- Q: Why would someone use a solar panel? Does it have to do with the economy right now, global warming, or what?
- I doubt the immediate economy has much to do with it. Solar panels require long-term investment, so in hard times, someone having trouble making ends meet is not going to be buying solar panels, when they could be buying food. It's like if someone has a gas guzzler, if they get laid off, they're not going to spend their savings on a new, fuel efficient car, even if it saves money in the long term. However, it's generally the more wealthy that install solar, and they're not impacted as much by a slow economy. Human nature being what it is, I doubt many people install solar to save the planet. There will be some, but I suspect most are interested in the long-term financial savings. I'm kind of unusual, in that our panels are break-even financially at best. The main reason I put them up was for the fun of learning and doing it.
- Q: Are there any health risks associated with solar panels?
- No, there are no significant health risks associated with solar panels. Solar panels do not emit any harmful substances or pollutants that could pose a threat to human health. However, it is important to handle and install them properly to avoid any potential accidents or injuries.
- Q: I jotted down some notes for my Technology and Architecture class and I'm trying to figure out what i meant when i said 'Treated with gases at extremely high temperatures.' I have NO idea what I was talking about :) Im trying to figure out if what I am talking about is about Silicon, Polychristaline, or a Solar Cell/Panel.
- Let me help you get an idea of what you are talking about as your notes seems a bit jumbled. Mostly when they refer to a silicon solar cell they mean that the silicon is one crystal of silicon. (very much like a diamond, but with atoms of silicon instead of carbon). A single perfect crystal of silicon can be grown that is very large at temperatures near the melting point of silicon or around 400C and then is sawed up to create electronics or solor cells. Polycrystalline :) solar cells are also made of silicon, but instead of a single crystal it is made of a jumble of small crystals that have different sizes and directions. So these types of solar cells can be made using a silicon gas (siline: SiH4) at much lower temperatures 600-700C. So these are less expensive to make, but because they are not perfect crystals a poly solar panel that is the same size as a crystalline solar panel will make less energy. I hope that helps.
- Q: I need to reduce the average monthly home electricity bill by powering some of the household appliances using solar panels. Can I use a 250 watt solar panel to power a medium sized upright fridge?
- Solar panel alone? No. With the appropriate storage system and inverter, perhaps. You will need to do the calculation - as follows: In a solar day that averages about eight hours, you will generate about 67% of your rated output over those 8 hours. That means you will have made 340 watts. Your refrigerator will run for about four (4) hours per day on average if you are very careful about opening and closing. If you have a 400-watt (average-when-running) fridge, you will have a small cushion that will be absorbed by inverter losses, charger losses and so forth. So, with an adequate set of storage batteries, a good charger and a good inverter, you just might be able to operate that small fridge. No icemaker, no other power drains. But, two 250-watt panels would be better.
- Q: How much solar energy does a 2m by a 3m solar panel convert to energy on a sunny day? Assume that the solar cells are 30% efficient.I'm not looking for the answer so much as I need an explanation o how to solve this type of problem... Thanks!!
- A watt is the fee at which vigour is produced. It's analogous with horsepower, hp = 745W= 33,000 toes-lbs per minute. So the wattage of a sunlight panel is the capacity of the panel to drive a procedure like run a motor or power a radio. General energy calculations are a part of the bigger class of Physics.
- Q: What is the average annual energy output of solar panels that can be installed on the home?
- The Sun provides about 360 W per square meter above the atmosphere (Solar Constant). Approximately 2/3 of the energy is lost in passing through the atmosphere, which means you should anticipate at best about 450 W per square meter arriving at a solar panel directly facing the Sun on a clear day. You can anticipate an efficiency of approximately 30% for a typical solar collector, or about 00 W to 40 W per square meter of solar collector being delivered as electricity under the best of conditions. These are estimates, but we need better information on the actual power delivered per square meter of a particular solar collector under the best of conditions before we can begin to estimate the amount of energy per meter squared collected over a typical year for a given location.
- Q: Just wondering if it is possible to recycle solar panels and where that would be done. If it is possible, is there a money refund in return. Or would it be better to just take the metal off and get a refund in that way? Looking for basically any answer here.
- yes they are very recyclable, and you would actually be suprised at how much you get back from them just as materials, as there are still very valuable materials in them.... Often solar shops will accept them back for at a fraction of what you paid, as they can send them back to the manufacturer who then do all the material stripping in them and recycle all the materials there. Mainly depends what type of solar panels you have.... Most probably poly-chystalline or mono-chystalline. If they are that cool blue or black psychadelic looking panel also the manufacturing make that effect is also costly so they would probably look to buying that as well.. I would ask a solar shop where it can be done as the silicon in them are still a very prescious substance..... I would definatly not throw them out or pull them apart just yet
- Q: There are places in the US where it is sunny almost all the time, like the southwest. But if we covered an area of the Sahara with solar panels, the sun exposure with the area would generate enough energy for the whole US at least. Plus, I would imagine it would be a great source of income for those countries.Why isn't this a topic under discussion or even mentioned between countries' governments/in Congress/in politicians' viewpoints?
- Good question. One of the reasons is the greed of manufacturing companies. No matter the profit margin of the product, they seem to want to charge so high a price that the break even point is ten years down the road, so the true savings are few. The cost of solar panels should have dropped way lower than they have by now. I believe that the political correctness of the product will tempt the manufacturers to keep the prices artificially high. One other answerer is right, the panels are very fragile, and damage would destroy the investment, so new inroads need to occur in technology to protect the panels from damage. Somewhere in the middle is a profit for the manufacturers, and savings for the consumer. I hope we find that middle-ground soon.
- Q: I need to write a pressuasive essay on why we should use solar panels more than we do. and convince people that their good and stuff.. if u guys could give me some good key reasons why..that would be great.
- I purchased my system because it is a good financial investment. My system will pay for itself in less than 6 years, thanks to a generous rebate from my utility. Now when the nearly 20% rate increase my city just approved goes into effect my bill will go up about $4 a month instead of $40.
- Q: i just took a trip to florida, they are cutting down anything that doesnt float and putting up buildings. Most of these cost a bundle, bill gates may pay cash for them, but most people will have many payments. Since pools, satellite dishes, and docks if near the water seem to be standard issue, why not a couple solar panels and water heater. It is florida after all, and if you are allready paying a half million or so for a house, what is another 0k gonna mean to you. Why dont they make it mandatory to include these on all new housing and condos and businesses. With that many the price would come down quickly and pay for itself long before the house is payed off and/or florida is flooded due to global warming.
- Because not only does that just make TOO much sense, it comes down a cost factor, even though, as you say, what's another couple K for saving the environment. Sad thing is, even though they *JUST* figured out that global warming (loved that news story a couple weeks ago) is caused by humans abusing the earth, Americans especially just don't care enough. Our culture is so spoiled now that we refuse to be told what we need if it's not what we want or if it will cost us $5 extra.
