1
Let's examine another key term in the design parameters for the racking, and that is minimum clearance and maximum height.
2
You can see here what those parameters look like for each of our two main racking types.
3
With fixed tilt, it's a pretty easy concept to grasp since everything stays put.
4
For tracker systems, however, you have a moving part
5
which both decreases the clearance and increases the system height as it moves throughout its daily cycle.
6
So now you'll need to factor in the height of the system at its maximum rotation or height.
7
One key way that ground clearance and maximum height are varied or adjusted is by changing what's called post reveal.
8
Reveal is the distance from the ground to the top of the post, and it's a key consideration for racking design.
9
Let's start with clearance.
10
Typically, the minimum clearance will be determined by the project owner if they have a technical specification.
11
And then designers also need to look at maximum snow depths
12
and vegetation control plans to determine how much clearance the racking needs to maintain above grade at maximum tilt.
13
Note, I have a tracker system shown here, but these factors apply for fixed tilt as well
14
when looking at a maximum height there's also the wind loading to consider as modules are tilted higher
15
and higher or are further off the ground they're exposed to higher wind loading
16
and this may either cause foundations to be deeper or heavier steel
17
or may just simply exceed the mechanical rating of the modules
18
or racking this is really a limitation that will be calculated by the racking vendor
19
but just something to be aware of especially in areas with high wind speeds
20
to determine the required clearance
21
and maximum height of a tracker system you'll need to know
22
the tracker rotation angle tracker rotation angles vary by manufacturer
23
and are typically listed on the data sheets for the most part these will be between 45 degrees
24
and 60 degrees with some manufacturers offering special options for higher angles
25
for instance to stow at 75 degrees angle to avoid perpendicular impacts of hail, which is pretty cool.
26
Remember
27
that zoning regulations usually restrict the maximum height of a PV array based on the height of the system at maximum tilt.
28
Zoning boards are fairly attuned to system height
29
and may want a graphic like the one a few slides ago
30
that shows the maximum height of the tractor system at full tilt.

推薦影片

為何這段影片是絕佳的口語練習素材?

這段關於太陽能支架設計的影片,語速適中且邏輯清晰,非常適合英語影子跟讀練習。內容涉及專業術語(如“minimum clearance”“post reveal”)與日常表達的結合,既能鍛鍊學習者對複雜概念的理解,又能提升口語流暢度。其講解式的語氣貼近真實交流場景,有助於學習者掌握自然的語調和重音,是看YouTube學英語的優質素材。

拆解地道表達,學習自然口語

1. “You can see here what those parameters look like for each of our two main racking types.” 此句中“you can see here”是典型的口語引導語,自然引出話題,避免表達生硬。
2. “For tracker systems, however, you have a moving part which both decreases the clearance and increases the system height as it moves throughout its daily cycle.” 句中“however”的使用巧妙轉折,“as it moves throughout its daily cycle”則用簡潔的時間狀語從句說明動態過程,體現口語表達的連貫性。
3. “Zoning boards are fairly attuned to system height and may want a graphic like the one a few slides ago that shows the maximum height of the tractor system at full tilt.” 其中“are fairly attuned to”意為“對……相當敏感”,是地道的書面口語混用表達,比“care about”更精準,展現語言的豐富性。

影子跟讀練習步驟,提升口語能力

採用shadow speak訓練法,按照以下步驟練習:
1. 播放影片,逐句暫停,跟讀並錄音。重點模仿“however”“for instance”等連線詞的語調,以及“maximum rotation”“mechanical rating”等專業術語的發音。
2. 對比錄音與原影片,注意句子的停頓和重音(如“critical design parameters”中“critical”和“parameters”的重音)。
3. 連貫播放影片,進行無暫停影子跟讀,訓練反應速度和口語流暢度。
堅持每日練習15分鐘,可有效提升英語口語的自然度和準確性。

什麼是跟讀法?

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧,最初開發用於專業口譯員的培訓,並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大:您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同,跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性,語調,節奏,連讀,聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
