            光伏發電成為農村老百姓的理財“新寵”

            6年可回本”“無后續投入”“可至少運轉25年”……

            帶著明顯投資或理財意味的宣傳,加上政府部門的政策支持,近年來,戶用分布式光伏發電站在部分地區的農村不大不小地“火了一把”。

            戶用分布式光伏電站,是安裝在家庭屋頂上的一座小型太陽能發電裝置,既環保又綠色。若干光伏發電板組成陣列,加上逆變器等必要組件,就可在農村住宅的屋頂搭建一座戶用分布式光伏發電站。隨著光伏發電在農村下沉市場的興起,炊煙裊裊、雞犬相聞中,這種頗具科技感的新能源設備成為一道風景線。

            在現有的戶用分布式光伏發展中,“自發自用、余電上網”“全額上網”等發電上網模式,可以使這種小型電站生產的電力能源成為商品,并入國家公共電網,成為一種新的創收方式,這也使這類家庭式新能源項目具備一定的投資價值。

            記者在調查中發現,戶用分布式光伏發電在經歷多年推廣后,已經具備一定的用戶基礎,在部分農村市場的發展已形成規模;另一方面,光伏發電本身的技術特點以及農村市場具體條件的限制,也使這類項目在一些地區的發展遭遇瓶頸。

            在今年電力能源緊缺的背景之下,光伏產業鏈整體呈現增長態勢,也由此引發業界關于“光伏發電能否解決電力緊缺”的猜想。特別是在當前農村戶用分布式光伏發電已具備一定數量的基礎上,“靈活分布”“以量取勝”成為一種樸素的“求解”思路。


            It can be repaid in 6 years, has no subsequent investment, and can operate for at least 25 years...

            In recent years, household distributed photovoltaic power stations have become popular in some rural areas with obvious investment or financial promotion and policy support from government departments.

            Household distributed photovoltaic power station is a small solar power generation device installed on the roof of a home, which is both environmentally friendly and green. An array of photovoltaic panels, together with the necessary components such as an inverter, can set up a household distributed photovoltaic power station on the roof of a rural house. With the rise of photovoltaic power generation in the rural sinking market, the smoke curling, the smell of the new energy equipment with a sense of science and technology has become a landscape.

            In the current development of household distributed photovoltaic, power generation online modes such as "self-use, surplus electricity online" and "full electricity online" can make the electricity energy produced by such small power stations become commodities and incorporated into the national public grid as a new way of income generation, which also makes this kind of family new energy projects have a certain investment value.

            The reporter found in the investigation, after years of promotion, household distributed photovoltaic power generation has a certain user base, in part of the rural market has formed a scale of development; On the other hand, the technical characteristics of photovoltaic power generation and the specific conditions of the rural market also make the development of this kind of projects in some areas encounter bottlenecks.

            Under the background of power energy shortage this year, the photovoltaic industry chain as a whole shows an increasing trend, which also causes the industry to speculate on "whether photovoltaic power generation can solve the power shortage". Especially on the basis of a certain amount of distributed photovoltaic power generation for rural households, "flexible distribution" and "winning by quantity" have become a simple "solution" idea.

            In 1839,

            French physicist A.E. Becquerel made an accidental discovery

            A volt cell consisting of two pieces of metal immersed in a solution

            It creates an extra volt of electric potential when it's hit by sunlight

            This is the photoluminescent Volt effect

            The picture

            Later people used this principle

            Creating solar cells that can generate electricity

            The picture

            We know that

            In order to get electricity, two conditions must be met

            1. There are enough free electrons

            2. The electrons have to move in a directional way

            So how does photovoltaic power work?

            Solar energy cell

            It's made of two silicon plates

            The picture

            Why do batteries look like this?

            Atoms are made up of nuclei and electrons

            And the electrons will go around the nucleus in several layers

            And it was found that

            Usually you have eight electrons in your outermost shell

            Atoms are more stable

            But most atoms don't have eight. What is photovoltaic power generation?
