What 太陽光発電のメンテナンス do
An English description is being prepared. Japanese description:
太陽光発電には発電した電気を自らが使用する「自家消費型」と、事業や投資などを目的に発電した電気をすべて電力会社に売る「全量売電型」に分類される。さらに「自家消費型」は発電した電気をすべて消費する「完全自家消費型」と、使用せずに余った電気は電力会社に売る「余剰売電型」に分かれる。
メンテナンスの仕事は、太陽光発電設備が稼働するのに支障が出るような不具合の発生を防止するために、実際に太陽電光パネル、架台、電気設備の設置状況や固定状況、破損箇所などを確認する。パワーコンディショナ接続箱については電圧を測定し、正常に作動しているかの確認も行う。
リアルタイムで記録される発電状況の遠隔監視も行う。パワーコンディショナの停止や自然災害によるトラブルなど、発電設備の不具合を感知した際には、現場に駆けつけて原因の調査、一次対応などを行う。
発電設備が地上に設置されているのか、屋根に設置されているのかなどの立地条件や周辺環境、気候などにより作業内容は異なる。パネルの洗浄、雑草対策、フェンスの設置・修理など発電設備周辺の管理もメンテナンスの一環である。

What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (the job-openings-to-applicants ratio), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →

Will AI replace 太陽光発電のメンテナンス? AI replacement risk
How AI is changing this job
A written analysis for this occupation is being prepared.
AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
