太陽電池(PV)模組信賴度檢驗 PV Module Reliability Scorecard 2014
出版日期: 2014年07月17日 內容資訊: 英文
簡介

現在的太陽光發電設備有2/3都是這3年設置的。預計到2020年太陽電池設置量將增加4倍、設備容量從2013年的128.3GW擴大至2020年528.1GW。受到太陽光發電計畫急速擴大影響、整體產品品質相對讓人擔心。對於模組信賴度的相關問題與誤解狀態持續。目前製品壽命結束前的發電量依然不明、供應商並不公開模組長期的信賴度相關資料。

本報告針對太陽光發電模組長期信賴性--製品生命發電量與品質惡化的狀況--進行分析、並提供詳細檢驗方法說明、主要供應商模組信賴性的檢驗結果與解釋、現場適用可能情報。

目錄

Two-thirds of today's cumulative solar capacity has been installed within the last three years, and PV installations are forecasted to quadruple by the end of the decade, growing from 128.3 GW at the end of 2013 to 528.1 GW by the end of 2020. Against this backdrop of strong demand, there is growing concern that systemic quality issues will affect an exponentially increasing proportion of PV projects. Yet, so far, the extent of the module reliability problem has been largely misinterpreted and ill-understood. With full-life field data on today's products years away, and without access to publicly available data comparing long-term module reliability by vendor, how can buyers and investors factor quality into their procurement discussions?

The PV Module Reliability Scorecard aims to address this critical problem. The Scorecard defines a reliable module as one which can deliver its promised and guaranteed energy yield over its lifetime. With its supplier-specific performance analysis, the Scorecard is another tool for investors' and developers' quality-backed procurement strategies.
