So far, the electricity we use everyday comes from fossil energy such as coal. However, keep in mind that coal is limited in number and can be used up at any time. In addition, the use of fossil fuels is also a major cause of global warming. We should consider using other energy sources.
Being on the equator, sunlight in Indonesia is known to be very abundant. The sun shines all year long, an advantage that not all countries can have. Then, why does Indonesia not only use solar power plants?
1. The use of solar energy in Indonesia is only 0.05 percent
On a global scale, China and the United States lead in the use of solar power plants. Meanwhile, in Indonesia, the utilization of solar energy is still very lacking. This was explained by the Director of Planning and Development of Infrastructure for Renewable Energy and Energy Conservation (EBTKE) of the Ministry of Energy and Mineral Resources, M. Arifin, in a written statement on the page esdm.go.id.
“The use of solar energy in Indonesia is only 0.05 percent of the potential. So there are still many challenges that must be solved together, one of which is the high cost of PLTS production,” said Arifin.
Another challenge, PLTS cannot be transported and lacks human resource capacity in mastering PLTS technology.
2. Even though solar power plants have a myriad of benefits, you know!
Page Green Match mentions that solar energy has the least impact on the environment compared to other energy sources. Among other things, it does not produce greenhouse gases, does not pollute water, requires little water for maintenance and does not cause noise.
As long as there is light, solar energy can be applied anywhere. This is very useful for remote areas without access to other electricity sources. Of course, being environmentally friendly and cheaper is another advantage of using solar energy.
3. Even so, Indonesia also has the biggest solar power plant!
Inaugurated in the village of Oelpuah, Kupang, NTT on December 27, 2015 by the President of the Republic of Indonesia Joko Widodo, PLTS Kupang has a capacity of 5 MW. Thus, the National Electronic Institution (LEN) participated in assisting PLN in overcoming the electricity deficit in the region.
Standing on an area of 7.5 hectares, thousands of solar panels are stretched above it. One solar panel produces 230 watts of electricity. The NTT region is considered very suitable for developing solar power plants because for nine months from one year, NTT was always illuminated by sunlight.
4. Expensive investment costs become the constraints of PLTS in Indonesia
High investment costs are an obstacle to the delays in the establishment of PLTS. At least, it costs US $ 2 million or around Rp.26 billion from every 1 MWp. If the PLTS is built with a capacity of 5000 MW, then the cost required is around Rp 165 trillion. The Ministry of Energy and Mineral Resources overcomes this problem by opening offers to the private sector.
Even so, PLTS does not require large operational costs. The costs required are only for the maintenance of solar modules, such as watering water to remove dust and cutting grass around the module. Compare this with diesel power plants that require thousands of liters of diesel to run electricity.
