Are solar panels a good idea in Seattle Wa?
- The solar rating of your area is Good so I wouldnt see the reason not to use it. In my area solar rating is very good I get all evergy from it plus even selling it. My payback time was very quick but... If you are not in a hurry or cant afford to spend a lot, wait till end of the next year when the new flexible panels are coming to the market. They are suppose to be a lot cheaper, enviromental friendly more effective than the ones on the market now. Check out MY Estimator. I think for USA users its the best help on the net. You'll see your costs, tax incentives can get info about local PRO's aswell. Often people are shy to ask quotes but solar is overpriced at the moment so spend your time finding the best deals. Also check where panels are made, their efficency; warranty is usually 20 to 25years. Surf the net- OKorder, OKorder then check companies who sell solar panels. Some even offer price fix if you see other place selling with better price. Good luck!s
How much was the price of solar panels 5 years ago compared to now?
- For just 5 years ago, certainly not! Perhaps you are thinking of 50 years ago, the kind that was put on the early communication satellites? 5 years ago, there was a glut of polysilicon, so modules were actually a little cheaper than today. Solar cell makers were basically using the scraps thrown away by chipmakers. But today, more silicon goes into making solar cells than computer chips, so that bonanza is gone. We will see prices going lower this year, possibly 20% from last year, because of improvements in technology, but also an increase in polysilicon supply, and a slowdown in demand due to worldwide recession. Later this year is a good time to buy panels, if you have the cash. The industry site below tracks module prices. They used to have more data, but I guess the old data rolls off the screen with time. If you want to see the details, they'll charge you for the report.s

What is the best low power alternative for TV set, to use as screen for dvd player, with a 30watt solar panel?
- Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.s
how does solar panels work?
- Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.s

Solar Panel questions...?
- I have a system that was installed last year. I have 20 panels which provide me with about 75% of my electricity. I do use less electricity than the average home. I use an average of 45 kwh in the summer, my neighbor uses more than double that. I paid $26K for the system, but I got a $0K rebate from my utility and the US gives a fed. tax credit. I am saving about $2K per year, so it will take just over 6 years to break even. I also have what I think is called net metering, my utility allows my meter to run backwards when I generate more energy than I use, so pretty much the entire time the sun is out in the summer. Having energy efficient appliances, reducing standby energy and using conservative climate control really helps keep my usage down. Weather striping, insulation and clean well maintained systems all help as well.s
are flexible solar panels possible?
- Yes it depends on the material of the bearings fixed, on the to be Moved pivots!/--Fulcrums/turning points/hinges.etc. but the wiring for commands has to reach them keeping them moveable in unhospitibale temperatures.The heating effect of an electric current is benificial too.s
