Q:Does infrared radition occur in solar panels?
Solar panels do heat up. But that's because the radiant energy from the Sun that lies within the infrared (IR) band of energy causes the material in the panels to heat up. And that's the same for any body that has the Sun shine on it. Your face, for example, will heat up while you get a nice tan on the beach. That's due to the heat producing IR radiant energy. Now if those solar panels are supposed to heat buildings etc., that heat produced in the panels when the IR strikes them will be transferred, usually by some fluid, to floors of the rooms to be heated. And as the amount of heat generated by the Sun is proportional to the area of the solar panels, bigger areas of panel will generate more heat than smaller areas. Photoelectric solar panels are another kind. Here the interest is in the visible band of radiant energy from the Sun. Heat, from IR, is still there, but it is not the product sought by PE solar panels. The visible light photons knock off loosely bound electrons from the photoelectric material (typically silicon based) and those electrons are siphoned off as current. That's where the electrical power comes from for buildings using PE solar panels to provide their own electricity.
Q:who would win in this battle?
If it was a physical battle, solar panels. It's like burning ants with a magnifying glass. Aim the solar panel at the trees and you have a forest fire.
Q:Price and energy production of solar panels?
so, you think that the best idea is to just keep focusing on oil and not to try to compete? EVERY CON I've talked to on here goes on and on about how green energy is a bad idea? yet, here's China, with a focused goal and actually making it happen... wonder how far we would be in the US without the cons fighting us every step of the way... how's that buggy whip business going cons? THAT'S what we mean when we say thanks to Republicans do you think green energy isn't going to happen? China's already doing it... we can either catch up, or give up... and give up has a big unempmloyment rate attached to it...
Q:What size and watt solar panel?
I think that typical solar panels are 2'x4' and produce something like 800-000 wh per day. (That's 0.8 - kwh per day.) More in the summer, less in the winter, if they're aimed sort of at the sun. There are newer, more expensive panels that produce more. There are also thin film panels that are less expensive, and probably more sturdy. You then have a couple choices. In a house, you'd have an expensive inverter to connect to the utility power, so you can have power at night when your panels aren't generating anything. In a trailer, you want 2-4-6 deep cycle car batteries to store the power. Then you could have an inverter to convert that power to 20v AC, so you could use normal appliances. Or, you could buy appliances that run on 2 volts DC. Maybe a combination of both. You'll need to figure out how much power you're going to use, so you know how many panels and batteries you're going to need. The calculation is easy. Figuring out how much power you need is hard. You need deep cycle batteries because you can repeatedly charge them way up and run them way down. Ordinary batteries die fairly quickly when you do that.
Q:Photodiode vs solar panels?
Yes, so are camera sensors. Except in cameras they're specially desgined to reduce noise.
Q:Solar Panels power help?
What you really need to calculate is your energy requirements, you are only stating your power requirements. Power (W) = how many watts of power are you using? Time (h) = how long are you going to use the power for? Energy requirement(Wh) = W * h take the answer to that equation and plug it into the exact same equation except substitute how much sunlight you get for h and then solve for W to find what you need in the way of a solar panel. Wattage of solar panel (W) = Energy requirement (Wh)/hour of sunlight per day (h) Now you know what wattage of solar panel you need. For the battery you use a different equation: Energy in the Battery(Wh) = Battery Voltage (V) * Current Capacity (Ah) Solving for Current Capacity: Ah = Wh / V This will tell you how big a battery you need, but you also need to be concerned about how much current it can source. For this you need to know what your peak power requirement is. Wmax = peak power requirement Max discharge current (Amax) = Wmax / Vmax Also you will need an inverter rated to Wmax as well.
Q:A Question about Solar panels?
You are missing one bit of information in order to get an answer. Watts = Volts x Amps Find out how many amps the collector can put out and you can then plug in the numbers into the equation and get your answers.

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:i am asking about the solar panels?
First of all, make sure that you are taking readings in the dark (with the solar panel indoors and covered). 0.433 is a reasonable forward voltage for a Schottky diode. Ideally, it diode should read open one way (possibly OL for your meter), and 0.4 the other way. If it's reading OL both ways, the diode is bad. You can either unsolder it or cut it out and verify that it is bad.
