I want to know that if I put solar panels in space if Pluto can recieve energy for iPods and television
Just to clarify, while the Sun superficially will look like a bight star from Pluto with no discernible disk, staring at it would damage your eyes. It still packs some punch even at Pluto's distance, but as others have so eloquently stated, installing solar panels on Pluto would be a tall engineering order for very little return.
I'm definitely no expert in the field but hope to learn much more in the future. I'm in the infancy stage of researching as many options as possible in the design and construction of a total green house. That being said, a particular local news story sparked my interest when they investigated the cost effectiveness of residential solar panel systems. Here in Austin, Texas, through subsidies and incentives offered, you can install a system that costs roughly 22.5k for about 7. Apparently these deductions come from a federal incentive (which is a very small portion) combined with those set by the city itself. Austin is a pretty progressive city so I imagine their incentives might be a little better than most but you can call your city's general info line (3) and do a little more digging. Another option you might have is renting the equipment. I was told yesterday that a company here in town would allow for the installation and use for a monthly rate. I know how tight cash can be in school and 7 thousand might not be tangible. The whole issue of energy conservation is so prevalent these days that new info is constantly coming out. Give your current energy provider a call and see what they can tell ya. I hope you find something that works for you. -G
Not really. Solar panels operate by sunlight knocking electrons off atoms, and there has to be a particular minimum of light in order to maintain a steady stream of electricity. Beyond Mars, we equip our probes with batteries and generators - because the sunlight at that distance is too weak to generate the electricity needed - so... no. Solar panels on Pluto won't charge anything....
Two problems: ) solar flux. Around Earth, we receive solar energy to the tune of 370 W/m^2 (watts per square metre). In theory, if you have a solar panel of metre by one metre and place it (in space) directly perpendicular to the rays of the sun (meaning = the panel is facing the sun perfectly), you should get 370 watts of power. In practice, the panels are never 00% efficient so that you get less. The flux (just like the intensity of light) drops as the square of the distance increases. Pluto is -- on average -- 39 times further from the Sun, therefore the flux there will be reduced by a fraction of 39^2 = 52 times 370 / 57 = 0.9 W Even with 00% efficiency, you square metre panel will produce less than one watt, once you get it out to Pluto. 2) temperature It is very difficult to built a solar panel (with all the required wire connections) that remains flexible enough at Pluto's temperatures. Temperature drops as the 4th root of the flux (or, to make it easier, the square root of the distance). sqrt(39) = 6.25 Temperature at Pluto = Temperature at Earth / 6.25 (in degrees Kelvin -- also known as Absolute Temperature) At best, temperature around here is 300 K (it is less than that, but 300 makes the calculation easier) 300 / 6.25 = 48 48 K = -225 C = -373 F wires and insulation become very brittle at these temperatures... and one watt of power flowing through the wires will NEVER be enough to warm them up (never mind running the iPod).
Yes. Not practical, but possible. Solar cells actually work best at low temperatures. At a little under W/m^2, it'd take a large solar panel to generate enough power for a TV (several tens to hundreds of Watts are needed). And, no offense meant, what TV programs do you think you'll be watching? You sound kind of stupid....
