Abstract- The use of solar energy as a strategy to reduce global warming's devastating consequences is a promising area of research. Due to solar energy's low greenhouse gas emission rate, it has the potential to replace a large number of traditional energy sources. The goal of this research is to increase the output of energy generated by Photovoltaic cells by increasing the amount of solar radiation and sunshine they receive via the use of mirrors. The result is increased energy production from a concentrated area of solar panels. The study's goals are to (1) assess if simplified mirror methods may enhance solar cell performance, (2) identify which features of solar cells can be enhanced by such approaches, and (3) verify that the solar cells' performance has been enhanced as a consequence of the enhancements. Using flat reflectors, more sunlight may be focused onto the solar panel's surface. Parabolic reflectors might potentially be used in this situation, but they are more expensive to make than flat reflectors, thus that route wasn't taken. This kind of mirror can only focus sunlight in a certain direction onto a smaller area if placed in just the right spot. Because of this, the solar panel's temperature might rise, requiring a cooling system. Considering that radiation levels are greatest towards the middle of the day, this is to be expected.
(Emetere, Akinyemi and Edeghe., 2016). Solar panels are commonplace in areas where it would be impractical to build transmission and distribution lines because they generate power for local inhabitants. Researchers Richard Evans Day Adams discovered that selenium exposed to light generated electricity, although at low efficiency, in 1876. Following this, researchers dived deeply into investigating and testing methods to improve solar cells' efficiency. They negotiated a reduction in the exorbitant electricity prices to where they are now, only a few cents per unit. It is expected that in the and William Grylls future, thanks to innovations like titanium oxide (TiO2) cells, which have a peak efficiency of 32% in the lab and an average efficiency of 15-20%, the cost would drop, making it competitive with other power generating sources (Jahagirdar, Khot and Joshi., 2019). Unfortunately, the price of converting solar energy into usable form is still far higher than the price of electricity produced by burning fossil fuels. The sun's rays are a valuable resource, and it is important to capture as much of them as possible.
2. Discussion Enhancing Solar Panel Performance with an Easy-toImplement Cooling Scheme
Keywords: Solar panel, battery, mirror technique, PV
The study that was carried out by Jahagirdar, Khot, and Joshi came to the conclusion that the production of solar systems and their overall performance are reliant on the amount of natural sunshine that is available. Despite this, temperature also plays an essential part in the efficiency of these systems and is one of the most critical impacts. It is also one of the most influential factors. The goal of this study was to determine how the temperature of solar panels may be lowered while they are functioning by applying a cooling mechanism, both on the surfaces of the panels and on the panels themselves. This was done in order to improve the efficiency of solar energy production (Jahagirdar, Khot and Joshi. 2019). During the course of the tests that were performed, it was discovered that the solar photovoltaic system generates different levels of output power, output voltage, current, and efficiency depending on whether or not it is paired with a cooling system. This was discovered as a result of the findings that the solar photovoltaic system produces

1. Introduction Solar energy is clean, renewable, and available all except in the coldest months of the year. It is estimated that in a single hour, the Earth gets enough solar energy to provide the whole world with energy for an entire year. Similarly impressive is solar energy's ability to mitigate global warming. Solar power has the potential to substitute many conventional energy sources due to its low carbon impact. Carbon dioxide emissions are little released during manufacturing thanks to the use of conversion devices. Solar energy may be used for many different purposes, such as providing light, warmth, distillation, and the production of fuels. Solar energy may be utilised to create electricity thanks to the photoelectric effect and the later development of PV cells
