I have two solar panels that were going to be trashed at work. I want to use them to charge batteries on my RV but i noticed they put out around 20 volts in direct sunlight. So i am wondering:
-isn’t this way too much voltage for a 12 volt system?
-do a need some sort of a regulator connected to keep them from overcharging?
