Villagers spend 800,000 roof to build photovoltaic power stations: sell than rent spectrum-solar power station, solar energy-IT information
3-storey houses in the village in the city, nearly 40 rental alone, the rent can live without having to worry about song Xiao Dong had cost nearly 800,000 Yuan on the roof of their building a power station, he's thought about selling the income spectrum than the rent.
Building their own power plants into the grid electricity sold
"This is the year I did a most promising one thing. "Song Xiaodong said recently at a cost of nearly 800,000 Yuan on their rooftop PV system thing.
Song months GE Xiao Dong was Yanta district village, 3-storey house in the yard nearly 40 let alone, "our village far away from the city, the House is not very good rental, also received three thousand or four thousand dollars a month rent. "Song Xiaodong said.
Late last year, with biezongmao at home for the elderly in the village of roof mounted solar photovoltaic power generation system, "simply use their space, send to electric grid system, the equivalent of selling. "Biezongmao said. Biezongmao "power stations" after a period of operation, song Xiao Dong, think this thing is tricky, he found when it was biezongmao construction of an energy company Dong Liu, began planning for his design.
Song Xiaodong roof built "power station" after the electricity sector following yesterday has been in operation for half a month. Roof of his house are very open and two rows of photovoltaic panels can be achieved 64-kilowatt capacity, coupled with PV modules, two inverters, DC cable, steel brackets, connector, spray cleaning systems, as well as housing renovation, all well spent a total of nearly 800,000 yuan, "power system around 600,000 yuan to at least 20 years. ”
Song Xiaodong Dong Liu said as family viewing operation, individuals building their own solar system, you must first apply, the electricity sector after accepting it will give guidance to the field, after the completion of a test operation, "in the beginning you need to use the excess of electricity sold was sold, which decide whether to enjoy the level of preferential policies in the country. "Dong Liu said song Xiao Dong and biezongmao are the same, all grid-connected power generation, their power to purchase, the" solar PV cost per kilowatt-hour is about 0.6 Yuan, while they buy electricity comprised an 0.5 Yuan. "Unable to consume all in their own electric power, so also need to purchase a battery storage, and battery life was relatively short, so running costs are higher.
One-time 67 recover
Dong Liu introduced, since built solar PV system not only can enjoy province, and city of subsidies, and grid zhihou sold national grid of price also in each degrees 1 Yuan around, "like he home half months power 4000 degrees, a months down at least 8000 degrees, such on can got 8000 block money, a years down conservative estimated about 100,000 yuan, coupled with 64-kilowatt of capacity, province, and city of subsidies also can got 120,000 yuan above, such is down, he of one-time input just six or seven years on can recovered cost. "Song Xiaodong echoing says," this sure beats rent to mark. ”
Yesterday, at biezongmao House, his electricity from a solar photovoltaic panels directly to the first floor of the home, through a small inverter conversion for the two time lighting Director, "not lighting I was charging, battery can store. "Dong Liu says, if you need to store energy for everyday life, you need to buy a transformer connected to the electric car.
村民花80万楼顶建光伏发电站：卖电比收房租靠谱 - 光伏发电站,太阳能 - IT资讯
城中村里的3层民房，仅出租房就有近40间，本靠收房租也可以生活无忧，宋小东却花费近80万元在自家楼顶建了个发电站，他盘算着靠卖电的收益比收房租还靠谱些。
自建电站并入电网卖电
“这是这些年来我干得最靠谱的一件事。”宋小东说的是最近花费了近80万元在自家楼顶建光伏发电系统的事情。
宋小东是雁塔区月登阁村人，院子里的3层房子仅出租的就有近40间，“我们村离城区有些远，房子不太好出租，每个月也就收三四千块钱房租。”宋小东说。
去年年底，同村的别宗茂老人在自家楼顶架起了太阳能光伏发电系统，“简单说就是把自家的空地利用起来，发出来的电接入电网系统，相当于是卖电。”别宗茂说。别宗茂家“发电站”运转一段时间后，宋小东觉得这个事情挺靠谱，他找到当初给别宗茂家施工的一家能源公司负责人刘栋，开始筹划着给自家设计。
宋小东家楼顶自建“发电站”经过供电部门检验后，到昨日已经运行半个月。他家楼顶非常开阔，架了两排太阳能光伏板，可达到64千瓦的容量，加上光伏组件、两台逆变器、直流电缆、钢筋支架、连接器、喷淋清洗系统以及房屋改造等，全部建好总共花了近80万元，“发电系统60万元左右，最少可以用上20年。”
到宋小东家查看运转情况的刘栋说，个人自建太阳能光伏系统，首先必须提出申请，供电部门受理后会现场提出指导意见，完工后经过检验即可并网运行，“一开始就需要考虑自用之余将多余的电卖出去还是全部卖出去，这也决定了能否享受到国家政策的优惠程度。”刘栋说，别宗茂和宋小东都一样，全部发电并网，自家用电重新购买，“太阳能光伏发电每度电的成本在0.6元左右，而自己买电的话每度电0.5元。”因为自家用电也无法消耗全部发电，所以还需要购买蓄电池存储，而蓄电池的寿命又相对较短，所以运行成本也就更高了。
一次性投入六七年可回本
刘栋介绍，自建太阳能光伏系统不但能享受省、市的补贴，而且并网之后卖给国家电网的价格也在每度1元左右，“像他家半个月发电4000度，一个月下来最少8000度，这样就能拿到8000块钱，一年下来保守估计约10万元，加之64千瓦的容量，省、市的补贴还能拿到12万元以上，这样算下来，他的一次性投入只需六七年就可收回成本。”而宋小东也附和着说，“这样算下来，肯定比收房租靠谱。”
昨日，在别宗茂家，他将一块太阳能光伏板发的电直接接到自家一楼，通过小型逆变器转换，用于两处长时间照明，“不照明的时候我就给电动车充电，刚好蓄电池也能存储。”刘栋说，如果需要将存储的电能用于日常生活，只需要买个变压器接上电动车即可。
