Howdy, I am a novice solar junkie, I moved in to a house that has 4×100 watt panels, the panels are on a ground mount over 45 ft away from the solar charger, they had the system under wired with 10 awg and the charge controler had burnt out, I got a new pwm controller 40 amp and ran 8 awg. Realizing later that this is also under rated for the length, I have since disconnected the system until I can set it up correct, the panels say they produce 5.75 or 23 amps in parallel. Before I disconnected the system it would only charge at 15.4 amps. If I move the system closer to the house I lose 4 hours of sunlight, I can not afford to get larger wires, The question, if I did my calculations right I can run 15 ft of 8awg to get full charging amps, there is no good spot to place it in the sun, if I go 20ft I get a 5% loss but have decent sun, can I go 15ft of 8awg, then splice 5 ft of 12awg and get less loss?
