Q:Are solar panels only effective in places where there is an abundance of sunlight?
Solar panels are *more* effective in places with abundant sunlight, but can be used anywhere that there is light. The problem is an economic one. Solar panels are expensive and can only produce so many watts per square meter. If you have less sunlight, you'll need more panels to get the same amount of power. Germany has a relatively high latitude, and are reported to make extensive use of solar panels (funny, I spent 2 weeks there last month and saw very few panels). The reason for their use of the panels is that their government offsets the cost of installing them through subsidies. Other governments have similar programs.
Q:How would you build a Solar Panel that can convert Sunlight to Energy, just being on your house roof?

Q:how do I become a solar panel contractor?
You okorder.com
Q:Is there anyone trying to create a cheaper and more efficient solar panel?
The cheapest will be solar paint where you lay down some wires and paint the panel on. Solar roof tiles are also coming along but each tile has to be wired in. Currently the target is $ a watt. The efficiencies of these panels are very low but if the cost is low enough then the efficiencies won't matter. Keep in mind that even fossil fuel is solar power, just solar power captured by photosynthesis millions of years ago, and photosynthesis has a maximum theoretical efficiency of 6.6% with most plants achieving less than % efficiency so even an inefficient solar paint already outstrips our current energy sources in terms of efficiencies. The real problem is the business model. With solar energy you can sell the panels upfront but then what do you do for an income whereas with fossil fuels, you sell every kwh and bill each month.
Q:Why don't we design a wind-turbine with solar-panels on it?
Hmm, okorder.com/.. Glad to see you thinking though, keep it up! Knowledge is power the more knowledge you gain about a variety of subjects processes the more you truly understand the truth depth of that statement.
Q:Cost of a solar panel?
That's more like a bare laminate, and will not be durable, but will get you a legitimate $/watt. Also understand that if a manufacturer has a cost of $/watt, that means the panel will cost more by the time you buy it. It has to be shipped, stocked somewhere, and the retailer has to make a profit. $560 is high for a 20-watt panel today. Whoever is selling at that price will not sell many, or will sell only to those who aren't shopping around.
Q:Cars with Solar Panels?
Sailboats typically run on wind; hence, Sailboat. I haven't read your article on it though; but, I would think that the solar power would be for the battery powered stuff and possibly a little motor for it. For a car... There are competitions, right now for solar cars. Only they are very light and don't really go that fast. The panels tend to be large and weight a bit more than one would think. I don't understand why they can't simply make a car generate power simply by the rotation of the wheels itself. They could take a hybrid, take out the gasoline portion and it would simply recharge the batteries by the friction of the turning wheels.
Q:What is the working principle of solar panels?
the material is easy to industrial production and material performance and stability.
Q:How would you connect a solar panel to a fan?
Panels are rated nominally, and you can look at your fan to see what the ratings for the fam are to determine sizing of the panel. Current multiplied by the volts (rated) gives you the wattage of the motor- just use this as a guide for sizing the panel. You do want a little more power from the panel than the motor draws for purposes of starting the motor and for having the fan operate at lower sun angles as well. You can add a battery if you chose, but it is not a requirement. Just treat the leads of the panel like those of a battery red (+) and black (-) just connect those to the fan, if you match color for color, no problem. If the markings are not present and no wires are on the fan, try it one way, if it is the wrong way- reverse them. AC operated fans will require an inverter to convert the DC to AC. These draw a certain amount of power as well. In general the same rules of thumb apply. It is just easier though to stick with a DC motor.
Q:How big of a solar panel system would I need to get ?
First find out from your electric company whether they allow grid tie systems. IF so then they can help you figure out what you need.
