家用光伏电站多少钱

       家用光伏是指建造在自家的屋顶上或者庭院里的用来自发自用余电上网的太阳能光伏发电站。其组成部分主要是包括太阳能光伏组组件板、逆变器、支架、电缆等，它与太阳能热水器有本质的区别。

   家用光伏电站多少钱 是根据业主的房屋屋顶可使用面积来估算的，一般来说家用房屋面积在50-150平方之间，如果屋顶可使用面积在80平方，那么大概可估算安装8KW，目前户用的每瓦大概在5.5元-6元/瓦，那么8KW=8000*5.5/8000*6，大约是44000元至48000元之间。按照目前市场的情况80平方建设成本大概在此范围内，按照上海的光照条件80平方年发电量大概是8760度电，除去部分上网卖给国家电网的收益电费之外，一年可节约电费人民币5000元左右，这还是按照平价电费计算，在上海很多的家庭电费是经常超三档的，按照国家电网计费超过三挡后每度电费计更是高达近一元。如下图所示。

Household photovoltaic refers to the solar photovoltaic power station built on the roof or in the courtyard for the spontaneous use of surplus electricity to connect to the Internet. Its components mainly include solar photovoltaic module board, inverter, support, cable, etc., which is essentially different from solar water heater. The cost of household photovoltaic power station is estimated according to the usable area of the owner's house roof. Generally speaking, the area of household house is between 50-150 square meters. If the usable area of roof is 80 square meters, it can be estimated that 8kw can be installed. At present, the cost of household photovoltaic power station is about 5.5 yuan - 6 yuan / watt, so 8kw = 8000 * 5.5/8000 * 6, about 44000 yuan to 48000 yuan. According to the current market situation, the construction cost of 80 square meters is probably within this range. According to the lighting conditions of Shanghai, the annual power generation of 80 square meters is about 8760 kwh. In addition to the income from selling electricity to the State Grid on the Internet, it can save about 5000 yuan a year. This is still calculated according to the parity electricity charge. In Shanghai, many household electricity charges often exceed the third grade, According to the State Grid, the electricity charge per kilowatt hour is up to nearly one yuan after exceeding the third gear.
