Here are a few options for a description for the WordPress post tag “太陽光” (Sunlight/Solar Energy) in Traditional Chinese, catering to different levels of detail and context:

**Option 1: Concise and General**

* **Description:** 關於太陽能光電技術、能源應用與環境友善的相關文章。 (Related articles focused on solar photovoltaic technology, energy applications, and environmental friendliness.)

**Option 2: More Specific and Informative**

* **Description:** 探索太陽光的奧秘，涵蓋太陽能板、光伏系統、能源儲存、綠色能源政策與永續發展的相關資訊。 (Explore the mysteries of sunlight, covering information on solar panels, photovoltaic systems, energy storage, green energy policies, and sustainable development.)

**Key things to consider when choosing your description:**

* **Target Audience:** Who are you writing for? Are they laypeople, industry professionals, or somewhere in between?
* **Content of your Posts:** What kind of articles do you plan to tag with “太陽光”? Will they be broad in scope, or focus on specific aspects of solar energy?

* **Keywords:** Include relevant keywords to help with SEO.

I would generally recommend **Option 2 or 3** as they offer a good balance of information and appeal to a broad audience. Select the one that best reflects the content of your blog. Remember to also set a “Slug” for your tag (e.g., ‘tai-yang-guang’) when setting it up in Wordpress.
