Voided warranty? I wonder under what circumstances one might need to use a warranty on a solar panel. They either work, or not.
In theory a diode in panel could fail, but this doesn't happen too often.
And of course there is a matter of aging (=decreased output), and warranty would specify N% after M years, but I have yet to see a user that measured and documented this decrease accurately, determined that his "N%" after M years was less than that promised by the warranty, and filed a claim.
Just for your information, Solar panels come with warranties for not only the panels but also the controllers amongst other things are warranted. I called the manufacture this morning and any modifications (remove the alligator clips, etc) voids the warranty.
