Im going to start building some panels and store it in 12vdc deep cycle batteries. I have been reading much about the charging part. could I use 16 volts instead of the norm 18 volts and still charge batteries?I know if you have to run a long distance you need voltage,I also know about hooking cells up in series and par. I was just wondering about making the panel with 16vdc instead of 18.tks.
