Guangrao County, Shandong Province, rice village Sunzhuang Village, the villagers Liu Fulin home roof, a piece of solar panels arranged in neat rows.
Speaking of the installation of photovoltaic power plant on the roof, Liu Fulin said, "Before the Spring Festival, listen to the children suggested that the installation of photovoltaic power plants installed in solar panels, installed on the roof, not occupied, and environmental protection, more importantly, it is cheaper to use. I installed a 5.5 kWh distributed photovoltaic power plant, a total of 22 250-watt solar group, each 1080 yuan, together with inverters, lines, etc., estimated that the cost of 30,000 dollars.
"The electricity used during the day is sent out from the roof. There are quite a few places for electricity in the home, at least 100 kWh in a month, and over 50 yuan in electricity bills. Now I can generate electricity, cook rice, and cook water." Liu Fulin wife Say.
Photovoltaic power generation and electricity on the grid, which is more cost-effective? Liu Fulin forget an account. "Power generation more than 8000 degrees a day, about 22 degrees on power generation, excluding monthly use 100 degrees of electricity, but also the remaining more than 7000 degrees of electricity, according to the price of 0.64 yuan per kWh, a year is 4,500 yuan. The warranty period of the power station is 25 years, so that the 30,000 yuan invested in the previous period can earn back the profits in 7 years. "
Accompanying the sea, the new energy company engineer Zhang Shengli said: "The account so calculated, photovoltaic power generation not only self-sufficiency, but also free access to the national grid, in accordance with the purchase price of desulfurization power of 1 yuan per kilowatt. More than 4 years will be able to recover the cost.More importantly, energy saving, 5.5 kilowatt hours of power plants generate 8,000 degrees per year, can save about 3 tons of standard coal, reducing carbon dioxide emissions by 9 tons.
Liu Fu Lin said that the folks come to see more fun, and intended to install a lot.
