Technical field
The present invention relates to a kind of spinning solution, especially a kind of spinning solution of Three Degree Of Freedom compact optical photovoltaic array belongs to
In the technical field of photovoltaic array rotation.
Background technique
Solar photovoltaic technology is the renewable energy technologies for converting the luminous energy of sunlight to electric energy.Currently, with
It is photovoltaic cell in the minimum unit of photovoltaic power generation, several photovoltaic cell series/parallels constitute photovoltaic module, several photovoltaic modulies
Series/parallel constitutes photovoltaic array.For traditional photovoltaic array, addressing generally on open level land or roof, is set early period
Meter can be according to the appropriate distance of local sunshine situation setting front and back photovoltaic panel.The purpose for the arrangement is that preventing photovoltaic array by portion
Divide and block, cause loss in efficiency, or even generates hot spot and cause DC Line Fault electric arc fire.
With the increasingly popularization that photovoltaic technology is applied, distributed photovoltaic is by its adaptation to local conditions, clean and effective, nearby consumption
The advantages that, the favor by market more and more.As one kind of distributed photovoltaic, photovoltaic is built by photovoltaic power generation and building
Function organically combines, and has both the functions such as power generation, sunshade, beauty.But in practical applications, compared with conventional photovoltaic array, building
Photovoltaic is faced with the problems such as small space, shadow occlusion, needs using the installation method for being different from conventional photovoltaic.Especially it is used for window
The photovoltaic array of body will take into account generated energy, daylighting and prevent dazzle.
The prior art includes the photovoltaic array of uniaxial photovoltaic shutter window and twin shaft；But both modes can not have
Effect avoids forms from blocking photovoltaic blade or array.
Summary of the invention
The purpose of the present invention is overcoming the deficiencies in the prior art, a kind of Three Degree Of Freedom compact optical photovoltaic array is provided
Spinning solution, can guarantee without mutual shadow occlusion between photovoltaic array, and can avoid forms and the shade of photovoltaic array is hidden
Gear, generated energy keeps maximum, while guaranteeing indoor daylighting, and can prevent strong daylight from generating dazzle.
According to technical solution provided by the invention, a kind of spinning solution of Three Degree Of Freedom compact optical photovoltaic array, the rotation
Shifting method includes the following steps:
Step 1 provides photovoltaic array and the photovoltaic array is installed on desired position, all light in photovoltaic array
It lies prostrate unit and uses identical rotation mode；
Step 2 determines position of sun according to position, current date and the current time that photovoltaic array is installed, it is described too
Positive position includes altitude of the sun αs, azimuth As, and convert identified position of sun to the vector n in cartesian coordinates
(xs,ys,zs):
Step 3, when position of sun variation after, by photovoltaic array follow variation after position of sun rotate, with eliminate
The shadow occlusion of photovoltaic array；Wherein, when photovoltaic array being rotated,
In cartesian coordinate system, the positive direction of x-axis is due south, θyIt is suitable around y-axis from initial position for photovoltaic array unit
The angle of hour hands (in terms of the positive direction of y-axis) rotation, θzIt is photovoltaic array in rotation θyAfterwards around z-axis counterclockwise (from the pros of z-axis
To seeing) angle of rotation；θnIt is photovoltaic array in rotation θzAfterwards around unit vector nPVClockwise (from unit vector nPVPositive direction
See), unit vector nPVTo pass through origin and the unit vector vertical with photovoltaic surface.
The initial position of the photovoltaic array is that all photovoltaic cells keep vertical in photovoltaic array.
Advantages of the present invention: after position of sun variation, photovoltaic array is rotated, can guarantee nothing between photovoltaic array
Mutual shadow occlusion, and can avoid forms to the shadow occlusion of photovoltaic array, generated energy keeps maximum, while guaranteeing indoor adopt
Light, and can prevent strong daylight from generating dazzle.
