Solar panels

[snootie]

A friend has asked me to source solar panels for him (he is not in the US/ the boat is currently in Florida. He is purchasing a 95’ Broward. He intends to put 24 solar panels on the cabin top (each panel 400-450w). I am mostly seeing panels of approximately 100w. Does anyone have any suggestions that will fit his request and/or if this is the correct wattage for his boat?

400-450W is the realm of commercial systems more than boating systems, so you’ll need to find a good commercial solar provider. There are many online. The cream of that crop is probably the Sunpower 435W commercial panel. Those can be hard to come by. Next up in quality are probably the Panasonic HIT and LG NeON panels, although I think the largest for both of those is in the high 3xxW/panel.

No way to answer if the quantity proposed is right without a whole lot more information. A 20kW array on a boat would certainly be interesting, but at 95’ you might be able to fit it.

I have four 435 watt sunpowers solar panels. They put out a lot of power occasionally you can find these in group lots on ebay

I’ve got 50 - 315 watt 36 volt commercial panels refurbished for marine use, if interested PM me.

These panels sizes are readily available for about $1,600ea.

I think your buddy will have to build another roof over that Broward 95 to fit about 560sq. ft of panels.

No one can tell you the correct wattage without knowing the power demand.

I kinda think your question may be a joke.

The energysage price of $4/W is the installed price. The panels themselves should be about $1/W for most decent grades up to a premium of $1.5-2/W for the boutique brands.

The average installed price of the panel on a per-Watt basis. Installed price includes not just the panel, but additional equipment (like inverters), installation and permitting costs. Prices in $/W let you compare across solar equipment similar to comparing $/sqft for houses of different sizes.
