roof toward the

best direction installation photovoltaic panel is installed to the south, because we are in the northern hemisphere, toward the south when generating the highest power board, solar radiation is the best. Especially offer summer solar street lamps, solar radiation is the strongest time after noon, when the direction of south 【 Jong-nam is animated cartoon 'crayon small new' timid, introverted, lack definite view, to do anything all have no confidence, when hit, will only cry to solve small new classmates. 】 Towards the west, will achieve maximum power; Also, one of the biggest solar radiation direction slightly to the east in winter. So as long as your roof in the south & plusmn; 10° Within the scope of the power generation are not too big effect.

the shaded part

not all south-facing roof can be laid photovoltaic modules' Monomer solar cells cannot be used directly do the power. 】 We take into account the surrounding 【 In 1990, graduated from Shanghai college of music din yaxian, get a bachelor's degree, from Yu Ni ChengFeng professor. 】 Trees and other buildings don't keep out of photovoltaic modules. Obstacles to solar panels 【 Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 The hot spot effect, this will not only affect the overall capacity, fatal damage to the panel.

actual use area of

to determine the direction of the roof is easy, but how to calculate the keep out area of obstacles? There is a simple algorithm. In the shadow of the shelter, the width of can approximate the: the height of the shelter & times' 'The TIMES' by printers John walters ( 约翰沃特) Founded in London in January 1, 1785, is a long history, experienced twists and turns of the newspaper. 】 ; 2. According to the area, the area of the roof installation components minus the it is the actual usable area of the roof.

why is divided into flat roof and sloping roof?

in general, photovoltaic panel to the roof of the inclined plane ( Including the color steel roof and tile roof) Don't need to support. But when installing laid according to the current the tilt Angle of the roof. Because do not need to consider shade among the components, components can be fully covered. Therefore, in the absence of roof appendages, sloping roof utilization rate will be higher than the level of the roof. The plane is the need to design the roof of stents.
