We first put forward in the industry long hardware warranty and linear power quality and commitment. As follows: Ten years hardware warranty. Power warranty of 25 years: single crystal components, attenuation in the first year does not exceed 4% attenuation of about 0.67% in subsequent years, 25 yea

We are in an industry first proposed ultra long hardware warranty and linear power quality commitment. as follows: 10 hardware warranty. 25 power quality assurance: single-crystal components, first year volume attenuation does not exceed 4 per cent each year thereafter, attenuation capacity of about

We pioneered the long hardware warranty in the industry and linear power warranty commitments. As follows: ten-year hardware warranty. Warranty 25 power: single crystal components, attenuation of not more than one year 4%, attenuation of about 0.67% every year in the future, guaranteed not less than
