Q:Whats the annual energy output of the average solar panel.?
The output of a solar panel would depend on your location and panel size. Most solar panels are rated using 000 Watts per square metre from the sun. This is only possible at the equator. Some supplier have online estimators for output depending on your location. Solar panels rate up to about 250 Watts per panel. I have an online calculator to work out the costs and benefits of solar. You can compare the costs of solar setup and 25 years of electricity versus buying from the grid.
Q:Where to buy cheap solar panels?
Grimcho..I'm going to give you a secret that no-one I know of has ever spoken of..Call Your local railroad maintenance yard and/or your local oil production company..I know your probably in another part of the world where this will not apply but here its like this.. BNSF changes out every 2-5 years their 00w 24v panels...they still have a good 5years of lifetime..Oil companies change them out on their well sites every 2 years 2x 60w 24v (actually they are 2 +2vdc grids series) now if your in Italy sorry this didn't work but if your in New Mexico ..they are in Santa FE...also they have way good batteries that are wet cell and run about 600$ each that they just dump many times on the guy for asking..try it....From the E....
Q:Feedback on Solar Panels?
Solar panels are very good. Although they may start off expensive, they will soon make up for the money spent. But they will only be useful when facing south and in sunny-ish countries. :)
Q:Why only Photo-Voltaic solar panels?
I agree with you John and for the same reason already put forth as a negative. Solar thermal is a more mature technology. This is the reason why I spent so much of the last winter studying it. I can be reasonably sure that what I learn will not be obsolete tomorrow with a new technological breakthrough. I built a solar addition/greenhouse to personally study the effects. So solar thermal panels are not the only way to go. With respect to electrical production. I have seen parabolic reflectors coupled to stirling engines and solar thermal trough heaters used to supplement steam generation for alternatively gas fired steam / electrical generation plants. On a trip to China over 4 years ago I noticed solar hot water vacuum tube collectors being sold in their local hardware and big box style stores. These were gravity fed package units intended to have the tank on the roof with a supplemental electric backup. The vacuum tube collectors seem to be one of the latest innovations in this technology. Using phase change materials temperatures in these panels can be produced in excess of 400 deg F. and they are useful in colder temps and on cloudy days. While they are still costly for many applications, I have been discussing the use of vacuum tube collectors with the owner of a laundrymat. Solar thermal will not pay back as well as conservation in many cases of older construction, but it currently seems better than photovoltaic panels. Solar thermal requires more understanding of systems and relative efficiencies. In one way solar thermal is more like the electric car while the internal combusion engine is like photovoltaic. The idea of producing electricity from the sun is a sexier idea. It is also more in line with our paridigm of: just producing lots of energy and to H with any conservation efforts. For that reason it seems to get more press.
Q:How are these flexible solar panels?
but it's very interesting and I wanted to ask you. In your case this is good solution, but I saw flexible panels in OKorder much cheaper than 250$. This is the price of standard solar panel 20w. Maybe your panels with better efficiency? I know that flexible panels are less than half efficient than regular panels, thats why you need twise more area to get the same output. What is your usage of this energy in this van? I know there are many ideas of solar cars, but if this solution is efficent enough today? Thanks!
Q:how efficient are flexible solar panels?
One I got about 3 years ago is about 50% as efficient as a glass panel I got about 0 years ago. Not exactly a scientific study, I know.
Q:Are solar panels worth it?
No, but if you have the money, go for it. In Germany, people get a government rebate (much like the Prius rebate our own government offered) and so you see solar panels everywhere. If the Obama administration pushes for a rebate for solar panels, you will see them here in the state. It's the initial cost that puts off most potential solar panel customers. Upkeep isn't too expensive, and they ultimatley pay for themselves. (after about a decade)
Q:What can a watt solar panel power?
You can run a lot of things. If you set the system to charge batteries when you are not using anything, they will charge effectively. You can use the system for lighting, LED lighting direct from the battery power is most effient since LEDs are low voltage devices with a very long life span. I replaced a 2 tube flourescent trough with four 5Watt PowerLEDs for example, While I have it on 20VAC at the moment, I can move it to 2 VDC power with ease, and had set it up to run initially on 2 volt sources. There are also many 2 volt appliances as well. You can even convert some of those all in one stereo systems to operate on 2 volts by eliminating the power supply. You will actually use less power by doing so. You will not be able to blow the shingles off the roof unless you add a Class D amplifier to the output, but for most listening, the output is adequate. Some small TV's these days can be run from 2 volt sources, if not directly, then with a buckboost inverter for a laptop. The small TVs only draw about 30 to 45 Watts. Skip the idea of using an inverter, they are not efficient at small loads, and represent additional load on the system. So with a little bit of planning, you can run a lot from that 60 Watt system. You can at least take some bite out of the electric bill for mundane lighting. You can also use them to keep power up on a battery system for lighting in a remote barn. The uses are only limited by your imagination and creativity.
Q:simple definition of how a solar panel works?

Q:how to design a solar panel to store energy and convert it into electrical energy?
solar panels change light into electricity, and do NOT store power. You need a solar panel capable of enough power to keep the light on all night. And that may be 6 hours of sun and 2 hours of dark. Then you need a set of batteries large enough to hold that energy. And a charge controller to regulate the charge into the batteries. And then a light that will operate on the battery voltage, say 2 volts. This is probably not practical due to the large solar panel required, and the large batteries. But here is a few numbers. Assume a 00 watt light at 2 volts. Assume you get at least 6 hours of sun every day and the light will be on for 2 hours. That means the battery has to store 00*2=200 watt hours. divide by 2 and that is 00 amp-hours, a large auto battery size. Allowing for 20% losses in the battery and circuitry, that means you nee 400 watt hours from the solar panel. Since it has 4 hours to operate, that means it has to deliver 400/4 = 350 watts at 5 volts. So there it is: 350 watt panel 00 amp hour battery charge controller sized for above 00 watt light. If you have to allow for a day with no sun, then you need more batteries. Two nights means 2400 watt-hours, two batteries, a larger charge controller and a 2800/4 = 700 watt panel. cost: $400 for batteries $200 for charge controller $2000 for panel .
