When you evaluate solar panels for your project you will need to make a choice between monocrystalline and polycrystalline. Since we recommend polycrystalline let s start there. This equals thirty amp hours a day meaning you would need two one hundred watt panels to fully recharge your rv. The general rule of thumb is that a 100 watt solar panel can produce about 30 amp hours per day so you can use this guideline to determine about how many panels you need.
