Used solar panels can be found in many places and from different sources. You can approach homeowners who have solar panels that look old. You can also try your luck at recycling centers where broken solar panels can occasionally be found.

Yet the most effective way is to contact contractors or agents who specialize in solar panel installation. Many of them discard used solar panels before fitting new ones for their customers. Another source to get used solar panels are building contractors. They often renovate houses installed with photovoltaic panels and are glad to have someone dispose such items for them.

Most of these people may give you their used solar panels provided you offer to transport them away from the site. If they are unwilling to hand those pre-owned solar panels to you, try offering them a small fee that includes transporting the solar panels to your residence.

As you hunt for used solar panels, remember to look out for fatal flaws that may render your photovoltaic cells unusable. Here are some tips on what to look out for:

1. Cracked glass, condensation under glass and broken connections are common problems that cause owners to discard their solar panels. Fortunately there is a remedy for these failures.

2. Loose connections between solar cells may go unnoticed as you inspect them visually. Such faults can be picked up using a resistance meter, and joints with high resistance can be re-soldered together.

Although pre-owned solar panels are cheap, there are downsides to using them. One of the most obvious is the decrease in power output. After they are exposed to the sun for one or two decades, photovoltaic cells become less effective. Although marginal, you have to take this degradation into consideration, as you’ll need more solar panels as a result. Used solar panels also have a shorter lifespan, thus they can only serve you for their remaining years.

Needless to say, the low price of used solar panels allure many people to buy them. If the cost per watt can justify the purchase and they still have many more years to go, they can be excellent investments.

Therefore if you intend to install a used solar panel for your home, the payback period can be shorter than when you buy new ones. A trusted contractor is able to help you look out for used solar panels that are relatively and without damage. Therefore keep in contact with them, learn from them and build a relationship, and you’ll have a good-as-new solar panel at your home soon.
