This panel produces ~22 volts. My purpose is to operate my RV during the day and then use battery at night.

This is a typical panel designed to charge a 12v battery. This means realistically that the voltage will be tied to the voltage of the battery. As the voltage in the battery increases ( due to charging ), so will the voltage produced by the panel. You need to have a charge controller between the panel and your battery, or you will damage your battery. This will disconnect the panel once your battery is fully charged. Typically, charge controllers will also limit the voltage to around 14.4 volts or so. Cars actually run at 13.8v, not 12v.

I am not sure what kind of answer you are looking for. But as a guess, you are unsure about the open circuit voltage. With no load on the panel it will put out the maximum designed voltage, but when loaded, the voltage will drop. Maximum efficiency with this panel is around 17 volts. You can still charge a battery with direct connection to the battery, but be aware that if the battery is near full charge that there is a possibility of over charging. With this in mind it is advisable to have some sort of solar charge controller between the panel and the battery. The solar charge controller should be designed to adjust the power consumption from the panel to maximize solar panel efficiency as well as monitoring the battery charge state. Using the panel alone will work, but there is no guarantee as to battery charge status or battery health verses time.

They produce .5 volts each and you will string 36 cells together for an 18 volt panel which is used to charge 12 volt batteries. This should give you a 65 watt panel. Use sylgard 184 to encapsulate

Youre going to need deep cycle batteries as far as output it depends on how manyamp hours the batteries have the solar panel should always charge of 400 watts if tHeres sun look online how to calculate Amp hrs depending on what ur running I can run some fans lights a tv and a fridge in my rv with two batt

this is a small solar panel, it will keep a 12volt car battery charged, I use mine for a 12 volt winch for a boat hoist. you could get a inverter to connect to the battery for 110volt lights.

Yes , these are 12V panels .Under full sun , one panel can produce Around 17VDC .You will need a good solar controller to keep voltage to 12V to your batteries

Output is 110V. I installed it in my RV primarily for use when we're on the road. Saves me a lot of gas by not running the generator.

Jaco, I have used that same breaker on my RV solar panel array. I have not had any problems with it. It is well build and it is resettable should it trip. Your load I am assuming is connected directly of the batteries. You did not state how many batteries you have. Should the load be greater then 50 Amps the breaker will trip. As you have stated that your controller output is 30 Amps you should be fine.

It puts out around 13 volts, if you had a device that can convert the output to 24v maybe that would be a possibility but I don't know

Error on my earlier reply. This operates on 110 volts; does an outstanding job. Well worth the money.

The cells are supposed to put out .5volts per cell. Although on a bright sunny day they are pushing closer to .6 volts. I took my almost finished panel today. It was very cloudy outside. I have 4 columns of six cells each. The panel was putting out 14.3 volts @ 1.9 amps. I tested in on a late sunny afternoon with only 3 rows in place. It was putting out around 16v and a little over 5 amps. Hope that helps.

I think that the voltage is about 15 volts. I leave mine charging my RV battery andhave no problem with it. It stays charging for months at a time.

I'm not sure how it operates but it does not allow the battery to be overcharged. With a 30 watt solar panel my batteries stay around 13 volts in the daytime in storage. I haven't paid attention but I think the green light stays on.

I purchased this system to act as a 'test bed' prior to buying my main dual-axis 2 panel system (Two 250W, 24V 8A panels). It's a monocrystilline 100w panel stated to output 5 amps, 12volts. I see consistent 13~14 volts at 4 amps, and have hit 5 amps on really good days (but 4A are more realistic). As a test item, I had it charging a 73AH Deep Cycle Gel battery from West Marine (the panel came with a 30A PWM charge controller). It worked fine and charged the battery in a matter of short hours ( I have both an amp meter and a volt meter connected to track its output). Previously, I was using two 45W amorphous panels (Harbor Freight) that took up to 4 days to do what this one panel can do in 4 hours. Buy with confidence.

The panel does not output 5W like the specs and other reviewers suggest. The integrated *battery pack* outputs 5W, but the panel itself seems to only output in the range of 1W to 1.5W. From the specs directly from the manufacturer, the battery is 2200mah, and it takes the panel 10 hours to charge it. If you work the math out, that means it charges 220mah per hour, which would be 220ma of current @ around 5V (maybe slightly higher?), 5v * .22a = 1.1W Just because the unit has the capability to output at 5W, doesn't mean it can collect power from the sun comparable to a 5W panel.

Yes, however at 15W it won't charge fast enough to use the inverter each day. I use this panel to maintain the house batteries in between outings.
2179119
Very. It is just a smaller version of other well built solar panels. It charges well and gives about 21v without load.

yes the voltage output will vary with the amount of sunlight. I have my panels setup to produce a max of 36 vdc charging a 12 vdc battery bank. your charge controller needs to match your projected final system capacity, if there is a possibility of adding on later. I have a mix of 144s and 88s
