How much solar panel to charge 4 batteries in series.

If you have a 50 volt and 10 amp current coming from your solar panels but only want 15 volts the pnw charge controller will send a 15 volt 10 amp current into your battery. So you need 1200 250 4 8 hours of bright sunlight. There are other solar panels with various power ratings you can install to charge your batteries such as 100 watts 150 watts 235 watts 250 watts and many more.

Charging time 40 hours 10 of 40. You should use a charge controller to protect the equipment. Then divide the battery capacity which is 50 ah by the ampere per hour rating of the solar panel which is 1 25 amps which will be the charging time. If you connect the four 6 volt batteries in series then its like one 24 volt battery.

Then add 10 of the charging time. You generally want to have the vmp of the solar panels 10 20 higher than the battery voltage.
