発電量を最大化させるために、日射量が最も多い南側に設置することをオススメいたします。
東側や西側も、発電量は南側に設置した場合の約85%となるものの、十分発電に適した方位です。なお、屋根に設置するときの傾斜は、その地点の緯度角(東京の場合30°~35°)が理想的ですが、基本的に屋根の勾配に準じて設置いたします。
In order to maximize the amount of power generation, we recommend that you install it on the south side where the amount of solar radiation is the largest.
Even on the east side and the west side, although the amount of power generation is still about 85% of the case it is installed on the south side, it is a direction suitable enough for power generation.
The ideal angle for the panel to be installed on the roof to maximize the generating power is supposed to be the same as the latitude angle of that point (30 °to 35 ° in Tokyo) , however basically it will be installed according to the gradient of the roof.
