Task 1: The diagram below shows how solar panels can be used to provide electricity for domestic use.

• Introduction：改写题目

  The picture illustrates the process of producing electricity in a home using solar panels.

• Overall：流程共有5个不同的步骤，从太阳能的转化开始。最后两个步骤是家庭用电如何跟外部供电相关联的。

  It is clear that there are five distinct stages in this process, beginning with the capture of energy from sunlight. The final two steps show how domestic electricity is connected to the external power supply.

• Body Paragraph 1 - 数据分组介绍1：步骤1、2、3，太阳能是如何转换成电能供给到房屋中的。

  At the first stage in the process, solar panels on the roof of a normal house take energy from the sun and convert it into DC current. Next, this current is passed to an inverter, which changes it to AC current and regulates the supply of electricity. At stage three, electricity is supplied to the home from an electrical panel.

• Body Paragraph 2 - 数据分组介绍2：步骤4、5，家庭用电如何跟外部供电进行关联。

  At the fourth step shown on the diagram, a utility meter in the home is responsible for sending any extra electric power outside the house into the grid. Finally, if the solar panels do not provide enough energy for the household, electricity will flow from the utility grid into the home through the meter.
