I've been trying to work out how much Solar and batteries I need, ideally to be able to use the panels for most electricity even through winter. I have lots of roof space and I budgeted for a lot of Solar so I'm ok with the finance side.
I have done the usage calcs based on 'worst case' or maximum potential use, and overspeced the solar needs by 100% to account for winter. However, the Bimble solar calc seems to suggest I need a 1166 AH battery bank!? I assume this is because I need double the AH I use so as not to run the batteries to 0. That's a lot of batteries though! Am I understanding this correctly?
What do other potentially power hungry users have?

Just thinking about how best to bring my solar cabling into the boat - I've seen it going into mushroom vents but I'm doubtful I'll be able to run it inside the roof space without taking half the ceiling down - it's a few metres. So I looked for waterproof junction boxes and found some for solar panels - with diodes already inside. That set me a thinking regarding blocking diodes and whether I need them!
So, before I order the cheapest little plastic box with a grommeted hole, perhaps I could ask what others have used and whether diodes are necessary!
Hey so I have recently got myself a boat which is a norman 27 fibreglass boat. I am currently pondering how I am going to install solar panels onto this boat, I have heard that the best way is to drill them on but I dont really want to do that as I have heard fibreglass is fragile.
These panels are big (1.6M X 1M) so the only 2 places for them are the front cabin roof and the back cabin roof.
So is there any alternative way to get the panels onto the boat roof, I was thinking maybe there is some super strong industrial glue or even some sort of metal wire rope that anchors it at 4 points.
I have no clue how I am going to do this so open to any suggestions.
Here is the panels I have bought: http://www.ebay.co.uk/itm/282164412810 2X 250w
