Does Temperature Affect the Energy Levels of Your Homes Solar Panels?

Your Homes Solar Panels Efficiency

The temperatures of solar panels affect the output of power generated by solar energy, although temperature does not affect the amount of solar energy collected by your solar panels. The hotter the solar panels get the les efficient they are at producing power from the same amount of sunlight. The energy solar panels use from the sun is light energy not heat energy.

The cooler the solar panels are, the more efficient they are. Temperature reduces productive levels of solar cells and their efficiency of changing solar energy, sunlight, into power, electricity. Simply put, the chemical changes going on within the solar cells are much more effective and productive at cool temperatures rather than at hotter temperatures.

It does sound ironic, when most people consider solar panels effective in hot, dessert temperatures. The sun beating down on solar panels, people think, they are making all kinds of electricity. This truthfully is not the case. The efficiency of solar panels at producing power makes them an optimal choice, especially in the dessert. They are a plausible choice in Alaska too. Although, the number of days the solar panels are efficient at producing power in the dessert outnumber the number of days they are efficient in Alaska.

In conclusion, the answer is yes it does. Light being of a large number of photons, the particles that carry the energy linked to light, hits the solar cells and bump right into an electron. Bumping into the electron means the photons pass the energy they carried to the electron. When they pass the energy they were carrying, the electron changes into a higher state of energy. Solar Panels come designed to extract the high-energy electron and run it through the circuit, using the energy form this electron. Often, the high-energy electron bumps into other atoms before extraction from the functions of the solar cells. Then loses its extra energy meant for the power, and the energy turns into heat instead of electricity. The vibration from the atoms and molecules is heat. If solar panels reach higher temperatures, atoms are vibrating faster, and then the electron cannot get out without bumping by these atoms. The output power drops when solar energy cells heat up, due to the lost energy before it escapes the solar cell.
