Q:How can I power 5v or .08 amps in a remote loaction via solar panel.?
Search the web for some of the inexpensive solar Cell Phone Chargers. They can be hooked in series or parallel as needed to get you teh voltage and current needed. The 80mA is not too tough, thats not much current. Suggestion is to use a battery that is constantly trickle-charged by the solar panel. This will assure operation on a cloudy day or at night. Another strange source for solar panels and solar charge systems is, believe it or not, Harbor Freight Tools. they are on the web as well as have stores all over.
Q:advice what solar panels to purchase?
Are you talking about buying panels, or investing in stock? LDK does not make panels, they make solar grade silicon that goes into panels. I haven't heard bad buzz recently about any brand of panel. Therefore, I would go by price per watt alone. If you type in solar panel price into Google, you're sure to get directed to the major sellers, each of whom will sell many brands of panels. There are a couple other requirements that I would have for a serious system: ) Safety certification such as UL. This will be legally required for a grid-tied system. All panels except the really fly-by-night brands and factory seconds have this. 2) 25-year performance warranty. It's standard now for a manufacturer to guarantee that their panel will still produce 80% of the rated output after 25 years. Older panels may say 20 years. Junk panels will have no such warranty, or something ridiculous like 90 days or year. 3) Crystalline silicon. Monocrystalline or polycrystalline doesn't matter. Every few years, someone claims that they have an amorphous or thin-film technology that's durable. Being conservative, I'm still waiting for such things to be proven. Some crystalline panels have been in service since the 70's, although they are pitifully weak by today's standards. I've heard good things about the Sanyo HIT hybrid panels, but that's only from one person who had them installed.
Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon cells in the laboratory to achieve the conversion efficiency of 24.7%. Ordinary commercial conversion efficiency of 10% -18%. Monocrystalline silicon solar cells because of the production process problems, generally its semi-silicon ingots for the cylindrical into, and then through the slice -> cleaning -> diffusion knot -> remove the dice -> the production of electrodes -> corrosion around -> Reflective film and other workers made of finished products. General monocrystalline silicon solar cells four corners for the fillet. Monocrystalline silicon solar cell thickness is generally 200uM-350uM thick, and now the production trend is to ultra-thin and efficient direction
Q:With everyone thinking green...how green are solar panels?
All kidding aside, you will possibly desire to do not forget that the White abode is the suited representation of the u . s . to the worldwide. because of fact of this that's equipped so vast and ambitious, and ambitious. image voltaic panels and wind generators will tutor a destructive connotation, form of like antennas on a boarding abode with wires putting down ought to characterize a ghetto to the castles and empires of the worldwide. there is likewise the reason for uninterrupted electricity throughout the time of an attack on the capital, it continues to be a area of the regulations of conflict you recognize. including option potential sources might supply a splash as to how the device works, or no remember if it somewhat is not that way, might come throughout the time of as being hypocritical, or purely for tutor (Like that's not being achieved now...)
Q:Do homemade solar panels really work?
My uncle has heated his large swimming pool for 40 years with a home made solar panel about the size of a car hood all made from scrap.
Q:how much energy does a 70x70 sq ft area of solar panels collect?
I'm putting in a $00,000 solar wind project on ST Thomas, Virgin Islands so I have some experience here..... ) depends on where you are...the further north the less efficient the panels are because early morning and late afternoon sun hitting at a great angle isn't anywhere near as good as noon hitting perpendicular..........the US Department of Energy has a solar calculator showing how many hours a day over the year you get enough sunlight to actually run the panels....in the Caribbean the answer is 6 so in Wisconsin you might only get 4 really usable hours a day, Nevada 5, Seattle...forget about it..... 2) the panels I'm putting in are ( roughly) 2 x 3 feet...you would need access around all four sides of a panel...you are NOT going to crawl 35 feet across an array to fix a unit in the middle......so lets say you get 35 panels tall ( 70/2) by 2 wide (3 foot with a 3 foot access area between each row = 72/6) or 420 panels. Each puts out 75 watts at max. So you are cranking out 73,500 watt hours, or 73kW. If your local utility buys back ( net metering ) the juice at, say, 20 cents a kWh, you get $4.75 an hour. If you have 4 usable hours a day x 365 x $4.74 you get back something like $20,000 a year. You pay about $7.00 a watt for a panel. The 75 watt panels are, rounding up, $200. each. Times the 420 panels number is $475,000 dollars. Add in about $2,000 for the inverter to change panel volts to power company volts, and maybe another $20,000 for installation you are looking at $500,000 AT LEAST to put in the system you propose. AT $20,000 a year in sales, its 20-25 years payback. Now, you can play with these numbers up and down but you still get the answer of A LOT of money to buy and build and a LONG time till payback.
Q:Does anyone know a company that will make custom solar panels?
There's no way that home built system that will generate enough power to run your home off the grid. That's all hogwash! No wind = no electricity generated. No sun = no electricity generated. I'm looking into a grid tie solar system. I'm still working out the math for my home. They are expensive ($20k - $50k) before tax credits, but they have been designed by engineers, not back yard, shade tree wanna-be engineers. They will put power into the grid during the day (making your meter run backwards) and you'll draw the power back at night (when there's no sun). This is perfectly legal. It must be installed by power company approved techs. That's how power companies are going to meet their green energy mandates for the future. You'll generate power for the power company and get paid wholesale prices for it (during the day). But you'll buy it back at retail (at night)
Q:solar panel efficiency in space?
I'm not sure on the exact numbers of solar panel efficiency, however i do know that at the radius of the Earth we should be receiving about 000W of power per square meter. This value is lessened by the atmosphere to a value closer to 600W per square meter on the Earth's surface. (on a really hot day) That's a 40% drop in power due to the atmosphere. I'm assuming that the solar panels being in space don't affect it's efficiency (as in mechanically). So its power generation should increase by about 40% when in space compared with a ground based panel of the same design. Hope this helps, Sorry it's kinda sketchy info...
Q:solar panel question?
Depends on the panel. On the order of 0% perhaps depending on you you measure it. More importantly, what they don't tell you is that more energy is consumed in the mining of necessary materials and the manufacturing process than one of the silly things can produce in a lifetime. Not that there isn't a place for solar panels. It just isn't a smart way to produce energy in large quantities just yet.
