Step 2 – Calculate your total weekly amps needed

Multiply total amps hours per day by the number of days per week (i.e. weekend camping: multiply total amp hours x 2 days, full-time camping: multiply total amps per day x 7 days).
_____________ amps per x ______________# of days of use per week = ________________ total amps

Step 3 – Find the perfect solar panels for your RV

Match your estimated weekly amp usage with the right RV Solar Panel Kit
