Energia Solara

FLAT SOLAR COLLECTOR

1.1 - Constructive form - FLAT;

1.2 - Requires tracking system of the sun
(overheating);

1.3 - Nothaving a tracking system, the power
performance is reduced with 28,87% (in a day light);

1.4 - Being flat, it doesn't have the possibility of
catching additional diffuse light;

1.5 -In nebulous time (dark, rainy, foggy, etc.), the flat
shape of the sensor will only capture 18% of the
solar energy, that is 18% from the capacity of this
type of captator specific to a sunny period;

1.6 - Known solutions don't have the possibility of
heating the water in winter time, this is only made
possible through appropriate adaptations;

1.7 - The constructive form and the conception of the
flat solar collector system, doesn't permit it's use for
example:
- For creating mechanical work in agriculture. (As
known, the orientation of plots that must be
processed can be in anyway, therefore, only a
spherical collector can be suitable(appropriate);

1.8 - Due to reduced energy performance is not
known whether the flat collector allows adaptation to
a universal system of solar energy capture
throughout the 24 hours and that provides heat
transfer from south to north and back in order to
annihilate temperature differences due to the
seasons.

SPHERICAL SOLAR COLLECTOR

2.1 - Constructive form, spherical;

2.2 - Being spherical it doesn't require a system to
follow the sun (overheating is excluded);

2.3 - Being spherical, on a sunny time, the energy
performance is permanently 136%.
- 100%+(2x18%)=136% (sunny time);
- 18%x4=72% (nebulous time);

2.4 - Being spherical,the half located in the shadow of
the collector produces 2x0,18=0,36 namely 36%
additional energy produced by the half-lit by the sun;

2.5 - Being spherical, in nebulous time (dark), the
collector will capture 4x18%=72% solar energy,
knowing that the lateral surface of a sphere is four
times bigger then the area of a flat surface, and the
power absorbed in nebulous time is 18% of that
absorbed when the sun shines (see book
"Introduction to Solar Energy for Scientist and
Engineers", de Sol Wieder);

2.6 - By design, it is provided the possibility that
when the outside temperature is below 0 ° C, by
converting the captured electricity to heat water with
known heaters;

2.7 - Being spherical and having a great efficiency,
spherical solar collector can be used in agriculture -
for instance - solar electricity collected any time and
in any working position can be transferred to an
electric motor vehicle properly made which will
allow elimination of the current agricultural tractor
which has a very low yield and is producer of
pollution (see system description);

2.8 - In the presentation of the spherical solar
collector, are presented methods for collecting solar
energy for 24 hours and transfer heat from one
hemisphere of the earth to another, using solar
energy converted to high voltage electricity
