Video (http://www.youtube.com/watch?v=a0LXEJiJES0) of the panel on my van.
I'm bored............

Mate well impressed also where did you get digital reader for batt from ...Is the solar panel mounted to roof rack do they do smaller ?
-
It is attached to the roofrack. You can get smaller than 12w but I dont think it would produce much power.
I'll look for a link to the battery reader.

thankyou ordered

You're welcom. I'm glad my obsession with recording things has a use. ;D

This is the solar panel

i like it mate very nice,quick question if you had a split relay could you just turn your engine on to power it up or has it gota actually charge up slowly?,i must do about 30 miles a day 1 and a half hour in traffic in the mornings and could be the same when i finish so i think i will be ok with the relay!

You may just be ok IMHO. You may have to stick a normal leisure battery charger on it once a week and then see how it goes. You may even have to only do it every two weeks or even less.
A leisure battery will only accept a trickle charge, it has nothing to do with the alternators charging capacity.
I have a 110 amp leisure battery in my van. The battery when about 75% charged will accept about 6 to 7 amps per hour which reduces as the battery gets 'fuller'.
If your pump draws 3.5 amps and hour and you are actually pumping water for 4 hours, then you will use 14 amps. If you spend 3 hours travelling and your battery is accepting 6 amps, then you will probably nearly fully charge your battery every day (remembering that when my battery is just about fully charged it may only be accepting 1 to 1.5 amps an hour.
Your alternator will be providing enough to charge the leisure battery whether idling in trafic or cruising on the motorway. In fact, from a charging point of view of your leisure battery, it is better to be stuck in traffic.

Thanks spuce :)

Hi Stewart,
Do you find a voltmeter gauge a useable accessory?
The reason for asking is that when I come in from work and switch off, my voltage meter across the leisure battery reads high, and takes a long time to settle down to its true voltage so at a glance initially, I don't know exactly how much charge is still left in the battery.
I have a split charge relay.
Also, the difference in voltage between a fully charged leisure battery and a 75% charged one is very small.

I like gadgets and numbers. It does give me an idea though.
I've never really understood the full/part charged stuff with batteries.
When it has been on charge it can go up to 13+ and so far is useable down to 11 without any issues.
My car batteries worked to a reading of 10.
Maybe someone can explain.
