Distributed photovoltaic power generation into the rural Jiangxi Province

Jincheng Avenue, Lianhua County, Pingxiang City, Jiangxi Province, Yang New Village recently a novelty, the villagers Zhu Jianbing home roof tops of 18 solar panels, light generation, not only spontaneous personal use, but also to sell excess electricity to the power company.

Once upon a time, in their own roof still unheard of photovoltaic power generation in rural Jiangxi, but now the villagers took much interest in this novelty. Zhu Jianbing home less than 100 square meters large roof, the reporter saw 18 black solar inverter face-south direction. "Roof power plants, installed capacity of 4 kW, according to local sunshine time, the estimated annual energy generation of 5000 - 6000 kwh.

This is well distributed power grid service work, since March 1, the State Grid Corporation of China, Jiangxi Province, the first residents of the user distributed photovoltaic power generation and grid projects. Signed a contract with the electricity sector through the metering device and network installation, and network acceptance and commissioning, Zhu Jianbing "small power plant began generating electricity.

"We not only can use distributed power to its own power supply, can also be used up the electricity per unit (kWh) of 0.485 yuan price sold to the national grid." Said Zhu Jianbing, he had a habit of study circuit, home the tape recorder was torn down several times. In 2009, he converted the two used Photovoltaic Panels for home small building lighting street lamps powered success, more and more of the photovoltaic power generation fascinated.

In October 2012, Zhu Jianbing in their own roof, huh photovoltaic power generation, and a set of equipment cost $ 3 million. In February this year, the power company to Lotus for installation of 220 volt distributed photovoltaic power generation project on March 12 grid. On March 22, the Lotus-powered technical staff door for a return visit. View and net metering, 10 days after the entry grid of photovoltaic power generation, self-occupied 18 degrees 240 degrees spontaneous grid electricity at night to use the big net charge of 35 degrees, normal run.

The equipment design life of 20 years, full cost recovery is expected in 10 years, the rest of the 10-year profit. Stamped on nearly 100 square meters of the roof insulation layer have to spend more than 20,000 yuan, "said Zhu Jianbing, not only the insulation as effective as solar panels also vain wastage of resources.

According to the "opinions" on doing distributed power grid service work, the China State Grid allows photovoltaic, wind power, natural gas, distributed power into the national grid, and provide concessions and network conditions, strengthen the supporting grid construction, optimization and network processes, simplifying network procedures, and improve service efficiency.

Zhu Jianbing home "power plant" smooth grid, the local power supply department has developed a special access program, sent technical personnel to provide free and install the cable, smart meters, and more than 1000 yuan cost savings. This family of photovoltaic power generation can ease the supply pressure of the electricity sector during the peak period.

"Lotus County Power Supply Company customer service center director of the Physiological - Zhu Jianbing home grid electricity exports to neighboring households. Meanwhile, he also pointed out that, distributed power grid to the electricity sector has brought a lot of challenges." Solar http://www.solarpanelcellonline.com The panels will light conversion to DC, and then by the inverter to convert DC current to alternating current to grid.

If the inverter fails, the DC power directly into the grid, and will be a great impact on the power grid, and even a security incident. "Physiological - residents distributed photovoltaic power generation after rigorous safety testing of the electricity sector, in order to apply grid.
