Hi Everyone!
I have three different questions to ask you all.
I am doing an experiment on Solar Panels.
So the first question i have to you is whether heat is a factor that plays a part in the amount of power a solar panel can produce?
The second question is why is it that when i connect the solar panel to a load, the voltage drops drastically. Like from 19.66 drop to 13.45. Is there an explanation for this?
The last question i have for you all is why does a solar panel produce more energy when it is tilted towards the sun then when it is laying on the floor flat.
Please remember to answer all the questions if you can. Thank You.
Sorry, i should make my question clearer.
What i meant to say was that when i connect the solar panel in an open circuit (meaning measure the voltage by just connecting the voltmeter to the solar panel). The resulting voltage is much higher than the resulting voltage when i connect it in a close loop (measure voltage and current, where a rheostat, voltmeter, ammeter and solar panel is connected to each other).
So i want to know why there is a difference in the voltages.
Dear friend first up all the solar Panel is not directly connected with the heat it absorbs from sun. It is the ultra violet rays produces the electricity. I am having three panels of different size in my house. These Panel capacity is given by its watts and volt. The product of volt X amps is equal to watts. Even during raining without affecting the light I get solar energy.
1.Heat is not the factor. It is the ultra violet rays produces the electricity.
2. Normally at no load the voltage will be higher than what they have mentioned.The voltage will be correct only when you connect the Panel into its proper capacity load.
3.Tilting effect absorbs more ultra violet rays.

Because hot water rises and cold water sinks so the hot water runs out a pipe at the the top of the hot water system while more cold water is feed in the bottom. This is because of convection currents.

they’re tilted at a special angle because it’s at that point that it can pick up the most heat because of the time of day.
sorry. it’s a bit hard to explain.
try this. at exactly twelve o’clock you’d have it facing flat on the ground to get the most light from the sun.
but, this might not be the time of day when the sun produces the most heat, so they set it at the time when it’s facing the direction that produces the most heat.
sorry if you didn’t get that.

Good questions, and they need expert answers - wait until you hear from an engineer, or, better yet do some research on the Internet.
The only one I can answer is about the tilt angle. Two things: when the panel is tilted you get more light reflected off the surface, so you are losing some energy that way. Also, when the panel is tilted it is intersecting less sunlight - look at the shadow of the panel when it is tilted, it is smaller, which means that you are not capturing as much light.
