New Kyocera 250W SP Installation

[konakoma]

Plan to install 1-250W Fixed Frame solar panel on top of our yacht's davits with the prefabricated kit, and wondering what would be the best controller. Their worksheet tells me it should keep the bank up with 8 hour daily use of sailing instruments and autopilot, 24 hours of fridge/freezer combo and misc low draw stuff,
Have 4 x 232 ah Interstate deep cycle flooded batteries wired in 2 banks, charged thru a Truecharge 60 with a combiner. Would like to know how much power is being generated day to day too. Anybody with similar and words of wisdom would be much appreciated for this newby to solar. We also have a Northern Lights 6500 KW genset for cloudy, stormy times. Thanks.

Hi Tom,
Depending on sun time, angle of sun to panels and mast shading affect, I would expect your real world daily power output from a 250W panel will be 75 to 100AH per day.
That is about the average I have been getting now for 7 years from my 260W of solar. Which is by the way, the reason I just added 170W and have plans to add another 480W.
