Stc Solar Panel

For example take a look at the following product.

Stc solar panel.

The term solar panel is used colloquially for a photo voltaic pv module. A windspeed of 1 m s is considered with air at 20 c. 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. The stc rating of a solar module is determined by carefully controlling light and temperature in the testing environment.

For instance a kyocera 180watt panel is 180watts stc. 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. How does the solar credits scheme work. The value of an stc at any one time depends on market conditions.

The bad and good news government stc rebate for solar panels. This includes the cells temperature of 25 77 light intensity of 1000 watts per square meter which is. By using a fixed set of conditions all solar panels can be more accurately compared and rated against each other. An array made from 10 of these panels is considered 1 800watts stc.

There are three standard test conditions which are. Temperature of the cell 25 c. It is a nominal or name plate value. The panel is then flashed with fake sunlight.

The electric output performance of crystalline silicon and thin film pv modules are generally measured under standard test conditions stc ensuring a relatively independent. This means that solar panels will always have higher ratings at stc compared with notc. This means that for a regular 5kw domestic. When you purchase a solar power system from energy matters we have already discounted this value for you in your solar quote.

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. 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. The light spectrum is the same as for stc. Standard test conditions stc a solar panel is first tested right in the factory.

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. Stc is the set of criteria that a solar panel is tested at. Stc stands for standard test conditions. Solar panels heat up considerably during operation so the temperature considered is 45 3 c.

These are measured under lab conditions of 1000w per sq meter of sunlight with a standard spectrum etc. 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.
