Hi wasteoinc,yes, thanks for your reply and your explanations.Now I can start ordering the equipment I need.I look forward to reading your results, especially your views on the best method to connect the panels together
Hi, I found the technical specs at http://www.americas.fujielectric.com/sites/default...in English.I'm hoping someone can help me. I want to take equipment to Indonesia from Uk so that my friend (an electrician) can set it up for me on a houseboat I'm getting built but would like someone to check I'll be buying the right things.From what I've read on this page I think the equipment I want to take is a Fwave 92 panel (which can be cut into 4 pieces) and a solar charge controller http://s.aliexpress.com/myUvAZjM as suggested by Orngrimm.I will also need to buy some connectors (MC4 ?) and I can buy a 12v car battery when I get to Indo because of the weight.Does this sound ok ?I assume I have to buy a lead-acid battery because the specs for the solar controller say lead-acid although I'd prefer to buy a lithium battery if possible mainly because kids will also be on the houseboat and I feel Lithium would be a safer option. Is it possible to use a Lithium battery with this solar controller ? It sounds like I could take 2 panels if I wanted more power as long as they are cut up.I can take 30Kg luggage with me so could buy a Lithium battery here if I knew what to buy.Anything else I need ?Apologies for my questions. I don't know much about electrical equipment and would really appreciate any advice anyone can give.
hi, the tech specs from the fuji site are also in english and quite complete. its the diagrams and other details that are more helpfull in the japanese spec sheet.anyhow you got the idea correctly. With 92 watt panel you get 4 parts that you can connect in parallel. Lead Acid batteries are your best option as lithium batteries are too expensive for the same capacity, and a little bit more complex in charging. dont be afraid about the lead in the batteries as it stays inside the battery.the connections have to be a little bit self made. My best try until now is the flat tabbing wire , the thinner and more flexible the better. I will try self adhesive tinned copper tape in a few weeks, as soldering is very hard on these parts. I hope adhesive is less damaging to the wire in the bottom that its extremely thin and too much heat destroys ithotglueing the exposed wires works well, but my best bet anyhow is to fix the cable on some surface together with the panel (like a small piece of dibond). the idea behind it is to secure the wire on something other than the very fragile solder connectionI hope this helps, in a week or two I will post my results from using it in small (20x20cm) solar panel settings

my hypothesis is that you get some light (thus the increased voltage) but you dont get enough to provide the stated current.The way to test that calls for a resistor (same resistor) and then measure both the voltage AND the amperage on your experimental array and then the same on the control "normal" one. this way yo will get real wattage I dont want to rain on your parade, but your setup sound too good to be true. I m currently on vacation, so I cant test it myself
please forgive me for questioning, but the way I see you make the tests, suggests that you measure Open circuit Voltage . But open circuit voltage is quite misleading.even with minimal lighting solar panels reach quickly the open circuit voltage, ut they are not able to provide the stated current even 2000-3000 lux are enough to provide the open circuit voltage, but you need more than 20.000 to provide the state MAX current.the best way is to measure the solar panels under the same load and then calculate the wattage (voltage times current). If I am right I suspect you wont get these nice results that way.

really nice catch orngrim. This way you can have 10s of panels in parallel without fiddling into switching power supplies. If you cut the panels in four 17.5watt pieces you have two extra advantages.A. The whole panel needs no extra sealingB. You have leads coming out of the panels so you don't need to delaminate and solder the thin cables n the panels. The leads are short but much more sturdy
its those 320volt variety that is cheap. The rollable ones that are 33v or so still cost more than 150euros per ideal 100watt
hi cuyler1 . What is the yt?These panels are doing the rounds in ebay for more than 2 years now. The reason few people buy them is that they are not particularly hobby friendly and inverters that accept 400V are expensive. This instructable has the aim to make them more accessible.Most of the sellers I have seen are in UK, the netherlands and germany. Pollin.de has them for 55euros (just checked it, it says its finished you are unlucky because they had them for more than 2 years stably.but if you search a bit more, like here 69 euros, or 670euros if you want 10 from the same selleror here, (one unit)or this other seller has lots, and also I see now that he has found a quite cheap controler that accepts 400V for 75 euros (the next cheaper I have found was more than 300). He says its custom made, there are people who suggested to feed the 320V on the bridge rectifier of a switching power supply (230V AC RMS = 320V DC), but I havent tried it myself yet (im not so confortable with switching power supplies, I just know how they generally work.they pop up all the time, I dont know how , I dont know why , but they are here for some time now

thanks It was really nice, we made it together with a 4year old and she is very happy with her new night light.thanks again it was a nice project

¿Cuál es la finalidad de usar un cableado aparte en vez de el propio cableado de red electrica al que ya está conectado? ¿Por que no usas los PLC con sus forma de funcionamiento normal?Por ejemplo, yo vivo en un segundo piso y me puedo conectar a desde el garaje a internet con un PLC en casa y otro en el garaje, el cual comparte el mismo cuadro electrico que mi casa y está a nivel del suelo.
