ONE (1) SUNPOWER 435W E20-435-COM US MADE 85.6 VOLT COMMERCIAL SOLAR PANEL. I HAVE A FEW EXTRA I'M NOT USING. $349 EACH. EACH PANEL IS ABOUT 42" WIDE AND 82" LONG AND WEIGHS ABOUT 56 POUNDS.
CHECK THOSE CHEAP PER WATT PANELS YOU ARE CONSIDERING AND YOU'LL NOTICE HOW LOW THE VOLTAGE IS. YOU'LL BE TAKING UP A LOT OF SPACE WITH LOW VOLTAGE. YOU'LL NEED 2.5 X THE NUMBER OF PANELS.
While technically possible, installing solar panels with high wattage but low voltage is generally not recommended as it can lead to inefficiencies in your system due to higher current draw, requiring thicker wiring and potentially stressing your charge controller, making it less optimal for maximizing energy production compared to using panels with a higher voltage for their wattage output.
Higher voltage solar panels offer multiple benefits that enhance the efficiency of solar energy systems
I ALSO HAVE SOME ENPHASE IQ8A MICRO INVERTERS AT $199 EACH
