目前在新能源領(lǐng)域，光伏電站已經(jīng)是很多大企業(yè)的首選，利用太陽能轉(zhuǎn)化成的電，可以直接每年為企業(yè)剩下省下一大筆的電費(fèi)。其中光伏電站還分為光伏離網(wǎng)系統(tǒng)和光伏并網(wǎng)系統(tǒng)。兩套系統(tǒng)一字之差，價(jià)格卻差了數(shù)千。
At present, in the field of new energy, solar power stations have become the first choice of many large enterprises. The electricity converted from solar energy can directly save a large amount of electricity bills for the rest of the enterprise every year. Solar power systems are also divided into solar off-grid system and solar grid-connected system. The difference between the two systems is one word, but the price is thousands.
光伏離網(wǎng)系統(tǒng)指的是，通過太陽能轉(zhuǎn)化的電轉(zhuǎn)存在蓄電池里。目前蓄電池有鉛酸電池、鋰電池，在離網(wǎng)系統(tǒng)它占據(jù)了發(fā)電系統(tǒng)的30%-50%的成本。從市場(chǎng)的離網(wǎng)系統(tǒng)所用電池來看，鉛酸蓄電池一般都在3年左右，鋰電池壽命在6、7年，隨著高效電池技術(shù)的更新，蓄電池的壽命在未來會(huì)逐漸增加。離網(wǎng)逆變器一般有四級(jí)結(jié)構(gòu)，包括控制器、升壓、逆變、隔離。
Solar off-grid system means that the electricity converted by solar energy is stored in the battery. At present, there are lead-acid batteries and lithium batteries, which account for 30% - 50% of the cost of the power generation system in the off-grid system. From the perspective of batteries used in the off-grid system of the market, lead-acid batteries generally have a life of about 3 years, and lithium batteries have a life of 6 or 7 years. With the update of high-efficiency battery technology, the life of batteries will gradually increase in the future. Off-grid inverter generally has four-stage structure, including controller, boost, inverter and isolation.
光伏并網(wǎng)系統(tǒng)指的是，通過太陽能轉(zhuǎn)化的電，直接接入電網(wǎng)，需要配備雙向電表，并網(wǎng)系統(tǒng)所發(fā)的電是交流電，可以直接用于家庭的負(fù)載，多余的電還可以賣入電網(wǎng)。但是并網(wǎng)逆變器一般是升壓和逆變兩級(jí)結(jié)構(gòu)。
Solar grid-connected system means that the electricity converted by solar energy can be directly connected to the grid, and two-way electricity meters need to be equipped. The electricity generated by the grid-connected system is AC, which can be directly used for household load, and the surplus electricity can also be sold into the grid. However, the grid-connected inverter is generally a two-stage structure of boost and inverter.
從構(gòu)成、成本、效率綜合來看，光伏離網(wǎng)系統(tǒng)成本比較高，而且會(huì)盈余電量無法儲(chǔ)存，因此離網(wǎng)發(fā)電系統(tǒng)是專門針對(duì)無電網(wǎng)地區(qū)或經(jīng)常停電地區(qū)場(chǎng)所使用的。
From the perspective of composition, cost and efficiency, the PV off-grid system is relatively high in cost, and the surplus power cannot be stored. Therefore, the off-grid power generation system is specially designed for use in areas without power grid or areas with frequent power outages.
隨著太陽能支架系統(tǒng)技術(shù)的成熟，產(chǎn)品質(zhì)量的提升，圍繞離網(wǎng)與并網(wǎng)的應(yīng)用也會(huì)越來越多，相信在不久的將來將會(huì)有更多的企業(yè)工廠因此獲益，也助力了全球的綠色能源可持續(xù)發(fā)展。
With the maturity of solar mounting system technology and the improvement of product quality, there will be more and more applications around off-grid and grid-connected. It is believed that more enterprises and factories will benefit from this in the near future, which also contributes to the sustainable development of global green energy.
