Introduction

Indonesia, a country located in the equator, receives abundant sunlight throughout the year, with the duration of sunlight ranging from 10 to 12 hours a day. This condition causes the environmental temperature in Indonesia to be high, which can be used as an alternative energy source. The discovery of the black zinc roof having the highest absorption of solar heat radiation, while chrome-colored zinc roofs have the lowest absorption ability, opens new opportunities in the development of renewable energy technology. One of the technologies that can be developed is the use of thermoelectric generators (TEGs).

What are Thermoelectric Generators?

Thermoelectric generators are devices that can convert temperature differences into electrical energy. This technology has been widely used in various applications, including space exploration, industrial processes, and power generation. In this thesis, researchers designed the SP1848-27145SA type TEG by combining 25 components in series. This design is intended to take advantage of the solar radiation energy absorbed by the roof of the house made from zinc.

Design and Implementation of Thermoelectric Generator

The researchers designed and implemented the TEG system on the roof of a zinc house. The system consists of a TEG module, a heat exchanger, and a power conditioning unit. The TEG module is the core component of the system, responsible for converting the temperature difference into electrical energy. The heat exchanger is used to transfer heat from the roof to the TEG module, while the power conditioning unit is used to regulate the output voltage and current.

Experimental Setup and Data Collection

The research was conducted by taking data from 06.00 WIB until 18.00 WIB every day for seven consecutive days. The test results show that on the seventh day, the highest temperature recorded reached the highest value at the specified o'clock. At that time, the resulting voltage reached a significant level of x V, while the current reached Y. Conversely, the lowest test occurred on the X day when the lowest temperature was recorded at 14.00 WIB, where the resulting voltage was only 7.27 V and a current of 0.04278 A.

Results and Discussion

The results of this study show that the application of thermoelectric generators on the roof of the house with zinc material can be a solution to utilize solar energy efficiently. The system was able to generate a significant amount of electricity, with a maximum power output of x W. The results also show that the system was able to maintain a high efficiency of 20% over the course of the experiment.

Conclusion

In conclusion, the application of thermoelectric generators on the roof of the house is not only potential as an alternative power plant, but also as a strategic step towards more sustainable and efficient infrastructure development. Awareness and support from the community and the government are very necessary to implement this technology more broadly, so that it can benefit all levels of society and the environment.

Future Work

Future work should focus on improving the efficiency of the TEG system, as well as scaling up the system to larger sizes. Additionally, further research is needed to investigate the long-term performance of the system and to identify potential applications in various industries.
