利用環境因子校正太陽能板最佳傾斜角之研究
Using Enviroment Parament to Adjust the Title Angle of Solar Panels for Improving The Energy Efficiency
摘要
太陽運行相對高度角位置一樣，地球繞行太陽的方位角來計算台灣主要的四季方位角，並以夏至為高度角的最高點 89.5° 為基準，再以春分及秋分的高度角 66°為輔，量測相對應的高度角一樣、結果一樣時，所以以高度角為參考來量測合乎理論。因此本研究是根據太陽高度角數學運算方式計算及相關氣象資料，進而利用程式在各方位與角度計算模擬的方式外，另加強固定式地在不同環境實地量測太陽能角度受繞射影響以應證理論數據與實測數據的正確性。實驗過程中，在空曠的操場跟屋頂無遮蔽建築物的測量下，峰值誤差為 1° ~ 4° 之間。而在簡單較低建築遮蔽物的情況下，峰值誤差為 8°~11° 之間。但是在複雜較高建築遮蔽物的情況下，峰值誤差為 14° ~ 21° 之間，誤差甚大。經實驗結果證實，在周圍有建築遮蔽物時，太陽能板安裝角度需考慮一年四季的太陽運行角度及散射影響，才有有效的利用太陽能，以致於提高發電效能。

The sun moves the height above airport angular position to be same, the Earth detours sun's azimuth to calculate the Taiwan main four seasons azimuth, and take the summer solstice as the elevation angle peak 89.5° is the datum, again take vernal equinox and Autumnal equinox elevation angle 66° as auxiliary, the gauging corresponds when elevation angle same, result same, therefore gauges take the elevation angle as the reference conforms with the theory.Therefore this research is according to the solar elevation angle mathematics operation way computation and the related meteorological data, then the use formula in various positions and outside the angle computation simulation way, adds seperately the firm format to gauge the solar energy angle in the different environment to meet on the spot the diffraction influence the card gross data and the measured data accuracy.In the experimental process, non-camouflages the building in the spacious drill ground with the roof under the survey, peak value error for 1° ~ 4° between.But in simple low construction obstacles situation, peak value error for 8°~11° between.But in the complex high construction obstacles situation, the peak value error for 14° ~ 21° between, the error is really big.Confirmed after the experimental result, has the construction obstacles when periphery, the solar energy board installs the angle to have to consider the throughout the year solar movement angle and the scattering influence, only then has the effective use solar energy, enhancement electricity generation potency.
