ABOUT SUNVIS
SHANGHAI SUNVIS NEW ENERGY CO., LTD, as a Solar Panel Manufacturer in China, specializes in providing high quality solar panels for home, commercial, government and industrial applications. It is a high-tech private enterprise integrating R&D, production, design, installation and after-sales service.
We can provide professional solar power system, solar lighting system, solar battery storage system and solar hybrid inverter and so on many kinds of energy-saving and environmental protection products and projects, is the advocate and promoter of new energy.
STC stands for "standard test conditions," while NOCT stands for "normal operating cell temperature." STC is a measure of a solar panel's performance under perfect lab conditions, while NOCT is a measure of the solar panel's performance in the real world, under real-world operating conditions.
In real working conditions, the overall module temperature is usually much higher and could reach 40-50 ⁰C , which drops the performance of pv modules by about 0.5% for each 1°C rise in temperature.
NOCT: Cell surface light intensity intensity = 800W/m2 , air temperature = 20°C, wind speed = 1m/s, bracket structure = rear back open.
STC: Standard test conditions 25 degrees, atmospheric mass AM1.5 , solar radiation: 1000W/m2.
PERC cells are a modification of traditional solar cells.
PERC cells have a conversion efficiency of 6% to 12% more than traditional solar cells, and the appearance have an extra layer on the back of the cell compared to traditional cells.
Therefore it can capture more sunlight and convert it into electricity through that extra layer, thus making PERC cells more efficient than conventional cells.
- Lower packaging losses
- Shadow tolerance reduces hot spot risk
- Low current to reduce hot spot temperature
- Shadow tolerance reduces power loss
