Stc Solar Panel

The stc rating of a solar module is determined by carefully controlling light and temperature in the testing environment.

Stc solar panel.

Stc stands for standard test conditions and is the major solar panel output performance testing condition used by most manufacturers and testing bodies. This means that solar panels will always have higher ratings at stc compared with notc. The bad news is that the government rebate for solar panels has fallen over the years and a progressive plan to phase out this rebate begins on 1 st january 2017 with an initial 6 reduction which will continue each year until 2032. This includes the cells temperature of 25 77 light intensity of 1000 watts per square meter which is.

These are measured under lab conditions of 1000w per sq meter of sunlight with a standard spectrum etc. The light spectrum is the same as for stc. For instance a kyocera 180watt panel is 180watts stc. Standard test conditions stc a solar panel is first tested right in the factory.

Stcs are issued with qualifying solar power systems and solar panels and can be redeemed for a dollar value that is deducted from the cost of the solar system. The electric output performance of crystalline silicon and thin film pv modules are generally measured under standard test conditions stc ensuring a relatively independent. The value of an stc at any one time depends on market conditions. Stc stands for standard test conditions and are the industry standard for the conditions under which a solar panel are tested.

A pv module is an assembly of photo voltaic cells mounted in a framework for installation. Temperature of the cell 25 c. By using a fixed set of conditions all solar panels can be more accurately compared and rated against each other. Photo voltaic cells use sunlight as a source of energy and generate direct current electricity a collection of pv modules is called a pv panel and a system of panels is an array.

An array made from 10 of these panels is considered 1 800watts stc. Solar panels heat up considerably during operation so the temperature considered is 45 3 c. When you purchase a solar power system from energy matters we have already discounted this value for you in your solar quote. This means that for a regular 5kw domestic.

It is a nominal or name plate value. The light source in the laboratory is calibrated so that precisely 1 000 watts per square meter of solar light falls on the photovoltaic panel. A windspeed of 1 m s is considered with air at 20 c. 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.

There are three standard test conditions which are. Stc stands for standard test conditions. The term solar panel is used colloquially for a photo voltaic pv module. The bad and good news government stc rebate for solar panels.

The panel is then flashed with fake sunlight. Stc is the set of criteria that a solar panel is tested at.
