy requirements: Assess your location's solar potential and your energy consumption needs. Whether used panels provide sufficient energy output depends on your location's solar resources and electricity demands.

Technical knowledge: If you have experience with solar systems or access to professional assistance for installation, maintenance, and repairs, used panels can be a viable option.

However, if you prioritize maximum efficiency, extensive warranty coverage, or want the latest technology, investing in new or refurbished panels might be more suitable for your needs.
