A fridge uses about 35 Ah a day. Let’s say the sun is shining adequately for 6 hrs at this time of year (we are 2 months beyond longest day and 1 month before equinox) so you need about 6A, which at 12v is 72W. But you will never get 72w out of a 72w panel! 00W would cover it on a good day with lots of sunshine, but I suggest at least 200W to cater for an average day. There is no right answer, the more solar you have the more likely it will cover your needs in bad weather / shorter days / shady areas etc. It often boils down to the space available rather than the ideal number of panels. Just get as much as you can afford and have room for on the roof, remembering you will still need to walk on the roof to get to lock ladders etc. If you don’t get much, consider over-rating the controller so you can add more later if necessary. I passed a boat today with four panels which apparently provide 600w ... roof line panels and exceptionally neat wiring. They were so unobtrusive and neat, I didn't see them until we were alongside ... and even where the panels were sited they were small enough to permit someone to walk along the roof if necessary. Just to run the fridge reliably in summer months, would two such panels cover it ? Rog At last!! All you need now is a gas water heater. Maybe Tony C is clearing one out?

Don't worry about it ... you'll not be disturbed in Wales.

Hold Fire Stabby - unless you are desperate to do it asap as I currently have 3 panels I intend to replace (but can't really until November as we're on the move until then)... from memory I thought they were 195 watt each but having gone through my blog, found they are 165 adding up to 495 watts rather than the 585 I'd been assuming. As damaged the heads on the screws used to attached the brackets, my plan is to replace them with same size (higher output) models to safe a lot of hassle. If Mrs Tabby hasn't already made a claim, Mark, I would be interested in taking them off your hands (swap for a decent bottle of gin and home made pie/cake/bread, of course). Could possibly meet you to give you a hand back down Hurleston October/November .... eta - sorry, that sounds a bit like the bidding war for poor @tonyc 's new toilet ........ No one as laid any claims as of yet - I'll let you know when we get back to Manchester in November and the new ones are ordered.

We have someone on the mooring who can get industrial solar panels very cheaply, and fit them too so if you want to do a deal with Mark then go ahead.

Plenty of them up the Ashby, just to the right of Basin bridge moorings... Might need some insulated boots and cable cutters mind.

I don't get why all new houses are built with solar panels as standard, if the house is pointing the right way of course..

Family member has solar on half of the roof, summertime they pay nothing to the electric company as the panels provide more than they use, winter they still have to pay a little, but not a lot as they have banked credit though summer.

I was up in our loft, swmbo is on a tidy up - "what if we die we can't expect the kids to clear it" Let them earn their inheritance say I. To be fair it's also so there is room for solar thermal gubbins. I digress, solar gubbins was showing 5.6kwh generated that day by mid afternoon, so on a sunny day they do generate more than we use. We have 2.4kwh of pv panels.

I’m just in the process of up dating mine to 2kw of panels I’m hoping I don’t have to do much generator running in winter.

Now, we just need to convince the marina dwellers in their flash boats that 'I don't like the look of them on my nice roof' is one argument, but the many in favour of solar panels easily override this single selfish one.
