Solar panel/regulator

[alant]

A friend, is considering fitting a solar panel

+ this regulator


http://www.maplin.co.uk/dual-16a-so...ge regulator&gclid=co_u3nn4yqwcfcqf4qodkhzsqw


to trickle charge 2 service batteries, on a swinging mooring.

Anyone got any experience of these?

Dont really think he'd need a regulator with that.

Agree
You would be better witout the regulator, which is a simple on off type and will limit the power from an already very small panel.

Solar charger gives a max output of 1.5 watts so about 0.1 amps charging with full sunshine.

Wouldnt need the 17 amp controller at all.

Rough guidline is up to 10 watts for a typical 100 ah battery no need for controller.


It is not going to contribute much towards charging batteries probably just keep them at the same level of charge as when last used.

We have found a 10w panel deck mounted panel was good enough to get our single 100 ah battery topped up from one weekend to the next.

Longer boat use during holidays has meant we have upgraded to 30 watts and a controller to keep pace with our requirements including running a cool box to chill the beers!.

Too small to be effective, particularly with two batteries.
It won't even keep up with self discharge yet alone top up a battery which has got low.

As said it certainly wont need a regulator.

You don't say what size ( capacity) the batteries are but it may not be big enough to maintain two of any appreciable size.

Two of those panels , one for each battery, would be sensible option. Or a larger single panel and a diode splitter.

I use a 5 watt panel with a 60Ah battery and no regulator

Can't add anything more to this and the previous except to say I have two of those (one each side of the cabin - mounted inside the windows for weather protection), no regulator, and a single car battery - they keep the battery going for my very light needs all summer...

Used two of those to keep 2 batteries topped up over the winter. they work to maintain the voltage but don't expect expect a low battery to be recharged.
