BUYER BEWARE: Still on SOLAR WATTAGE alterations by local unscrupulous PV solar panel Vendors,this is how you DETECT Fake wattage labels .
As you can see from the fake label,its indicated 600w,thats first red flag. actually This solar panel is 140W (Most Solar Panels here in kenya has Max of 415w)
SO How do you know its 140W? This is how you calculate.
Label 1: Multiply Current by Voltage( I × V = Watts)
Current at Max Power 7.54A
Voltage at Max Power 18.6V
WATTS = 7.54A × 18.6V = 140.244W
Label 2:
Current at Max Power 5.56A
Voltage at Max Power 18V
5.56A× 18V = 100.08W.
NB: ALL SOLAR PANELS HAVE SILVER STICKERS,Anything else is FAKE: NOW YOU KNOW. Be informed always.
FYI : THERE IS NO FAKE PV SOLAR PANEL,CHINA IS THE LEADING Manufacturer of PV Solar Panels,so dont pay attention to Name or origin because anyone can go to china and order names to labelled on the panels,even Big brands get them from China and have their names on it.
