DRAFT — outline only. Do not publish until the figures below are verified. Keep this guide inactive until it is written.
Angle: Explain the counter-intuitive point that extreme heat slightly reduces panel efficiency.
This guide must answer: - Why do panels lose efficiency as they get hotter? - How much output is lost to heat derating in an Indian summer? - Does more sun still mean more generation overall in summer? - Does mounting/airflow reduce the effect?
Writing rules: answer the question in the first two sentences, put a real number in the opening paragraph, name the specific city or DISCOM where the answer varies, and link to two related guides and the relevant category page.
Verify before publishing: Typical temperature-coefficient impact; keep technical claims sourced.
