Solar Power

Hi,

Just wondering if anyone can help me with advice on Solar Power.
I currently have a Evakool fridgemate 70L fridge which I run off a 100a/H fullriver battery which sits in a ABR Flyer.

For those longer trips I am looking at Solar power.

Can anyone recommend a good panel for this setup?

I have been looking at these two:

a. http://kampers.com.au/sale.php?p=100_Watt_Kit&gd=0

b. http://www.sidewinder.com.au/page159.html (80 watt portable special)

It seems the ABR model is Monocrystalline model which ABR states is better than Polycrystalline (or Multicrystalline). But I am not sure what the kulkyne model is.

Any suggestions on the wattage I need? I only really use the fridge, occasional inverter to charge mobiles and a small low voltage torpedo abr light.

Thanks for your help.
Ben

Just looking at this myself, we have an old 29l engel.

So how long does your battery last now until it is down to 50%?

That should give you a rough idea of how many amps you draw in a day.

Will you be stationary and not topping up the battery for a good few days at a time, or will you be running the car every 2nd day or so to top up the battery?

Do you run your fridge as a fridge or as a fridge and freezer?
Higher current draw as a freezer.

Will you place the solar panel once in a day and leave it or will you be rotating it a few times a day to get best performance?

Will you place the panel seperately to the rig in full sun, or will it be mounted on the rig and possibly get shade during the day?

Most people we come across find the 80 or 100W OK, with a bit of thought as to it's use.

Do you camp mainly in southern Oz, or do you camp in northern Oz, with higher daily temps and therefore more current draw from the fridge?

Some would say you never have enough solar panel capacity. :o)

Hi John thanks for your reply.

Battery takes about 1 day to get down to 50% I estimate.

Probably stationery most of the time not running the engine.

Run the fridge as a fridge and freezer.

Prob rotate the panel a few times a day and place in the sun as best as I can. It would not be mounted on a car or trailer.

Camp in Vic at the moment, but hoping to make it back to QLD soon.

Cheers
Ben

The Kulkyne Kampers 120W model definately looks the winner on both price and amps unless I am missing something compared to the ABR Sidewinder 100W model?

From my research if you want to run fully on solar, say if you are parked up for a week you will need 200amp hr of battery with a min of 2 x 80w solar panels. I run 1 80w with a 100amp hr battery and it will not keep up even in the best of conditions if you are on a long stay. Cheers Tony.

PS - I have an 80l WAECO, all the rest are LED Lights and occasioally a 12v fluro outdoor light. You need the two 80w panels mainly to keep up with the fridge.

I have a 60l evakool an 100AH of AGM

80W is not enough in SE qld to run indefinitely. Believe me, I tried to make it last for a 2-3 frustrating years before I bought more panels.

100-120W is more like it.

I now have 145W and that appears more than ample

Agree with the above. I run 2 x 130w mono panels with 460 amp battery bank. I never have to plug in the 240v charger.

I agree with the above, I have 2x75 watt solar panels and 2x110 amp/hr AGM's and ran two Bushman fridges(one as a freezer -15) for 10 weeks in far North Queensland, batteries never went below 75%

I originally bought two of these and made up a lead and regulator for one of my fridges, they were so good I bought another 4 and now have them fitted on my van permanently.
I even got the gov. rebate for the panels as a bonus.

Hi wazzaaaa,

Do you have a link to the particular gov. rebate that you refer to?

Ben this is the Govt. site
Govt.

But this is the crowd that buy the rec'c
http://www.greenenergytrading.com.au/

Below is a copy of my first email contact with them


Hi Wazza



Yes that is correct you can claim RECs for a system installed on caravan - however you do need to provide a residential address to calculate the RECs. Unless the panels were installed by a BCSE accredited installer you can only claim in lots of 5 years for your system.



We are currently buying RECs at $49.00 per REC until the end of next week.


It normally takes approx 5-10 days for the RECs to become registered and payment can take 3-4 days depending on the banks processing time, so please expect your payment within 2-3 working weeks of us receiving your form.



Please include a copy of your “proof of purchase” invoice with your assignment form (copy attached).



Please don’t hesitate to call or email if you have any questions. I have explained below how to calculate the amount of RECs your system is worth.



The level of RECs per PV system is dependent on the size of the system and the Solar Zone Rating of the installation. Which zone the system falls under is determined by Postcode (I have attached the solar zone postcode table for your reference).

System Capacity (kW) multiplied by x Solar Zone Rating multiplied by x Deeming Period ( 5 or 15 years)

(____________) kW x ( ______________) x (________________) years = No. of RECs (rounded down to the nearest whole number)

No. of RECs ___________ x REC Value $ ____________ = Expected Payment $ ___________



An example is: 1kw installed in Sydney (postcode 2000 falls under zone 3 and zone 3 calculation is 1.382) for a claim of 15 years is as follows: 1 x 1.382 x 15= 20.73 and rounded down that is 20 RECs . 20 recs x $41 per REC= payment of $820.00


Kind regards

Thanks for those like Wazza!

So if I was to purchase a 120W model would the system capacity be 0.12kW? Or is it multiplied by 24 hrs in a day?

Cheers,
Ben

I'm just reading this link:
http://www.environment.gov.au/settlements/renewable/pv/index.html

So if I was to buy 4 x
http://kampers.com.au/sale.php?p=120_Watt_Kit&gd=0

to make up 480W to meet the minimum size for a new system of 450W.

Panels would cost 4 x $1170 = $4680
Gov rebate is ($8/W up to 1kW)= $8 * 480W = $3840

So in total I would only pay $840 for 4 x 120W panels?

No Ben if only that good,

I have 6x 65w panels ( cost me $2190 + postage)which is .39 kw x my zone of "3" which is 1.382 x as I installed mine myself it is only "5 " every 5 years for 15 years = 2.6949 as they round down it is only two rec's @ $49 total of $98 I received for nothing. At the time I applied $46 was what they paid per rec it may be more now.
It seemed a bit complex at first but for the free $98 now and again @ 5 years and again @ 10 years it was worth it in the end.

I use a 120W solar kit (Home built) to keep the batteries topped up on the camper trailer (Water pump, Waeco CF110, CD Player, Laptop)
This is fine for 3 - 4 days in hot weather, for extended stays I have a 40amp solar regular wired up on the Hilux for a top up.

Cheers,

Jeff
