[0002] RVs have the dual purpose of being both a house and a car. They can be moved at any time and can be parked in a natural environment far away from the city. Therefore, they are sought after by many people who like to travel. Because RVs need to meet people's daily needs, a large number of living facilities and household appliances must be installed in the car. Generally, a generator is installed in the car, and a solar panel is installed on the roof to rely on solar power to meet the power needs of the car's electrical appliances.

[0003] RVs are often parked in shaded areas such as under trees, which causes part of the solar panel to be blocked. The solar panels currently used are generally composed of multiple strings of solar panels connected in series, and the final output line is connected to a junction box to conduct the current. It is impossible to protect multiple strings of solar panels separately. When one area is blocked and cannot generate electricity, the current generated by the normal operation of the remaining solar panels will pass through the circuit and flow through the blocked solar panel. At this time, the blocked solar panel is essentially a resistor in the circuit. When current passes through, it will generate heat and cause high temperature, which will cause the power generation efficiency of the entire solar panel to drop sharply. At the same time, high temperature can easily cause local solar panels to burn out or produce hot spots.

[0004] Therefore, it is necessary to provide a solar panel with heat spot protection for RVs to solve the above technical problems. Summary of the invention

When one area is blocked and cannot generate electricity, it will generate heat and cause high temperature when current passes through, which easily causes hot spots on local solar panels to burn out.

[0007] Preferably, the support frame is formed by splicing aluminum alloy profiles.

[0008] Preferably, the solar panel further comprises an outer frame, and a plurality of groups of solar panel modules are arranged and fixed in the outer frame.

[0009] Preferably, the outer frame is made of aluminum alloy, and corners are provided with wrap angles.

[0010] Preferably, the solar panel module is formed by connecting a plurality of solar panels in series.

[0011] Compared with the related art, the solar panel for preventing heat spots specially provided by the utility model for RV has the following beneficial effects:

[0017] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0018] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A front view of a solar panel for preventing heat spots specially provided for RVs according to the utility model; Figure 2 It is a top view of the utility model; Figure 3 for Figure 1 The back structure diagram of the solar panel shown. The solar panel for RV special heat spot protection includes a support frame 1, a solar panel 2 is arranged on the front of the support frame 1, and the solar panel 2 includes a plurality of groups of solar panel modules 22, and a junction box 3 is fixedly connected to the back of each group of solar panel modules 22, and the output end of the solar panel module 22 is electrically connected to the input end of the junction box 3, and the plurality of junction boxes 3 are connected in series in sequence.

[0019] The junction box 3 is a connector dedicated to the solar cell assembly, and an anti-backflow diode is installed in its circuit. The diode is an electronic component used for unidirectional current conduction. When the solar panel module 22 generates electricity normally, the current can flow out normally from the junction box 3 to charge the battery. When the solar panel module 22 cannot generate electricity normally, the diode can prevent the current of the battery or the other solar panel modules 22 from flowing back into the solar panel module 22, thereby protecting the solar panel module 22.

[0020] A diode is arranged in the front multiple junction boxes 3 to prevent hot spots and protect each solar cell module 22. Two diodes connected in series are arranged in the last junction box 3, one of which also protects the solar panel module 22 from hot spots, and the other diode acts on the entire solar panel circuit to prevent backflow.

[0021] A junction box 3 is installed on each solar panel module 22, and a bypass diode is arranged inside the junction box. The current generated by each group of solar panel modules 22 is collected and flows out after passing through the circuit in the junction box 3. When one of the solar panel modules 22 is blocked and cannot generate electricity, the diode plays a bypass protection role, diverting the current and temporarily not passing through the blocked solar panel module. The current generated by other unblocked solar panel modules 22 flows through the circuit of the junction box 3 of the solar panel module 22 and outputs the current normally. On the one hand, the loss of electric energy of the entire panel is avoided, and on the other hand, the blocked solar panel module 22 is prevented from heating up and causing overheating and burning. In this way, even if part of an area of ​​a solar panel module 22 is blocked and cannot generate electricity, other solar panel modules 22 can also work normally, and the current generated can also flow out normally for storage or use, so that the power generation efficiency of the entire solar panel will not be reduced too much, and each solar panel module 22 is also protected at the same time.

[0022] The support frame 1 is made of aluminum alloy profiles, which is light in weight, high in strength and not easy to be damaged.

[0023] The solar panel 2 further comprises an outer frame 21, and a plurality of groups of solar panel modules 22 are arranged and fixed in the outer frame 21. The outer frame 21 mounts and fixes a plurality of solar panel modules 22, and then is integrally mounted on the supporting frame 1.

[0024] The outer frame 21 is made of aluminum alloy, and corners are provided with corner covers 23 to prevent bumps and scratches.

[0025] Compared with the related art, the solar panel for preventing heat spots specially provided by the utility model for RV has the following beneficial effects:

[0026] The entire solar panel 2 is divided into a plurality of solar panel modules 22, and a junction box 3 is installed on each solar panel module 22. Each junction box has a bypass diode or an anti-backflow diode or both diodes. When one of the solar panel modules is blocked and cannot generate electricity, the current cannot flow through the blocked solar panel module, and the diode plays a bypass protection role, diverting the current and temporarily not passing through the blocked solar panel module. On the one hand, it avoids the loss of electric energy, so that the power generation efficiency of the entire solar panel does not decrease too much. On the other hand, it also prevents the blocked solar panel module from heating up, causing overheating and producing a hot spot effect and burning. This design protects each string of modules of the solar panel individually, thereby protecting the entire solar panel.
