I am trying to create a homemade circuit board to light LEDs. How many LEDs can this solar panel reasonably light up?

If you are lighting LED's in direct sun only with no batteries and the LED's you are using will run on 3V, then typically LED's draw 20mA, so it would light 3 of them if the above assumptions are true.

It really depends on the bulbs. It takes 3 bulbs up to 60 watts each. I put in (3) 25 watt equivalent LED bulbs and that lights up our entry way just fine.

I don't know the answer, as I don't recall finding that info. I can tell you I've been running 8 LEDs and (5) 7 watt fixtures for about a year with no problems.

There are some LED Panels, and Company has to let you know which one. Examples Lutron or Leviton brand... Here some models IP710-DLPA18036

The amount and (amperage) of the power supplies is determined by how many LEDS will be powered. I highly suggest calling the vendor. They are GREAT folks, and are more than accommodating. They make extension/jumper wires, to go between the segments. Also, if you have custom lengths (as I did) they will make one to your specifications.

See last answer about 2 LEDs out: but then considering the price, I can replace these once a year and consider it fine. 6 LEDs on one unit looks pretty much okay too.

You can create lighting systems of up to 24 light panels with one 2 amp power supply.

3 batteries should do it, but to be safe 4.600 watts of panels to be safe. In theory you should need 2, but real world use is what im going by.

It depends on how many amps you need. The solar panel can only out put a maximum of ~1 amp and 26 volts

No! My wife and I live in a small 1600 square foot home. We use all LED and CFL lightning and have just bought all energy efficient appliances. We have 2100 watts of solar (We can upgrade to 3100 watts on our system) and can supply 70 percent of our energy needs daily. We have 8 145 watt panels and 4 245 watt panels along with 5 kilowatts of pure sign inverters and 20 kilowatts of batteries. Hope this helps to answer your question.

All the LEDs will light up, you probably need an 2 amp charger, a regular 1 amp will be too slow for a battery this size.

I have 3 strips of LEDs(900 individual LEDs) and in total they take 17 amps. How are you getting 20 amps??There may be no need to double up at the terminals.

It calculates to 440 ohm 1/4 watt resistor. You may be able to use a 420. Are you really only using 1 resistor with the 12 volt supply? I would put more LEDs in series. Like 3 LEDs with 135 ohms. Or 4 in series with no resistor.

I think there is a 50/50 chance you could get it to work - But it puts out more than your smaller panel. I think other posters recommendation to check batteries is a great idea - every solar light I ever purchased, the batteries are what failed, not the solar.

I have two of these and both are on 15 amp circuits with other things is the practical answer. I have them controlling the 5m color LED light strips.The technical answer is that you would have to have 2,250 watts to pull 18 amps. But this is only a controller. It is not the power supply so it doesn't pull the power. It sits between the power supply and the light strips.

I don't have a tester to say for sure, but I counted 100 total 3 watt led lights on the panel. It's bright enough that you need to keep it at least 2 feet away from your plants, a little further seems Better to me. It will definitely cover a 3x4 area. My room to grow is 5x6 and I put 3 plants under each light, 2 lights side by side and my plants do very well and my electric bill hardly changed. So to really answer your question, I don't know, but 2 of these lights seem to do the same as a 600 watt hid light at about 10% of the monthly cost
