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 :)

Will these Coleman solar panels work with a 6 volt system in my RV?

To answer correctly, I would need to know what you mean by a "6 volt system". RVs commonly use 12 volt electrical systems, but sometimes an RV will have two 6 volt batteries connected in series to produce 12 volts (nominal). If this is your setup, then, yes, you can charge two 6 volt batteries at once, just be sure to connect the charge controller to each end of the series, DO NOT connect to each 6 volt battery individually, because most controllers are designed to charge 12 volt (nominal) batteries or battery systems (i.e. two 6 volt batteries in series is OK).
On the other hand, if you truly have a 6 volt system, i.e an RV that runs from a single 6 volt battery, then you must not try to use a 12 volt charge controller and 12 volt-rated panel.

The Coleman 40W Folding solar panel is the ideal choice for charging any 12 volt battery. This product is not designed to charge a 6 volt battery system.

The better approach is to connect the two panels in parallel, and then to the controller, assuming that the controller you select is rated for the total amperage of the two panels. There is a good chance that the controller that you have for your 100 watt panel can handle the additional 40 watts... just check the controller's rated amperage (volts * amps approximately equals watts). Note that I said "in parallel", i.e. connect the positive wires of each panel together and the negative wires together, then connect these joined leads to the appropriate connector on the controller. This will give you exactly the same effect as having a single 140 watt panel, and will supply the correct voltage to the controller. Using separate controllers on each panel is not necessary unless the controller cannot handle the combined amperage, and in fact needlessly complicates the system. I run parallel-connected panels through a single controller myself, and it works well.

We would advise separating the two panels and placing both through their own controllers onto your batteries.

The Coleman 40W Folding Solar Panel is designed with crystalline solar cell technology, this does require direct (or at least for periods of the day direct) sun to charge a 12V battery.

You can purchase Y connectors that will allow you to combine multiple panels. You can find them online. You simply plug them into the connector. Just make sure that the charge controller can handle the combined amps of the panels.

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.

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.

Which type of 12 V Batteries should I purchase for these panels?

I purchased 3 of these panels to set up and run in parallel. I am planning to purchase 3 - 12 V Batteries just for these panels. But there are so many different variations & types of 12 V batteries. Can you recommend what would be the best battery.
