What solar panels, and what charge controller do I need?

Gel Cell Batteries will only take 13.9 Volts MAX!....and charge with low amps. I sell Batteries at my Marina/RV Park. Authorized Dealer for most major brands, since 1982. We cut open a Gel Cell after 6 months at 14.4 volts. The Gell was like tough rubber. Toast. With that amount of Solar, you may have a fire issue with Gells.
