Questions & Answers for Coleman Coleman 40W Folding Solar Panel

Question

Could you please double-check the claimed amperage output? 40 watts at 12 volts should be 3.33 Amps, but it claims only 2.3 Amps maximum. Thank you.

12Volts x 3.333Amps = 40 Watts

To charge a 12 volt battery you need to increase the voltage. A normal battery charger will charge at least 14V or more. I had a 480W (6 x 80Watt) solar array. The voltage output was 17-18Volts depending if the batteries were low. Therefore 40W / 2.3A= 17.4 V This is good too charge your batteries. A deep cycle battery is charged at 12.6V

These panels are rated higher than 12 volts at max power, closer to 17 or 18 volts which would explain the amps.

answer 3
Well actually, the true open circuit voltage is at around 18 volts, which bring the amps down at 2.3 amps.

answer 4
Double check your knowledge of charging systems ;-) ... you would be looking at approx 14.8 volts when charging ~35 watts. The open circuit voltage would easily be around 18 volts ~ 41 watts.

the manufacturer has rated it for 40 watts :)

Solar panels can be wired in series or in parallel to increase voltage or amperage
respectively, and they can be wired both in series and in parallel to increase both
volts and amps.

Of course you can :)

But you would need a charge controller rated accordingly, not the one supplied with the unit.

alternatively you could have 2 'systems' power your battery bank.

Problem isnt the amperage at that point, but the wattage. 3 x 40w panels at max output would be 120w, the included controller is rated for 105w MAX.

We would advise against using a 7 amp controller with 3x 40 watt panels. Any surge or peak output will put more amps into the controller than it is rated for. We would use a 30A controller for this set-up.

Question

Does anyone have suggestions as to why this unit is not charging my MotoMaster Eliminator 800A Powerbox?

The Powerbox recharges just fine with its own AC charger but will not take a charge when hooked up to the solar panel using the connector provided.

The panel has been placed in full sun and the indicator light shows that it is providing current.

On my 800 amp booster (Nautilus), i have to turn a switch on to use DC and to charge as well. Maybe you have an on off switch too.

Yes, you can use the battery at the same time. I did this all day today, panel to controller to 12v battery, boondocking with my travel trailer.

I purchased 2 panels. I would like to connect them in parallel to get 80W. I created a Y adapter using the supplied plugs.

I connected + to + and - to -

Using the cigarette lighter adapter it doesn't work. The charging light doesnt illuminate. I've tried with one controller and and two,same result. Please advise how to connect two of these panels in parallel?
Thanks...

think looking over your set-up you have reversed polarity somewhere in your splicing. I advise purchasing the Solar 8-1 solar hub from your local Canadian Tire store. This handy connection hub will parallel up to 8 panels. Failing this you can check your polarities with a voltage meter and re-splice your panels yourself.

Hello,

Connect the two (+) wires and the two (-) wires together then connect them to the charge controller.

It will give you the same voltage but twice the wattage.

This solar panel is essentially a 12V battery charger, it cannot be used to power items such as light bulbs directly. If the panel is used in conjunction with a battery and inverter, then your lights will work.

you can but they'll have to be 12 volt lights that run off a battery- you use the panels to charge the battery during the day

how does 2.3 amps at 12 volts=40 watts-p=ie,fuzzy math

answer 1
You are correct, 2.3 amps at 12 volts does not equal 40watts.
From a practical perspective you can expect to get about 25 to 30 watts from this panel. For example, you could expect somewhere around 2.3 amps at 13 working volts, which yields 30 watts of practical output.
This is not a fault with the panel and you will find similar results with other panels (ie. a reduction from the stated theoretical power output).

In order to have an effective charge, the solar panel operates at 17.1V. 40W / 17.1V = 2.3 Amps.

The panel itself does not fold, like some others you see comprised of two or more sections.
The "folding" part of this is the stand used to angle it toward better light.
