The Blog Responds Regarding Discoloration On Solar Panels

Last week I created a video on YouTube that I emailed regarding the discoloration that was found on 1 of my 55Watt solar panels I purchased from them a year ago. They responded today. Below is a transcript of their response to my question:

Robert S. Question:

Hi Alex or whom this may concern,

I made a YouTube video on my 3x 55watt solar panels I purchased from you all a year ago, and I noticed after checking on them a week ago that some of the solar cells appear to have some discoloration or some dark spots on them and I wanted to know if this is a problem or normal?

My subscribers are curious about your response to this as well.


UL-Solar’s Response:

Dear Robert

There is no problem if you have some stains on the solar panel. If you are getting output as before no worries, if you output is going down we will replace it immediately.
Remember you have 25 years warranty on each panel you buy from UL-SOLAR.

thank you

Additional Comments from UL-Solar:

Yes, no matter what you get on you solar panel, you get warranty, not on paper only but real time warranty. That’s why we have so many customer, return to us more an more.

After receiving this response from the manager of UL-Solar, I am more confident with my purchase and this solar company. So far they have done a great job with providing great customer support, and when I did have an issue with a solar panel I received from them, they quickly allowed me to return it and receive a brand new panel.

Many people have requested a written version explaining how to build a solar panel and solar power system, so I have published my book on the Amazon Kindle store. Part of the income made from the book will be used to help provide more prizes for the monthly solar contests.
