Q:Can someone tell me about solar panels for homes?
I okorder.com Hope this helps.
Q:What does solar panel output refer to?
Solar panels are rated under standard test conditions (STC), a certain amount of light at a certain distance, at a certain temperature, etc. A kW, or kilo watt, is 000 watts. So for the amount of time that the sun meets those conditions, the rate of output is 500 watts. An average location has an average of 5 sun hours a day, the total time that you produce the rated output. Watts is a rate, like miles per hour (mph), how fast it is going. Watt hours, or kilo watt hours (kwh) is a quantity, like miles. So if you drive 50 mph for 5 hours, you went 250 miles (50 mph x 5 hours). If you produce .5kw for 5 hours, you have the potential to produce 7.5kwh a day. Multiply that by 30 days in a month, you get 225kwh a month. In reality you will lose about 30% of the rated power from less than ideal weather, system losses, etc., so it's more like 50kwh a month. You can look at your electric bill to see how many kwh you use a month, maybe around 000kwh, and see what percentage of your usage a system like that can power.
Q:Solar Energy Panels, a good idea?
The panels are relatively easy to install. The batteries and the inverter tend to be heavy and you will need many people or mechanical assistance. You are talking about high current DC thus if you touch the wrong wires it's CC (Cancel Christmas - Rescue Squad Term). You also also dealing with lead acid batteries so they need to be well ventilated or we have another CC situation. Should you have a short, the batteries will overheat and explode projecting sulfuric acid... And the best part is when all is said and done, you are only paying twice to three times the cost for the electric over the life of the system as compared to buying the electric from the power company.
Q:how do solar panels work?
Solar panels is built of the solar cells in it..these cells are typically made of paper thick Silicon or Germanium metal (called semiconductors).When light falls on these solar cells the energy recieved from the light (photons)is used to emit electrons due to the nature of semiconductor material. These electrons being of negative charge are attracted by opposite positive charges or there is current flow from cathode to anode on these cells.This small electric charge generated is used to store in the battery connected...more the number of solar cells more the electricity generated .
Q:Solar panel for your home?
it all depends on how much electricity you use for heating/cooling and cooking.......if you just need lights, TVs etc then you could get away with about $5-8,000 US for a system depending on how far north you live.....to go completely off the grid is near $25,000 by the time batteries and inverters and all of that is figured in....
Q:Why are solar panels so expensive?
The only way I know of is to invest the money in the stock market. Most savings accounts only pay 3% intrest. While stocks float and if you don't know what you are doing you will never make as much money as you could save on your electric bill. Then the fact that you have to pay the electric bill out of the money. In the end you rented electric and can never get your money back. You can always sell the solar electric system and get your money back plus a profit. Not many people live in the same house even 20 years so it will sell. Toss the coin. It is what ever is best for you.
Q:i want to light up a building using solar panel what do i need?
The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
Q:how to store energy from solar panels?
On a battery obviously, otherwise there would be no point in installing panels to Generate Energy from Home.
Q:solar panel help needed ?
One square meter of solar panels can produce up to 50 watts of maintenance-free power for up to thirty years. The most common solar panels are for 2 V applications. For sq meter: I = P/V = 50/2 = 2.5 A A single solar cell always produces a voltage of approximately 0.5 volts, regardless of its size. For higher voltages, you have to connect individual cells in series to add their voltages. The larger the solar cell, the greater the current will be. You can also connect cells in parallel to increase current. Hope this helps!
Q:Opinions on Solar Panels?
Bing solar power in Germany. Solar power has an option of assisting in removing some of the burden during daylight, from power generation plants. Anything is a help. Plus they will continue to do it forever (at least a lifetime). But they are not the total answer. Like wind, limited to certain areas. Wave generation is another solution, but still limited to coastal areas. The current design of most supply grids does not allow transportation of power long distances. You want a real eye opener, Bing transportation line looses power grid and see how much energy is wasted, and the amount of carbon put into the air for these losses.
