Q:Is it worth getting solar panels fitted on my roof?
View okorder.com/. Too expensive and it may be illegal.
Q:Solar Panel energy 500 KW monthly?
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:Anyone who knows or has Solar Panels?
My sincere advice is forget about using a solar panel in your place. It is not suitable for your type of place.I am using three solar panel in my house. One is 30 watts driving an axial flow fan giving very good air for me and for my family people during day time. Another one is only 5 watts. Giving air for my face alone when I work on my lap top.Another 3 watts Panel I am using to determine the life of Panel that drives a mini motor for all the day time from the past 4 years.
Q:where I can find this solar panel?
How Solar Cells Work by Scott Aldous Inside This Article . Introduction to How Solar Cells Work 2. Photovoltaic Cells: Converting Photons to Electrons 3. How Silicon Makes a Solar Cell 4. Anatomy of a Solar Cell 5. Energy Loss in a Solar Cell 6. Solar-powering a House 7. Solving Solar-power Issues 8. Solar-power Pros and Cons 9. Lots More Information 0. See all Physical Science articles You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
Q:How many Watts of solar panels?
Running an oven or stove on solar is not a practicality; too much power is needed, use gas. Ditto, heating using solar electricity is not a practicality, and AC would also be asking a lot. The other things, within limits, might be do-able. You'll be needing as many solar panels as you can fit on. If I was you I'd consult a solar installer about how big your battery bank should be once you have decided how many Watts of panels you can put on.
Q:Any tips for protecting my solar panel from high winds?
You have to make the decision weather you want it portable or stationary. If you want stationary I would make some good brackets for them / search for cheap ones on OKorder. I'd have to see them to be able to offer any better suggestions. It's always hard to decide so you'll have to take notes and do research.
Q:How many Solar panels?
It depends on the size of the solar panels you are intending to use for this project. Do a quick search on google and you'll find plenty of information on what you are looking for. Good luck!
Q:Help choosing solar panels?
first okorder.com/ example: house roof is 20' x 20' 20' = 240, so sq. inches of roof is = 57,600 say rain fall for your area is 3 per month on average. 57,600 x 3 = 72,800 of rain collected. Using the conversion chart link above, that many cubic inches of water = 750 gallons of water free per month. Look at your water bill and see how much you use. Solar panels take on average 2-20 yrs to pay themselves off, just in time for them to be replaced. Paddle wheels go on for just about forever. We still find large paddle wheel mills in the USA that are over 200 yrs old, and still functioning.
Q:Solar Panel Watts?? help!?
This is not a precise analogy, but think of it this way: Volts is the pressure of the water in a pipe. Amps is the gallons per minute that come out. Watts is how much water you have after a certain length of time the pipe is open. a 200 watt solar panel under ideal conditions ( bright daylight between , say 0 am and 2 pm, held exactly flat to the sun ) will produce enough energy to run 2 00 watt light bulbs. You hardly ever have perfect bright sunlight; the length of the day varies during the year, and the angle of the panel to the sun changes from hour to hour; all this leads to a typical home in the US /Europe having only about 4 hours a day of maximum solar available. So, your 200 watt panel would give you 800 watts a day, enough to run one 00 watt light bulb for 8 hours If you are trying to run a house off solar, there are unfortunately other things needed between the panels and the lights / appliances; inverters, batteries, controllers sand each one eats up a little energy so you may get only 75 useful watts. See why more homes don't have panels? The other poster who said $30-50,000 to completely run a home on panels is about right.
Q:A question about solar panel?
I found some 0 square ft. solar panels that produce 30 watts . 3 watts per s.f. . A 2,000 s.f. home would consume around 2,000 kilowatt hours of electricity in summer months in areas that require air conditioning . This would require 67 kwh daily . You would need ,000 s.f. of panels and dozens of batteries to store the energy for night time .
