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.s
Solar panels produce electricity. This one isn't very good. $500 for only 80W with such a large panel? It doesn't even come with a battery (car battery) If you're thinking of something to try and run your house off of, you'll need somewhere between 2 to 24 of these panels, plus a voltage converter and other equipment to connect it into the electrical system in your house. If you want something to help charge a cellphone, I guess this would work - if you could get the electrical connections set up properly - but it's still awfully expensive and won't give you a return on investment for somewhere between 5 to 20 years - by which time the panel will need to be replaced, and we'll (hopefully!) have more efficient panels available.s
You can't really judge the watts for solar lighting the same way you could for dc lighting. This is because of several factors The lights that you showed ARE NOT high quality lights and furthermore; they are not a well-known brand. Also, I would be suspicious of any store that offers lights for less than half of what other stores do. They are dumping the merchandise, which means it could have been sitting around for a while. MAXSA Innovations makes good solar lamps, so does Solar Goes Green. As the other responder wrote, you are better off using dedicated solar spot lights or floodlights than trying to integrate a solar panel into regular solar lights. A 00 Watt solar panel is pretty strong, and you also would need a battery. Unless you know how to rig up the system with appropriate controllers to make sure too much energy doesn't get into the rechargeable battery (lithium ion or NiMH), you take a risk on having the whole system fry out.s
It's not a matter of Federal money or Federal programs or attitudes of the government that keeps your grand plan for generating large amounts of electrical power using solar panel systems and distributing it country wide with fiber optics from becoming a reality. It's technology. Whatever optimistic speculations you may have heard or read, large scale, dependable generation of electrical power at steady high levels from solar cells is nowhere near a reality. Some of the big culprits are the variable atmosphere of the earth and the inefficiency of practical and economic solar cells. The conversion does not depend on the warmth of the states where generation might take place but on constant direct sunlight, unobscured by clouds in the atmosphere for most of every day, and on high efficiency solar cells. No states can depend on clear skies 365 days of the year and there's the little matter of night time, when nothing would be generated. Also, the electricity generated by solar panels cannot be carried by fiber optics since they carry electromagnetic energy (light), not electricity. What may be possible sometime in the not-too-distant future is the use of solar panels to supplement, not replace, conventional power generating systems on a local basis. It would not be required that they provide constant high levels of power every day, but only that they provide power when conditions were right, in order to perform the valuable role of cutting down on the use of fossil fuels in conventional generating systems. (The direct current generated by solar panels would have to be converted to alternating current or stored in batteries to accommodate our present methods and equipment for using electric power.) As soon as this becomes technically and economically feasible, we will not have to wait long to hear about it from the energy corporations and politicians.s
silicon based photovoltaic cells used some boron as dopant. i dont understand if that helps supress proton pastime, the way they be conscious boron on supressing run away nuclear reaction.... im clueless as yous
