Q:How does solar panel help/affect the economy?
Build okorder.com/
Q:Any companies that have solar panels?
Yes there are companies that sell solar panels, many of them specialize in solar, a simple google search with your state or city name and the word solar should get you many results. There are actually two kinds of solar panels that get installed on homes, one kind creates electricity, the other heats up water. Depending on how large a system you installed, you could have all of your electricity or hot water powered by solar, which would mean you'd use less nonrenewable resources like coal, oil, or natural gas. The other difference the solar panels would make would be in your electric or gas bill, that number would go down right away, but you'd have to wait a few years before the money you save there would cover the cost of buying the panels, the number of years depends on your state, and the size of your system. Starting in January there will be a 30% federal tax credit, that would mean savings for every installation in the US. Also a lot of states now have a rebate program, which means the system is even less expensive.
Q:What is the real cost of Solar Panels?
The cost of solar is measured in dollars per watt. That means the cost of a cell that can make one watt continuously in full sunlight. A friend of mine is starting a new job to set up a new solar cell factory and he said the present cost is $3 per watt, but that they expect to get that down to $ per watt in a few years. They can be damaged by weather, just like any regular roof. My insurance agent asked if I had solar panels, so it is a factor in insurance cost. I never heard of recycling or disposing of old panels, maybe because they are so new and last so long that not many are ready to be disposed of yet.
Q:Solar Battery System?
A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
Q:How Do solar panels work?
Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .
Q:Why don't we use solar panels?
Actually there was talk about doing some major solar installations in New Mexico and Nevada. Unfortunately our government put a temporary hold on all large scale solar installations because they feel that they might hurt the local wildlife and more studies need to be done. So, now the huge installations have been put in line and have to go through a bunch of bureaucratic nonsense. Also, just so you know, large solar installations dont generally use photovoltaics. they use concentrating mirrors and concentrate the sun on a pipe with some sort of liquid in it which boils and runs turbines.
Q:where do you get little solar panels?
There okorder.com
Q:how to make your own solar panel?
I do not have the skills to make my own solalr panles even if I want to try it. I see the answer above but cannot understand it. I bought my solar panels from OKorder and it works for me quite well.
Q:will a 5v 52watt solar panel charge four 2c dv 55ah batteries?
OK your math on the solar panel looks correct, but you are missing some critical information. What is the load on your batteries and for how long is this load being applied. Calculate the amp-hour load to see if your solar panel can recharge your batteries with the amount of sun light available. A safe engineering standard is to have twice as much capability as required. If you have a 200 amp load for 7.5 minutes, this would be a 25 amp-hour discharge and will take your solar panel over 7 hours to recharge your batteries. Your solar panel can easily charge the batteries up to full capacity with out any load on the batteries, if the batteries are 50% discharged, this will take about 32 hours. CAUTION! I am assuming that you are hooking the batteries up in a parallel connection, that will give you over 200 amps of current. You should charge each battery up to full charge before you connect them together, if they are not at the same exact voltage when you connect them together, they will self adjust so that each battery is at the same voltage level, at 55 amps this could be a very large spark. Each cell, there are six (6) cells in a 2 volt battery, should be at 2.7 to 2.2 volts DC per cell at full charge. Make sure your battery has a voltage 3.02 to 3.26 volts open circuit or no load. This should be full charge if your batteries do not have this voltage level, say one battery is at 0 volts DC, it could have a dead or shorted cell. DO NOT use this battery until you can get it to hold a 3.02 to 3.26 volt DC level.
Q:Where to get solar panels in Birmingham, AL?
Any electrical contractor could likely install them, and there are several Internet businesses that sell solar panels. You likely have no place there to get the kind of large panels you need for a house. Look at your local regulations. Your utility may not allow grid-tie, so you may have to set up an off-grid system with batteries and use separate wiring or a transfer switch. One thing a lot of people neglect is hail protection. In Birmingham, you're likely to have large hail (larger than golf ball size) every couple of years in the spring. You need to work out a way of covering them in advance of severe weather. Most panels will take up to golf-ball size hail with no problem. DK PS, I've done this myself, and have considerably more information. Email if you're interested.
