I put my 280W of solar panels in 4 locations, so that when one is shaded the other three are not. By far, the 110W one on "faux davits" in the back, is the one that kicks ass! I can hinge it toward the sun, and get 2 more hours in the morning and evening. Between all 4,I get high 50 AH or even 60 on a good day, or around 30AH if really overcast.
If using multiple panels, where one is usually shaded, it IS good to use a Shotky Diode in the + wire of each panel. There is a small loss of V from this, but IMO, not as much as the loss from the sunny panel, backfeeding into the shaded ones. (Shotky diodes are the type create the least power loss) Some argue against their use, but I have had solar on my boats since the 70s, and feel that their use is warranted with my 4 separate panels. (with or without works fine, however)
The best location for a wind
unit is on a mizzen mast! If you don't have one, a stern pole is all that is left. This is unfortunately the best place for one or two HUGE solar panels that can tilt, and in the typical living anchored lifestyle, with occasionally being at sea, the solar will produce most of its power, or > 1/2 of it, 90% of the time, where as the wind
unit will produce 5X what you can use 10 or 20% of the time, and near "0" the rest of the time. At sea is where they earn their keep!
That being the case, if you have no option than put the wind unit on a stern pole, you might as well put the solar panels on a bimini rack, and accept that one will be shaded at sea, but not necessarily the majority of time at anchor.
Solar does not like dark shadows, like from a near by wind generator
7' away. A really dark shadow over just 15% of a panel might knock it down to only 10% of its rating. If there are no DARK shadows however, a very cloudy, NO sun, but bright white sky, will still produce about 75% of its rating!
So... having one on the bimini totally shaded by the mainsail under way, but the other not, is probably better than two on the back with a relatively small, but dark wind generator shadow across both of them.
on the subject have done a disservice by showing a radar arch
, or stout davits, with BOTH solar and wind on them! It that location, it is better to have one or the other.
My cruising has been about 95% living anchored out and working on the boat
, in a beautiful tropical location, and the other 5% spent at sea getting there. I used to have a wind generator also... (for many years). When I swapped it out for my aft 110W solar panel, we had so much excess that I downsized the house batteries! Solar was so much more reliable in my type of cruising...
Don't forget to fuse the panels!
Best of luck, Mark
