Q:Could solar panels contribute to global warming?
Claire's argument doesn't make much sense to me either. First; Claire is talking about the second law ('you can only lose or break even'), not the third law ('you can't get to absolute zero'). Easily confused, but not that important! Putting a solar panel down _can_ increase the heat absorbed by Earth. Everything has an 'albedo' (the proportion of incoming light it reflects), and Earth's average albedo is about 0.3 (ie 30% of incoming light is reflected, most of which leaves the atmosphere straight away). By putting a 0.05 albedo solar panel down on a 0.3 albedo surface, you increase the amount of sunlight that is absorbed by Earth and therefore contribute to warming. This heat is re-radiated at the Earth's temperature, in the right wavelength range to be absorbed by greenhouse gases too. If you put a panel down on equatorial ocean, or a black roof, however, there is pretty much no effect (since the albedo change is small). Also, the heating effect only lasts as long as the panel is there. Most panels are estimated to last 50 years, meanwhile CO2 has a mean lifetime of 00+ years. I did some maths and found that the 00 year averaged change in radiative forcing for solar panels was negative compared to the UK electric grid, because the reduction in CO2 emissions has a larger effect than the change in albedo. If I have spare time tomorrow I'll redo the calculations and share them. The albedo change has to be considered though!
Q:What does solar panel power?
The first thing to understand is that there is nothing complex about a solar panel. It is nothing more than a collection of solar or PV cells on a board that is fitted to the most appropriate part of your home, generally on the roof. There are guides out there that teach you how to build a solar panel and a windmill for just $50, and it’s very easy to make. Best of all, you can save 70% or more on your energy bill, adding up to thousands of dollars each year in savings. I reviewed both free guides and paid guides and have come up with our top to Build your own solar panels.
Q:With everyone thinking green...how green are solar panels?
Most of the early panels were not very green. They were not very efficient and did not have a real long life span. The newer one are getting much better and there are several companies have cropped up that rebuild many different kinds of panels. Some of these newer panels have a life span in excess of 30 years and are much easier to maintain. The biggest problem with solar systems is that they are not kept clean and loose efficiency. If interested in setting up a system for your self, Please be very careful who you have do the work and what system you buy. There are many companies out there that are just trying to make a quick buck at your expense.
Q:Cost and energy generated by solar panel?
A little more than 0 watts per square foot, so that size panel would generate 250 watts under ideal conditions, which is noon on a sunny but not too hot day, near the equator. That's about /3 horsepower, or the same power as a man working hard. That is larger than needed to keep the battery of the car charged, unless you plan to run a laptop or something off it at night. The power is also too small to power the car for driving. If it's an electric car, you could get maybe another 2 miles per day out of the car, again, under ideal conditions. An RV store might have an idea of how much installation would cost. They would be accustomed to solar panels for RV's, but probably not small cars. A panel of that size would cost perhaps $500-800 just for the panel.
Q:Connect Power Outlet to Solar Panel?
You will need at least 500 W of solar panels (probably more to cope with cloudy days), and a DC to AC inverter. Since you're going to 8pm you *may* want a battery bank system too for those shorter winter days.
Q:Is photovoltaic array another name for solar panels?
Photolvoltaic arry is the more technical name and the more accurate name for solar panels. Photo indicates light and voltaic indicates a voltage is produced.. Array is just a layout of these little light sensitive electricity generating panels. Actually Solar only idicates the SUN and not light in itself..
Q:how much do commercial solar panels cost?

Q:Solar panels........................?
If your purchasing solar panels for a building or colony where a few families live together, the cost of the panels can be distributed or shared. And loan and electricity bill wont be the same. Loan is a one time transaction while electricity bill you have to pay monthly and everytime. You dont have to buy solar panels every month lol. So its a better option to spend on solar panels although it maybe a big amount, rather than paying high bills every month....
Q:How to make 2V 4.5A solar panel from solar cells?
To increase current, you connect the cells in parallel. But I think you really mean you need 4.5 watts rather than 4.5 amps of current. For an RC car, 4.5 amps would be huge, literally a regular car battery. So I think you mean you need a 2v, 4.5w panel. That would make more sense for an RC car battery. I went on OKorder and bought a 2v, 5 watt panel for about $30.
Q:What do you know about solar panels?
If you want to see one up close find a solar powered calculator or a solar powered garden light at your local supermarket, they all have solar panels on them. The bigger the panel the more power, that's why the panels on the ISS are as big as a garden, they produce thousands of watts
