Product Description:

  Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells. These early solar modules were first used in space in 1958.

Q:Are you a solar panel specialist?
No, just an amateur. I guess that could be called an Enthusiast. I think most people find the topic somewhat interesting, some more than others. Why do you ask?
Q:Solar Battery System?
A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
Q:How Much Do BP Solar Panels Cost In The Wholesale US Market?
Wholesale prices for BP solar panels range between $335 for the 40 watts panel to $835 for the 70 watts panel. Here's a brief listing of wholesale prices for BP solar models: - BP340J solar panel (40 watts) @ $335 - BP350J solar panel (50 watts) @ $37 - BP375J solar panel (80 watts) @ $504 Right now I'm getting a series of 50 watt (7.5 volts) panels installed in my house. It's a start to reduce dependence on electricity bills and try get some tax rebates as well.
Q:how the power output of solar panels fitted to a house can charge?
Solar panels do NOT get charged, so the question is junk, or you misstated it. Solar panels are used to charge a battery bank, which stores energy for times when there is no sun. Then energy from the batteries is used, via an inverter, to power appliances in the house. OR do you mean how the power output of solar panels can CHANGE? In that case, they change when the sun moves, such as behind a cloud, or just changes angle in the sky, or goes out.
Q:kilowatt solar panel help?
You would be amazed how often I have answered this question. The answer is that it depends on your latitude and local weather . Let's see if I can give you enough information so that you can determine the answer for yourself. A kW solar panel is rated at kW when it is exposed to a solar flux of kW/m^2 (called a peak sun hour). There are readily available tables of effective peak sun hours per day by city (see Reference ). Let's use Fairbanks, AK as an example (it is the first line of the table). Fairbanks get an average of 3.99 of peak sun hours per day on average. So your panel would produce 3.99 kW*hr per day on average.
Q:Question about using solar panels......?
I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
Q:Does anyone know a company that will make custom solar panels?
okorder.com Other sources available on the first Link also. Wingman
Q:What's the best deal for Solar Energy panels for your home?
you have been very mislead by someone. Or ? did you listen to a Obama speech or something ? EDIT ; thanks for response via e mail. But if you think you can save money by, renting solar panels , then you are a very ignorant person. The only way that a scheme would would work ,is if the company that is leasing the panels to you ,,have bribed lobbied the local or fed politicians to get subsidized to provide the panels. then they get payed to install them and guaranteed to make a profit by the gov. for green energy that is why you have to pay 25 cents , while most people pay 0 cents , because you subsidizing all the profits of these Professional thieves. Who's job is to find new ways to get into that deep pool of public dollars,,tax dollars . Question for you .. Do really think the rented solar panels will? ) pay for installation 2) pay for the cost to buy the panes 3) pay the sales commission to the people that sold it to you 4) pay the on going commission to those that over see them 5) Add to that the higher rate on your elec bill to pay for these people to be subsidized , so they can rent you some solar panels ??????? Like I said ,,,,,,,you must be very ignorant about energy. Or very Ignorant about the thousands of companies that are formed to succk tit of the tax payers. You are ignorant on both of those points. So dont get piisssed of at me for answering your question !!!!! Instead , you should ask why you are so easily led ? Why you are so easily fooled by the users ? That is those that use the gov to use ignorant people like you. HAHAHAAH. And you fell for the whole scam without even realizing it That is why I use the word ignorant ,, because you are. If you dont know what ignorant means google it to find out. because you are,
Q:how can i build my own, cheap, solar panels at home?
Build from scratch, sorry your way over your head. (mine too). There are lots of companies that will give quotes on doing what your looking for, but plan on spending 20 to 50K depending on where you live and what you need. I don't know about where you are, but My hydro bill is almost half delivery charges. Therefore I could cut back by 99% on the usage, and still only have my bill come down by less than 50%. I understand you desire to lower costs, but unless you do a big change(lots of outlay) your savings will be small. By all means shut off lights your not useing etc. there are other ways of lowering your household bills better way is solar heating. But this also depends on where you live. I'm building a solar collector for 2 houses , Contact me at davethree@persona.ca and I'll pass on more info
Q:What is the most powerful solar panel made?
There are various solar farms that run turbine generators that have some rather large arrays. I suspect they'd be in the southwest but i've seen pictures of them covering a few acres. You won't find very large panels because its best to keep the panels small and just have a lot of them. This is because its much easier to have a thousand 0m^3 panels then huge 0000m^3 panel because you achieve best performance when you can align the solar panels to always face the sun. With a huge panel, you would need it to be high off the ground so it can manuver around. Small ones can all be menuvered on a small scale only a few feet off the ground so they can all be pointing towards the sun to gather the most light.
