Q:Solar panel angle question..?
2.20 approximatey (2 /4 -- ish) X = (tan7)(8/tan45)
Q:Does anyone know a good company to buy solar panels from?
Guide okorder.com/
Q:Solar Panel Manufacturing?
No okorder.com 3) Figure out how much labor and material cost would go into each panel. Would you locate in the US? It's hard to beat the big players in China, in this commodity market. It would be like having a small company to make laptops, and trying to beat HP, Dell,and Lenovo.
Q:Research Paper on Solar Panels?
I'm a big fan of solar panels, and we even have an array on our house, but I would have a hard time supporting the thesis that solar panels are the best way to go green. Conservation and efficiency are. Using less is better than making more. If someone has the money for panels, but their house is poorly insulated, their money would be better spent on insulation. Pretty much anyone in the solar industry would agree. And solar hot water makes sense over a much wider geographical range than solar electric.
Q:what is solar panel? full description needed?
Solar panels are devices that convert light into electricity. They are called solar panels because most of the time, the most powerful source of light available is the Sun, called Sol by astronomers. Some scientists call them photovoltaics which means, basically, light-electricity. A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful. The more light that hits a cell, the more electricity it produces, so spacecraft are usually designed with solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going. DS's solar cells are even more efficient than regular solar panels made for satellites because they use solar concentrators.

Q:what are bad things about solar panels?
If it is cloudy out, the solar panels won't pick up any sun, therefore they won't work. Also, not all areas actually get a lot of sun, so solar panels would only be useful in certain places.
Q:Why do solar panels stop working?
They really don't stop working unless there is some sort of manufacturers deficiency, where a connecting tab(wire) is broken. Generally their output just decreases over the years. There are plenty of solar panels over 40 years old still producing electricity, which is 0 years past the typical 30 year manufacturers waranty.
Q:How many Solar panels?
Quite a bit to run 480 volts @ 50 amps. Ohms law will give you the basic level your looking for but also you need to consider power storage ... Conversions .... Start up power vs running power levels ... it can be done but this is a bigger system then what I need so I cant just give you an number your panels will be rated in wattage and amperage you then take that power and put it in storage (battery) to inverter system (mine is 20 volt) you will need to have a 480 inverter for your power level. good luck hope I was of some help.
