What is the difference between a solar cell and a solar panel?

Answer 1

Solar cells and solar panels are two essential components of photovoltaic systems used to capture and convert sunlight into electricity. While they are interconnected and serve a common purpose, they have distinct characteristics and functions. Here are the key differences between solar cells and solar panels:

Size and Output

Solar Cell: Solar cells are relatively small and produce a limited amount of electrical power. They are typically square or rectangular in shape and have a size ranging from a few square centimeters to a few square inches.

Solar Panel: Solar panels are much larger and can generate a significantly higher amount of electricity compared to individual solar cells. They consist of multiple solar cells wired together in a specific configuration.

Function

Solar Cell: The primary function of a solar cell is to directly convert sunlight into electricity. When exposed to sunlight, solar cells generate a direct current (DC) electrical output.

Solar Panel: Solar panels serve as an array of interconnected solar cells. They collect the electrical output from individual solar cells and generate usable electrical power for various applications.

Application

Solar Cell: Solar cells are used in various electronic devices and small-scale applications where a compact and lightweight power source is required. Examples include calculators, watches, and portable chargers.

Solar Panel: Solar panels are employed in larger-scale applications, such as residential and commercial solar power systems, solar farms, and grid-connected installations. They are capable of providing electricity to homes, businesses, and even entire communities.

Electrical Characteristics

Solar Cell: Individual solar cells typically have a voltage output in the range of 0.5 to 0.6 volts. They are low-power devices designed for integration into larger arrays.

Solar Panel: Solar panels have a higher voltage output, usually in the range of 20 to 40 volts or more, depending on their size and configuration. This higher voltage is more suitable for delivering power over longer distances.

In summary, while solar cells and solar panels share the common goal of converting sunlight into electricity, they differ in terms of size, output, function, application, and electrical characteristics. Solar cells are the fundamental units, and solar panels are the larger systems that combine multiple solar cells to generate substantial electrical power. Both play crucial roles in the world of solar energy and contribute to the advancement of sustainable power generation.

Answer 2

A solar panel is made up of a series of solar cells. The number of cells in any one panel is dependant on its size.

So a cell is part of a panel, just like a living human cell is part of the human body.
