I know you evolutionary types believe in invisible nonsense like the big bang and secret dark matter and you think that plants get secret energy from invisible sun beams, but quite frankly your nonsense has no merit and does no good.
Plants need food. You got to water it, make sure you planet them in rich soil. Sure a little sun is good for them but its pretty dumb to think that the plant can eat sunlight, especially when you are trying to use that as your argument why somehow we should fund dangerous solar panels.
I built solar panels for my home…it’s cheap and easy now
thanks its really helping me sir.
Tons of great free info. How do you guys make money?
not to be efencive but this is trash. ther are soler panels that you can make and you will get 100w and the soler panel can be just about the same size. and t can be cheper even with the charge controler.
you did not connect the betteries or and the inverter properly, ie in series and in parallel. one increases the voltage while the other increases the ampe.
Hi; All of my batteries are parallel and all of the solar panels are parallel. Simply all the 15 watt panels are parallel to the Xantrat C-35 charge controller that is charging all of the 12 volt batteries in parallel that are hooked to the inverter. If you suspect this is wrong where did I make my mistake. Thanks and I look forward to your input.
Series wiring refers to connecting the positive terminal of one panel to the negative terminal of another. The resulting outer positive and negative terminals will produce voltage the sum of the two panels, but the amperage stays the same as one panel. So two 12 volt/3.5 amp panels wired in parallel would produce 12 volts at 7 amps. Four panels would produce 12 volts at 14 amps.
Yes I know, everything is wired correctly. Still the best I can get is 2 amps with all 12 panels wired parallel. I use a #10 gauge wire from the roof to the charge controller. A distance of about 30 ft. Unless my amp meter is not telling me the truth I can find no reason for the low charge. I do however have a wind turbine on the system that appears to be working just fine. It is my saving grace. Any other ideas? Thanks for replying.
what is the total voltage of the panels. and what angle is the panels to the sun light? maybe some of your panel are bad or your amp guage is faulty.
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.
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
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.
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.

what about useing a batter saver i use it on my boat and double my useage out of my battery and bass pro sells them for around $40
quit toying aorund do whole ssytem
2000 wat setup of the grid for whole house or duplex
@ABOSOLUTEKNOWLEDGE I have 1KW on the way:-)
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.
why would you plug in bulbs when you have the sun and without the sun you still have no light to power the bulbs
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.
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.
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.
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.
Thank you! I have this system in my class room for reference. Great Video!
