Description

Technical Field

[0001] This invention relates to solar energy conversion and storage systems, and more specifically, to a grid-type solar tree energy system. Background Technology

[0002] "The energy the sun provides to Earth every hour is equivalent to the total energy consumed by human civilization every year. For solar energy enthusiasts, this figure speaks volumes. No other energy supply is as abundant as the 120,000 terawatts of energy that the sun continuously and freely provides. As long as a tiny fraction of this sunlight can be captured by photovoltaic cells and directly converted into electricity, all power plants will not emit any greenhouse gases" (Oliver Morton, Nature, 443, 19-22 (2006)). However, the energy flux density of solar radiation is extremely low, only 1,000 watts per square meter under standard conditions. If humanity hopes to completely replace fossil fuels with solar energy and fundamentally solve the problems of climate change and energy depletion, it will need to occupy vast amounts of land to collect solar radiation. The conflict between land for power generation and land for other uses will become a major challenge for humanity. The agricultural-solar complementary model provides an excellent example for resolving the land use conflict between photovoltaic power generation and agricultural production. This model can be flexibly extended to the forestry sector to form a new "forest-solar complementary" model—that is, combining forestry with photovoltaic power generation and coordinating the deployment of photovoltaic systems within forest areas. However, traditional photovoltaic modules and their installation methods can negatively impact crop growth and cannot be directly applied to forests, making it difficult to convert forests into solar power plants. Forests play a crucial role in environmental protection and ecological balance, and transforming deserts into forests is a significant human aspiration. Clearly, technological innovation in photovoltaic modules and installation equipment is the core key to achieving the coordinated deployment of photovoltaic systems with forests and converting forests into solar power plants.

[0003] This invention discloses a grid-type solar tree energy system that uses a grid-type photovoltaic system to cover individual trees or groups of trees in a forest, achieving solar power generation and energy storage without affecting tree growth. The system includes: a discrete small photovoltaic module array with bypass diodes, a grid for covering the trees, a battery bank with replaceable battery modules, and a charging controller. The discrete small photovoltaic modules are dispersed and fixed on the grid and connected by cables; the grid covers the trees; the entire photovoltaic module array is connected to the battery bank to charge the battery modules.

[0004] The system has significant advantages: First, the gaps between the separate small photovoltaic module arrays allow sunlight to penetrate and reach the trees, ensuring their growth; second, the grid provides a flexible installation platform for the photovoltaic modules; third, the battery packs with replaceable battery modules enable energy storage, and the stored energy can be transported to other locations by replacing the battery modules; fourth, the entire system requires no support structure or brackets, significantly reducing the overall system cost.

The discrete small photovoltaic modules with bypass diodes are connected by cables to form a discrete small photovoltaic module array with bypass diodes. The grid is used to cover trees. The entire photovoltaic module array is electrically connected to the battery pack to charge the battery modules.

[0007] The system has significant advantages: First, the gaps between the separate small photovoltaic modules allow sunlight to penetrate and reach the trees, ensuring their growth; second, the grid provides a flexible mounting platform for the photovoltaic modules; third, the battery pack with replaceable battery modules enables energy storage, and the stored energy can be transported to other locations by replacing the battery modules; fourth, the entire system requires no support structure or brackets, significantly reducing the overall system cost.

[0011] Figure 2 This is a schematic diagram of a discrete small photovoltaic module array structure with bypass diodes.

[0012] Figure 3 This is a schematic diagram of a battery pack with a replaceable battery module and a charging controller. Detailed Implementation

[0013] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Where possible, the same reference numerals in the drawings will be used to refer to the same or similar parts.

[0014] Reference Figure 1 The grid-type solar tree energy system includes: 1) a discrete small photovoltaic module array 100 with bypass diodes; 2) a grid 200 for covering individual trees or groups of trees in a forest; and 3) a battery pack 300 with replaceable battery modules and a charging controller. The discrete small photovoltaic module array 100 with bypass diodes is fixed to the grid 200; the grid 200 is used to cover trees in the forest; the photovoltaic module array is electrically connected to the battery pack 300 to charge the batteries.

[0015] Reference Figure 2 The discrete miniature photovoltaic module array 100 with bypass diode includes: 1) a discrete miniature photovoltaic module 110; and 2) a bypass diode 120. When the photovoltaic module array is facing away from the sun due to solar motion, the bypass diode will conduct to bypass the current.

[0016] Reference Figure 3 The battery pack includes: 1) a battery pack frame 310; 2) a replaceable battery module 320; and 3) a charging controller 330. The replaceable battery module 320 can be charged via a detachable small photovoltaic module 110 and can be replaced to transport the stored energy to other locations.

[0017] The working principle of the grid-type solar tree energy system is as follows: When sunlight shines on trees covered with a grid of photovoltaic modules, a portion is collected and converted into electrical energy, while the other portion penetrates into the trees through the gaps between the individual small photovoltaic modules 110, ensuring tree growth. When a small photovoltaic module 110 on a tree is positioned away from the sun due to solar movement, a bypass diode bypasses the current flowing through that module. The electrical energy generated by the photovoltaic modules is conducted to the battery pack to charge the replaceable battery module 320. After charging, the replaceable battery module 320 can be transported to other locations for use in scenarios such as charging swappable electric vehicles.

[0018] Each discrete miniature photovoltaic module in the array of discrete miniature photovoltaic modules with bypass diodes is connected in parallel with a bypass diode.

[0019] In the battery pack with replaceable battery modules and the charging controller, the charging controller is electrically connected to each replaceable battery module.

[0020] As described above, the grid-type solar tree energy system has several advantages: the grid provides support for the photovoltaic module array, the separate small photovoltaic modules ensure that the trees receive sufficient solar radiation; the bypass diodes ensure that the photovoltaic module array operates normally throughout the day as the sun rises and sets; and the replaceable battery modules solve the problem of energy storage and consumption in off-grid environments.
