Q:Solar Panel energy 500 KW monthly?
Replace your compression driven airconditioner with a gas fired absorption cycle air conditioner (there'll be a government subsidy or grant for that due to the R22 being phased out), install vacuum tube solar thermal collectors at a tenth the price of solar photovoltaics and use the hot water for the absorption cycle heat source with the natural gas burners as a backup. This avoids all the energy losses involved in the various energy conversions and solar thermal uses all wavelengths of solar energy while many photo-voltaics uses only one wavelength (newer dye based, multi layer, and quantum dot photovoltaics are all about using more than one wavelength of light). Solar thermal will also give you hot water and residential heating which are the other two big energy uses in a home. If you are bent on spending ten times the money on photovoltaics instead of solar thermal then figure out how many hours you actually run your AC for, use the filter replacement counter on your programmable thermostat to give you how long your fan is running in days and multiply that by 24 then divide your 500 kw/hrs by this value and since the power company only buys power from you at half the price that they will sell it to you at and you will have to buy power back at night, multiply by a fudge factor of say .5, this gives you a rough estimate of how many watts of solar panels you'll need to install in kilowatts, multiply this by 0,000 and that's roughly how much it will cost you in dollars (assuming $0 per watt installed, solar cells can be as low as $ per watt to manufacture but those aren't available yet and you also need to have them assembled into panels and installed so $0 per watt is a reasonable figure, people usually use values from $4 per watt through $9 per watt). Then after you get over the sticker shock, reconsider solar thermal.

Q:Cost of a solar panel?
That's more like a bare laminate, and will not be durable, but will get you a legitimate $/watt. Also understand that if a manufacturer has a cost of $/watt, that means the panel will cost more by the time you buy it. It has to be shipped, stocked somewhere, and the retailer has to make a profit. $560 is high for a 20-watt panel today. Whoever is selling at that price will not sell many, or will sell only to those who aren't shopping around.
Q:solar panel efficiency in space?
The mirrors might could desire to be on computerized monitoring gadgets so as that using fact the sunlight strikes it might keep the pondered sunlight on the panel with value of optical sensors and stepper automobiles and %s or laptop controllers then you definitely've the mirrors which destroy in hailstorms except you employ chrome metallic ones that in the process basic terms mirror 60% in assessment to 80% for glass To tutor what I say take a small hand mirror outdoors and prop it up so it reflects at one brick or spot on wall mark it or keep in mind it then wait or come lower back in 20 min see what proportion times it may be moved and how complicated the development of circulate
Q:Questions about the okorder.com solar panels?
I believe Earth4Energy to be a bald-faced scam, selling plans that will not do what is implied in the marketing, and imparting no information that is not publicly available on the internet, already. If you were to search for solar panel on torrent sites, most likely, some disgruntled customer has posted the material. It probably violates the E4E copyright, so I'm not suggesting that you get it in this manner. I'm going to skip many of your questions, given my already-stated opinion of Earth4Energy. Professionally-installed panels have a net cost of thousands of dollars in general. While they can save money (and Southern Cal is an ideal place for this), consider that it generally takes 0 years or more to get your money back. If you're on S Cal Edison, or SD Gas and Electric, you can go on net metering. They don't really pay you, they credit your electric bill. After a year, if you used more electricity than you generated, you pay them. If you generated more than you used, they reset the balance to zero and say thanks for your donation. You never really get a check, like in some other states. But you should have lower electric bills. You can put up panels for your own use without any certification. To put up panels professionally, you'll need a C-0 contractor's license from the state, or will need to be under the supervision of someone with such a license. But if it's the latter, you might just be the grunt that carries the panels off the truck and up the ladder, for minimum wage. I'd say better than 95% of residentail solar is connected to the grid, if the grid is available. It's a clear winner. Who wants to pay 50% more for their system, just to have batteries that need their water and acid checked all the time? Below is one of many unsatisfied customers from Earth4Energy. Be careful in your search, people selling these reports have bought up the keywords such as scam and ripoff to direct you back to sites selling the product.
Q:Charging batteries with a solar panel?
can I use a 2volt .5 amp solar panel on a 2 volt battery in a boat that i use for trolling motor and if I can can I leave it hooked up when using the trolling motor ? Plus how long would it take to charge a half drain battery with this panel??

Q:Solar panels for car fans?
You may not like it, but the answer's still the same. A car fan will draw anything from a few to several hundred watts, depending on which fan you're talking about (A/C, ventilation, cooling). A solar array will take up roughly one square meter to generate 00 Watts with the sun shining straight down onto it, so you'll need to cover (more or less) the entire roof (or hood) with solar cells in order to power that fan (minimum). If you still want to go ahead: Solar panels, Fuse, cables. Preferrably one cut-out diode per panel (in addition to the hopefully present internal diodes in the panels) in order to prevent one panle dumping its load into the next instead of into the fan. Much better option: get a low power fan (e.g a slow running computer fan) and connect it to that panel of yours. These fans make do with about 0 Watts (at a much lower air throughput), so you'll actually have a chance of running it from the solar panel without coverig your car in panels.
Q:solar panel model HELP!!!!!!!?
There are different types of solar panels. Photovoltaic for electricity, and thermal for heating water, and passive for heating air. So it would help if you would say what type you are going to build. Theere are a lot of videos on you tube on how to make solar panels. use the link below.
