Shandong Zhaori New Energy Tech. Co., Ltd. is specialized in researching and manufacturing solar tracking systems, and has obtained patent of invention from Europe, USA, Canada, Australia, Japan, South Korea, Thailand, India, Brazil, South Africa and China, as well as TUV and CE certificates. This tracking system owns simple structure, low cost, less power consumption, wide tracking range, high accuracy, high reliability, high cost performance, fast installation and convenient transportation. It only increases PV plant investment by 10%-15%, while promotes generating capacity by 30%-50% (higher latitude, more efficient); meanwhile, we produce flat single axis solar tracker and tilted single axis solar tracker, which have simple structure, smart assembling and excellent terrain adaptability. At medium and low latitude region, it increases investment about 5-8%, while promotes generating capacity by 15%-25% and brings more rewards for investors.
