- Q:Can someone tell me the average savings you get PER solar panel installed? I do not have the money to invest in a bunch of them at once, so I am forced to buy one at a time, when I have the money. So how much can I expect to save after I buy the first one?
- No matter what or how you do it it is best to get off coal and nukes. So it cost a little bit of money you are buying 30 years of electric. How much will you spend adding in cost of living increases over the next 30 years? Solar really is pretty cheap if you take the time to do the long term math. If you use your cost at to days rates it does seem like a lot. But if you do the math like in real life with 3.5% compounded cost of living increases per year and 6.5% fuel increases per year. Well, you pay a lot more renting power. One other thing to think about and Al Gore keeps pointing it out is, Will your off spring be alive in 50 years from now if you don't buy the solar panel? Kind of like not going to the doctor because you can't afford the bill. Well I would rather owe a bill to a doctor that I will have trouble paying then not be alive at all to try. If you don't have the money to jump in and go full blown Green you should buy a starter system. You can get a system that can be expanded to 3000 watts (enough to power an energy efficient home). Would cost you about $8000 USD to get started and then you could add three solar modules at a time till you get it up to the 3000 watt max. And even have backup power. Or you could just buy a 000 watt system for about the same price and just add 3 of them over the years. There are many ways to get started. The deal is everyone needs to get started even if it is a small system. If all 50 million homes in the USA would install a small 000 watt system with 4 hours of sun light a day. We would provide (000 watts times 4 hours times 365 days times 50 million homes) 29,000,000,000,000 watts not from coal or nuke plants per year. I wonder if that would help?
- Q:Can solar panels be installed on commercial buildings?
- Yes, solar panels can be installed on commercial buildings. In fact, many businesses and organizations are increasingly opting for solar panel installations to generate clean and renewable energy, reduce energy costs, and demonstrate their commitment to sustainability.
- Q:My washer is 20 volts 60 gz,9.6 amps. The solar panels I am looking at are: Sharp ND-208U Solar Panels (208 Watt) List Price $,479.99 Only $,049.99 Sharp Solar Panels (208 Watt) List Price $,352.99 Only $,040.99 If I buy that will it be enough to run my washer?
- The solar panels have a 2 volt DC output.You would have to get an inverter and a small battery bank to run the washer.
- Q:In nature, green leaves collect light and produce energy. Is this what they copied to make solar panels? If not how hard would it be to make artificial leaves that would power our homes?
- No, although they both use the capture of energy from electrons excited to a higher state by sunlight, plants use enzymes (mostly chlorophyll) packed in chloroplasts; solar panels still largely use silicon. There are some companies exploring the use of a plant enzyme-based process since it's so much more efficient. The farthest they've gotten is using organic nanocrystal pigments instead of silicon crystals.
- Q:So you know how the bigger the surface area exposed to the heat radiation means the quicker it'll heat up.Is this what happens with solar panels, they have a large surface area exposing to the sun, so they can get more heat?
- Solar panels do heat up. But that's because the radiant energy from the Sun that lies within the infrared (IR) band of energy causes the material in the panels to heat up. And that's the same for any body that has the Sun shine on it. Your face, for example, will heat up while you get a nice tan on the beach. That's due to the heat producing IR radiant energy. Now if those solar panels are supposed to heat buildings etc., that heat produced in the panels when the IR strikes them will be transferred, usually by some fluid, to floors of the rooms to be heated. And as the amount of heat generated by the Sun is proportional to the area of the solar panels, bigger areas of panel will generate more heat than smaller areas. Photoelectric solar panels are another kind. Here the interest is in the visible band of radiant energy from the Sun. Heat, from IR, is still there, but it is not the product sought by PE solar panels. The visible light photons knock off loosely bound electrons from the photoelectric material (typically silicon based) and those electrons are siphoned off as current. That's where the electrical power comes from for buildings using PE solar panels to provide their own electricity.
- Q:Are there any health risks associated with solar panels?
- There are no direct health risks associated with solar panels. However, improper installation or maintenance may pose electrical hazards, and exposure to high temperatures or falling from heights during installation can lead to accidents. Additionally, some solar panels contain small amounts of hazardous materials, but they are tightly sealed and the risk of exposure is minimal. Overall, when installed and maintained correctly, solar panels are safe and have numerous environmental and health benefits.
- Q:about solar panel
- The answer depends upon the type of solar energy captured . Photovoltaic Solar Panels convert the energy into electricity. This electricity is ran throughout the building via wires. Thermal Solar Panels typically capture the energy in the form of heat. The hot water is circulated through the building in water pipes.
- Q:How much candle lights is required to operate a 205 watt solar panel?
- That's hard to tell. A solar panel produces somewhere between 7 and 0W per square foot under sunlight exposure. You should calculate the light intensity of sunlight, and then calculate the light intensity of a candle (You'll have to look that up in some physics book or the internet) and then just multiply the number of candles until you match the intensity of sunlight. Realistically, you would need so many candles that you wouldn't be able to fit them in front of the solar panels, assuming you don't end up with a huge fireball.
- Q:How much energy can solar panels generate?
- The amount of energy solar panels can generate depends on various factors such as the size and efficiency of the panels, the location and orientation of the installation, and the amount of sunlight available. On average, a typical solar panel can generate about 250 to 400 watts per hour. However, larger solar installations or those with higher efficiency panels can generate several kilowatts or even megawatts of energy, which is enough to power homes, businesses, or even entire cities.
- Q:why don't we take a cue from mother nature and make our soar panels like trees? thousands of leaves or needle (like a pine tree) instead of one big flat panel? I mean it seems to work pretty good for all the plants i see why would it not work for us. It would be aesthetically pleasing and with the right engineering wouldn't it make them not have to worry about tracking the sun? i already have some ideas about the process of making them just no available labratory.
- Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
