Q:Chem question regarding using solar panels ....?
It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
Q:Have a question about mobile homes and solar panels!!!?
My guess is that you will pick up everything concerning solar power at www.okorder.com.
Q:Do I need to run a ground form my solar panel?
Did you ever evaluate possessing the equipment your self? Why not take all of the tax incentives your self? Why pay an identical fee in 7 years from now? that may not a honest deal. Did you ever verify with them what might ensue once you want to sell your place before the tip of the lease? Our enterprise has put in photograph voltaic panel structures in 8 states in the Northeast and we adore to work out the tip consumer identifying to purchase the photograph voltaic array. we glance on the lease ideas as a final motel if there's a financing situation. the guy who owns it makes the money, short and easy. concerning utilising it whilst the capacity is going down, the inverters can not function whilst there is not any grid capacity. you may proceed to function utilising a battery equipment and yet another inverter, yet that will advance your fee extremely plenty as properly. you should use yet another generator as properly, which may be a less costly fee selection. you want somebody who's staring at on your appropriate interest, and not their very own investor. you've got your equipment value paid returned in basically some years!
Q:Solar Panel/Energy help?
The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
Q:how to build a solar panel?
Can you show us how to build a solar panel ?
Q:Any drawbacks for solar panels?
The largest drawback is the upfront investment you have to make for solar panels. There are some programs that allow you to finance the panels through your property assessment called PACE and leasing programs that can alleviate the large upfront cash outlay. Solar Panels have a lifespan of 30+ years. Since there are no mechanical parts, there is very little maintenance required. After 0-5 years, you will have to replace the inverter which converts the energy from DC to AC. This is a small cost in respect to the whole installation. The panels clean themselves well with just normal rain. With all the great federal and state incentives, the payback on solar is at it's all-time best. In Massachusetts, for example, the payback right now is 5 or 6 years -- then you would be making money for the next 25+. Another big potential drawback is that you must have the right site for solar to begin with. I'm a solar installer and I can tell you a lot of houses might not be right for solar. The best orientation is south, while southeast and southwest can work as well. The space must be unshaded and it would be best if it had few obstructions like chimneys, etc.
I think you need to take some basic courses on electricity. Usually, 8 volt solar panels are required to charge 2 volt batteries. The voltages of photovoltaic cells are set by the material they are made of, only current changes. If you hook up a 2 V solar panel to a 2 V battery, no current will flow, nothing would get charged. You would need some elaborate DC to DC voltage converters to charge a 2 V battery from 2 V solar panels. Solar panels can be connected in parallel or in series, as you've made the mistake of buying 2 V solar panel, you would have to wire them in series and have a charge controller that could limit the voltage of the charge. Did it ever occur to you that two 5 watt solar panels would not be able to provide the power needed by a 400 watt inverter? You're just running off your battery with your set up. Solar power is expensive power, you can not have solar without burning a hole in your wallet.
Q:Where can I get free solar panels?
I did the same thing recently, if you'd really like some free ones then you need to look for those little solar powered lamps that people put in their yards, theyre about 0 inches tall and people sometimes line the paths through their yard with them. Maybe you can find a neighbor who doesn't want theirs anymore, or you could check local dumps for them. They each have a solar panel in the top, and they can be linked together to make more power. Alternatively, you can look on OKorder for a pack of broken solar cells, which still work fine but don't put out quite as much power as they did when they were new. However, they are very cheap. Hope this helps.
Q:how do i fix my solar panel? please hurry i need it for my science fair project?
leave the car in the sun for a few hours to see if it charges. if not, the panel is defective. get it replaced b4 the science fair
Q:Solar panels for car fans?
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.
