Q:how many 45 watt solar panels would I need?
I doubt you will be able to get anywhere near the amount of light needed to run anything for 6 hours a day. You will probably need a battery or something as well. At the least, you will need 3 solar panels, but you will probably need more than that in order to charge the batteries to get it to last long enough.
Q:Solar Panel Efficiency?
Depends where you live. Each kWp will generate in a year about 750kWh in northern England, or 900kWh in the south. About ,00kWh in the south of Germany or up to 2,200 kWh in the Californian desert. The farther you are from the equator, the bigger the difference between summer and winter months: in S California summer months may only generate 2 times as much electricity as winter months. In the UK it can be 4-5 times as much. 200 W is 0.2 kWp so divide the numbers I gave by 5 and then divide by 2 to get the 'average' month - you really need to look up 'insolation tables' for your area though!
Q:Will my 8watt solar panel charge a car battery and how fast?
welcome to the wonderfull world of solar! you probably have a 2Vdc 8 Watt solar panel, to figure out its charging amps capability we do this equation Watts/Volts=Amps 8watts/2Vdc=.5Amps this is a conservative figure, since solar panel ratings are calculated using winter time sunlight, sunny locations and more daytime hours will give you higher amps. a typical good condition car battery is rated at 40Ah (Amp hours).to find out the charge time, we use the following formula; Amp Hours/Amps=T where T is time in hours 40Ah/.5A=26hours this is charge for a single battery, two batteries will double to over 52 hours. lets compare to charging a battery with your car, a car alternator puts out about 60 amps but usually run about half capacity. 40Ah/30amps=.3Hours! An alternator is far more efficient so charging with a small solar panel is best as an alternative or for low power applications. As far as using an inverter to power a TV, we can calculate how long the battery will last by using the original formula. a typical 9tv will use 70 watts 70watts/2Vdc=5.8A 40Ah/5.8A=6.9hours this figure is by drawing all the power from the battery, voltage inverters have a safety feature that will not let you discharge your battery all the way, so 40Ah battery will power a 9 tv for about 4.5 to 5 hours.
Q:Powering my house with solar panels?
We are installing a 3.3 kWh system on a 2 story house. Really three story if you add in the basement. It will provide about 3/4 of the electric power they use per year. The cost of the complete system installed is in the $26,000 range. A 4.5 kWh system would wipe out their bill and would cost in the $34,000 range installed. But it had too many solar modules to fit on the roof. Now if you are wanting to go off grid in the average American home you would spend about $60,000 easy. Most American family's are very very waste full. Very few even have CFL lighting and leave every light in the house on. I have even known of some that will use a 60 watt night light when it is so easy to put in a CFL or a 4 watt night light. With 4 TV sets running in most homes at the same time a 200 watt stereo system for background noise.. Well we Americans have a long ways to go yet.
Q:What does it mean when a solar panel is 50 watts?
Solar okorder.com/
Q:how fast does a 25watt solar panel generate power to a battery?
To figure our how many you need, take a look at your power bill. It will tell you how many kilowatt/hours you used during the month. My bill says I use about 2000 kilowatt/hours per month, or about 2000 kwh /30 days=67 kw/h hours per day. That is 67,000 watt hours. To supply that with solar panels, you have to generate at least 67,000 watt hours, but you don't have a full day to do it, since you have to do it while the sun is up. So you put the energy into batteries during the day, so you can use it at night. A 25 watt panel generates about 25 watts when fully illuminated by the sun. If you fully illuminate it for an hour, you get 25 watt hours. If you get 2 hours of sunlight a day, that would seem to imply that I need 67000 watt hours/25 watts /2 hours=45 panels. But for most of the day, the sun isn't hitting the panel fully, so it isn't going to generate the full 25 watts. When the sun is 45 degrees to the side, you only get about 70%. When the sun is 60 deg to the side, you only get 50%. And what do you do on cloudy days? And the shorter days in the winter? To make up for this, you have to increase the number of panels to make up for the loss. So in reality, I might need double this number of panels, for realiable solar power throughout the year. That works out to about 90 panels, or ,250 watts worth for my house.
Q:Why do people use solar panels?
It turns energy from the Sun directly into usable electricity and is very useful if you are far away from the power grid or want an alternative electricity source. Since energy prices must steadily rise and Solar cells are getting cheaper, it is likely that in several years Solar panels will provide electricity as cheaply as the big power companies who maintain our power grid.
Q:What specification of solar panel do I need?
Ive been employing the comparable photograph voltaic panels for 5 years, have flow some instances so as that they final lots longer than the roofs weve had over us. i'm coaching my young ones a thank you to construct wind turbines, because of the fact we shop having potential failiures whilst the wind blows. and recently its have been given very windy. I can charge banks of battery's and shop my place of work working from dc-ac converters.
Q:Question about home solar panel systems?
There okorder.com Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:are flexible solar panels possible?
Yes it depends on the material of the bearings fixed, on the to be Moved pivots!/--Fulcrums/turning points/hinges.etc. but the wiring for commands has to reach them keeping them moveable in unhospitibale temperatures.The heating effect of an electric current is benificial too.
