Q: In terms of efficiency and cost, what is the best solar panel. I am limited in the number of panels I can put up (probably 6-8) so they must be efficient, but cost is important also.What about these panels that can collect a wider range of light frequency?: your initial outlay for a solar panel is very large in terms of output.......somewhere around $4 a watt......ie you want a panel that will run a 00 watt lightbulb? $400.00 please. enough panels to collect enough energy to recharge a battery bank to run the house overnight? well, I've been doing a lot of research for my condo project in St Thomas and it comes out to 0-20,000 US $ for a bedroom apartment. Now, after about ten years you have made your investemnt back.... and there are a lot of government rebate programs that lower the cost.. what I have found is solar is nice, but depending on how far north you live you may only have 4 usable hours of light a day. you may very well be better with a wind generator.wind blows all the time after all...Bergy and SouthWest Windpower make two good small home units...start there

Q: how much would you pay for a 2'x4' solar panel that puts out 24 volts and 74 watts?: Try okorder

Q: Can solar panels be used to power a data center?: Yes, solar panels can be used to power a data center. By installing a sufficient number of solar panels, the energy generated from sunlight can be harnessed and converted into electricity to power the data center's operations. However, the feasibility of solely relying on solar power depends on factors such as the size of the data center, energy requirements, geographical location, and sunlight availability. To ensure a consistent power supply, additional energy storage systems or backup sources may be needed.

Q: What materials are solar panels made of?: Solar panels are typically made of silicon, which is a semiconductor material, along with other components such as metal frames, glass, and protective layers.

Q: What does it take to install the solar panel? Cable wires to power source or fuse box? Anything else?How does the cable wires stay on the solar panel?: How does the cable wires stay on the solar panel? With wire retention clips (4 per module) that are used to wrap the wire on the underside of the module frame. The home run cables to the transition box (converts between types of wire with no electrical transformation occuring) or combiner box (joins multiple source circuits in parallel, with the positives fused for safety) are usually tied along the racking system components, and with conduit sections used as needed. Racking is another big part of the installation. Don't just make your own homemade wooden rack, as these will weather away to nothing very easily, and cause great failures. GET a professionally designed metal racking system. PV modules are EXPENSIVE. Don't let the racking system cause them to break. It also requires the inverter, if you intend it to connect to the main electric service. If using multiple inverters, you need an AC combining panelboard to join them prior to entering the main electric service. Otherwise, you need to think about how else you might be using them. If you are charging batteries, you need a charge controller.

Q: I have made a 5v dc 52watt solar panel and I going to be trying to charger 4 2v dc 55ah batteries. I get about 6 hours of sun on my panel. Spec below, is that a big enough panel to charge the batteries???I have 30 3x6 solar cells wired together Cell Specifications: (Watts): .75 Wp (Amps): 3.5 Imax (Volts): 0.5 V max which is where I got my 5g 52watt max (if math is wrong plz tell me) The Battery type: 2Volt 55.0ah NB Sealed Lead Acid Battery. I am using a mppt solar charger.: I don't think so, but if it did, it would take a very long time. You need enough wattage or amps to push the power in the battery and 3w may not be enough. You would be better off with a small 2v battery, maybe the type they use for emergency lights. I would use a sealed battery for this type of setup because car batteries are designed for heavy charging with alternators from 60 amps and up.

Q: Hello, i want to ask whether if you could make an improvised version of solar panel made from an old CD or DVD?Is it possible or not?Please give me steps on how to make one if you know(put aside the one you see on quot;ehow: How to Make a Solar Panel From CDswhich says a bit confusing for me :( )Why not?: A solar electric panel? No. Solar electric cells, or more properly photovoltiac (PV) cells, are made from specially prepared (doped) wafers of silicon, much like transistors and diodes. CDs and DVDs are made from plastic plated with aluminum. They don't have anything to do with each other. Of course you can make a reflector out of CDs or DVDs, and you could use a bunch of them to focus sunlight on a water tank or something - this is called solar thermal generation. (That's what that ehow page is talking about, not generating electricity.) But there are much better things to use for mirrors.

Q: I am thinking of buying a 3w solar panel called the nomad 3 from goal zero. I want to charge 35Wh lithum batteries. I have heard that lithium batteries are temperatmental and without a regulated current things could get ugly.I have a couple of chargers that came with the batteries. One is a 2v car charger and another is 0-240v wall charger.Goal zero sell something called a sherpa 50, which contains rechargeable batteries and an inverster and I think they suggest that I charge my batteries indirectly through the Sherpa 50, however, the sherpa 50 is expensive at $200, and seems to have a small capacity, in addition to being extra weight that i don`t want to carry.Electronics geniuses, you are my only hope.: Lithium batteries do have special charging requirements. I would recommend that you use the 2 volt charger that came with them to keep them happy. Automotive power systems can have voltages as high as 4.5 volts when the engine is running so there's no need to limit the output of the panel to anything less than that. Check with the charger manufacturer to see what it will withstand. Some will work with systems up to 24 volts nominal (up to 29 volts actual) found in larger commercial vehicles such as trucks and busses. If your charger will work with both 2 and 24 volt systems you might not need anything extra to use the unregulated output of the panel. Otherwise I'd recommend a shunt regulator to clamp the output of the panel to no more than 4.5 volts. That way it would dissipate (waste) very little of the panel's power, and even that would only be during those rare times when the panel is producing maximum output. Such a device could be as simple as a high power zener diode, a low power zener coupled with a power transistor, or a precision shunt regulator such as a TL43 coupled with a power transistor. A more complex way would be a to use buck/boost regulator between the panel and your charger. You might gain a slight advantage under low light conditions when the panel isn't putting out much but the overall efficiency could end up worse than the simpler shunt regulator. Under optimum conditions, I would expect it to take a full day for a 3 watt (peak) panel to charge just one of your 35 Wh batteries. Charging an intermediate device such as the Sherpa 50 through its built in charger and then using it to charge your battery through yet another charger would severely cut your overall efficiency. Depending on how long you'll be gone, it might be far more practical, reliable, and economical to just carry (or find a way to be resupplied with) a few additional fully charged 35 Wh batteries. Don

Q: I have four power packs for solar lights. They have 3 AA .2volt batteries of 2450 mAh capacity installed in series for a total supply voltage of 4 volt maximum for the lights. I want to charge all four packs at once off a single 6 volt solar panel. With the four packs wired in parallel, what capacity output (wattage) panel do I need to charge the batteries in an 8 hour day?: Each battery pack has the equivalent of only 2450mAh capacity at 4 volts, so for 4 battery packs like that, a total capacity of 9800mAh. Assuming that the solar batteries have no charge left after being on all night, and that day charging time equals night discharging time, the theoretical wattage would be 9800mA times 6 volts = 59 watts. Of course, battery charging is not 00% efficient, so you need more wattage than that. Plus, solar panels are rated at peak output at midday, while at other times of day their output is less than rated. And, the charging in parallel isn't a good idea, because real batteries have different internal resistances, some batteries would become overcharged, while other packs wouldn't get the charge they need.

Q: Can solar panels be installed on train stations?: Yes, solar panels can be installed on train stations. In fact, many train stations around the world are adopting solar energy systems to power their operations and reduce their carbon footprint. Solar panels are installed on the roofs or canopies of train stations to harness sunlight and generate electricity, which can be used for lighting, heating, cooling, and other station facilities. This renewable energy source makes train stations more sustainable and helps in the transition towards a greener transportation system.
