Hi all, we installed a PHONO solar system recently with excellent results. PHONO panels have it the market very hard and have long history of quality panels. We sell PHONOs as our entry level (others sell them as their top panel) but I must say they will be very quickly upping the charts past Trina. The 2kw (8 panels) installed produced 2.2kw easily and 1,5kw when overcast. If you have any recent results in PHONO panels, would live to hear about it.
