Shape, material, and years since construction of photovoltaic generation and roof
“Can the solar photovoltaic system be set up now though my home is old 20 years?”, “Does the roof of my home be for the south, decrease on the day shooting, and isn’t the photovoltaic generation impossible?”, “In [yomune]“, and “Though it is a gable. “, etc.The condition changes in each each house though I want to examine the introduction of the solar photovoltaic system. As a matter of fact, is there an unsuitable condition for the installation?
In the shape of the roof, there are a span roof, [katagyou] roof, a hip roof, a sloping one way only, and a deck. As the material, other metallic [itakawarabou], metallic [yokofu], a harmony tile, a western tile, a monotonous tile, it waterproofs silicon though a lot of one that is is the color best, and there is furthermore a metallic halving, too.
“Roof of the look south” is certainly an ideal for the installation. Variously in the house set up and the gable. the house etc. set up both sides of east and west the look south and the zonal side in [yomune] excluding actually the north side however itIt is general that the zonal side becomes down of 40 percent in 5?15 percent down and facing north when 100 of the decreases in efficiency by the installation azimuth is a look south. Moreover, it is about several percent even though the angle of gradient of the roof that sets up the solar panel according to the shape of the roof changes.
The load is about 15~20 kilograms (There is a difference by the manufacturer. The industrial method changes for the deck) ..drinking a solar panel (..taking off.. [sun] about 1m×1m).. including the installation counter etc. though durability by years since construction comes to be worried, too. Certainly, there is a load to the roof and the load of ginger and the solar photovoltaic system is distributed to the entire roof (Become the roof load of about 300 kilos for the solar water heater ..becoming the object of the comparison well.. ..all sides.. about three meters). Therefore, it seems that there is hardly a problem as long as it is not a house where years since construction and the roof material are old.
It might be good to request the simulation of the amount of power generation and the amount of power saving by shape, the direction of the roof, and the material, and to confirm durability beforehand.
