There are many reasons to consider purchasing used solar panels and there are also a few  reasons not to buy used panels.

First, let's look at the reasons you would want to consider used panels in your home solar power system.

1. Using good used solar panels will decrease tremendously the up-front cost for installing your system.  A new home solar power system can cost you well over $20,000, depending on the size of the house.  In a lot of cases this makes installing solar energy cost prohibitive.
   
2. Solar panels that are in good condition tend not to lose a lot of their energy output over the years, even if they have been in the sun producing energy the whole time. Solar panels that are in storage do not degrade so if you luck up on some that have been stored, that could be a goldmine for you.
   
3. Used solar panels that are slightly damaged can be picked up at a fraction of the cost of new and in some cases can be easily repaired, at a nominal cost. Things such as loose connections and even broken glass (in some cases) might be the best deal for you since you will get a bargain for a non-working panel that won't cost you very much to fix.
   
4. Since the up-front investment required for a new solar energy system is cost prohibitive for most people, locating and purchasing used panels can help you get started with your home system when you otherwise might not be able to. You'll be able to get off the grid sooner and become energy independent!

Of course, we can't state the pro's without looking at the flipside.

1. If you have no idea about how to choose a good used solar panel and you don't have anyone to assist you, it may not be in your best interest to do this. Buying a solar panel that is too costly to repair is never a good deal.
   
2. Older solar panels are larger than the new models and take up more space. If you have limited space available, used solar panels may not be an option for you.
3. Depending on the extent of the damage, the panels may be too costly to fix or the energy output may be so low that it's not worth the trouble.

Spend time researching used solar panels so that you get the best panels at the best possible price.  There are many places that specialize in used panels, but make sure that they have a money back guarantee in case the panel does not work or cannot be repaired to your satisfaction.

If you’ve been considering buying used solar panels for use in your home or business, there are some important things you need to know before you begin. Just follow these five tips for determining how to go about choosing a good used solar panel.

1. An important factor when you start your search for used solar panels is making sure that you know what to look for. The reason why this is important is because you want to choose a solar panel that will work and be a true value. If you don’t know what to look for, then you run the risk of buying a damaged panel that will never work properly or give you the energy output you need.

2. Another important consideration for purchasing used solar panels is where you purchase your panels.  If you have a resource close to your home where you can physically inspect and test the panels, that is the ideal situation.  Otherwise, you have to rely on the information provided by the seller.  If you do purchase a panel online, make sure that the return policy is in place just in case the panel does not work.  A reputable seller will always offer a money back guarantee if not satisfied. If you make sure that you can return the panel(s) in case you are not satisfied, then you’ll be fine.

3. You don’t have to buy a panel that is in perfect working order in order to get a great value. All you need to do is to choose one with little or no damage, and make sure that you know the extent of the damage.  Some things like cracked glass and loose connections can easily be repaired at very little cost.

4. Instead of complicating your home solar power system efforts by choosing a non-working panel or one that is too expensive to be repaired, try it this way: locate the used panel, and then test it with a multimeter in bright sunlight to ensure it's a working panel. In fact, if you are purchasing a unit online, then you can have the seller take a picture of the unit hooked up to the multimeter showing the reading.

5. If you're looking to save money but you're concerned about the quality and price of used solar panels, building your own solar panels could be a great alternative for you.  It’s not as difficult as you might think. All you need to do is purchase a video course that walks you through each step of the process.  In either case, you will save an incredible amount of money versus buying a new system from a solar system supplier.

So if you really want to buy used solar panels, follow these tips to ensure you make an informed decision when purchasing the panels.
