(upbeat music)  - Hi, I'm Jeff Cote with Pacific Yacht Systems.  And what we're going to be talking about next is  now that you've made a decision about doing solar,  how much solar do you need on your boat?  Around here in the Pacific Northwest,  we're pretty lucky in the summer months,  the formula or the conversion of figuring out  how many amp hours you're gonna to get from a solar panel  of so many Watts is effectively a factor of four.  So between, I would say late May to middle of September,  you're looking at, if you've got a a hundred watt panel,  you're going to be getting a daily output  on average of about 25 amp hours a day.  So if let's go backwards and if you say  your daily amp hours consumption on your boat  and you've got a mid sized boat,  maybe a 35 40 foot sailboat,  or even a small power boat 35 footish,  you're basically looking at about 100 amp hours a day  of power consumption on that boat with refrigeration.  So your solar array would need to offset everything  would be about 400 Watts.  But that's one end of the spectrum.  Some boaters don't come to us and say,  I want solar to do everything for me,  they say, I want to extend my airtime at anchor  by another day or by another two days.  And so that's where most of the solar arrays  that we end up basically installing  or selling to boaters is probably around 200 to 300 Watts.  And it's not enough to do everything on their boat,  but it's enough to give them more time and anchor.  And it's a good way to offset having to buy more batteries  and it allows them to recharge their batteries  and enjoy their time on the water in the summer.  If you've wanted to have, or have more questions about  solar panels, see our other videos and thanks for watching.
