Risusn is one of the first photovoltaic enterprises which were authorized by the State Ministry. We’ve already got ISO9001-2008 international quality system certification, TUV, CE, UL, ISO14001:2004, OHSAS18001:2007 and my other international certifications. We are strictly accordance with the quality management system and management process operation, ensusre the control quality target coverage every process.
RISUN'S "THE BIG DIPPER" PROJECTS ACHIEVE THE INITIAL TARGET
Our R&D team began to carry out "the Big Dipper" innovation project since 2010, strive to enhance the good quality product rate & conversion efficiency of solar cell, has realized mass production of 17.5 - 18% efficiency.
RISUN'S SOLAR PANLES PASSED PID TEST
Risun’s solar panels has passed the highest level anti PID test of PV industry -- TUV Rheinland PID certification test. At present, only few manufacturers in China passed the test. As solar panels are under long-term high intensity negative voltage, especially in the field of high temperature & humidity or inverter array with different grounding , the PID effect can lead to power reduction& poor performance, then effect power generation capacity of the whole system and the total output power. The condition of PID test is under 85% humidity, temperature 85 ℃, -1000 volts system bias, lasted for 96 hours. Test report shows, panels power attenuation is no more than 2.5%, much lower than the request index 5% of standard.
QUALITY GUARANTEE
For solar cells, we execution rigorous inspection standards for input & output’s appearance, size, performance, discrete rate, tensile, key process, etc. While for solar panels, the same maximum system voltage test of TPT and EVA peel strength, EVA transmittance, contact resistance of junction box, protective level, actuating force, sealant drying & solidifying time, toughened glass bending, impact resistance, tin coated copper strip test straightening tin coated resistivity, weldability, stretching strength, oxidation, webster hardness, bending and other key properties of aluminum frame execution approval strict inspection.
