Embodiment example 1

[0022] as attached figure 1 In the six solar panels 1 shown, there are 72 photovoltaic cell units 2 in each panel. At present, the maximum capacity of solar photovoltaic cells is 7.7A, the theoretical power of a solar panel is 7.7A×112.5V, or 866 watts, and the total power of 6 sail panels is 5196 watts. If the three-parallel two-series method is adopted, the potential system internal resistance value of each component at this time is the ratio of the sum of the total normal voltage V to the total normal current I: open circuit voltage / set current=225V / 23.1A=6.4 Ω

[0023] The resistance of the photovoltaic module system cannot exceed the allowable value of 1.82Ω. When it exceeds 1.82, the current conversion will attenuate itself by 5.5% every time the resistance is doubled.

[0024] The current attenuation value caused by the internal resistance of the component = (6.4Ω÷1.82×5.5%×7.7)A=1.49A

[0025] Then, when the operating voltage of each sailboard is 112V, the actual ou...

Embodiment example 2

[0029] as attached figure 2 As shown, there are 6 solar photovoltaic battery panels 1, and there are 18 photovoltaic battery units 2 in each sailboard. The working voltage of each block is 13V, the working current is 14A, and the output power is 182 watts. In this specific embodiment, the 6 solar photovoltaic panels are first divided into two groups, three groups are connected in parallel, and then the two groups are connected in series to obtain a voltage of 26V and a current of 42A. At this time, the overall normal voltage of the assembly is V When the ratio of the sum to the total normal current I is the system resistance K=1.62, that is, under the condition of 0.55≤K≤1.82, the rated current of 42A can be fully output, and the total active power of the components can be fully output.

[0030] However, if 6 solar photovoltaic panels are concentrated and paralleled at the same time, although the nominal current is 84A, and the power generated together, the total device (182...

Abstract

The invention relates to a solar photovoltaic battery, in particular to a high-efficiency solar photovoltaic battery pack which is formed by combining a plurality of solar photovoltaic battery units for purpose of improving output power and current. The high-efficiency solar photovoltaic battery pack is characterized in that the ratio between the sum of total normal voltage V of the photovoltaic battery and total normal current I is k which is equal to or lower than 1.82 and equal to or higher than 0.55. By regulating the potential of the photovoltaic battery pack and the internal resistance value of a component system in terms of fixed ratio, the solar photovoltaic battery pack improves the effective output of rated currency and also the electric substance output of solar photovoltaic battery components with the same photic areas and the same theoretical powers to an unprecedented extreme, therefore, under the present international solar energy general technical conditions, the average conversion rate is improved from the original low efficiency of 15 percent to an efficiency as high as 100 percent, wherein the generation capability of common silicon-based batteries is improved upto 6.666 times than that of the original capability.

Description

technical field [0001] The invention relates to a solar photovoltaic battery, in particular to a high-efficiency solar photovoltaic battery group composed of a plurality of solar photovoltaic battery units for increasing output power and current. Background technique [0002] Studies have shown that: in space, every cubic meter of dark and humid air; every square meter of illuminated area contains a static electricity equivalent to 274-320 amperes of current, but these electrostatic substances with a vast source of wealth have their own original voltage. The electromotive force is only 0.55 volts, which is only suitable for photosynthesis with the human body, animals, and plants. In the absence of zero-resistance superconductors, molecular charges often exist, such as petroleum, ore, plants, and animals, all of which have accumulated a large amount of molecular energy. Molecular energy is positively and negatively balanced. Molecular charges usually maintain a Relatively pr...
