Solar Panel Stc Definition

Standard test conditions are the laboratory conditions under which all pv modules are tested.

Solar panel stc definition.

Stc in an acronym for factory standard test conditions which is 1 000 watts per square meter solar irradiance 1 5 air mass and a 25 degrees c. Standard test conditions stc stc is the set of criteria that a solar panel is tested at. There are three standard test conditions which are. A collection of pv modules is called a pv panel and a system of panels is an array.

A pv module is an assembly of photo voltaic cells mounted in a framework for installation. Manufacturers use stc testing to ensure that photovoltaic panels with similar energy output can be sold and used together. As the panel comes off the production line a worker or robot places the panel on a flash table and hooks up the positive and negative leads to a measuring device. It can be said that stc is a benchmark for comparing different types of pv modules even if they are not from the same provider.

1 1 temperature of the cell 25 c. Ptc is an acronym for pv usa test conditions which were developed at the pv usa test site at the university of davis california. By using a fixed set of conditions all solar panels can be more accurately compared and rated against each other. Stc stands for standard test conditions.

Arrays of a photovoltaic system supply solar electricity to electrical equipment. If you want an easy way to compare the efficiency of one solar panel to another look for the stc rating. These are measured under lab conditions of 1000w per sq meter of sunlight with a standard spectrum etc. Since voltage and current change based on temperature and intensity of light among other criteria all solar panels are tested to the same standard test conditions.

The most common application of solar energy collection outside agriculture i. Standard test conditions stc a solar panel is first tested right in the factory. The term solar panel is used colloquially for a photo voltaic module. There are three standard test conditions which are.

By using a fixed set of conditions all solar panels can be more accurately compared and rated against each other. It is a nominal or name plate value. Stc stands for standard test conditions and is the major solar panel output performance testing condition used by most manufacturers and testing bodies. Solar panels guides stc stands for standard test conditions and are the industry standard for the conditions under which a solar panel are tested.

The electric output performance of crystalline silicon and thin film pv modules are generally measured under standard test conditions stc ensuring a relatively independent comparison and output evaluation of different solar pv modules. Photo voltaic cells use sunlight as a source of energy and generate direct current electricity.
