Formula of photovoltaic bracket

The formula of photovoltaic bracket is as follows

1, maximum bearing capacity formula: fmax = σ× a, where fmax represents the maximum bearing capacity, σ represents the yield strength of the scaffold material, and a represents the cross-sectional area of the scaffold.

2. Weight formula of bracket: w = ρ× v, where w represents the weight of bracket, ρ represents the density of bracket material, and v represents the volume of bracket.

3. Calculation formula of inclination angle: β = φ+λ-θ. Where β represents the inclination angle of the solar panel, φ represents the latitude where the solar panel is located, λ represents that the solar panel faces due east 0 degrees, due south 90 degrees, due west 180 degrees and due north 270 degrees, and θ represents the altitude angle of the sun.

Photovoltaic power generation is a way to convert light energy into electric energy by using solar energy, and photovoltaic brackets and components are indispensable parts of photovoltaic power generation system. In photovoltaic power generation system, the design and calculation of photovoltaic bracket is very important, which is directly related to the installation stability and efficiency of photovoltaic modules.

Many factors need to be considered when calculating photovoltaic brackets and components, including the angle of sunlight, the material and stability of brackets. Among them, the most commonly used formula is the formula for calculating the peak power Pmax of solar photovoltaic panels: Pmax = Isc *(Voc-Vm)/(Voc-Vm ref). Where Isc is short-circuit current, Voc is open-circuit voltage, Vm is battery output voltage, and Vmref is the reference value of battery output voltage.

The calculation results of this formula can be used to evaluate the output power of photovoltaic modules, so as to further determine the design and installation mode of brackets. In addition, when calculating the stability of photovoltaic bracket, the structure and material of bracket should also be considered. Usually, photovoltaic brackets are made of weather-resistant steel, which has good corrosion resistance and strength.

In addition to the calculation formula, it is also necessary to pay attention to the installation angle of photovoltaic modules. The installation angle of photovoltaic module has great influence on the incident angle of light and energy utilization efficiency. Therefore, when calculating the photovoltaic bracket, the best installation angle of photovoltaic modules should be considered to improve the power generation efficiency of photovoltaic system.

To sum up, the design and calculation of solar photovoltaic power generation system need to consider the stability and efficiency of photovoltaic brackets and components. Using the peak power calculation formula of photovoltaic module, the output power of photovoltaic module can be evaluated, and then the design and installation mode of bracket can be determined. In addition, it is necessary to pay attention to the optimal installation angle of photovoltaic modules to improve the energy utilization efficiency of photovoltaic systems.
