Solar energy

• Solar energy is the energy received by the planet from the sun, which can be in the form of visible light or other forms of electromagnetic radiation.
• Photovoltaic panels are specialized panels used to convert visible light to electricity.
• Concentrated solar power uses the heat of the sun to generate electricity.
• In Luzon, there are 12 operating solar power plants.
• In Visayas, there are 11 solar power plants.
• In Mindanao, solar power plants are found in Bukidnon, Misamis Oriental and South Cotabato.
• The advantages of using solar energy include its renewability, fewer safety risks in operation of solar power plants, and low operating cost.
• The disadvantages of using solar energy include that collection of solar energy only happens during daytime, the energy harnessed depends on seasons and hours of the day, and solar panels are not very efficient (average of 20% efficiency).
