hi current needed

most new er cars need
minimum of 10 to 20 amps to run the engine and DRL with out much else

at full loads with AC and wipers and high beams most cars are approaching
100 amps
and many of the big SUVs are considerably over that

which is why the ECM has control of charge rate ... so it can minimize alternator load on the engine when not needed

you have chosen a pathway that will present a considerable challenge

fresnel lenses can produce upwards of 2000f at the focal point .... that would be dependent on the sun and its relative position to the TEG and lens ... which would be in constant flux in a car
