Xu Pengfei is an
electronics engineer for almost 10 years in the PV inverter. December 21, 2012,
Xu Pengfei 9 voltaic panels installed on your own roof. In addition to meet
their own use, the surplus electricity is also
grid tie inverter full acquisition.
From December 21, 2012 Alex photovoltaic power plant began formal grid tie inverter , Xu Pengfei also replace the name of the microblogging, "PV bathtub" is replaced by "China's first residents photovoltaic, and daily reports on time to the 2927 fans operation of the power station. Xu Pengfei will be a day time to update the blog, report on the operation of photovoltaic power plants on the roof. Alex month net profit calculated in accordance with the network desulfurization price of 0.4 yuan, 42.76 yuan.
Alex roof, 9 voltaic panels in two rows of inclined fixed in the cement pile foundation, wind grid tie inverter the total installed capacity of 2 kW DC photovoltaic panels issued via a single cable into the inverter to hang on the wall, and was converted to alternating current, and then through the wire into the the Xu 2 meter measured separately from the user to use the power and photovoltaic power generation. In addition to the supply of Alex own use, the surplus electricity is sold to the the Qingdao power grid tie inverter.
Xu Pengfei told reporters, The installed capacity of 2 kW photovoltaic power plants, including components, accessories,wind grid tie inverter including the construction, the entire investment is $ 20,000, "If you put aside familiar factors in the industry, the general public is installed set may have to 30000 yuan. "
Qingdao annual sunshine time is 2300 hours, taking into account the rainy, cloudy day special weather, this power plant is expected to an annual power generation of 2600 degrees, calculated in accordance with the Qingdao residents electricity at $ 0.54 per unit, annual electricity savings of 1,404 yuan, 15 years construction costs can be recovered within. Attenuation of power inverter efficiency set of PV modules to appear after 25 years of use, according to 25 years of life, cost recovery, the residents can enjoy free electricity for more than 10 years.
"And you're using green electricity, environmental protection, pollution-free, according to the estimates of a power inverter, a year can save 0.91 tons of standard coal, reduce 2.5922 tons of carbon dioxide emissions."
Xu Pengfei introduction, has entered the market of solar photovoltaic application stage, rather than installed smaller families, factory payback period will be shorter.
He pointed out that the current electricity prices of many enterprises in the yuan, about twice higher than the residential electricity prices, the payback period is also shortened half. Enterprises to build photovoltaic power plants, because of the larger, procurement, construction costs than families low, and enterprise multi-night electricity during the day electricity is less consistent with the laws of photovoltaic power inverter, the electricity to be fully used.
In accordance with the new regulations, the State Grid commitment to free grid full acquisition of surplus power of 6 MW of distributed PV power generation project. 6 MW, which is an hour generating 6,000 degrees, the installed capacity of 20,000 degrees a day, enough to meet the electricity needs of most SMEs.
