Question: The diagram shows the structure of a solar panel and how it is used.
(IELTS Academic – Week 4, June 2025)
ANSWER (8.0+):
The diagrams present a detailed explanation of how a solar panel is built and how it functions. They illustrate the main parts of the system and demonstrate the process by which solar https://khud.cfga.gov.mn/ energy is utilized to produce either heated air or warm water.
Starting with the first diagram, it outlines the physical structure of a standard solar panel . This includes a transparent glass cover fixed on the top surface, as well as an inlet and outlet pipe https://www.cfga.gov.mn/
installed on opposite ends of the panel.

The second diagram describes how solar energy is absorbed and used to heat air. Sunlight passes through the transparent glass layer and warms the air that flows into the panel through the inlet pipe . As a result, the heated air exits the panel via the outlet pipe , creating a flow of warm air that https://jlp.uap-bd.edu/ can be used externally.
As for the third diagram, it illustrates the process of heating water using the same solar panel. Cold water enters https://auladeidiomas.ulpgc.es/ through the inlet pipe and travels along an ‘S’-shaped pipe located inside the panel. When sunlight reaches the surface of the panel, the water inside the pipe absorbs thermal energy and then leaves the system through the outlet pipe as warm water, ready for https://link.space/@Ovo777loginhttps://museoicticola.uabjb.edu.bo/ practical use .
