Solar Panel Quality Matters!

Aug 09, 2013

The industry is at a crossroads...with the massive consolidation and the manufacturers fight for survival, PV quality has never been more important.  As an industry, we need to ensure quality is our top priority to ensure we keep the market's confidence. 


As a buyer, it is so important to remember that not all modules are the same.  In the last five years, we've seen an explosion of manufacturers, and the last two years have seen many of these manufacturers fail.   As a buyer, keep these thing in mind when purchasing modules.

  • Are the modules coming from an established, proven manufacturer?
  • Has the manufacture allowed third parties to test and analyze is product?
  • What is the reputation of the company?

Also, price can be an indicator.   Modules of the same quality will be +/- 10% in pricing.  If you find a significantly lower priced module, this should at least raise your awareness to do further investigation.  

Solar module testing has shown some modules only lasting a couple years (even though they had 20 year warranties), so it is important not to let the warranty fool you into believing the module is going to provide long term performance and reliability. 

Here are a couple of videos discussing quality...check them out.
