July 14, a resident in Shangrao formal roof PV systems and network operation and became Jiangxi ten thousand rooftop photovoltaic demonstration project in the successful completion of the first grid-acceptance of the project.

The project overall installed capacity of 5KW, assembly areas selected 20 Jinko 250W polycrystalline modules landlord intends to use a conventional string inverter 3kW group of Yu with 2kW photovoltaic micro-inverter (additional ECU energy manager, monitoring the work of each component) to form a small comparison system and within the system were installed in two inverter meter measurement, the purpose is to gather relevant power generation, photovoltaic power plants for subsequent civilian use inverters provide reliable data to support.

According to the project owner to reflect: "In the two sunny days, 2kW micro-inverter system throughout the day, made a 12 kilowatt system, 3kW string inverter system made a 16 kWh, 3kW system to send electricity to 18 degrees and micro-inverter system generating capacity balance. "Thus, taking into account the difference between installed capacity, power generation micro inverse system than about 13% higher than conventional systems.

June 7 this year, Jiangxi Province promulgated the "ten thousand rooftop photovoltaic demonstration project implementation plan (Trial)", will be selected in a range in the province conditional residential roof 10000, in accordance with the maximum not exceeding 5 kW per household, the average 3 kilowatts of installed capacity level construction of household photovoltaic power inverter with charger demonstration project. An engineering 1000-2000 households, and strive to build 10,000 within three years. Included ten thousand rooftop photovoltaic power generation demonstration projects will enjoy provincial special project grant funds, a project grant 4 yuan / peak watt, two works are tentatively scheduled 3 yuan / Wp.

5kW project as an example of that, removing subsidies Jiangxi $ 4 / W, owner's personal investment as long as two million yuan. If all the micro inverse system, the project annual electricity consumption of approximately 6000 KWh, such as the price of photovoltaic power plants can have one yuan / KWh (PV + desulphurization coal-fired electricity subsidies), then 3.3 years to recover the cost, even under the present desulfurization of coal tariff 0.485 yuan / KWh, it can also be as long as seven years to recover costs.

Yu photovoltaic micro inverse system with its multi-generation, superior security, flexible installed capacity, simplified system design and construction, to facilitate easy post-maintenance, intelligent monitoring and management, and many other advantages, caused a number of column names in Jiangxi Province suppliers concerned and sign cooperation agreements. China Sunergy (Nanjing) and Yu also can actively exchange negotiated strategic partners, merit Yu can use micro-inverse, to jointly promote the Jiangxi and other cities of the civilian system. In addition, Yu photovoltaic micro inverse system has also been a lot of residential users, especially high-end user groups of all ages, which shares the solar home systems installed in new green fashion ideas gradually into the lives of everyone.
