經(jīng)常有人咨詢：“光伏發(fā)電安裝價(jià)格多少錢(qián)一平方 ”或者“一平方米能安裝多少光伏”?需要多少錢(qián)......? 光伏問(wèn)題中的“一平方米”這樣的問(wèn)題，應(yīng)該怎么回答呢：一是光伏不是按面積平方米來(lái)安裝的，二是按電量來(lái)回答，與面積沒(méi)多大的關(guān)系。不過(guò)這個(gè)問(wèn)題確是業(yè)主迫切知道的事情，我們?yōu)闃I(yè)主考慮從專(zhuān)業(yè)角度為大家試著解釋一下“光伏一平方米”的問(wèn)題。

 一、1平方米屋頂能裝多少光伏?
分布式光伏電站的面積通過(guò)換算，結(jié)果是這樣的：每平方米可在地面和平面水泥屋頂安裝100瓦左右的組件;對(duì)于有坡度的彩鋼板屋頂和斜坡瓦屋頂來(lái)說(shuō)每平方米可安裝100-120瓦組件。雖然我們給出一個(gè)數(shù)據(jù)，但安裝前還是要進(jìn)行前期勘察，如有遮擋、障礙等，還得重新計(jì)算，這僅是一個(gè)參考數(shù)據(jù)。
二、1平方米的電站需要多少錢(qián)?
這個(gè)問(wèn)題確實(shí)不專(zhuān)業(yè)，因?yàn)楣夥娬镜挠?jì)量單位是瓦(W)或千瓦(KW)，現(xiàn)在的市場(chǎng)安裝價(jià)格應(yīng)該在8-10元/瓦左右，一平方米可以安裝100瓦左右，那么我們可以不專(zhuān)業(yè)的回答您：安裝光伏每平方米大約需要800-1000元左右的資金。這也是一個(gè)參考，如果安裝有難度，并網(wǎng)距離較遠(yuǎn)，業(yè)主提出一些加固的想法，都會(huì)增加電站工程的造價(jià)。
三、1平方米每天能發(fā)多少度電?
一般情況下每千瓦在華北地區(qū)大約平均每天發(fā)電4—5度，合1平方米平均每天發(fā)電0.4—0.5度左右，一年的話就是140――180度電左右。
四、1平方米光伏一年收入多少錢(qián)?
收入多少與國(guó)家政策有著千絲萬(wàn)縷的聯(lián)系，2018年的補(bǔ)貼政策調(diào)整了，主要是：度電補(bǔ)貼由0.42元下調(diào)到0.37元;三類(lèi)地區(qū)標(biāo)準(zhǔn)脫硫煤上網(wǎng)電價(jià)由0.85元/度下調(diào)到0.75元/度，根據(jù)1平方米每年的發(fā)電量，輕松地算出1平方米光伏電站的一年收益約為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.
