目前在新能源領域，光伏電站已經是很多大企業的首選，利用太陽能轉化成的電，可以直接每年為企業剩下省下一大筆的電費。其中光伏電站還分為光伏離網系統和光伏并網系統。兩套系統一字之差，價格卻差了數千。
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.
光伏離網系統指的是，通過太陽能轉化的電轉存在蓄電池里。目前蓄電池有鉛酸電池、鋰電池，在離網系統它占據了發電系統的30%-50%的成本。從市場的離網系統所用電池來看，鉛酸蓄電池一般都在3年左右，鋰電池壽命在6、7年，隨著高效電池技術的更新，蓄電池的壽命在未來會逐漸增加。離網逆變器一般有四級結構，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.
光伏并網系統指的是，通過太陽能轉化的電，直接接入電網，需要配備雙向電表，并網系統所發的電是交流電，可以直接用于家庭的負載，多余的電還可以賣入電網。但是并網逆變器一般是升壓和逆變兩級結構。
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.
從構成、成本、效率綜合來看，光伏離網系統成本比較高，而且會盈余電量無法儲存，因此離網發電系統是專門針對無電網地區或經常停電地區場所使用的。
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技術的成熟，產品質量的提升，圍繞離網與并網的應用也會越來越多，相信在不久的將來將會有更多的企業工廠因此獲益，也助力了全球的綠色能源可持續發展。
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.
