In order to solve the problem of recycling old clothes of college teachers and students

an intelligent clothes recycling station powered by distributed photovoltaic power generation system was designed under the dormitory building of a college in Nanchang. The structure and working principle of the solar clothes recycling station were introduced

and the design and selection of photovoltaic modules and grid connected inverter were discussed in detail. The new development mode of "photovoltaic + X" was prospected. The total power of the system was 5.4 kW. It was composed of 18 photovoltaic modules

6 series and 3 parallel

and 5.5 kW grid connected inverter was selected; Then the cost and power generation of the system were analyzed and calculated. In the first year

5 842.8 kW·h power could be generated. According to the photovoltaic subsidy policy

the cost could be recovered in 7.6 years

which had good economic and environmental benefits.
