■太陽光発電: Erbsモデルによる斜面日射量の推定
(2011年6月〜2012年2月)
広島地方気象台における2011年6月から2012年2月までの、日別の全天日射量と斜面日射量の関係を計算した結果を示します。
・計算式は−> Erbs&METPV-3 計算式
・albedo = 0.2、屋根傾斜 28.8°、方位 25°(ほぼ南南西)
・斜面E: Erbsモデルにより計算された斜面日射量
・斜面M: METPV-3モデルにより計算された斜面日射量
・斜面E/全天: 斜面E/ 全天日射量の比
・斜面M/全天: 斜面M/ 全天日射量の比
・斜面M/斜面E: 斜面M/ 斜面Eの比
・日射量の単位は kWh/m2 (ikWh = 3.6MJ)
ErbsモデルとMETPV-3モデルによる斜面日射量の値には大きな違いはありません。

(注)ErbsモデルおよびMETPV-3モデルにおける斜面日射量の計算式では、夕方など高度角0度付近で
値に乱れが出ることがあるため、後日計算式を修正した。
上表の値は修正前の値であるが、月合計値の誤差は高々0.5%程度である。
