What 太陽光発電の設計・施工 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（売電）「全量売電型」に分類される。
設計においては太陽光発電設置者が設置する目的と予算などのニーズに応えつつ、最適な発電性能と安全性の高い発電所とするべく、電気設計、構造設計を行う。架台、基礎、地盤強度などは、「日本産業規格(JIS)」、「電気設備に関する技術基準」などの基準や関係法規・法令に則した設計を行う必要がある。守らなければならない基準や法規・法令は、設置する地域や場所など、設置環境によって異なる。
施工においては、設計された発電所の建設を進めるために日程、工程、安全、予算を管理していく。建設にあたっては設計を忠実に守って行うだけでなく作業を進めていく上で変化する近隣や設置環境を考慮し、設計通りに進まないことが予測される、または進まなくなった場合に設計の変更を提言・実行する必要がある。
設計、施工いずれにおいても、設置者の目的と予算に則しつつも、太陽光発電所は20年以上の長期間にわたって稼働し続けるものであることを念頭に、安全面、耐久性を最優先事項として取り組む必要がある。

Projected pay for 太陽光発電の設計・施工 (3, 5 and 10 years)est.
Today ¥6.25M → in 3 years ¥6.70M → in 5 years ¥7.01M → in 10 years ¥7.87M (10-year range ¥6.77M–¥9.13M). The model assumes pay growth of +2.3% per year.
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 →
Outlook score for 太陽光発電の設計・施工
Each component is a percentile rank among all occupations in the same country (0–100). Weights: labor demand 25, wage momentum / openings 15, pay level 15, AI resistance 25, aging workforce 10 (Japan only), entry barrier 10.
Will AI replace 太陽光発電の設計・施工? 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 →
Labor demand for 太陽光発電の設計・施工
A ratio above 1.0 means there are more job openings than applicants (a labor shortage). The 5- and 10-year figures are estimates from the openings ratio, wage momentum and AI replacement risk.
