Hi, after reading all infos here and checking most datas found in the net plus talking to a local installer i confused and i need your help.
I have a monohull
with limited space and i could use only my arch which is 1.6 m wide for the solar
panel. Ofcorse a radar
and air x is already installed which might give some shade but i am willing to scrap the air x although i just bought the spreco blades.
Question: i like the new sunpower 345 panel which comes arround 800 Dollar here in europe
but it looks like i can only use a expensive Mppt
controller who can handle th max 70 C from the panel / Tristar or outback. So it will costs me another 700 usd so all in will reach 1800 usd for a one panel installation
Compared with a simple 140 w / controller setup which i could have for 3-400 usd it is a tough decision.
Any advice ? My batteries are 2 x 6 V Trojan 435 AH AND i have no fridge sofar, 30 AH at anchor
, 80 AH sailing i need .
I am in Portugal
and will visit the sunny Med next year
