Should I Buy Second Hand Solar Panels?

The Benefits of Used Solar Panels

In an ideal situation, used panels will provide many of the same benefits as new systems. Some of these benefits are as follows:

• Energy Security. Most people have nowhere to turn when the electric grid goes down. Solar panels provide a reliable energy source during emergency situations.
• Reduced Electric Bills. More of an investment than an expense, solar panels often pay for themselves over time.
• Increased Home Value. Appraisers tend to view solar panels favourably. Additionally, many buyers are becoming more environmentally conscious, raising the demand for solar.
• Energy Cost Protection. Solar panels protect against rising energy costs.

Aside from the usual benefits, the cost of a used solar panel system tends to be much lower than that of a new one. In fact, some used systems may even cost half as much as new ones.

 

How Much Does It Cost?

The cost of used solar panel systems varies depending on several factors. Theses factors include the following:

• The type of panel
• The age of the system
• The size of the system
• The condition of the parts

Keep in mind, however, that just because the upfront costs of a used system seem lower does not mean that it is free of additional costs.

First, due to years of exposure to the elements, most used panels experience some wear and tear. This means that there will probably be some repair costs involved, as well as more maintenance costs down the road.

Second, you may have to purchase a new inverter as well. This can be one of the more expensive parts of a system, so it is important to consider this when choosing between buying new or used.

Third, you will likely have to hire an MCS accredited installation specialist to get your system up and running.

Also, consider using the price per watt rather than the price of the unit to compare solar panel systems. This method will provide you with the most insight.

 

Where Can I Buy Used Solar Panels?

A few of the best places to look for used systems are online marketplaces such as eBay, Craigslist, and Gumtree. However, you should also check your local classified section.

If you choose to buy online, pay really close attention to the seller’s rating, as this can tell you a lot about their trustworthiness.

You want to make sure they answer your questions truthfully. Also, if you can, choose a seller that lets you test the solar panels before buying.

Aside from purchasing used panels from online sellers, you can also look into surplus solar panels. These often come at a significantly discounted price.

Much like used solar panels, surplus solar panels will be older models, but they have less wear and tear than your standard used system.

 

Things to Pay Attention to When Buying Used

You should definitely take more precautions when buying a used system than when investing in a new one. Doing so can save you a lot of grief.

When shopping for used solar panels, the first thing you should check for is damage. Look for any signs of moisture, cracks, or burn marks in the solar panels. While minor issues like cracks are repairable, you will have to decide whether investing time and money to make these repairs is worthwhile for you.

Next, pay close attention to loose wires and connections. These may be harder to notice at first, but they can cause your solar panels to perform less efficiently. The good news is that a solar panel with loose connections may still be salvageable, but you will need a soldering iron to fix it.

Before purchasing, always use a multimeter to test the voltage and amps of the solar panel system. Find the converter box on the backside of the solar panel, and make sure you set your multimeter to read a higher voltage than the panel’s rating. When you measure the amps, make sure the panel is out of the sun before attaching the clips.

Another smart approach to take is to look for panels that are still under the manufacturer’s warranty. This will provide you with a safety net in case something goes wrong.

 

The Pitfalls of Used Solar Panels

There are several pitfalls of used systems that you should be aware of.

One of the biggest pitfalls is that owners of used systems cannot take advantage of the Feed-in-Tariff incentive. Only new installations carried out by certified MCS specialists are eligible for this program.

Additionally, you should also know that used systems tend to have much shorter lifespans than new ones. Not only that, but older solar panels can be much less efficient.

Also, as mentioned before, you will most likely need to hire a specialist to install your system. Installing a system without expert assistance is risky.

 

Are Used Solar Panels Worth It?

It depends on the individual. For some, the potential benefits that come with a used system outweigh the risks.

Remember, if you choose to buy used, avoid damaged solar panels unless you are both capable and willing to fix them. Be smart when choosing a seller, and perform your due diligence by testing the system before making your final decision.

By taking the necessary precautions, you may end up with a high-quality solar panel system at a bargain. Just make sure you are aware of extra costs that may come with it, such as installation and a new inverter.
