I put the new Phono400 panels on my house and so far they have been working very well.
My system has 33 of the 250 watt modules currently under phono's warranty, installed by https://www.cosmicsolar.com/.
1 module has failed.
What is the procedure to get it repaired of replaced?
PHONO USA doesn't answer phones or respond to e-mails from the installer or myself.
Thanks for your time,

We live in Virginia and have had these panels for over 5 years. The panels are reliable and perform well over long periods of time.
