Embodiment
The photoelectric conversion rate of solar panel has crucial effects in photovoltaic generating system; Therefore; Be engaged in those skilled in the art's ground innovation and creation of always enjoying it and go out to improve the method for photoelectric conversion rate; Comprise the material that changes the solar cell intralamellar part, improve processing technology of solar panel or the like.Simultaneously, through tracking, also be the effective light-receiving area that improves solar components, and then effectively improve the important means of day energy output sunlight.
In view of prior art generally adopts fixed installation solar panel (hereinafter to be referred as PV) or adopts diaxon rotation adjustment PV to realize that there is many-sided serious deficiency in the mode of solar tracking, is difficult to be applicable to the photoelectric conversion efficiency of solar panel in the compact applications system.
Summarize the technical scheme that the present invention realizes low-cost solar tracking, it mainly realizes solar tracking through accurate control single shaft rotation.As shown in Figure 2; Latitude according to Application of Solar Energy region of living in; On the installed surface of level, be angle fixed installation solar panel 1 with latitude θ; The synchronous position of sun conversion of one in the actuating force lower edge axis of solar panel (relying on supporter) rotation perpendicular to horizontal plane, and the current location that the rotation angle satisfies the sun is among the center line face of solar panel constantly.The diagram supporter is elongated axostylus axostyle 21, and it also can be other arbitrary structures form certainly.
Wherein, the center line face of solar panel is and the symmetrical centre face of solar panel vertical interlaced that more properly describe: rotation also is positioned among this center line face.This solar panel carries out controlled rotation and resets along axis in 0~180 ° angular range.
More specifically see: different according to the each department latitude, be fixed angle with horizontal mounting surface when making PV be installed on supporter, this angle is the local latitude angle, and PV can be vertical with the sunlight angle during Winter Solstice in assurance; Supporter can be by an axis rotation perpendicular to horizontal plane simultaneously.The control anglec of rotation guarantees that the position of the sun is in the center line face of PV constantly, thereby improves effective light-receiving area of PV.
Because every day, the irradiation of sunlight direction was that revolution and rotation rule by the earth determines, so can calculate the residing position of the sun according to this rule and local latitude and time.Control section in this PV sun tracking system preferentially is the rotation that axle is controlled whole system with time; In control, will cook up a plurality of chronomeres daytime; And according to the sun present position that calculates in each chronomere, control PV azimuth guarantees that the sun is in the center line face of PV.
Again from hardware structure; The system of solar panel single shaft solar tracking method of the present invention; Comprise a supporter that is vertical on the horizontal mounting surface; Be located at the solar panel that is fixedly attached on supporter; A drive unit and a control device that is used to control supporter rotation angle that drives the solar panel rotation, wherein angle is the latitude θ of Application of Solar Energy region of living between PV and horizontal mounting surface, and the control device output current location that satisfies the sun is in the drive unit that controls signal among the center line face of solar panel constantly.
Specify this single shaft sun tracking system from concrete application, as shown in Figure 3, be the running sketch map of one embodiment of the present invention.Visible from illustrating: this supporter is elongated axostylus axostyle 21 present embodiment, and the axostylus axostyle bottom is driven with drive unit and joined.Solar panel 1 rises one day change in location that the west falls according to sun east, under the rotation of axostylus axostyle 21 drives all the time towards solar irradiation.According to aforementioned diurnal variation rule to position of sun, can appropriate design supporter rotation angle, thus control is satisfied the current location of the sun and is in constantly among the center line face of solar panel.Here, axostylus axostyle 21 can adopt and drive rolling bearing realization rotation; Solar panel then can be various standard geometrical shapes, for example circular, square or rectangle.
More than be the principle control mode of present embodiment sun tracking system, in addition, according to many difference of application requirements, its control mode also has following multiple mode.
Promptly can calculate the time of the setting sun corresponding to the earth position relation different with the sun according to the different latitude Various Seasonal; The system that arrives after this time will control PV and turn in the east; The solar tracking control system quits work and waits for that m seq begins second day work, can guarantee efficient and reliability that system is higher like this.
Can judge weather conditions according to the PV output voltage, can be judged to be overcast and rainyly when the PV output voltage is low that this magnitude of voltage can obtain according to different PV characteristics, geographical position and overcast and rainy intensity of illumination test when daytime.When this PV output voltage values is lower than this voltage and is higher than minimum operating voltage owing to be overcast and rainy, PV towards little with the correlation of generating capacity, do not need the solar tracking action, wait for voltage raise be non-when overcast and rainy control PV towards forwarding accurate position fast to.When the PV output voltage was lower than minimum operating voltage, can not there be output in system, did not therefore need the solar tracking action.
As shown in Figure 4, be the running sketch map of another preferred embodiment of the present invention.Visible from illustrating; This supporter is a geometry column shape; Comprise as the main body 22 of fixed structure and the rotation track 221 of the flat-shaped set annular of main body top water; And rotation track 221 is driven with drive unit (not shown) to join, and the geometric center of this solar panel 1 is concentric relative with rotation track, and the inclination lower edge of solar panel 1 and rotation track 221 Joints.In the present embodiment; Adopt motor to make drive source, drive rolling bearing and drive rotation track 221 rotations (mechanical known technology is so will not illustrate and give unnecessary details); Drive the solar panel and the sun thus and keep the most reasonably irradiated area, thus the day energy output of raising solar energy.
This shows; Use technical scheme of the present invention, compare to the sun tracking system of hard-wired solar panel and traditional diaxon rotation adjustment, can the light-receiving area of the solar panel during in the morning with the dusk in a day have been brought up to more than 50% from 0 effectively; Improved a day generating efficiency; And effectively saved structure and cost and the energy consumption controlled, satisfied the photoelectric conversion efficiency of solar panel in the compact applications system, also the application to solar energy has impetus.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within protection scope of the present invention.
