 The reason for this is related to how lead-acid banks charge; ​ they can take a ton of current in the first ~80% of charging (Bulk) then they hit a kind of wall.  At that point you could drive 100mph or hook the bank up to the Hoover Dam's electrical output and it wouldn'​t finish charging significantly faster. The reason for this is related to how lead-acid banks charge; ​ they can take a ton of current in the first ~80% of charging (Bulk) then they hit a kind of wall.  At that point you could drive 100mph or hook the bank up to the Hoover Dam's electrical output and it wouldn'​t finish charging significantly faster.
  
-From ~80% to 100% (Absorption stage) charging requires little current but a long time holding at a relatively high voltage. ​ So in our alt+solar scenario the alternator does the heavy lifting in first bit and then a small solar install does the light (but lengthy) work at the end.+From ~80% to 100% (Absorption stage) charging requires little current but a long time holding at a relatively high voltage. ​ So in our alt+solar scenario the alternator does the heavy lifting in the beginning ​then a small solar install does the light (but lengthy) work at the end.((The solar will also contribute during Bulk when the sun is shining.))
