worst panel

I was considering this panel in good faith, but after reviewing it with Integrated Sun, I came to know that it is the worst panel. Then, they tried to swap the panel. I thought they should have done it initially, before attempting to make this subpar option seem sensible to me

Great panels

These panels are on the lower cost side, but they work perfectly fine! They also have a really nice look to them. I would highly recommend them!

Warranty not honored - no customer support

We had a solar panel shatter in an array installed 7 years ago. Panels are under warranty. After 6 months of back and forth there is minimal/no help from Phono. There are NO replacement panels available. What kind of manufacturer does not maintain product reserves! There is no customer support! I can’t recommend to use phonos for such a big investment. Better to use a solar panel supplier who honors their guaranteed products and provides support after purchase.

Reliable product!

I have had them for over 6 years and they have outperformed what they had promised!

They've been working well

I put the new Phono400 panels on my house and so far they have been working very well.

Zero support after the sale.

My system has 33 of the 250 watt modules currently under phono's warranty, installed by 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, Bill Shuster 760-331-9846 2090 rio vista dr., Fallbrook, Ca. 92028
