Stc Solar Panel

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 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. 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 term solar panel is used colloquially for a photo voltaic pv module. Stc stands for standard test conditions and are the industry standard for the conditions under which a solar panel are tested.

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. 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 pv module is an assembly of photo voltaic cells mounted in a framework for installation.

Stc is the set of criteria that a solar panel is tested at. There are three standard test conditions which are. 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 solar panels will always have higher ratings at stc compared with notc.

Temperature of the cell 25 c. 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. The bad and good news government stc rebate for solar panels.

It is a nominal or name plate value. The panel is then flashed with fake sunlight. This means that for a regular 5kw domestic. Standard test conditions stc a solar panel is first tested right in the factory.

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. Stc stands for standard test conditions. For example take a look at the following product.

How does the solar credits scheme work. Solar panels heat up considerably during operation so the temperature considered is 45 3 c. This includes the cells temperature of 25 77 light intensity of 1000 watts per square meter which is. For instance a kyocera 180watt panel is 180watts stc.

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