光伏发电原理
图片

光伏发电主要原理是半导体的光电效应。 当光子照射到金属或半导体表面上时,它的能量可以被金属或半导体中某个电子全部吸收,电子吸收的能量足够大,能克服物体内部引力做功,离开原有物体表面成为光电子,光电子所形成的电流称为光电流。

说到光伏发电,就不得不提一下“太阳能发电”,很多人认为光伏发电就是太阳能发电,其实不然,它们之间的关系是:光伏发电只是太阳能发电的一种,太阳能发电还包括了光化学发电、光感应发电和光生物发电。

光伏发电有辐射吗?




家用光伏发电站由光伏组件、光伏逆变器、光伏支架以及光伏线缆等构成,整个发电过程是直接将光能转化为电能,没有任何化学变化以及核反应,所以光伏发电是安全可靠、无噪声、无辐射等绝对干净(无公害)的清洁能源。

光伏发电不仅没有辐射,还可以反射一些太阳光里面的有害的紫外线,所以它不仅不会对我们的身体健康造成危害,反而会帮我们反射一部分有害的紫外线!

雨雪天气还能发电吗?

在大部分人的认知里,光伏发电想要发电就需要有阳光,尤其是南方地区,赶上梅雨季节,很多装了光伏或者想装光伏的朋友们就开始担忧了,阴雨天气会不会对光伏发电造成很大的影响呢?冬天要是下雪了还能不能发电呢?

光伏发电在获得能源的同时,确实与四季、昼夜及阴晴等气象条件有关。

但是在雨雪天气下,虽然没有了太阳光的直射,光伏电站的发电量相对来说会偏低一点,但也并非就不发电了,光伏组件在弱光条件下也可以做到一定程度的发电。但是在某些特殊情况下,太阳辐射过低,光伏发电系统的工作电压如果达不到逆变器的启动电压,系统就不会工作。

虽然天气这个因素我们没办法控制,但是我们可以做好日常生活中对光伏组件的维护。

也不要担心雨雪天气会对光伏组件有什么损伤

光伏组是需要定时清洗维护的

下雨天,就当免费清洗光伏组件了

这不就又省了一笔? 

Prionsabal ghiniúcháin cumhachta photóvoltaach
picture
The main principle of photovoltaic power generation is the photoelectric effect of semiconductors. When a photon irradiates the surface of a metal or semiconductor, its energy can be fully absorbed by an electron in the metal or semiconductor. The energy absorbed by the electron is large enough to overcome the internal gravity of the object and leave the original object surface to become photoelectrons. The current formed by photoelectrons is called photocurrent.

Nuair a bhaineann le ghiniúint cumhachta fótáilteach, ní mór dúinn a lua "ghiniúint cumhachta solaire". Measann go leor daoine gur ghiniúint cumhachta solaire é ghiniúint cumhachta solaire é an ghiniúint photáilteach. I ndáiríre, ní. Is é an gaol eatarthu ná go bhfuil ghiniúint cumhachta solaire amháin de chineál ghiniúint cumhachta solaire. Áiríonn ghiniúint cumhachta solaire freisin ghiniúint cumhac

Is there radiation from photovoltaic power generation?
Tá stáisiún cumhachta photovoltaic teaghlaigh comhdhéanta de mhodúil photovoltaic, inverters photovoltaic, tacaíochtaí photovoltaic agus cáblaí photovoltaic. Is é an próiseas iomlán chun fuinneamh solais a thiontú go díreach i bhfuinneamh leictreach gan aon athrú ceimiceach agus imoibrithe núicléach. Dá bhrí sin, is fuinneamh glan (gan truailliú) é an ghiniúint photovoltaic cumhachta, le sábháilteacht, iontaofacht, gan torann

Ní amháin nach bhfuil radaíocht ag an gcruthú cumhachta grianghraif, ach is féidir freisin beaga ultravioleta dochracha a léiriú i solas na gréine, ionas nach ndéanfaidh sé dochar do ár sláinte, ach cabhróidh sé linn beaga ultravioleta dochracha a léiriú!

Féadfar leictreachas a ghiniúint i bhfad bánta agus sneachta?

I bhformhór na ndaoine a thuiscint, tá gá le solas a thabhairt do ghiniúint cumhachta photovoltaic más mian leat leictreachas a ghiniúint, go háirithe san Deisceart. Sa tseasúr bánta, thosaigh go leor cairde a shuiteáil photovoltaic nó a bhfuil fonn ort fótovoltaic a shuiteáil ag obair. An mbeidh tionchar mór ag aimsir chomsach agus bánta ar ghiniúint cumhachta photov If it snows in winter, can it generate electricity?

However, in rainy and snowy weather, although there is no direct sunlight, the power generation capacity of photovoltaic power station will be relatively low, but it is not that there is no power generation. Photovoltaic modules can also generate power to a certain extent under weak light conditions.
