Solar power despite snowfall

While the crystalline modul delivers even not enough voltage delivers the Three layer amorphous from Unisolar still 32,6 mA charge current. 398 mW from 0,5m².

Crystalline PV, no power, voltage not enough     ( 2005-12-06 9:00 )
Uni-Solar: 795 mW per m²
Photovoltaic
Different view points about photovoltaic from our different technical magazines as wide outstretched information about electric power from light.




  Planning an one family house


I started 2004 with the requirements specifications for the planned construction. One year later how the requirements specifications develops to plans.

South side with sunny sight
Who gets the south side? Human or solar equipment? Against most rigid solar architecture, not the solar equipment but the human inhabitants.


Photovoltaic compare
A 20 Watt crystalline silicon photovoltaic from 1998 vs 3 layer amorphous from Uni-Solar. Under dense clouds, the crystalline PV has no chance.


Photovoltaic east west roof
The requirement for a flat inclining towards east and west roof influences the decision for the photovoltaic.At unfavorable alignment is amorphous silicon from Unisolar favorite.


Under the staircase Under the staircase
A rectilinear staircase makes it possible to place below some cupboards. Since the staircase does not count at the living space, it makes more storage capacity possible.


Wardrobe below staircase Wardrobe below staircase
One movement and the wardrobe glides out below the staricase. In many prefabricated component houses are angled staircases where this is impossible.


Shoe box below staricase Shoe box below staricase
The next furniture below the staricase is for shoes, because they need less height than the wardrobe. Passionate optimal space usage.




It snows - anyway electric power from the sun December 6th 9:00am. Dense snow clouds, the near Untersberg is not visible, it snows. What can a photovoltaic deliver at this weather conditions. Solar power despite snowfall While the crystalline modul delivers even not enough voltage delivers the Three layer amorphous from Unisolar still 32,6 mA charge current. 398 mW from 0,5m². 12 noon in december The snowfall has changed to rain. For the human eye as dark as 3 hours berore, but Canon S1 and the Voltmeter show an evident increase. Cloudy but brighter December 7th 2005 in Gartenau. Between the clouds is a part of the Untersberg visible. Maybe a little brighter than yesterday. Measurement shows even brighter than yesterday at noon. Dusky or dusky? Difference 1.8 Subjectively, it's as dusky as yesterday. But the electric power yield shows between dusky yesterday 9:00 and today 12:00 is an 1:8 difference. Morning sun behind stratus Blue sky, over the near hill is some stratus. Subjectively is the weather much brighter than yesterday at 9:00am. But objectively, it was yesterday at the same time brighter. Winter sun behind light clouds Only 19 degree above the horizont is the sun behind light clouds. At horizontal photovoltaic, this brings only double compared to yesterday noon under clouds. Drawer below the staircase Finally the third furniture below the staircase. Because of the limited height is only a drawer possible.
