＜PCS再功率化的瓶頸＞
固定價格收購制度（FIT）實施已逾10年，國內太陽光發電廠的集中式PCS正逐漸老化。集中式PCS存在單一設備故障可能導致整個發電廠停運的風險，為了解決此問題，更換為分散式PCS的再功率化正受到關注，成為一個有效的選擇。
然而，阻礙再功率化執行的最大瓶頸並非PCS本體的更換。隨著PCS的轉換，連接箱、集電箱的增設以及DC/AC電纜的重新配線等周邊設備也將產生廣泛的變更。這些需要分別向PCS製造商、材料採購商、施工業者下單並進行協調，其繁瑣的流程以及協調期間累積的發電損失，一直是影響營運商決策的因素。
＜GBP的對應體系＞
針對PCS再功率化的這些課題，GBP提供以下一站式服務：
◆統一窗口，減少手續
將從材料採購到施工完成的窗口集中於GBP，以減少客戶在業者間協調的負擔。
◆周邊設備採購至施工的一貫作業
統籌處理PCS更換所伴隨的周邊設備對應，包括連接箱、集電箱的提供與安裝工程，以及DC/AC電纜的配線工程，以最小化發電損失。
＜1.7MW發電廠的PCS再功率化實績＞
GBP曾在一座1.7MW的太陽光發電廠，成功地將3台集中式PCS更換為24台分散式PCS的一站式服務。除了PCS本體的更換，更從連接箱、集電箱的提供到施工、電纜配線工程都進行了一貫作業，實現了工期縮短及發電損失的最小化。

＜迎接再功率化需求的本格化＞
FIT制度實施已逾10年，未來面臨設備整體老化（不僅是PCS，還包括太陽光面板、連接箱、集電箱等）的發電廠預計將持續增加。GBP將以其能獨立完成從設備材料採購到施工、營運維護（O&M）的一站式服務體系為優勢，為減輕營運商負擔及確保發電廠長期穩定運行做出貢獻。
我們不僅能提供PCS更新服務，更能從著眼於設備整體優化的再功率化考量階段就提供對應。歡迎隨時洽詢。
常見問題
What is PCS repowering?
PCS repowering refers to the process of replacing or upgrading the Power Conditioning System (PCS) in a solar power plant. This is often done to replace aging equipment, improve efficiency, or adapt to new technological standards.
Why is PCS repowering necessary?
Many solar power plants installed over 10 years ago under the Feed-in Tariff (FIT) system are now facing aging equipment, particularly central-type PCS. Repowering is necessary to maintain operational efficiency, prevent failures, and ensure continued power generation.
What are the main challenges in PCS repowering?
The primary challenges include the extensive work required for peripheral equipment such as junction boxes, collector boxes, and DC/AC cable re-wiring, in addition to the PCS unit replacement itself. Coordinating with multiple contractors for these tasks can be complex, time-consuming, and lead to power generation losses during the transition.
How does GBP's one-stop solution address these challenges?
GBP offers a comprehensive service that handles everything from component procurement to the installation of peripheral equipment and final construction. By acting as a single point of contact, GBP simplifies coordination, reduces the burden on operators, shortens construction periods, and minimizes power generation loss.
What kind of projects has GBP handled?
GBP has experience in repowering projects, including a case where they handled the transition of a 1.7MW solar power plant from three central-type PCS units to 24 distributed-type PCS units, managing all aspects from component supply to wiring construction.
