What Is Stc Solar Panel

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.

What is stc solar panel.

Standard test conditions stc a solar panel is first tested right in the factory. This is because the stc system is demarcated to four zones based on solar radiation levels and other factors. 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.

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. This means that for a regular 5kw domestic. For example a 327w sunpower solar panel has a max power at stc of 327w.

Max power at noct. The value of an stc at any one time depends on market conditions. This nameplate value makes it easy for different panels and system sizes to be compared. When you purchase a solar power system from energy matters we have already discounted this value for you in your solar quote.

Stc stands for standard test conditions and is the major solar panel output performance testing condition used by most manufacturers and testing bodies. An array made from 10 of these panels would be 1 800w stc. Stc stands for standard test conditions and are the industry standard for the conditions under which a solar panel are tested. 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 is thus the name plate value of the solar panel and is given as the wattage of the module. The four zones are as follows. How does the solar credits scheme work. The panel is then flashed with fake sunlight.

Temperature of the cell 25 c. In other words the stc rating of a solar panel is its output capacity under ideal conditions. For instance a canadian solar 180w panel is 180w stc. 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 bad and good news government stc rebate for solar panels.
