If you’re DIY-minded, you can build your own solar power system. In some you can even build your own solar panels, although the amount that you can effectively DIY home solar depends on how much you want to power. Making your own solar panel is a time-consuming process and requires some electrical skills. However, it can also be very regarding—leaning to build your own panel is a great way to understand how electricity in generated.

Before you can build your own solar panels, you first need to understand how solar cells generate electricity. Once you’ve bought individual solar cells (they can be purchased online), the basic process for building your own solar panel goes like this: Prepare the backing for your panel. Many DIY solar panel builders prefer to use a wooden board as the base for their solar cells.

You’ll need to drill holes m the board so that the wires for each cell can pass through. Wire your solar cells together. This requires some experience for electrical work. Use a soldering iron (烙铁) to attach wire to the solar cells and then link each of the cells together. Attach cells to your backing. If possible, attach each solar cell to the backing individually. This makes it easier to replace a single cell in the event that becomes damaged or is not operating properly.

At this point you have a functional solar panel that can produce electricity when the sun shines. However, a solar panel by itself is not useful. If you are trying to generate electricity to power devices in your home, you need to pair your panel with inverter (转换器) that will turn direct current (DC) power from the sun into alternating current (AC) power used in most electronic devices.

C. To attach cells to the backing tightly.

D. To substitute damaged cells easily.

4.What can be inferred from the text?

B. A functional solar panel can give power to your home devices directly.
