- Q: I need to be able to charge a 2v 7amp battery with a solar panel. I understand that the charge controller will keep the battery from over charging/discharging, but what I don't understand is the amps.The solar panel is rated at 5watts.The solar panel comes with a 2v 3amp charge controller but will I need to buy a 7amp charge controller and replace it with that for my battery pack? Please explain. Thanks in advance.

- Q: So I want to power one of my car fans with some solar panels. I ordered quite a few and I want to power one of my fans under the hood. I've already disconnected the fan and pulled it out of the car to test it later.What all do I need besides the panels, fan, and wiring to make this work. This fan will not be tied to any other system. Currently, the fan is not operated by the car or any system of the car due to a modification made to the automobile allowing me to disconnect it from use months ago.Using the fan powered from the solar panels would help with the modification to increase air flow and speed into the area.Could someone please help me by telling me what else I need to make the fan operational from here?
- You may not like it, but the answer's still the same. A car fan will draw anything from a few to several hundred watts, depending on which fan you're talking about (A/C, ventilation, cooling). A solar array will take up roughly one square meter to generate 00 Watts with the sun shining straight down onto it, so you'll need to cover (more or less) the entire roof (or hood) with solar cells in order to power that fan (minimum). If you still want to go ahead: Solar panels, Fuse, cables. Preferrably one cut-out diode per panel (in addition to the hopefully present internal diodes in the panels) in order to prevent one panle dumping its load into the next instead of into the fan. Much better option: get a low power fan (e.g a slow running computer fan) and connect it to that panel of yours. These fans make do with about 0 Watts (at a much lower air throughput), so you'll actually have a chance of running it from the solar panel without coverig your car in panels.
- Q: I would like a list of the solar companies expanding or doing hiring or a good list in general. I know some are expanding. Best answer gets all the points
- damn I wish i could help you but I think the United States is too cool for solar I would move to Italy or Germany or China or India if you want a good solar job those guys know how to see into the future of energy
- Q: I bought a pack of OEM mini solar panels that produce 4.2v and 22mA and I was just wondering how many LED's I could hook up to one mini solar panel? I currently have one green LED with a resistor on the one panel but was wondering how many I could possibly run off of one panel?
- Typically LED's run off low voltage and 20mA or so of power (it depends what kind of led you have). That being said if one of your solar panels only provides 22mA of power then your circuit would have to be a series circuit for you to connect more than one. In a series circuit the current supplied of 22mA will go through each LED whereas a parallel circuit the current would be divided for each subsequential led. So in your case i can see you getting away with 3 or so led's before the voltage drop across each led will cause the voltage to be insufficient enough to drive anymore. Keep in mind the LED's will turn on but the first one will be bright then next one not as bright and so on. If you opted out and bought a solar panel with 200mA and 4V you could wire the led's in parallel and get 0 led's to turn on with the same brightness or intensity. Hoped that helped!
- Q: Can solar panels be installed on agricultural or farming operations?
- Yes, solar panels can be installed on agricultural or farming operations. In fact, many farmers and agricultural businesses are increasingly adopting solar energy as a sustainable and cost-effective solution to power their operations. Solar panels can be mounted on rooftops, open land, or even on barns and sheds, providing clean and renewable energy to offset electricity costs and reduce carbon emissions. Additionally, solar panels can help farmers take advantage of unused or underutilized land, providing dual benefits of energy generation and agricultural productivity.
- Q: Hello everybody, the area we are living has energy crises with no electricity available most of the time. What I am thinking is to buy a solar panel with other required accessories. Please note we have normally long sunny days most of the time during a year.Please advice installing solar energy system would supply energy 24/7? I have a television, a dvd player, a fan, 4 energy saver lights (2 watt each) and a laptop. Please also advice the specifications for the system to be installed and the points I need to ensure at the time of purchase. I think of buying a solid battery (not acidic battery)The forum is open for your kind suggestions.Thanks!

- Q: what percentage of sunlight is converted into electrical energy in a solar panel?
- Depending on the type of solar panel, any where from 6% to 42.8%.
- Q: I purchased some small 3.6 v 70mA solar panels online. I have no experience with solar panels. I am confident of the layout of the parallel circuit I want to create, however I don't know how to properly connect the tabs that come from the sides of the panels. Any help on connecting them?
- Okay okorder /... That metal strip up top is negative, if you turn it around and look on the back you will see another metal strip there which would be positive. When it comes to wire, I use 24awg audio wire I got from radio shack, they only have solid wire at this gauge at my local radio shack but stranded is preferable. Solar cells are super fragile too so you're going to want to be extra careful. I then take a length of stripped wire and lay it over the silver tab, I hold it in place with some electrical tape at each end. Here is where experience comes into play, you can't use just any solder when making these connections. Well, you can but it takes a hell of a lot more time and effort to get it right. Make sure to use 96/4 silver-bearing solder. I'm not sure why but 60/40 solder does not adhere very well to the cell and usually the soldering iron has to stay on the cell for far too long which ends up discoloring it. If you need help on how to solder send me a message, you need to know how to properly tin the iron, since this is such a meticulous and unforgiving soldering job.
- Q: i need as many bad things there is about solar panels
- They require the use of Silicon which requires refining. This process of refining uses non-ecofriendly chemicals. It damages the environment. Solar panels are only about 20-30% efficient whereas coal is around 60-70%. Solar panels require much space for such small output. Do note, that new solar panels are being worked on and that with the correct alignment of solar cells, solar panels may become ~80% efficient, rendering coal useless.
