GENERAL INFORMATION

The installation of PV modules requires a great degree of skill and should only be performed by a qualified licensed professional, including licensed contractors and licensed electricians. Please be aware that there is a serious risk of various types of injury occurring during the installation including the risk of electric shock. All CUSTOMER modules are equipped with a permanently attached junction terminal box that will accept variety of wiring applications or with a special cable assembly for ease of installation, and they do not require assembly.

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:where to face solar panels?
Not compass south, but solar south. It's easy to find. Google Find Solar south and you can get directions. Even better are trackers, that will let your panels track the sun all day.
Q:how to power a 400 watt heater with solar panels and batteries?
You could do that, but it would be an expensive way to go. If what you really want is heat, consider heating water directly with conventional solar water heaters, and storing it in a large, insulated tank. You can then circulate the water through a conventional radiator at night.
Q:time till a solar panel pays itself off?
the Department of Energy has a ' solar hours calculator for locations around the US factoring in hours of sunlight.....the other factor is how perpendicular to the sun the panel is.....as a wild guess I'd say Buffalo's solar hours factor is about 3....which means as an average over 365 days you get 3 hours a day of maximum ( 50 watts ) output. So 3 x 50 x 365 = 64.25 kWh a year. At, say, 5 cents a kWh, you're making $24.63 a year worth of electricity. See why the houses of upstate New York..let alone Ohio or Virginia or Georgia.....aren''t covered in panels?
Q:where could i buy a cheap and low cost solar panel regulator?
Solar cells shouldn't need a voltage regulator for simple projects like driving motors or powering CMOS electronic circuits. I would need to know a little more on your goals for the project to help. However, I will put a few links that may be helpful to solar cells and some voltage regulators. The first link is general solar cell info and includes manufacturer lists at the end. The second is a link to educational solar cell kits and cells that may be useful for you. The last one is Digi-Key which is good for finding components to make your own voltage regulator. Hope this helps with your project!!
Q:can you hand make a solar panel?

Q:Finding the output of a solar panel?
You need full sunshine from the sun, or a lamp that will give a light spectrum similar to the sun, a volt meter, Milli-amp meter, and a variable resistor of 0 to 000 ohms. The voltmeter test leads go across the solar cell leads. The amp meter leads will be in series with the solar cell. Let's say, positive lead of the solar cell to the the positive lead of the amp meter, the negative lead of the amp meter to one terminal of the variable resistor, and the wiper terminal of the variable resistor to the negative lead of the solar cell. Slowly decrease the value of the resistor until the voltage from the solar cell just begins to drop. Take note of the amp meter reading. This is about the high end range of the solar cell. You might want to begin with a micro-amp meter for the current meter.
Q:can I run a desktop computer with a solar panel?
Any source capable of providing 300W should work but I'd recommend you get a UPS if you are relying on either of the two power sources you've mentioned.
Q:Can a solar panel be used as a NiCd cordless tool battery charger?
Two of those solar panels connected in series will easily charge a 8V battery. I would not even be concerned about over voltage the solar cells will have plenty of internal resistance.
