Standard Test Condiitions Solar Panels

By using a fixed set of conditions all solar panels can be more accurately compared and rated against each other.

Standard test condiitions solar panels.

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. Standard test conditions stc refers to the fixed set of laboratory conditions under which every solar module is tested. 5 0 b 2013 automatic electrical controls part 1 general requirements. Solar panel output is expressed in units of watts w and represents the panel s theoretical power production under ideal sunlight and temperature conditions.

What are standard test conditions stc. 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. They enable the evaluation and comparison of different solar panel types by determining current voltage and power of solar pv panels under comparable test conditions.

Temperature of the cell 25 c. Stc stands for standard test conditions and are the industry standard for the conditions under which a solar panel are tested. There are three standard test conditions which are. Standard test method for determining thermal performance of tracking concentrating solar collectors iec 60730 1 ed.

Standard test conditions stc a solar panel is first tested right in the factory. All solar panels are rated by the amount of dc direct current power they produce under standard test conditions. Standard test conditions stc tests another central solar panel test procedure is the standard test conditions tests stc tests which are run for all solar pv panels. 1 1 temperature of the cell 25 c.

The panel is then flashed with fake sunlight. Iec 61215 tests also help determine a panel s performance metrics at standard testing conditions stc.
