Cost can be an issue when installing solar panels. Resourceful homeowners may look for ways to get in the door by buying discounted or used solar panels. If you can find solar panels that work well but cost less, why not? Whether used or new, all solar panels work using the same basic principals. Purchasing used and discounted solar panels may be a good option for homeowners looking to go solar on a budget. However, there are risks and precautions involved. We’ll take a look at some of the Pros and Cons of buying used panels. But first, where do you get them?

Discounted panels often come from industrial, commercial, and manufacturing firms that regularly update their product lines. In the process, older models are sold to used solar panel dealers. Rumor has it that some older models are even discarded or given away. If you can find a freebie, all the better, as long as it’s in good working condition!

Used panels become available when businesses or homeowners upgrade their systems. Several companies sell discounted, pre-owned modules and module racks on their websites, such as The Solar Biz, NexTag, and Sun Electronics, which sells blemished and/or refurbished panels and inverters. Many manufacturers will have a surplus inventory, selling older models at a discount to make room for newer models. Finally, you can look for a resource such as Wholesale Solar that sells solar panels wholesale.

Now that you know where to get used or discounted panels, should you go that route? Perhaps this list of advantages and disadvantages will help you make that decision.

Pros

• Even an older solar panel may produce power at levels close to that of its peak operating years.
• A cheaper solar panel may generate less power per foot, but will cost less for additional modules that help make up for lost power. In this case, roof space should be taken into consideration as well.
• Companies should be willing to test used equipment before you purchase it. This is a good way to make sure everything is in working order. At the same time, find out where the solar panel came from, what the environment was like there, and how old the panel is. In this manner, even if your panel is used, you can find a good deal based on a little research.
• Used solar panels can be purchased with a warranty or money back guarantee.
• Some loose wire connections can be easy to reconnect with soldering. Make sure you check all the connections and whether or not they are fixable.

Cons

• Solar grants require the purchase of new equipment.
• According to Solar Expert Paul Smith, used panels may not come with a manufacturer’s warranty and risk being older than they look. As an alternative, Smith recommends taking advantage of state and federal tax rebates that recover up to 50 percent of the cost, as well as purchasing package deals from reliable solar installers who receive the best solar technology equipment and understand how it all works. In addition, smaller systems are more affordable and less of a risk. You can always enlarge it later.
• Solar panel discounts may come from retail home improvement chains with comprehensive packages. If this includes installation, you may be compromising discounted panels at the risk of poor installation. Selecting a solar installer is a big part of achieving an optimal system, however, and quality in this department should never be compromised. In a recent interview with CalFinder, REgrid Power CEO and SolarTech.org Chair Tom McCalmont warned homeowners against contractors who don’t exclusively install solar systems. “Generally, the best solar contractors do solar designs and installations exclusively,” he says. “Electrical contractors may specialize in other types of electrical work, but they generally do not have the expertise to do correct solar assessments and designs.”
• Used solar panels can come with a long list of potential imperfections, such as cracks in the glass, condensation under the glass, and broken connections. Other imperfections can be found at Used Solar Panels.
