这座发电站属于经营性质，所发出的电“全额上网”，相当于经营者将电卖给当地电力公司，从中赚取利润。据赵明提供的合同信息显示，经销商对发电站工程承包内容除设备的购置和安装以外，还负责帮助赵明办理发电站并网方面的手续。这对于能源专业外行的赵明来说，完全是“一站式服务”，“只需要以3.5元/瓦的建设单价付款就行了”。

"It does pay for itself in six or six and a half years based on current generation efficiency and revenues." "The warranty period of photovoltaic panels is 25 years, which means the plant can operate for at least 25 years. After the cost is covered, the rest of the operation period can be cost-free and profitable," said Zhao Ming, owner of a household distributed photovoltaic power station.

In October 2021, after a period of investigation, Zhao signed a contract with a local distributor of photovoltaic power generation projects and invested in the construction of a household distributed photovoltaic power station in a small village in the northwest of Shanxi Province, his hometown.

Zhao Ming's power station was built on the roof of the village's own houses and on the open space in the courtyard, covering a total area of "about 300 square meters equivalent to 8 ~ 9 rooms". The power station was 79.17kW and the total investment was 277,100 yuan.

The power station is a business, and the electricity generated is "fully online", which means that the operator sells the electricity to the local power company and makes a profit from it. According to the contract information provided by Zhao Ming, in addition to the purchase and installation of equipment, the dealer is also responsible for helping Zhao Ming handle the formalities of connecting the power station to the grid. For Zhao, a layman specializing in energy, this is a "one-stop service". "You only need to pay the construction unit price of 3.5 yuan per watt."
