6000 euros for 3 solar panels
. I am in the wrong business. Though I'm guessing the support system is 1500. Gee three 130-140 watt panels
and a charge controller would be less then 800 euros ($1000 ish) Plus labor and a fancy stainless steel
arch to mount them on and a whole lotta profit.
My original though was to use a generator
for 2 hours a day. Worked ok, But noisy and always looking for fuel
is so much nicer, No noise
or fumes and no fuel
I'm guessing your basic electric
load will be 150-175 amps per day. 50 amps for fridge, 70 amps for freezer
, 15+ amps for lighting
, 10 amps PC/TV, plus a few odds and ends. That's a really rough guess. But most boats will be 80-100 amps/day with just a fridge ( one compressor).
So your looking at ballpark 45 amps per hour of panels. That's taking into account that the rated amps and the actual amps delivered will not be the same. I've measured it at about 70-75 % delivered compared to panel listing.
Using a generator, you'll want a battery charger
rated at 100 amps to recover the load in two hours. Plus 400 amps of battery
per day. This as you can only draw down 50% of the house bank. Me I would have 800 amps of house batteries. Then you have extra power for the windlass
and microwave, etc.
OK I really really need to watch my thread drift a little....
