经常有人咨询：“光伏发电安装价格多少钱一平方 ”或者“一平方米能安装多少光伏”?需要多少钱......? 光伏问题中的“一平方米”这样的问题，应该怎么回答呢：一是光伏不是按面积平方米来安装的，二是按电量来回答，与面积没多大的关系。不过这个问题确是业主迫切知道的事情，我们为业主考虑从专业角度为大家试着解释一下“光伏一平方米”的问题。

 一、1平方米屋顶能装多少光伏?
分布式光伏电站的面积通过换算，结果是这样的：每平方米可在地面和平面水泥屋顶安装100瓦左右的组件;对于有坡度的彩钢板屋顶和斜坡瓦屋顶来说每平方米可安装100-120瓦组件。虽然我们给出一个数据，但安装前还是要进行前期勘察，如有遮挡、障碍等，还得重新计算，这仅是一个参考数据。
二、1平方米的电站需要多少钱?
这个问题确实不专业，因为光伏电站的计量单位是瓦(W)或千瓦(KW)，现在的市场安装价格应该在8-10元/瓦左右，一平方米可以安装100瓦左右，那么我们可以不专业的回答您：安装光伏每平方米大约需要800-1000元左右的资金。这也是一个参考，如果安装有难度，并网距离较远，业主提出一些加固的想法，都会增加电站工程的造价。
三、1平方米每天能发多少度电?
一般情况下每千瓦在华北地区大约平均每天发电4—5度，合1平方米平均每天发电0.4—0.5度左右，一年的话就是140――180度电左右。
四、1平方米光伏一年收入多少钱?
收入多少与国家政策有着千丝万缕的联系，2018年的补贴政策调整了，主要是：度电补贴由0.42元下调到0.37元;三类地区标准脱硫煤上网电价由0.85元/度下调到0.75元/度，根据1平方米每年的发电量，轻松地算出1平方米光伏电站的一年收益约为100元---140元左右。

People often consult: "how much is the price of photovoltaic power generation installation per square meter" or "how much photovoltaic can be installed per square meter"? How much does it cost......?Photovoltaic problem in the "one square meter" such a question, how should answer it: one is that photovoltaic is not installed according to the area of square meters, the other is to answer according to the quantity of electricity, and the area does not have much relationship. But this problem is the owners of urgent things to know, we consider for the owners from a professional point of view for everyone to try to explain the "photovoltaic square meter" problem.

One, 1 square meter roof can be installed how much photovoltaic?

The area of the distributed photovoltaic power station is converted into something like this: about 100 watts of components per square meter can be installed on the ground and on the concrete roof; 100 to 120 watts of components per square meter can be installed for sloping colored steel roofs and sloped tile roofs.Although we give a data, we still need to carry out preliminary investigation before installation. If there is shelter, obstacle, etc., we also need to recalculate. This is only a reference data.

How much does a power station of 1 square meter cost?

This question is really not professional, because the unit of measurement of photovoltaic power stations is watts (W) or kilowatts (KW), the current market installation price should be about 8-10 yuan/watt, a square meter can be installed about 100 watts, then we can not professional answer you: the installation of photovoltaic per square meter about 800-1000 yuan of capital. This is also a reference. If the installation is difficult and the distance from the grid is long, the owner will put forward some reinforcement ideas, which will increase the cost of the power station project.

3. How many kilowatt-hours of electricity can a square meter produce every day?

Under normal circumstances, each kilowatt in North China generates about 4 to 5 kilowatts of electricity per day, or about 0.4 to 0.5 kilowatts per square meter per day, or about 140 to 180 kilowatts per year.

Four, 1 square meter of photovoltaic a year how much money?

The amount of income is closely related to national policies. In 2018, the subsidy policy was adjusted, mainly: subsidy per kilowatt hour was lowered from 0.42 yuan to 0.37 yuan; The on-grid price of standard desulphurized coal in the three regions has been reduced from 0.85 yuan/KWH to 0.75 yuan/KWH. Based on the annual power generation capacity of 1 square meter, it can be easily calculated that the annual income of 1 square meter photovoltaic power station is about 100 yuan --140 yuan.
