現(xiàn)在一些企業(yè)對于屋頂建設(shè)光伏電站已經(jīng)不像過去那樣疑慮,智慧用能,節(jié)約用電成本一直被高度關(guān)注。


以生產(chǎn)型企業(yè)為例,它們往往是高能耗的單位,適逢用電高峰期,用電問題是他們面對的頭等大事,加上這幾年國家號召節(jié)能減排,為了保證產(chǎn)生,一些企業(yè)往往會自發(fā)的建設(shè)備用應(yīng)急電源,用來彌補(bǔ)用電高峰時(shí)電力不足的問題。 光伏發(fā)電是一種取之不盡用之不竭的新能源,這幾年也得到國家層面的大力支持與推動(dòng),從集中式電站到分布式電站,國家出臺了一系列細(xì)則與補(bǔ)貼辦法,企業(yè)與個(gè)人對于光伏發(fā)電的認(rèn)知也有了更大的改變。

目前光伏電站主要有兩類應(yīng)用,一種是大型地面電站,主要分布在西北人跡稀少的地方;其次就是分布式光伏電站,比如家庭屋頂、工商業(yè)屋頂、漁光互補(bǔ)等,而工商業(yè)屋頂作為分布式光伏電站的重要應(yīng)用市場,現(xiàn)在也被推到很高的層面。企業(yè)廠房通常具有 屋頂面積大、屋面平整,遮擋物少,自身用電量大,電價(jià)高等特點(diǎn),非常適合安裝自發(fā)自用為主的光伏發(fā)電系統(tǒng)。 工商業(yè)光伏電站不受資源分布地域的限制,利用建筑屋面閑置資源,無噪聲,無污染。

工商業(yè)屋頂光伏的四大好處
01  盤活固定資產(chǎn) ,降低企業(yè)電費(fèi)支出,企業(yè)還將受益至少20年
利用企業(yè)屋頂建設(shè)光伏電站對于企業(yè)來說是一次性投資,每天都是穩(wěn)定收益。大家都知道工商業(yè)電費(fèi)遠(yuǎn)高于民用電,每年電費(fèi)支出都是不菲,而光伏發(fā)電安裝后,實(shí)現(xiàn)自發(fā)自用,余電上網(wǎng),除了可以降低用電成本,還能享受國家對于光伏發(fā)電的補(bǔ)貼。
02  降低企業(yè)能耗,緩解用電緊張問題。
對于生產(chǎn)型企業(yè)能耗問題一直存在,特別是用電高峰期,企業(yè)采用了各種發(fā)電系統(tǒng)進(jìn)行補(bǔ)充,可是投入高,產(chǎn)出低。所以,很多企業(yè)選擇了光伏發(fā)電,因?yàn)橥顿Y成本相對低,發(fā)電相對穩(wěn)定,并且光伏發(fā)電時(shí)間與企業(yè)用電高峰時(shí)段基本一致,真正達(dá)到削峰作用。
03  節(jié)能減 排,改善環(huán)境,提升企業(yè)社會形象
企業(yè)屋頂安裝光伏電站后實(shí)現(xiàn)太陽能、建筑的綜合利用,不僅讓企業(yè)達(dá)到節(jié)能減排的效果,企業(yè)還盡到改善周邊環(huán)境的社會責(zé)任,增加了美譽(yù)度。
04  隔熱降溫,改善員工工作環(huán)境

光伏電站建設(shè)于廠房之上,在一定程度上起到降溫的效果,在夏季尤為明顯,通常情況下可使車間降低3-6度,對于從事生產(chǎn)勞作的工人來說無疑改善了工作環(huán)境,對于企業(yè)來講也降低了降溫所產(chǎn)


碳中和”大背景下,全球光伏產(chǎn)業(yè)發(fā)展?jié)摿薮?/span>

隨著工業(yè)的發(fā)展和人類活動(dòng)規(guī)模的擴(kuò)大,對化石能源和自然資源的過度開發(fā)利用導(dǎo)致溫室氣體排放顯著增長;根據(jù)聯(lián)合國《2021 年排放差距報(bào)告》顯示,2021 年全球二氧化碳排放量將出現(xiàn)強(qiáng)勁反彈,化石能源二氧化碳排放量可能增長 4.8%。溫室氣體的過量排放將導(dǎo)致全球升溫并引發(fā)熱浪、洪水、干旱、海平面上升等一系列自然災(zāi)害,積極應(yīng)對碳排放問題已成為全球共識。

減少碳排放最有效的途徑就是提高非石化能源的消費(fèi)比例,截至 2020 年末,全球已有超過 130 個(gè)國家制定了可再生能源發(fā)展目標(biāo),有近 40 個(gè)國家設(shè)立了“碳中和”的目標(biāo);美國、歐盟、英國、日本等主要發(fā)達(dá)經(jīng)濟(jì)體均承諾在 2050年前實(shí)現(xiàn)“碳中和”。

根據(jù) IRENA 預(yù)測,在全球 2050 年實(shí)現(xiàn)碳中和的背景下,到 2050 年電力將成為最主要的終端能源消費(fèi)形式,占比達(dá) 51%。其中,90%的電力由可再生能源發(fā)電供應(yīng)。微信圖片1

其中,光伏作為目前資源最易得、性價(jià)比最高的可再生清潔能源,肩負(fù)在碳中和時(shí)代,成為全球主力能源的重任。根據(jù) IRENA 預(yù)測,2050 年全球光伏累計(jì)裝機(jī)量將達(dá)到 14,000GW。以 2021 年全球光伏累計(jì)裝機(jī)量約為 850GW 測算,增長空間達(dá)到 16.5 倍,成長確定性高。

而從短期來看,2022 年,在光伏發(fā)電成本持續(xù)下降和全球綠色復(fù)蘇等有利因素的推動(dòng)下,全球光伏市場將繼續(xù)維持快速增長趨勢。根據(jù)中國光伏行業(yè)協(xié)會預(yù)計(jì),“十四五”期間全球每年新增光伏裝機(jī)約 232-286GW。

Nowadays, some companies are no longer as skeptical about building rooftop photovoltaic power plants as they used to be. Smart energy use and cost saving have always been highly valued.

Taking production-oriented enterprises as an example, they are often high energy consuming units, and during peak electricity consumption periods, electricity consumption issues are their top priority. In addition, in recent years, the country has called for energy conservation and emission reduction. In order to ensure production, some enterprises often spontaneously build backup emergency power sources to compensate for the shortage of electricity during peak electricity consumption. Photovoltaic power generation is an inexhaustible new energy source that has received strong support and promotion from the national level in recent years. From centralized power stations to distributed power stations, the country has introduced a series of detailed rules and subsidy measures, and the understanding of photovoltaic power generation by enterprises and individuals has also undergone greater changes.

At present, there are two main types of applications for photovoltaic power plants. One is large-scale ground power plants, mainly distributed in sparsely populated areas in the northwest; Secondly, there are distributed photovoltaic power stations, such as home roofs, industrial and commercial roofs, and complementary fishing and lighting. As an important application market for distributed photovoltaic power stations, industrial and commercial roofs are now being pushed to a very high level. Enterprise factories typically have large roof areas, flat roofs, few obstructions, high electricity consumption, and high electricity prices, making them very suitable for installing photovoltaic power generation systems primarily for self use. Industrial and commercial photovoltaic power stations are not limited by the geographical distribution of resources, utilizing idle resources on building roofs, without noise and pollution.

Four Benefits of Industrial and Commercial Roof Photovoltaics

Revitalizing fixed assets and reducing electricity expenses for enterprises will benefit them for at least 20 years

Building photovoltaic power plants on the roof of enterprises is a one-time investment for enterprises, with stable returns every day. Everyone knows that industrial and commercial electricity costs are much higher than civilian electricity, and the annual electricity expenditure is not cheap. After the installation of photovoltaic power generation, achieving spontaneous self use and surplus electricity connected to the grid can not only reduce electricity costs, but also enjoy national subsidies for photovoltaic power generation.

02 Reduce enterprise energy consumption and alleviate electricity shortages.

For production oriented enterprises, energy consumption issues have always existed, especially during peak electricity consumption periods. Enterprises have adopted various power generation systems to supplement, but the investment is high and the output is low. So, many companies choose photovoltaic power generation because the investment cost is relatively low, the power generation is relatively stable, and the photovoltaic power generation time is basically consistent with the peak electricity consumption period of the enterprise, truly achieving peak shaving effect.

03 Energy conservation and emission reduction, improving the environment, and enhancing the corporate social image

After installing photovoltaic power plants on the roof of enterprises, the comprehensive utilization of solar energy and buildings is achieved, which not only achieves the effect of energy conservation and emission reduction, but also fulfills the social responsibility of improving the surrounding environment, increasing reputation.

04 Heat insulation and cooling to improve employee work environment

The construction of photovoltaic power plants on top of the factory building has a certain degree of cooling effect, especially in summer. Usually, it can reduce the workshop temperature by 3-6 degrees, which undoubtedly improves the working environment for workers engaged in production work and reduces the electricity cost incurred by cooling for enterprises.


Against the backdrop of "carbon neutrality", the global photovoltaic industry has enormous potential for development

With the development of industry and the expansion of human activities, the Overexploitation of fossil energy and natural resources has led to a significant increase in greenhouse gas emissions; According to the United Nations' 2021 Emission Gap Report, global carbon dioxide emissions will experience a strong rebound in 2021, with fossil energy carbon dioxide emissions likely to increase by 4.8%. Excessive emissions of greenhouse gases will lead to global warming and trigger a series of natural disasters such as heatwaves, floods, droughts, and rising sea levels. Actively addressing carbon emissions has become a global consensus.


The most effective way to reduce carbon emissions is to increase the proportion of non petrochemical energy consumption. As of the end of 2020, more than 130 countries worldwide have set renewable energy development goals, and nearly 40 countries have set "carbon neutrality" goals; Major developed economies such as the United States, the European Union, the United Kingdom, and Japan have all pledged to achieve "carbon neutrality" by 2050.
According to IRENA's prediction, in the context of achieving carbon neutrality globally by 2050, electricity will become the main form of terminal energy consumption, accounting for 51%. Among them, 90% of the electricity is supplied by renewable energy generation.
Among them, photovoltaic, as the most easily available and cost-effective renewable clean energy, shoulders the responsibility of becoming the global main energy source in the era of carbon neutrality. According to IRENA's prediction, the cumulative installed capacity of global photovoltaics will reach 14000GW by 2050. Based on the global cumulative photovoltaic installed capacity of approximately 850GW in 2021, the growth potential is 16.5 times higher, indicating high growth certainty.

1000kVA變壓器可以承受多少kW的用電量?

1000kVA變壓器可以承受多少kW的用電量?

問題“有一臺1000kVA的老式變壓器,現(xiàn)有負(fù)荷約200kW,如果要增加約600kW的新負(fù)載,這臺變壓器能否承受?”這個(gè)問題首先涉及到一個(gè)概念,那就是kVA和kW之間的關(guān)系及區(qū)別。kVA(千伏安)是視在功率的單位,kW(千瓦)則是有功功率的單位。除了視在功率和有功功率以外,還有無功功率,無功功率的單位是kvar(千乏)。
