here's an example : http://www.jaharrison.me.uk/Misc/Solar/index.html it also shows the average daily power per season and you can see why the figures are as they are. one thing he doesn't account for is any surplus in the summer would flatten the curve (basically the opposite to what you experience ) though maybe he has a way to harvest the surplus ( selling to Powergen for instance )

In a city a car can either follow me because I will be in the centre of the lane or overtake if (as) safe to do so (as overtaking a car). If cycle lanes are provided I will use those, otherwise I am the equal of a car.

If you use power in the winter from engine or generator or shore power you will, whilst charging, suppress the output of your solar. The physics suggests the amount of energy available from sunlight in the UK is 10:1 summer:winter so the other things being equal, i.e. your batteries are in need of bulk charge, you'll get 10% (though not at any one moment so measuring amps won't be the way to tell)

thanks. A little pricey but do like the idea of user programmable voltages.

I'd be interested in a link to this 20A charger that can be manually set to 14.8V absorption.

how quaintly old-fashioned. I would require the money placed electronically into my account.

Because every who drives a car, a train or even just walks knows much better than you do how to ride your bike.

yes, you did http://www.brake.org.uk/events/15-facts-a-resources/facts/487-driver-stress other links are available

it'll be fine, should have rescued it last night though

'selfish cow', 'arsehole', 'wally' hmm. If I can't cycle down a road on which I'm legally entitled to be, with high-viz and lights without having someone like you driving angrily and putting my life in danger then yes, I'm going to disagree with you ( as well as the way you say it).

I can only admire the way you combine both.

it's bloody obvious man. Petrolhead through and through.

I have the older MagSafe adaptor and a Kensington 12V power supply. incidentally I have swapped my hard drive for an SSD and I'm sure (though not scientifically) it uses more power.

I agree with all of this and also find his 'reckless cow' comment sexist and offensive. I imagine Gazza as a motorist driving a fair bit faster than the speed limit passing far too close to cyclists in the grounds that 'they shouldn't be there anyway'.

If your assertion is true, it seems a little odd that 1. the cyclist wasn't using it and 2. the motorist didn't use its presence as a mitigating circumstance.

Or is it a case of Chinese whispers? This. Basic measurement and physics says solar is 1:10 winter to summer so 4-5W plays 60W is about right. A basic understanding of the way the sun works in the seasons also shows that doubling an array will make a much smaller difference in the number of 'self-sufficient' days that people think. I think early March to late september is easily achievable without wasting too much power in the summer. Experience shows 250W is good for a boat without fridge, 500W will do a fridge and a couple of laptops and a fridge, 1000W is for those who want to use household appliances on a large inverter.

There's absolutely no reason why you can't use all three computers on your boat. You simply need to be economical, if you're not using it shut it down, it's not often to need to run more than one.. The iMac will use the most power so only use it for mission critical stuff, the MacBook Air is the optimum for just messing about but the MacPro can be powered all day every day on a typical modern boat electrical system. I have MacBook Pro, MacBook Air and a 24" display. 8 months of the year runs off a 250W solar panel.
