200W SOLAR should be about 100 NOT $500 old style panels now
50 cent a watt is current low end price plus mounts plus wiring ect
sorry but NO none of the Lipo batterys are a true drop in YET
FOR ONE THING THEY CAN DISCHARGE FAST PUSHING ALOT OF AMPS WHERE YOU DO NOT WANT THEM
THEY REQUIRE CONTROLLERS TO LIMIT total charge
over charged Li batterys die dead
they require matched cells that then require balancing /charged to the same rate volts
buying cells and putting together a battery is not eazy
sure it can be done BUT you need to know what you are doing
systems are also complex and expensive
