解讀：太陽(yáng)能光伏發(fā)電安裝價(jià)格多少錢(qián)一平方？光伏經(jīng)過(guò)幾年的發(fā)展，現(xiàn)在已經(jīng)飛入尋常百姓家。但是很多人在安裝光伏電站時(shí)，還是不知道光伏電站是怎么收費(fèi)的？按照屋頂面積還是安裝容量？對(duì)光伏發(fā)電有投資意向的人都比較關(guān)注受益安裝成本，今天我們來(lái)聊聊成本和收益這件經(jīng)濟(jì)題。
一、裝光伏多少錢(qián)一平方呢？
光伏一般是按照裝機(jī)功率、瓦數(shù)來(lái)算，如果按照面積可以換算一下，一般8-10個(gè)平方可以裝1KW，如果你想裝10KW就需要80-100個(gè)平方的屋頂面積，價(jià)格大概4500元每千瓦，10KW就是35000元；
那么一平方米的面積能安裝多少光伏？成本大約是多少？
在這里，瑞元天科要告訴大家的是：
1、光伏電站不是按照面積來(lái)安裝的；
2、光伏電站的安裝是按照電量來(lái)的。
二、一平方米光伏每天能發(fā)電量是多少？
發(fā)電量是按照當(dāng)?shù)厮幘S度和光照時(shí)間、強(qiáng)度、溫度來(lái)綜合計(jì)算的，星馳新能源給大家大體估量一下，通常情況下在華北地區(qū)的話，每千瓦平均每天發(fā)電4.5度，計(jì)算下來(lái)就是：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。
三、一平方米光伏電站一年下來(lái)總收益大約有多少錢(qián)？
光伏電站的總收益和國(guó)家政策分不開(kāi)的，國(guó)家光伏發(fā)電補(bǔ)貼政策每年度都會(huì)有一些調(diào)整了?！蛾P(guān)于落實(shí)好2021年新能源上網(wǎng)電價(jià)政策有關(guān)事項(xiàng)的函》。其中明確了2021年新建新能源項(xiàng)目上網(wǎng)電價(jià)政策：對(duì)2021年納入當(dāng)年中央財(cái)政補(bǔ)貼規(guī)模的新建戶用分布式光伏項(xiàng)目，其全發(fā)電量補(bǔ)貼標(biāo)準(zhǔn)按每千瓦時(shí)0.03元執(zhí)行。那光伏電站每發(fā)一度電的真正收益是多少？我們以全額上網(wǎng)為例，光伏電站發(fā)一度電的收益=本省脫硫煤店家+國(guó)補(bǔ)0.03元。根據(jù)這個(gè)計(jì)算公式，便可以精確的計(jì)算光伏電站的受益了。

Interpretation: solar photovoltaic power installation price how much a square?  After several years of development, photovoltaic has now flown into the ordinary people's homes.  But many people do not know how to charge for photovoltaic power stations when they install them.  By roof area or installation capacity?   People who are interested in investing in photovoltaic power generation pay more attention to the cost of installation. Today, let's talk about the economic issue of cost and revenue.  

A, how much is the photovoltaic square?  

Photovoltaic is generally calculated according to installed power, watts, if according to the area can be converted, generally 8-10 square can install 1KW, if you want to install 10KW will need 80-100 square roof area, the price is about 4500 yuan per kilowatt, 10KW is 35000 yuan;  

So how much pv can be installed in one square meter?  What is the approximate cost?  

Here, Ruiyuan Tianke would like to tell you:  

1. Photovoltaic power stations are not installed according to area;  

2. The installation of photovoltaic power stations is based on the quantity of electricity.  

Two, one square meter of photovoltaic power generation per day is how much?  

Electricity is according to local place dimension and the illumination time, strength and temperature to integrated computation, generally weigh the star chi new energy for everybody, usually in north China area, per kilowatt power a day on average 4.5 degrees, calculate down is: 1 square meters a day on average power 0.4-0.5 degrees or so, a year is about 140-180 KWH.  

Three, a square meter of photovoltaic power station in a year about how much money?  

The total revenue of photovoltaic power stations and national policies are inseparable, and the national photovoltaic power subsidy policy will have some adjustments every year.   Letter on Implementing the New Energy On-grid Pricing Policy in 2021.  It clearly defines the feed-in tariff policy for new energy projects in 2021: For new household distributed photovoltaic projects that will be included in the scale of central financial subsidy in 2021, the subsidy standard of full generation will be implemented at 0.03 yuan per kilowatt-hour.  So what is the true revenue per kilowatt of electricity generated by a photovoltaic plant?  Taking full Internet access as an example, the income of photovoltaic power station generating one kilowatt of electricity = local desulphurized coal stores + national subsidies of 0.03 yuan.  According to this calculation formula, the benefits of photovoltaic power stations can be accurately calculated.
