Attention all marine enthusiasts!! You know you love the water. You know you hate a dead battery. Warm drinks out on the bay spoils the fun. Use this handy calculator to estimate how much solar power you need to stay charged out on the water until the wee hours of the day are over.
The Amps listed below are estimates for typical electronic gear and appliances. You may alter the amp number to suit your actual appliances and equipment. Then, enter the number of hours, or fraction thereof as a decimal, that you estimate using those items during a typical day out on the water. Scroll down to "calculate" your estimated solar panel watt requirements.
The default below is set to 5 hours of direct peak sunlight per day, and you may also edit this data field as needed. You may get more or less direct sunlight, depending on your geographic location.
