The boat my wife and I plan to Great Loop on - has solar panels.
I don't think any of the Formula's do yet?
But, my question to those with a generator:
Are you able to tell how many kWh/gallon of diesel you get?
I've run the numbers 100 ways from Sunday on solar for my home, and in PA, where grid is cheap and sunshine is less plentiful, it's a hard sale...
But on a boat... you have no grid.
And on the loop, you're running heat/ac/internet/cooktop/etc etc etc 24/7/365.
SO... the analytical mind in me wants to know, when you run diesel through a generator, what's the gallon to kWh conversion? it's not 1:1 as no engine is 100% efficient.
I think you're looking at 40% at best...
1 gallon is about $5 on the water, so that's 37.95 kWh* 40% = 15.18 kWh
/ $5 = $1 = 3.036 kWh
1 kWh = $0.33
at $0.33 kWh, and with 'limited' filling stations, not to mention smoke, CO, noise, vibration, etc. Solar + battery starts to make some appealing arguments.
Anyway, just thinking out loud, and wondering what people see out of real world marine generators. thanks!

Diesel Generator vs. Gas Generator: Which is More Efficient?
If you're considering a commercial backup generator for your business, you'll have a lot of decisions to make. One of the first things to consider is the fuel source. One common question is, are diesel generators better than gas? The answer is, it depends on the needs of your business. To...
