I have received another fee quote for labour only
Install Roof Top Solar Panels x 4, Wire panels to Combiner box thru RV Roof & Seal
Wire to Controller
Wire to Meter
Wire to Safety switches & Batteries, Anchor system & Test
INVERTER: Install Inverter, Shunt, Monitor & Temp Sensor, Chase Wires & Test
Remove 12v Battery(s) & Install 300Ah Lithium battery, Set up BMS system
This looks better than the first quote I received. Still based on your feedback, probably this is a high side of the pricing (unless they charge $200 / hour).
