A solar power plant (PLTS) is a system designed to convert sunlight into electrical energy. This technology harnesses solar energy to supply electricity across various scales, ranging from small to large.
The operating principle of a solar power plant relies on the photovoltaic effect, which occurs when sunlight strikes the semiconductor material within a solar cell. When sunlight hits the solar cell, light photons mobilize electrons within the semiconductor material, thereby generating an electric current.
The implementation of solar power plants aligns with the 2021–2023 Electricity Supply Business Plan (RUPTL) of PT PLN (Persero). The document outlines the government's plan to increase power generation capacity by 35 gigawatts (GW) and promote the development of new and renewable energy (EBT).
Advantages of Solar Power Plants
Solar power plants offer several advantages. One key benefit is their ability to protect the Earth from climate change caused by greenhouse gases.
What are the other advantages of solar power plants? Read on to find out.
1. Sunlight is Available Everywhere
Sunlight is an energy source that can be utilized anywhere. Whether you live in an urban area or along the coast, sunlight is available.
This advantage can be leveraged to establish power plants in remote areas—specifically the 3T regions (frontier, outermost, and underdeveloped areas). These regions often struggle to access electricity due to their remote locations; however, this issue can be resolved by installing solar power plants in these areas.
2. Compatibility with Batteries and the Electrical Grid
Photovoltaic systems generate energy during the day. The generated energy is stored in storage units to supply electricity to those who need it. Subsequently, the electrical energy can be distributed directly into the electrical grid.
This energy distribution allows communities to save on electricity costs while simultaneously serving as a source of income and a driver of social change.
3. Offers Flexibility
Solar energy can be used to generate thermal energy by heating fluids or by utilizing modern thermodynamic solar power systems. This flexibility is highly advantageous for both developers and users.
Solar energy generates minimal noise compared to fossil fuels. Aside from a few cooling components, solar power plants are capable of efficiently harvesting energy under a wide range of conditions.
4. Low Maintenance
Power plants require routine maintenance to extend their operational lifespan. Maintenance frequency typically depends on the specific system specifications and operational mechanics of the plant.
Photovoltaic cells have a lifespan of 20–25 years. This results in lower maintenance requirements for solar power plants compared to fossil-fuel-based power plants.
5. Boosting Revenue and Creating Jobs
Solar power plants create significant employment opportunities for engineers and technicians within the power generation sector.
Harnessing sunlight as an energy source provides an economic boost and attracts investment into the country.
Research from ScienceDirect indicates that the global transition to 100% renewable energy by 2050 will result in the photovoltaic sector employing 22 million people worldwide. This figure is based on projections by IRENA (International Renewable Energy Agency).
6. Increasing Property Value
The average annual energy expenditure per person in the United States is Rp 47,316,224, covering both transportation and residential energy needs. Solar power systems can reduce or eliminate these costs after installation, offering long-term savings since sunlight is free.
Installing solar panels can significantly increase a property's resale value. Many homebuyers understand the benefits of residential solar panels; a key advantage is that the system is already installed and ready for immediate use.
Studies show that most homeowners experience an increase in resale value of Rp 91,640,301 per installed kilowatt. This means installing a 3.1-kilowatt system could raise your home's resale value by Rp 279,060,300. In addition to providing electricity, homes equipped with solar panels stay cooler because the panels absorb the sun's heat instead of allowing it to beat directly down on the roof.
