Solar Panel Stc Rating

The ptc of solar panels with stc rating of 260 watts varies in the gosolarcalifornia table.

Solar panel stc rating.

The percentage drop off depends largely on the type of solar panel materials used and the manufacturer. The stc rating of a solar module is determined by carefully controlling light and temperature in the testing environment. Every panel is assigned a nameplate power output value which is measured using stc standard test conditions. When shopping for a solar electric system for your home or business make sure that the dealer that you are speaking with is quoting you in actual ptc rated kilowatt hours per day.

Ptc power rating power ratings measure a solar panel s power output in watts. A higher power rating means that the panels are more effective at. As the panel heats up as they all do in the real world its output goes down. For sake of comparison i pulled every panel from the gosolarcalifornia table with an stc rating of 260 watts all 655 of them.

We are going to explain each of them to help clear it up. Stc and ptc ratings solar. The jinko solar jkm260p 60 watts polycrystalline module has a ptc rating of 238 2 watts and an stc rating of 260 watts. Test conditions and solar panels standard test conditions stc stc is the set of criteria that a solar panel is tested at.

Because the stc rating is a measurement calculated under ideal laboratory conditions it s not always a useful metric for designing your system. It is thus the name plate value of the solar panel and is given as the wattage of the module. In other words the stc rating of a solar panel is its output capacity under ideal conditions. Stc and ptc solar panel ratings.

The electric output performance of crystalline silicon and thin film pv modules are generally measured under standard test conditions stc ensuring a relatively independent. Stc stands for standard test conditions and is the major solar panel output performance testing condition used by most manufacturers and testing bodies. Solar panel power ratings. There are several terms and ratings that are associated with a solar panel s data sheet.

For instance a canadian solar 180w panel is 180w stc. All solar panels receive a nameplate power rating indicating the amount of power they produce under industry standard test conditions. An array made from 10 of these panels would be 1 800w stc. Their ptc ratings varied from 217 1 watts ptc stc 0 835 to 239 8 watts ptc stc 0 922 the canadian solar panel referenced above is at the high end of the scale ptc stc 0 919.
