What do people do with their solar setups when their not camping?

Hi all,

I have a small solar system that I use for camping consisting of:

80 Watt solar panel
Basic Steca regulator (Solsum 8.8F PWM)
100 A/H AGM Battery
400W modified sine wave inverter

Find it works great running a 40L Waeco, lights and a few other mod cons for those times im lucky enough to be out camping.

When im not camping though, I rest the panel against a sunny part of the back fence run 20 metres of $1 a metre wire from Dick Smith into the house and charge three dodgy 24 a/h batteries I was given a while back. From this I run my waeco as a beer fridge 24/7, charge AA/AAA batteries, surf the net on my laptop etc etc. Every now and then I connect my 100 a/h good battery just to keep it in tip top condition. I have been doing this for nearly a year now and find that the batteries get plenty of charge, I use the laptop as much as I like and feel good about not using the grid to keep my beers ice cold!

Seems like a waste to have a perfectly good renewable energy system lying around doing nothing so I am curious as to what other people use their systems for when at home? So whose first?

Cheers

Hi,
I leave my solar system on the roof 24/7 and turn the fridge on only every now an then, as vehicle sits in a carport for up to a week at a time unused.

Last month only used $42 of diesel, so it does not get driven much as I can walk to shops (when desperate for exercise)

When I do take it out I leave the Cranking battery also connected to Aux battery system so all 3 are charged by solar system and runs fridge simultaneously just to keep everything charged and operational.

Its good to see its keeping everything ready for the next outing, rather than running a mains powered battery charger to keep the batteries topped up.

Our 80 w panel is mounted on the roof of the tow vehicle and keeps the camping battery charged (even though it is often garaged). Engel is ready to use as fridge or freezer when shopping.

Meanwhile i have been thinking i should harness the power from the four panels on the caravan - could probably power half a house.

very good idea, you may actually make some differance to the ole "greenhouse" effect...............
well done and a credit to you
I am curious, does a solar panel last longer if NOT used and covered from the sun or does it help it by being used like a battery ?????

The two 64 watt panels sit on the garage roof with the lead connected up to the camper trailer batteries and every once and a while I connect them to several other batteries.
I have two in the tinny one on the outboard and one on an electric motor and two batteries in those black boxes that are used around the camp site or on a canoe.
All of my batteries have Anderson type plugs connected ready to take a free charge.
I have also lined my garden beds in the back yard with 12 volt downlights (pointing up) and the pergola (pointing down) that I will turn on for mood type lighting really looks nice providing the lawns are mowed and the kids toys aren't scattered around :-)

Keeps the Karavan charged up and the fridge cool while in the shed. Many don't realise how they should keep the systems charged up. Cycles up every day to 100% and drops the charge marginally overnight without the sunlight.

I was a little worried about using my 'good' camping battery while not camping, just didnt want to use any of its "cycles" up!

If I could just expand the scope of this thread a little.

We have often talked about mounting solar panels on the roof of the 4WD for accessories and the fridge. Its a 100 series. But the question of damage from unknown sources arises. I would accept large hailstones but anything else is an unknown.

I would appreciate anyone's comments.
