Second. Depending on how "big" your marine battery is that 90 watt panel may not be big enough to charge by itself. What is the AH rating of your marine battery? A good ratio of battery charging is C/8 to C/12 where C = the Ah of the battery. So a 200Ah battery will be 200/8 = 25 amps and 200/12 = 17 amps.
