  • Detail

At the beginning of the new year, a residential building located in Linhai City, Zhejiang Province, was independently applied by Mr. He as a private owner. The installed capacity of the system was 5.88kwp. A total of 24 245W polysilicon photovoltaic modules and a sununo-tl5k dual circuit MPPT inverter provided by TRICRYSTAL new energy were used. At the beginning of the new year, a residential building located in Linhai City, Zhejiang Province, was independently applied for by Mr. He as a private owner by installing temperature and pressure sensors in the tires. The installed capacity of the system was 5.88kwp. A total of 24 245W polysilicon photovoltaic modules and a sununo-tl5k dual MPPT inverter provided by TRICRYSTAL new energy were used. In this project, the strain type, inductance type, differential transformer type, eddy current type and Hall sensor are often used to detect the spontaneous self use and residual power on mode, that is, the power generated during the day is used by the family, the excess power is incorporated into the power, and the power is taken from the power at night

on the last day of February, the weather was relatively sunny, and the power generation capacity of Mr. He's photovoltaic system reached 17kwh. By using the webserver monitoring software independently developed by Sanjing new energy and monitored by either Ethernet or Webportal web mode, users can observe that the system has started generating electricity from 7:00 a.m. local time to 6:00 p.m., and reached the peak period of 3.5kwh at about 12:00 p.m. The roof photovoltaic system can basically meet the self-sufficiency of household users

home PV system has been quite popular in Europe and the United States and other countries, with relatively perfect corresponding support policies, and is the main terminal form of exported PV products. In China, with the launch of the solar roof plan and the golden sun demonstration project by the government, many places have also formulated supporting solar photovoltaic power generation subsidy policies and roof plans. The draft for comments on the 12th Five Year Plan of renewable energy has specifically set the construction objectives of the roof photovoltaic system: it is planned to reach 3million kilowatts in 2015 and 25million kilowatts in 2020. The positive attitude of the State Council executive meeting on photovoltaic development and the successive introduction of a series of favorable policies have initially revealed the domestic market demand. The success of the first household photovoltaic system may become the start of the domestic small and medium-sized photovoltaic system market. The successful acceptance and connection of the household photovoltaic system this time undoubtedly opened a skylight for the depressed photovoltaic market hit by the European and American anti-dumping measures
