Electroluminescent panels

Greetings, Anyone have any idea how electroluminescent (EL) panels are made? I see in this video https://www.instructables.com/id/Make-your-own-EL-wire-at-home/ that EL wire has a wire wrapped around another one, but what about EL panels.  They don't have wire wrapped around a sheet of copper, do they? Thanks

Solar Panels in Parallel? Answered

I know that you can wire solar panels together to combine the amps. But I've only ever seen this done with 2 identical panels.

Solar panel question

Hello i am long time lurker of instructables.com and i love the site and its inspired me to build a few things. that said onto my question.  i was at my local Dollar Tree Store (Dollar Store) and noticed the solar powered walkway lights. so i bought a few and decided i could salvage the solar panels.. so a few screws and some applied pressure later i have some small cells 35.6mm by 29.6mm with a model number (SC3630S-4N) and everything so i googled it and i get this website as the only one listing voltages and mA's but there are two sets and i am unsure which set i need to be aware of and exactly what it all means. http://www.aliexpress.com/product-fm/432233432-solar-cell-Embeded-Modules-Outdoors-wholesalers.html so any one can explain to me what the 4 values mean i know (V) is voltage and (mA) is amperage but why list them twice.

Solar panel uses??

Hey guys I'm needing the expert opinions of everyone here in the tech section. See I just mounted this 0.5 watt solar panel outside on a L bracket today (not just a couple tiny ones I pulled out of solar lanterns (does anyone want to see what it looks like mounted outside? I didn't think to take pictures until I got inside). Anyways, I've mounted it, ran the wire along the ground and in through my window (drilled a small hole below the window). Connectivity checks out good and I get about 20-21v and the full sun hasn't even hit it yet. The only thing is here though, this solar panel is meant as a trickle charging panel for car batteries and whatnot, and as such I only seem to be getting about 10-15ma (seriously wtf). I just resoldered this charging board from a solar lantern I had laying around, however I have a couple questions. I'm not entirely sure if this little board will handle the current/voltage (however it should as it's fairly low current from the solar panel) I've rigged up the board mostly like it was inside the solar lantern except longer/stronger wires. I have a switch on the positive line of the batt+ to the board. I soldered some thicker wires to the SOL connections on the board. Now I've seen a few of these and some are rather simplistic control boards and some actually have a bit of circuitry to them. This one appears to have resistors to current limit the LED (would be good so I don't blow it), however after following the traces on the board the led get's it's positive from that black transistor thing with 5 legs on it (what is that a power regulator?) The idea behind all of this here is that I can maybe charge up my cell with it or usb devices for example, but to have that come from a battery pack of AA's (to work as a buffer sorta-speak like a capacitor bank). I am a little miffled as how to make this work right the way I want it to. I would assume that once I get the battery pack situated I can disconnect the LED and use that connection for a charging cable, but then it would only provide power when theres no sunlight out (when you turn it on it turns the led on if there is no current coming from the solar panel). How can I do this guys I'm sorry to ask such stupid questions as I know to some of you's it's probably fairly mediocre but I'm a bit dumb.

Solar Panel Construction

Hello Everyone, this is my first forum post!I had a question and couldn't think of a better place to turn to than this.Basically, I am constructing, or planning to rather, an outdoor picnic table. I want to add some gadgetry to it and make it more multifunctional. Sorry to be vague, but a lot of it is still being worked out and since I'm going to post the project on here anyway, I'd like to wait to present the entire project as a whole.My question involves the use of solar panels as a table top surface. I have a basic understanding of how to create a solar panel powered system (http://www.rain.org/~philfear/how2solar.html or https://www.instructables.com/id/Solar-Power-System/). But my question is this: does covering the solar panel with a piece of acrylic hinder its power collecting abilities? I'm thinking of covering the entire table top surface of my table with solar panels. Aside from the obvious downfalls of people using the table and blocking sun, I thought there would be enough time when its not in use to collect power. But obviously I can't have people eating right on the panels and damaging them. Any guidance would be GREAT! I just want to know if I should even entertain this design idea or separate the panels from the table altogether. Thanks!

solar panels questions

In the quest to turn my garage 'green' I started with a purchase of a Sunforce 60 watt solar panel charging kit. I already own a 12v 15amp charge controller that I bought from Green Energies. The Green Energies controller is bigger than the kit supplied so I'm currently using this one. My questions; The Green Energies charge controller is supposed to have a blocking diode in it. When I put my volt meter on the leads going back to the panels (panels dis-connected, controller still hooked to battery) I'm getting approximately 10 volts. Should there be any reading at all? I went out this rainy morning to see if there was any power coming from my panels. To my surprise I read 8-10 volts (depending on cloud cover). This leads to my next question. It is worth adding a boost converter? I suspect the amperage would only be that of the incoming voltage, not what it is boosted up to.. Close? If my guess is correct, my 5amp (system at full power, rated at 24vdc), would only be about 1.6- 2 amps @ 8- 10 vdc. I also suspect the controller is stealing some amperage. 0.5 amps??? That should leave me with at least 1 amp coming in and giving me a 10 amp day. Not bad for a rainy day. Right, wrong or hopefully close? I'm not seeing my battery come up to full charge. I'm using a marine deep cell acid battery from my boat. Every 5 years I replace it to insure the boat will start as needed. Paddling that craft back to shore is not an option. One reason could be the fact of the battery being 5 years old and it will never get back to full. Second I believe would be the draw going back to the panels at night. Will the panels draw power?

Question about solar panel circuit

I'm putting together a solar powered cell phone charger and I need some advice from someone who knows a thing or two about photovoltaics. I've spent the better part of my free time the past three days or so absorbing as much information about electrical charging over USB and solar cell output as possible. I've seen a lot of helpful DIYs, and they would be great if I was following their method exactly. Unfortunately my project has serious space and power constraints. It's not for trickle charging an additional battery, it's for providing direct power to a USB phone. Here are my specifications. I need 5V and preferably ~500mA. Anything over 400mA should work fine. I *think* I've come up with a way to get that within my space requirements but I'm not positive it will work because I'm mixing two different size solar cells in one circuit. I can't seem to find a definitive answer as to whether or not this is OK, and what the results will be. I've attached a diagram of my plan. Two 5.5V/70mA solar cells wired in parallel with seven 1.5V/50mA cells. If I'm assuming correctly, this will give me an output of 5.5V (before the regulator) and 490mA. I don't know how or if the lower voltages of the smaller cells will effect the output. Can I use a combination of high voltage and high amperage cells in one circuit to get the output I need? I've talked with people in the Science and Tech forums and I've gotten a long way on the electrical circuit aspects and USB issues, but I'm hoping someone here will know a thing or two more about solar cells to tell me if my plan is viable as it is or if I will have to modify it. Thanks for any help.

Is My Solar Panel Design ok to achieve 60A charge rate for 1000AH 24V battery bank?

Please I need your advice on a propose project in my office. we have an Inverter (Xantrex TR2424- 24V 2.5KVA) which charge rate capability of 70A. The Inverter battery bank is rated 1000AH 24V total ( 2V 1000AH x 12 in series). I am sure of 5Hrs sunlight a day. and I want my project to charge the battery at 60A rate per hour. Our DC-current consumed when on Inverting mode is 26A DC (Approx 3A-4A AC inverter output). Our ac load on the inverter output is around 540W. In my design as attached, each group of PV (4pcs in parallel) should produce around 30A). total amperage should be around 90A. since during the day (sunny) we will be draining 26A continously from the battery, deducting that from the total pv current, we should have around 64A left to charge the battery bank. My request: kindly look into my propose design and advice where am wrong or need correction/adjustment and recommend with your experience. I assumed a DOD of 60% on the battery hoping to charge the battery to full capacity within 5 hours of sunlight daily. we have standby generator which we can power on to charge the battery in situation where it is cloudy. Thanks for your anticipated recommendation & advice

Voltage regulator for solar panel

I have built a solar panel as a fun little project, now it has come upon a big problem. The solar cells that I am using seem to have a higher amperage output and a lower voltage output in high intensity sun while having a high voltage and low amperage output in medium and low intensity sun. This poses a problem as my batteries were able to recharge during late winter and early spring but now are not able to recharge when there is the most energy to be captured during the summer. The average voltage during high intensity is about 11 while the voltage during medium or low is around 12.5 and 13. I want to know if there is a way to create a transformer to step up the voltage or create a voltage regulator that can withstand 13 amps so the battery can recharge properly. A link or any suggestions would help.
