Solar Panel Disconnected from SUN
I am planning installing 4X140W panels(parallel)flat mounted going to 15A breakers(so they can be switched off if needed) to the charge. The panel have ISC of 7.50 each times 4 equal 30. The controlle...

Isc for 120w poly should be about 7.6 and for 130w its 8.2 (80w is 5.1) It is all in proportion, so 140w should be 140/130 x 8.2= 8.8
Some panel Iscs are lower than that per watt, which means of course that their panel voltages are higher. Price comparison between 12v PWM should be in dollars per amp, not dollars per watt, since it is the amps you are after not the watts.
