Q:solar panel??????????????
Solar electricity for single appliances high power is not easily available. By the time you fit the solar panel and all the technology to convert the power into the correct voltage and current, you may as well fit one which will provide for all electricity needs. I have a solar panel charger which can be used to provide power for direct current operated devices and they are a useful backup if your phone or iPod runs out of battery power whilst on the move. The UK energy saving trust has some great advice on how to reduce fuel costs and going green generally, but their major message is conserving energy, using less, is the best thing that you can do for the planet.
Q:what is the cost of a solar panel
With out the kW information of the need for your workshop no one can really tell you what you need for power supply. I would recommend you orientate your building or shop to maximize the passive solar potential. this will drastically eliminate your excessive need for heating and cooling. Which in turn will maximize your solar energy from the panels. Also depending upon what state you live in do some further research into any programs or grants offered by the power companies or state incentives. Regarding hydrogen...for get about it.
Q:How many Solar Panels do I need?
I okorder.com/... Home Power (magazine)
Q:solar panels for my home.?
Check your electric bill, and see how many kilo watt hours you have been using for the last year. That will give you a clue as to how many panels you will need in the array,and how many batteries you will need, what size inverter is needed plus would you want a true sine wave or modified.And that's just for starters. But of course you might get a break from your electric Co.(Rebate) also from your state,and possibly something from the Feds. I have installed on the travel trailer a 25 watt panel($850) a 22amp.charge controller ($45) a pair of Trojan 425 watt 6 volt batteries ($300 each) and a 2000 watt inverter modified sine wave ($2000).The only thing I can not run with this set up is the A/C which requires 3000 watts of power. So as you can see your project could get very expensive. I hope this sheds enough light on the subject for you.
Q:is it worth it to install solar panels?
The trouble is that it is so expensive to have installed and as you say it will take many years before you actually start saving above what the installation cost was, I personally would not go ahead and make that sort of investment, it would be more profitable to keep the money in a building society, get the interest from it and use that to pay for your electricity but the main thing that I have against solar Panels is that unless you stay in that house for at least twenty five years you will not reach the point where you are saving and to capitalise on it you would have to stay there for many years more, so you will not have the option of moving house without losing your investment and at the moment having solar panels does not increase the value of the property, it is just a good selling point, when you buy your new house, you would probably have to start all over again and then because of the years will never live long enough to reap any benefit from it.
Q:solar panel question?
Depending on the type of solar panel, any where from 6% to 42.8%.
Q:explanation of solar panels?
It depends upon your product. If it is a solar panel, I want to know if it is a photovoltaic panel or a thermal panel. If you don't know enough to know the difference for your question it might be somewhat difficult to suggest others should buy them. Products have to be marketed to a need either already felt or not so apparent. Photovoltaic panels supply an electric need and will offset electrical usage or may supply the grid if there is excess power. A discussion of payback periods including property values will be needed in any event. Thermal panels supply heat and hot water. They are more efficient than photovoltaic panels and will give faster payback times. (are cheaper) If you are a bit more specific more information may be possible.
Q:How much power does the solar panel produce?
I also doubt your claim of 4% efficiency. That strength solar panel is brand new technology (this year) and is not available in retail sizes yet. You probably got duped by some false marketing... In any case; even assuming you had a 4% solar panel, there are too many things for us to give you an accurate assessment of the power production. Clouds, location on earth, season, angle of the solar panel; these are all things we need to know to calculate it. Odds are it should have the average rate it produces electricity written on the back panel or with the instructions that came with it. I know of no solar panel retailers that do not also offer free installation. You should get your money back or get that free installation (and then you never have to worry about how much power it has, it just gets you what it can).
Q:Solar panel for macbook?
Well that's a good idea,,,here's what ya need..First you need an array that will overcome the drain effect created by the in use or sleeping laptop...that is best solved by averaging out the real use of the machine in terms of watt/minutes...If you check your transformer you'll see it has a capacity which you have cited however the true use of the computer is about 40-50 percent of that in watt/minutes..but only while your using it and when in the sleep mode the watt/minute value drops even more to about 5%.... So if your actual use consists of 2 hours of use per day at 50% and 2 hours at 5% percent the actual wattage draw is only averaged out at 34watts/minute. optimally your panel should supply all your power from its photovoltaic conversion ,but in the real world application the panel only recharges ,over a period of time, the used power. So if you had a 5 watt (@ 2vdc) panel working 480 minutes and used up 35 x2=700 and 9 x2=8 for a total of 78 watts you would have 5 x 480 = 7200 watts input and a parasitic load of 78 watts in the two hours...well within the recharge state required.. For a little safety I would permanently wire a cigarette lighter type plug to the end of the panel this will keep the polarity correct and serve as a quick disconnet means...Also add a fuse at .5 amp... a good place to get these are on the internet....some are very expensive some a very cheap --go for a middle of the roader...Have a good one from the E...
Q:Do solar panels add to global warming?
As far as it goes, you're right: putting up a big black object increases the total amount of energy absorbed from the sun. But that's only part of the story. If you didn't put up the solar panel, the same radiation would hit the earth. The earth already absorbs 2/3 or so of the energy that comes in (albedo .30), so adding even a perfectly black object increases it only by 50%. But it's not even that much, because most of the extra energy absorbed is converted into electricity. Solar panels are about 0-5% efficient, so half of the extra energy is turned into electricity rather than heat. Eventually it's put to use and turned into heat, but that heat was going to come from somewhere else anyway. (Even if it's just powering your DVD player, it turns into heat just the same as if you were using it to heat your house.) If you dig up a gallon of petroleum or fission a microgram of uranium, that's heat introduced into the earth's atmosphere. And these processes are inefficient: between generation and transmission you lose about 75% of the energy, meaning you've introduced 4 times as much energy into the atmosphere as you've actually used. So with a solar panel, you add extra heat to the earth by about 25% of incoming solar radiation, but you've offset external costs by about 45% of incoming solar radiation. The net effect is to cool the earth. And that assumes that the solar panel itself is perfectly black, which isn't the case. Real commercial solar panels have an albedo of about .35, which makes them more reflective than dirt and considerably more reflective than asphalt shingles, which have .03 albedo. In other words, even if you didn't actually use the solar panels for electricity, they'd be cooling the earth just by reflecting energy back into space more than your regular shingles.
