Product description

A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.


A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect.

In contrast, a solar thermal collector supplies heat by absorbing sunlight, for the purpose of either direct heating or indirect electrical power generation from heat. A "photoelectrolytic cell" (photoelectrochemical cell), on the other hand, refers either to a type of photovoltaic cell (like that developed by Edmond Becquerel and modern dye-sensitized solar cells), or to a device that splits water directly into hydrogen and oxygen using only solar illumination.

Q:Does anyone know a good company to buy solar panels from?
DRI Roofing. They are coming out with some of the best technology for solar panels. I know they have a different branch for the solar panel division, but i don't remember it right now.
Q:How much energy does it take to make, install, and eventually dispose of a solar panel?
The attached link is to an article from the 200 Home Power magazine. In that article the energy payback was found to be between 2 and 4 years. Newer panels are more efficient primarily because the silicon wafers used today are thinner. The silicon cell embodies most of the energy required to make a solar panel. Today most solar panels will produce the amount of energy required to manufacture them in between about 9 months and 2 years depending upon the specific technology used to make it. Solar panels are expected to produce energy for between 30 and 50 years. Therefore it takes around 5% of their total energy production to produce them. Note that these figures depend upon where the panels are installed. Panels in very sunny areas may generate more than 3 times the energy of panels in a cloudier area. Edit - The energy payback meta-study that carbonates references below mention one particular study Alsema (2000), which the authors used as a baseline to come up with their 4 year payback figure. These studies DO NOT assume ideal conditions. The Alsema study assumes an annual an irradiation of 700 kWh/m2/yr. That is the United States average irradiation and does take into account cloudy weather and the like. Under idea conditions the amount of energy collected can be almost twice as much. Albuquerque New Mexico is an example. The figures I mentioned above are recent values reported by several different panel manufacturers with whom I discussed the issue at the 2006 IEEE 4th World Conference on Photovoltaic Energy Conversion held this May. The very long payback times that carbonate highlights are almost certainly wrong. The study he references concludes that paybacks range between 2 and 8 years with 4 years being the most likely. In my opinion payback times are actually a fair bit shorter based on conversations with the manufacturers.
Q:Mono-crystalline or poly-crystalline solar panel?
All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.
Q:Does the new horizons has a solar panel for it power resources instead using nuclear generator?
No solar panel, and for the reason you stated - it is so far from the Sun that a solar panel would be of little use (and a lot of extra weight) at the distances where the primary part of the mission was being performed. The power source is called an RTG. We can think of it as similar to a nuclear-powered battery or a miniature nuclear power plant. As far as I know it is not intended to reach any other star. If it does, it's power will have long since depleted - and it would take thousands of years at its current speed to reach even the closest star. Closest star: Proxima Centauri, slightly more than 4 light years away. Current speed of New Horizons relative to the Sun: 4.52 km/s That's 0.000048 of the speed of light. It would take more than 20,000 years to reach Proxima Centauri *if* it were heading in that direction (which it is not).
Q:What is the cost of Solar Panels?

Q:What is the best solar panel?
your initial outlay for a solar panel is very large in terms of output.......somewhere around $4 a watt......ie you want a panel that will run a 00 watt lightbulb? $400.00 please. enough panels to collect enough energy to recharge a battery bank to run the house overnight? well, I've been doing a lot of research for my condo project in St Thomas and it comes out to 0-20,000 US $ for a bedroom apartment. Now, after about ten years you have made your investemnt back.... and there are a lot of government rebate programs that lower the cost.. what I have found is solar is nice, but depending on how far north you live you may only have 4 usable hours of light a day. you may very well be better with a wind generator.wind blows all the time after all...Bergy and SouthWest Windpower make two good small home units...start there
Q:How do you make solar panels?
it takes a ton of them to power a home most only put out 45 watts, [cheaper ones] solar is not cheap its more expensive than electricity
Q:Solar panel for your home?
These are all good questions but they are open Items. Solar panels work by the reaction of certain elements upon exposure to sunlight.The amount of power generated is Dependant on at least three factors; The size of the solar panel, the type of solar cells used (The specific element and the cell construction) and the amount of sunlight to which the panels are exposed. The answers to these questions may indicate how much you will save (How much does your electricity now cost per KWH and how much do you use in the two family house} and if solar is feasible in your location. You should probable contact at least three of the local companies that do solar installations and listen (with a cynical ear) to their presentations. They are all trying to sell you their product but you after listening to more than one presentation can sort through the BS. Also you might contact your present power provider. They should be able to give you some good advice on alternative energy availability. Good Luck DOCSRG
Q:Anyone have or know someone who has solar panels installed in their home? Is it worth getting?
and, if given the tax credits, you'll see a faster return on investment in CA than I would have in Western PA (I was given a 0 year return number without factoring any tax credits). Plus you'll be doing something good for the environment. My brother put his house for sale which had solar panels for hot water, and was offered good money for the solar panels independent of selling the house. If anyone has a any no answer that doesn't involve the initial expense, I'm looking forward to reading it.
Q:are there solar panel that work without the sun?
