Will Solar panel temperature increase when solar array power shunted off?

Yes, it will, but only a small amount. Solar panels today only harness about 11 percent of the suns power, the other 89 percent heat up the panel even while it is running a load someplace else. On a good sunny day with a temperature of 75 degrees, you panel will heat to 140 to 150 degrees with a load on, and maybe 160 with the load off. As a side note, solar panels are more efficient when it is cold out, as long as you have good sun. Most of the manufacturers require you to upgauge your wiring when you have daytime temps below 40 degrees F, and again below 0 degrees F to accomodate this higher output. On very cold days in the northern tier, you can get as much as 1.5 times the rated power out of a solar panel. Take care, Rudy

What is a solar cell?
A solar cell is an electronic device that converts sunlight into electricity. An array of them is called a solar panel.
What is the best chemical to sterilize under a solar array?
Palladium.
How can the electricity from my solar array use the same overhead wire that feed my home without causing an explosion or trip somewhere?
A solar array produces DC electric power so before it is connected to your power supply it has to be converted to AC. That is the function of the equipment that connects the panels to the power supply. - - - - - Your solar array needs a device called an "automatic transfer switch." This switches the circuits you're running off the solar array from the grid to the solar when the sun is bright enough to power those things.
How much solar panel surface area is required to generate 1500kW at a panel efficiency of 30 percent?
You can size your solar array in just two easy steps! (Well, okay, there's a little research involved, too.) To estimate the size of your solar array, you'll need to know: # The number of Watt-hours (Wh) you plan to produce in one day. # The insolation value at your location. I have found this website to offer the easiest way to find out How Many Solar Panels do you need in your Solar Array?http://howto.altestore.com/Library-Articles/Solar-Electric-Power-or-PV-Systems/How-Many-Solar-Panels-do-you-need-in-your-Solar-Array/a88/
Do solar cells produce a lot of energy?
Each one, no. But an array has multiple cells.
Is a solar powered car faster than a battery powered car?
Solar powered cars are battery powered cars. The solar array is charging the batteries. So there is no real difference.
What is photovoltaic array?
It is a group of photovoltaic modules which are linked and are made of several interconnected solar cells.
What is the purpose of a linear array in descriptive essay writing?
The purpose of using a linear array in descriptive essay writing is to present information in a logical and organized manner. It helps to arrange details spatially, showing relationships between elements and helping readers visualize the topic more clearly. It allows for a structured progression of ideas and enhances the coherence of the essay.
Can you use a light bulb for solar power?
If you mean could you use the light from a bulb to energize a solar array or photovoltaic cell, the answer is yes. However the energy to run the bulb would exceed the energy produced by the array so you would have a net loss of energy in such a system.
What variables are required to calculate the amount of output solar power from a solar array?
You would need to know the rated wattage of the solar array, the efficiency of the related components, the location of the array, the angle of the array, and the direction it faces. If you have all of this and you are in the US, Google 'PV Watts' plus the name of the state you are in. The 1st result should be the Pvwatts website for your state and there will be a map of you state there for you. Click on the nearest town, enter the information above, and hit calculate. The program will give you the monthly and annually produced kilowatt hours for the system. Example below is PV watts Colorado.
Do scientific calculators solar or do they require batteries?
Most scientific calculators that are sold today have plenty of solar and battery powered sources, so you have a wide array of choices.
How do you figure out how big of a solar cell you need for a job?
You look at the job you need to do, ie, how many volts and amps, or volts and watts, that you need. Then you look in the catalogs for a solar cell or solar cell array to produce that much power.
