435W Solar Panels – Commercial Grade – Bulk Available (First Solar)
These are utility-grade panels used in large solar farms — not cheap residential roof panels.
Perfect for:
Off-grid power systems
Solar farms / expansions
RV & mobile power setups
Experimental / battery charging systems
Solar resellers & installers
Note: You can use them on a residential home roof, but they’re not compatible with typical residential microinverter setups (like Enphase). These are high-voltage commercial panels (Vmp ~184V, Voc ~219V, low current). They work best with a hybrid/off-grid inverter that supports high-voltage PV input (often run as 2 panels in series per string), or on a ground-mount rack.
Specs:
Brand: First Solar
Model: FS-6435A
Power: 435 Watts
Voltage @ MPP: 183.6V
Open Circuit Voltage: 219.6V
Current @ MPP: 2.37A

NOTE: These are high-voltage commercial modules, so you will need a compatible inverter or charge controller.

$65 per panel if you buy more than 10.
$75 per panel if you buy less than 10.
