What is the difference between photovoltaic and solar modules?
The terms “photovoltaics” and “solar modules” refer to different aspects of solar energy technology. Photovoltaics (PV) is a technology that converts sunlight directly into electricity using semiconductor materials. It encompasses the entire process and technology involved in this conversion, including the use of solar cells, panels and systems. Solar modules, on the other hand, are physical components made up of several solar cells linked together to form a panel. Essentially, solar modules are the hardware that implements photovoltaic technology.
What is the difference between photovoltaic and solar?
Photovoltaics and solar panels are related but not identical. Photovoltaics is the broader technology that describes the process of converting sunlight into electricity, while solar panels (or solar modules) are the specific devices that contain the photovoltaic cells and are used in solar energy systems. So, although solar panels are a key component of photovoltaic systems, the term photovoltaics covers the entire field, including research, development and system integration.
Deciding whether a solar or photovoltaic system is preferable depends on the context. In general, photovoltaic systems are a subset of solar systems. A photovoltaic system specifically refers to an installation that generates electricity from sunlight using PV technology. On the other hand, a “solar system” can refer to a broader range of solar technologies, including solar thermal systems for heating water. To generate electricity, a photovoltaic system is usually the choice, while solar thermal systems are used for heating purposes.
What is the lifespan of photovoltaic modules?
A photovoltaic system and a solar system are not always the same. A photovoltaic system is specially designed to produce electricity from sunlight through the use of photovoltaic cells. In contrast, a solar system can refer to any solar energy system, including solar thermal systems that use sunlight to heat water or air. The choice between these systems depends on whether the goal is to produce electricity or heat.
In terms of cost, solar panels and photovoltaic systems are often used interchangeably in casual conversations, but the cost comparison can vary depending on the specific application and technology. Generally speaking, the term “solar” could be used more broadly and could include various technologies such as solar thermal energy, which could be cheaper for heating than photovoltaic systems. However, if you compare solar panels (a component of photovoltaic systems) with other forms of solar technology, the cost will depend on the specific installation and system requirements.
