Conclusion
The purpose of this experiment was to see in what temperature solar panels operated the best in. Major findings included the fact that solar panels produced more electricity when surrounded by colder air, contradicting the hypothesis of when the temperature was warmer, more electricity would be generated. Two examples to show this are when it was 80 degrees, on reading was 6.52 volts, while the colder temperature reading of 20 degrees showed 7.36 volts generated. The reason that the variables of temperature and the electricity generated were chosen was to see in which temperature conditions would have solar panels operating the best in.
A comparison from the expectations was that solar panels generated more electricity when in colder air, as opposed to the hypothesis in which it was predicted that it would be better in warmer air. Also, the reason behind the hypothesis, which was that photons would move faster in warmer temperatures, and generated more electricity, was proven false. An explanation is that while photons are excited, the electrons are excited as well, making the power difference very low, so less electricity is generated. Electricity is generated when the power from the photons are transferred to the electrons, so when it is warmer, less energy is transferred.
Two possible errors in this experiment could have been temperature differences and different amounts of sunlight. Temperatures might have differed during the experiments, causing different measurements of voltage than the intended. This might have been the case for the 80 degree measurement, trial 6, as it differed from the mean of 6.51 volts. The measurement was actually 6.25 volts. The difference is notably higher than the standard deviation, which was 0.18 volts. The varying amounts of sunlight would have affected the amount of sunlight collected by the solar panels and affected them by giving less on particular measurements. In order to improve this experiment, the constants had to remain untouched. In order to accomplish no temperature differences, it would have to be so no heat escaped or got in. So, the fish tank in which the experiment was conducted in would have to be completely sealed. Also, if the experiment was done with more trials, it would be more reliable. As for the sunlight, next time it would be better to do all of the experiment while it was completely confirmed that all solar panels were receiving the same amount of sunlight.
It is necessary to perform this experiment again because if it was performed again, more reliable results would be found. Also, performing the experiment again would be an opportunity to make sure there are no errors and get completely accurate results.. This experiment can be taken to the next level by using bigger solar panels, and having more than one independent variable.
