安裝一套光伏電站多少錢(qián)?安裝家庭屋頂分布式光伏電站常見(jiàn)問(wèn)題

返回列表 來(lái)源: 發(fā)布日期: 2023.10.12 瀏覽次數(shù):

近年來(lái),分布式光伏電站發(fā)展越來(lái)越好,全國(guó)各地都在陸續(xù)普及,但對(duì)于很多想了解光伏電站經(jīng)常會(huì)問(wèn)我很多問(wèn)題,今天小編給大家整理了一些常見(jiàn)問(wèn)題,供大家參考:

1、裝一套太陽(yáng)光伏系統(tǒng)大概需用花多少錢(qián)?

       答:一般來(lái)說(shuō),家中安裝屋頂光伏發(fā)電系統(tǒng)都在5千瓦至10千瓦的容量,按照現(xiàn)階段光伏發(fā)電系統(tǒng)1w大約在3.8元-4元左右,加入安裝一套10千瓦的光伏電站,大概需要3.8-4萬(wàn)左右。

2、自己家想安裝光伏發(fā)電系統(tǒng)需要做那些準(zhǔn)備?

       答:需要采集一些基本資料,包括太陽(yáng)光照資源、建筑類(lèi)型(民房or商品樓)、屋面結(jié)構(gòu)、房頂占地面、月用電量等。依據(jù)上述信息內(nèi)容,我們會(huì)為你設(shè)計(jì)一套最經(jīng)濟(jì)適用的系統(tǒng)方案,以達(dá)到利益最大化。

3、商品樓能夠安裝屋頂光伏發(fā)電系統(tǒng)嗎?

       答:商品樓是可以安裝的,但需向單元樓住戶(hù)居民和物業(yè)公司詳細(xì)說(shuō)明情況,申請(qǐng)表需用住戶(hù)居民簽字和物業(yè)公司蓋章,成為并網(wǎng)申請(qǐng)辦理的資料存檔。這種情況比較復(fù)雜,涉及屋頂產(chǎn)權(quán)問(wèn)題,如果物業(yè)戶(hù)主都同意那就沒(méi)有問(wèn)題。

4、太陽(yáng)能發(fā)電對(duì)電壓有影響嗎,是否會(huì)影響家電的使用?

       答:分布式光伏發(fā)電系統(tǒng)因功率較小,對(duì)電壓的影響根本感覺(jué)不到。再者,逆變器的功能是將光伏電池發(fā)的直流低壓電轉(zhuǎn)換為220V/380V民用電,而光伏專(zhuān)用逆變器本身就具有智能調(diào)節(jié)電壓的功能,因此光伏電使用起來(lái)同電網(wǎng)電沒(méi)有區(qū)別,不會(huì)影響家用電器的使用。

5、使用了太陽(yáng)能發(fā)電,當(dāng)電網(wǎng)停電時(shí)我們還會(huì)有電嗎?

       答:沒(méi)有。當(dāng)電網(wǎng)停電,并網(wǎng)發(fā)電系統(tǒng)停止工作(如電網(wǎng)維護(hù)光伏繼續(xù)工作會(huì)造成電網(wǎng)事故)。假若需用在此情況下自發(fā)自用,您能夠 選擇額外加裝一個(gè)蓄電池等裝置。現(xiàn)階段蓄電池價(jià)格較高且壽命較短(5年),一般來(lái)說(shuō)不建議安裝。

6、工廠(chǎng)房頂并不是我的,請(qǐng)問(wèn)一下我能安裝光伏電站嗎?

       答:可以安裝,但需通過(guò)和房主協(xié)商租用房頂來(lái)獲得房頂?shù)氖褂脵?quán),之后再建發(fā)電站,這樣做的話(huà),你就是合法的發(fā)電站擁有人了。假若有必要,發(fā)電站也可以搬家的。

7、一個(gè)光伏電站多少年可以回本?

       答:從長(zhǎng)久看來(lái),太陽(yáng)能發(fā)電的收益是很客觀(guān)的?,F(xiàn)階段國(guó)家和政府部門(mén)都在積極支持太陽(yáng)能發(fā)電,有非常好的補(bǔ)貼政策優(yōu)惠,一般來(lái)說(shuō)家用的在5-6年會(huì)完全收回成本費(fèi)。而太陽(yáng)能組件使用壽命的情況為25年,成本費(fèi)收回后就是收益。

8、光伏發(fā)電系統(tǒng)的穩(wěn)定性怎樣,是否會(huì)過(guò)幾年就不行了?

       答:建議選擇大品牌的組件,一般來(lái)說(shuō)都他們都通過(guò)全球各地的權(quán)威檢測(cè)認(rèn)證,通過(guò)了抗鹽霧和氨腐蝕測(cè)試,且具有優(yōu)秀的弱光環(huán)境光伏性能。組件使用25年后的光伏性能還能保持80%以上。

9、屋頂光伏發(fā)電系統(tǒng)安裝對(duì)周?chē)h(huán)境有什么要求?

       答:光伏發(fā)電系統(tǒng)周?chē)写蟮姆蹓m污染源,風(fēng)沙較大,濃煙多等影響太陽(yáng)光照的使用環(huán)境也將導(dǎo)致發(fā)電能力下降。需要清潔

10、冬季天氣冷時(shí),是否會(huì)電力不足?如何解決?

       答:家用光伏發(fā)電的發(fā)電能力的確受到氣溫影響,但影響特別小,直接影響發(fā)電能力的關(guān)鍵因素是輻照強(qiáng)度和日照時(shí)長(zhǎng)及其太陽(yáng)電池組件的環(huán)境溫度。冬季的時(shí)候,氣溫比較低,日照時(shí)長(zhǎng)會(huì)短,因此一般來(lái)說(shuō)發(fā)電能力較夏天會(huì)少,這也是正?,F(xiàn)象。

11、光伏發(fā)電系統(tǒng)的發(fā)電能力和并網(wǎng)的上網(wǎng)電量能夠監(jiān)控嗎?

       答:一般來(lái)說(shuō)家用光伏發(fā)電中的逆變器具有監(jiān)控功能,能夠 對(duì)系統(tǒng)的發(fā)電能力達(dá)到在線(xiàn)監(jiān)測(cè),另外監(jiān)測(cè)系統(tǒng)還可對(duì)關(guān)鍵設(shè)備參數(shù)、電能質(zhì)量、環(huán)境參數(shù)等達(dá)到在線(xiàn)監(jiān)測(cè)。并網(wǎng)的上網(wǎng)電量主要是通過(guò)在并網(wǎng)點(diǎn)安裝經(jīng)過(guò)當(dāng)?shù)仉娏Σ块T(mén)認(rèn)可的電能計(jì)量表來(lái)進(jìn)行監(jiān)控。

12、什么是“自發(fā)自用,余電上網(wǎng)”?

       答:自發(fā)自用,余電上網(wǎng)是指光伏發(fā)電系統(tǒng)所發(fā)電力一部分由用戶(hù)自個(gè)使用,多余電量接入電網(wǎng)賣(mài)給電網(wǎng)公司。結(jié)算依據(jù)按照并網(wǎng)時(shí)安裝在用戶(hù)側(cè)的雙向計(jì)量表進(jìn)行計(jì)量。

In recent years, the development of distributed photovoltaic power plants has been getting better and better, and they have been gradually popularized throughout the country. However, for many people who want to understand photovoltaic power plants, they often ask me many questions. Today, the editor has compiled some common questions for everyone's reference:
1. How much does it cost to install a solar photovoltaic system?
Answer: Generally speaking, installing a rooftop photovoltaic power generation system at home has a capacity of 5 to 10 kilowatts. According to the current photovoltaic power generation system, the cost of 1 kilowatt is about 3.8-4 yuan. Adding a 10 kilowatt photovoltaic power station to the installation would require approximately 38000 to 40000 yuan.
2. What preparations do I need to make to install a photovoltaic power generation system in my home?
Answer: It is necessary to collect some basic information, including solar radiation resources, building type (residential or commercial buildings), roof structure, roof area, monthly electricity consumption, etc. Based on the above information, we will design the most economical and applicable system solution for you to achieve maximum benefits.
3. Can a rooftop photovoltaic power generation system be installed in a commercial building?
Answer: Commercial buildings can be installed, but detailed information needs to be provided to the residents of the unit building and the property management company. The application form needs to be signed by the residents and stamped by the property management company, which will be archived as the information for grid connection application processing. This situation is quite complex and involves the issue of roof property rights. If all property owners agree, then there is no problem.
4. Does solar power generation have an impact on voltage and will it affect the use of household appliances?
Answer: Distributed photovoltaic power generation systems, due to their low power, have no noticeable impact on voltage. Furthermore, the function of the inverter is to convert the DC low voltage generated by the photovoltaic battery into 220V/380V household electricity. The photovoltaic dedicated inverter itself has the function of intelligent voltage regulation, so the use of photovoltaic electricity is no different from that of grid electricity and will not affect the use of household appliances.
5. When solar power is used for power generation, will we still have electricity when the power grid goes out?
Answer: No. When the power grid is cut off, the grid connected power generation system stops working (such as maintaining the grid and continuing to operate the photovoltaic system, which can cause grid accidents). If you need to use it spontaneously in this situation, you can choose to install an additional device such as a battery. At present, the price of batteries is relatively high and their lifespan is relatively short (5 years), so it is generally not recommended to install them.
6. The factory roof is not mine. Can I install a photovoltaic power plant?
Answer: It can be installed, but you need to negotiate with the homeowner to rent the roof to obtain the right to use it, and then build a power station. By doing so, you are the legal owner of the power station. If necessary, the power station can also be moved.
