The terms “PV” (Photovoltaic) and “solar” are often used interchangeably in the context of solar energy, but they have slightly different meanings.
- Photovoltaic (PV): This specifically refers to a type of technology used in solar panels to convert sunlight into electricity. PV technology is based on the photovoltaic effect, where certain materials can generate an electric current when exposed to sunlight.
- Solar Energy: This is a broader term that encompasses all technologies and methods used to harness energy from the sun. This includes photovoltaic systems for generating electricity, but also solar thermal systems for heating, solar cooking, solar heating for buildings, and more.
So, in essence, PV is a subset of solar energy technologies. It’s not that one is better than the other; rather, PV is a specific method within the broader category of solar energy solutions. The choice between PV and other solar technologies depends on the specific application and energy needs. For instance, if the goal is to generate electricity, PV is the relevant technology. If the goal is to heat water or air, solar thermal solutions might be more appropriate.
