Mary decides to put solar panels on the roof. The solar panels are fitted to both sides of the roof.
Each panel is 1.9 m long and 0.8 m wide. All the panels must be arranged in uniform rows, with the shorter edge of each panel parallel to AB or AC. The length AB is approximately 2.8m. The length AC is approximately 2.6m. The length BD is approximately 12m. Each panel must be at least 0.4 m from the edge of the roof and the top of the roof, AF. (Diagram not to scale)
(1) 請問在全部的屋頂上最多能鋪設幾片完整的太陽能板? [3 分]
Find the maximum number of complete panels that can be fitted to the whole roof.
參考答案與給分標準:
12−2(0.4)
1.9
2.8−2(0.4)
0.8 OR 2.6−2(0.4)
0.8
20
Note: Award (M1) for correct calculation of the number of panels on the long side.正確計算長邊太陽能板數量時給予 M1 (M1: 方法/列式正確 1 分)
Note: Award point for correct calculation of the number of panels on either short side with no further incorrect working.
正確計算另一邊的太陽能板數量並且沒有其他錯誤時給予 M1 (M1: 方法/列式正確 1

C F
D D
(2) 瑪莉估計出太陽能板覆蓋的面積約為 20 平方公尺,請找出該估計值之誤差百分比為 何?(四捨五入取到小數點後一位) [3 分]
Mary estimates that the solar panels will cover an area of 20 𝑚2. Find the percentage error in her estimate. [Giving an answer to 1 decimal place.]
參考答案與給分標準:
20 ×1.9× 0.8(= 30.4)
20 30.4 100%
30.4
−
4.6(%) (4.60526 (%))
Note: Award (M1) for their 20 1.9 0.8 or 30.4 seen. Follow through from their 20 in part (1).
Award (M0) if their 20 is not an integer.
根據前一小題的答案寫出算式 20 1.9 0.8 或直接寫出 30.4 給予 M1 (M1: 方法正確 1 分),但是若前一小題的答案不是寫整數時給予 M0(M0:方法正確但給 0 分)
Note: Award (M1) for correct substitution of their 30.4 into the percentage error formula.
Their 30.4 must be exact.
Accept a method in two steps where “ 100 ” is implicit from their answer. The second (M1) is contingent on the first (M1) being awarded, eg do not award (M0)(M1)(A0).
正確將第一部分得到的答案代入誤差公式時給予 M1
(
M1:
方法正確 1 分)
,他們的「30.4」必須是前一部分真正得出的值。可接受將百分比分兩階段寫出,其中(×100)隱 含在答案中。
第二部分的方法使用得分 M1
(
M1:
方法正確 1 分)
取決於第一部份的方法使用得分 M1(
M1:
方法正確 1 分)
,亦即第一部分方法使用不正確則後續不給分。Note: Follow through from their answer to part (1). Percentage sign is not required.
根據前述計算得出的答案而得給予A1(A1:正確答案 1 分),%的符號不要求。
(3) 瑪莉在研究太陽能板排列方法時,將長邊與𝐴𝐵或𝐴𝐶平行。[2 分]
請說明新的太陽能板排列方式是否可在屋頂上鋪設更多的太陽能板呢?並驗證你的答案。
Mary investigates arranging the panels, such that the longer edge of each panel is parallel to AB or AC.
State whether this new arrangement will allow Mary to fit more solar panels to the roof.
Justify your answer.
參考答案與給分標準:
1×14(一側屋頂) OR 28 (全部)
No(不能)New arrangement will mean fewer solar panels.
(新的排列方式會得出較少的太陽能板)
Note: Follow through from their maximum number of panels in question 1. Do not award( R0)(A1) 經由與第一小題得出的最大數量比較而得給予 A1(A1:答案正確 1 分)。前一部分推理不正 確不給分 R0 (R0:錯誤推理 0 分)。
Note: Award (R1) for one correct array seen (114 ) or total number of panels (28 ). Working is not required, but award (R0) for incorrect working seen. Correct working is as follows.
(
12−0.80.8
,
2.6−0.81.9
,
2.8−0.81.9
)
Reasoning may compare both sides of the roof or just one side; accept correct comparisons with question1 values. Follow through from their treatment of tolerances in question1.
Award (R0) for any approach with no clearance or for any method which includes further incorrect working.
寫出一側屋頂的數量 14 或全部數量 28 給予(R1)(R1:正確推理 1 分),不要求過程,
但是有錯誤的推理過程時給予 R0(R0:錯誤推理 0 分)。正確的計算過程為
(
12−0.80.8

2.8−0.81.9
)
推理時可以只比較一側屋頂或全部屋頂,以第一小題的答案進行比較也是可接受的。
不清楚的論述方式或任何包含錯誤過程的方法給予 R0(R0:錯誤推理 0 分)
(4) 為了產生足夠的電能,太陽能板上需有許多光電池。光電池能將太陽光轉換成直流電。太陽 光輻射到地球表面的平均強度為 245 (瓦特/公尺2)。在太陽能板上的光電池,以 25%轉換 效率,將太陽光的能量轉換成電能。
問:請預估每片太陽能板所提供的電功率[4 分]
Many photovoltaic cells are needed in solar panels to produce appreciable amounts of electrical power. A photovoltaic cell converts sunlight directly into direct current (DC). The average intensity of solar radiation incident on the Earth surface is 245 W/𝑚2. In an array of photovoltaic cells, solar energy is converted into electrical energy with an efficiency of 25%.
Estimate the electrical power provided of photovoltaic cells on each solar panel.
參考答案:
93.1 W
Note: Identify the power incident on a solar panel is 245×1.6×0.95 W (1)
The electrical power P=0.25×245×1.9×0.8=93.1 W (1)
說明太陽能板接收到的太陽光功率為 245×1.9×0.8 瓦特 (1)
計算電功率 P=0.25×245×1.9×0.8=93.1 瓦特 (1)
