㳀谈:光伏发电安装价格多少钱一平方
返回列表 来源: 发布日期: 2021.11.15 浏览次数:

光伏成本下降,市场平价到来,所以再也不像以前一样,现在光伏发电安装价格多少钱一平方?7八年前,一瓦需要20多块了。现在安装电站,一瓦的平均价格在4-5元左右,一个10KW的电站只需要4万块就能搞定。当然,你要选择可靠的大品牌,要保证组件/逆变器/支架等都是大厂的产品,才能保证光伏电站使用寿命能达到30年。当然,家庭光伏发电的收益包括三部分:
一、补贴赚钱:市县补贴(各地略有不同),不论是自己用了还是卖了,只要发的电都有补贴。
二、节省电费:发电自己用,不用交电费,等于赚钱了。
三、卖电赚钱:用不完的电卖给国家,卖电价格按照当地燃煤脱硫机组标杆电价0.56元/度左右。(各地电价略有不同)。
四、投资回报测算
以浙江地区为例,安装一个10KW的家庭电站,按照市场价格,投资约4万元。,一年可发11500kw/h,按照30%自用,70%卖给国家电网来算:
补贴收益:11500*0.08=920元(不含省级、地级补贴)
节省电费收益:11500*30%*0.52(电费)=1794元
卖电收入:11500*70%*0.4153=3343元
综合下来,一年的收入:920+1794+3343=6057元
差不多7年时间就可以回本,光伏电站的平均运行时间是25年,等于后面的时间是纯收益。
如果你还不清楚安装光伏电站能带来多少收益,你可以下载一个APP 碳盈协同 里面可以给你仔细的测算安装光伏电站需要花多少钱,以及你的具体收益如何。可以了解一下。

Pv cost drops, market parity comes, so it is no longer the same as before, now photovoltaic power installation price how much money per square meter?  Seven or eight years ago, a watt cost more than 20 bucks.  Now to install power stations, the average price of one watt is about 4-5 yuan, and a 10KW power station only needs 40,000 yuan.  Of course, you need to choose reliable big brands, and ensure that components/inverters/brackets are products of big factories, so as to ensure that the service life of photovoltaic power stations can reach 30 years.  Of course, the benefits of home PV include three parts:  

A, subsidies to make money: city and county subsidies (around the slightly different), whether it is used or sold, as long as the electricity has subsidies.  

Two, save electricity: power generation for their own use, do not pay electricity, equal to make money.  

Iii. Profit from electricity sales: when the electricity is not used up, it is sold to the state at a price of 0.56 yuan/KWH according to the benchmark price of local coal-fired desulfurization units.   (Electricity prices vary slightly.)  

Fourth, investment return measurement  

Take Zhejiang province as an example, to install a 10KW household power station, according to the market price, the investment is about 40,000 yuan.  , 11500KW /h per year, calculated as 30% for self-use and 70% sold to State Grid:  

Subsidy income: 11500*0.08=920 Yuan (excluding provincial and prefectural subsidies)  

Saving electricity revenue: 11500*30%*0.52(electricity)=1794 YUAN  

Electricity sales income: 11500*70%*0.4153=3343 yuan  

Put it all together, annual income: 920+1794+3343=6057 yuan  

It takes almost 7 years to make a return. The average operating time of photovoltaic power station is 25 years, which is equal to the net income of the following time.  

If you are not sure how much money you will get from installing a photovoltaic power station, you can download an APP called Carbon Profit Synergy that will give you a detailed estimate of how much it will cost to install a photovoltaic power station and how much you will get in return.   You can see that.
