Hate to say but it will not
work, your PWM charge controller only switches the panel voltage on and off, it does not lower the voltage, You need a charge controller such as some of the more expensive
MPPT charge controllers. If the Controller you have will accept the higher voltage you will not do any damage but will only get half the rated
power as your
battery will pull the module voltage down to battery voltage or 12? volts but the max
current will not change. approx 5 amps at 12.5 volts is only 62 watts. You need a different charge controller or 12 volt (16 - 18 volt)
solar panel to use with your existing controller.
