What is a PV Panel when talking about Solar?
A PV panel, also known as a solar panel, is an assembly of photovoltaic (PV) cells mounted in a (usually rectangular) frame. Solar panels capture sunlight as a radiant energy source, converted into electric power in direct current (DC) electricity.
PV panels are used in various applications, including powering homes and businesses, providing electricity for off-grid applications, and generating electricity for utility-scale power plants.
PV panels comprise several individual cells, each of which is made from a semiconductor material such as silicon. When sunlight hits a PV cell, it causes electrons to be released from the atoms in the semiconductor material. These electrons then flow through the cell, creating an electric current.
The amount of electricity that a PV panel can generate depends on several factors, including the amount of sunlight that hits the panel, the efficiency of the cells, and the panel size.
PV panels are a clean and efficient way to generate electricity. They do not produce any emissions, and they do not require any water to operate. PV panels are also relatively low-maintenance, requiring only occasional cleaning and inspection.
The cost of PV panels has declined significantly in recent years, making them more affordable for homeowners and businesses. As a result, the use of PV panels is growing rapidly worldwide.
