Top Tips From AZ Solar Companies: What To Look For When Buying Used Solar Panels
There are many ways to decrease your energy bills and make your home more Eco-friendly. One of the best ways to do this is to invest in solar electric panels. While they are one of the more expensive energy-efficient products on the market they drastically reduce electricity bills.
The cost of solar panels went down a staggering 40 percent over the last year and continues to fall. While they are much less expensive than before, they can still be a high priced asset for many homeowners. If you have considered buying solar panels only to be put off by their high prices then you may want to consider buying used solar panels.
Arizona solar electric companies say that used solar panels are actually a really good investment because they still retain approximately 90 percent of their ability to convert light energy into electricity. They are able to do this even after 20 years which means that you could still have a used product that works great. Most solar panels have life expectancies of about 40 years or more which makes them perfect for buying used.
AZ solar companies do however suggest that you look out for these three things when searching for used solar panels:
- Cracks or breaks in the surface of the glass
- Loose connections especially within the solar cells
- Condensation build up under the glass
These defects are pretty easy to spot if you just take a good look at the product. They are also the most common problems with used solar panels. On top of looking for these defects, make sure that before you ever buy used solar panels you test them out. While many solar panels still retain most of their ability to convert energy, you never want to take a chance on buying used solar panels that are under par so it is extremely important to test the solar panel’s power output.
Also, remember that older solar panels tend to be larger in size. Make sure that you measure the amount of space you have on your roof when looking for older solar panels. Older solar panels are larger because they need more surface area to create the same amount of energy as newer models, and you should make sure beforehand that you actually have room for them on your roof.
