    @tissuekitte 13 …
    @tissuekitte 13 dollars a year but due to 10 percent increase in electric per year pay back is in 11 to 12 years, do the math, i did. Just now because. THATS AT 8 hours of sunshine a day . not everyday is a good sunny day.

    so, only $250 to power two light bulbs? great investment. it pays for itself in only 50 years. of course, it will only last 30 years before they no longer work…..

    I have the same …
    I have the same solar kit as Dan, but mine just shows a maximum no load voltage of 14 volts on the regulator even with all three panels plugged in under full sunlight. When I test the panel voltage with a multemeter they show 22 volts each. On this video the voltmeter shows 22 volts when all the loads are unplugged. Is the regulator broken or am I being missing something? Any ideas?

    lol…i saw this video and i went to get my solar panels at harbor freight here in orange county california….i also got a 12 volt deep cycle marine battery and a 750 pure sine inverter….i was charging my lap top my flashlight and my cell phone….i love it….i’m actually considering getting my batteries and several more panels…in the future…thanks dan for the educational info..

    I had an idea a few days ago, do you know how to turn 4volts into a higher voltage around 10v?

    In a system with AC …
    In a system with AC and DC loads a higher voltage means the inverter doesn’t have to work as hard to do the conversion as it would with a lower voltage. This makes it easier to start difficult loads like motors, as less current is going through the inverter components.

    That said in a smaller system you’re probably not as likely to run that stuff from the inverter, so that’s probably not a bad rule of thumb to keep things simple.

    You need to measure …
    You need to measure short circuit current on the panels. Check with specifications. That way you can find out if it’s the panels. If the panels are fine, move on to next possibility: cables, then controller, then batteries. If your batteris are dead no current will be pulled from the panels to charge them. Just go through one by one.

    Maybe, but I’m a 4th year Renewable Energy Engineer at UNSW, and thats what I learnt in my “Stand alone PV” class. Less than 1 kW, 12V is recommended.

    Actually, I would say that if you’re less than 1 KW and not planning on running DC loads (and instead running AC loads via an inverter) it’s not a bad idea to try to go with a higher voltage.

    why would you plug in bulbs when you have the sun and without the sun you still have no light to power the bulbs

    ok lets start with this: under 1 kW solar panels installed, use 12 V, 1-2 kW use 24 V, then use 48 V etc. So I assume you have lass than a kW instaled, so use 12 battery: that means parallel. However, pick your batteries so you don’t have more than 3 in parallel, you will get uneven charging problems (hence why you should then connect batteries in series for larger systems). I suspect if your batteries and panels are ok, your inverter is the culprit.

    Greetings, What …
    Greetings, What angle are your panels mounted? At your QTH, at solar noon, the sun’s at 26 degrees on 12-20, 75 degrees on 6-20, and 51 degrees on the equinoxes. Without the ’sun tracker’, they’ll only put out maximum at noon and when perpendicular to the sun. As I understand, the output drops off fairly rapidly as the light angle increases. 10 ga wire should be sufficient at about 0.06 ohms for 60 feet. Best I can offer.

    I have four sets of three parallel panels. These are the same ones that Dan is showing here. I tried like you said to put some in series and some in parallel Actually I put three sets in series and come up with an open voltage of 50 volts. This is on a cloudy day and hooked it to the controller. Zip nothing. I went back to parallel and there was about 1/4 amp. I am just about ready to buy three good 200 watt panels and do it right.

    I think its 15 degree not 45 degree, well just get maximum sun light.
    what is the total voltage from the panel, also the Amp and watts to get high Amp connect some panel in series and some in parrale. in parrale the amp stays the same but in series the amp doubles. eg 36 or 40 pieces of panels gives about 30watt , 3.5 Amp about 18volt

    All paralleled …
    All paralleled panels are showing a voltage of 18 to 20 volts. I have tested each panel individually and each one puts out about 18 to 20 volts in direct sun. I have used other amp meters to the batteries from the charge controller and the same story. The panels are oriented to the south at about a 45 degree angle. Any other ideas. I can send you a youtube and show you what I have and how everything is hooked up if you like.
