Q:Are you a solar panel specialist?
Yes and No. I'm hardly a 'genius' or 'specialist' but I have built a couple solar panels on my own. They're actually pretty easy to construct and you can find all of the materials at your local hardware store. Each panel cost me about $60 to make. Solar technology is jumping by leaps and bounds, becoming more and more efficient :photo voltaic cells, for example. Solar energy is a viable energy source, that's for certain.
Q:How long does it take to charge a 2v deep cycle battery with a 0 watt solar panel?
0 Watt Solar Panel
Q:do solar panels have to be in direct sunlight?
As above, but also make sure the panels you use will still produce if partially shaded. Some older panels will quit producing if you so much as put your hand over a small portion of it. Newer ones don't do this but are more expensive. As you may need more panel area to produce enough energy to fill a battery (if that is how you go) make sure you have the room/roof area for additional panels.
Q:Question about using solar panels......?
I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.

Q:How can I be part of the solar panel industry?
Manufacturing your own electrical solar panels is out of the question. They are built much like computer chips and setting up a plant to do this would cost millions of dollars. You could become a solar system installer. These businesses install solar systems on homes and are paid for this service. You will need a significant amount of technical training to do this though, I would guess at least two years (the last thing you would want to do is damage someones home or design a system that is dangerous). I would suggest that you go into business making energy improvements to homes that do not involve solar energy. Most people can get the best value for their money by improving the air tightness of their homes (several tubes of well placed caulk). Other things you could offer would be the upgrading of door, Windows and electrical box seals. Insulation jackets around hot water heaters is also something a small firm could offer home owners. Other energy improvement are also possible and you could offer a whole shopping list of improvements to a customer. Good luck
Q:Solar Panels?
Well, the best way to buy solar panels is to shop by watts. Solar panels come in a wide variety of watts, from to over 200. However, the more watts a panel has, the more it costs. I would suggest getting small things first, and gradually converting to solar power so as to help the environment and save money. If you have an outdoor pool, buy a solar collector to heat it. It will extend your swimming season and once you hook it up, you won't have to worry about it. (My cousins have this on their pool.) Also, there are solar cell phone chargers available for purchase, you could get one of those. As for your house, you would need several solar panels and a converter to be able to power your whole house on solar energy.
Q:Im looking at getting solar panels.
Your problem will be the days that are too cloudy, rainy, (snowy won't apply since you will need A/C during summertimes) and the night hours when there is no sunlight. A battery might be okay for a while but if you have to have a good one. Is there is a battery that can run an air conditioner for long without crapping out! I don't think you will ever recoup your investment.
Q:how much would it cost to generate MW electricity by solar panels??? and how much land it requires ?
I like Rouse's answer, which points to the factors to consider. If you are in India, adjust the inputs to match your local situation. For example, the peak equivalent sun-hours per day might be twice his figure, leading to half the cost. You might find panels that have a 25-year life, reducing the cost per kWh by another 20%. Land and/or labor may be cheaper, also reducing the cost.
Q:How does a solar panel work?
The term solar panel is best applied to a flat solar thermal collector, such as a solar hot water or air panel used to heat water, air, or otherwise collect solar thermal energy. But 'solar panel' may also refer to a photovoltaic module which is an assembly of solar cells used to generate electricity. In all cases, the panels are typically flat, and are available in various heights and widths.
