Can solar panels still be used if they have hot spots?

Introduction Can the solar panel still be used if there are hot spots? It cannot be used. In addition to having a serious impact on the lifespan of solar panel components, the hot spot effect can also burn solar panel components or even cause fires.

Can solar panels still be used if they have hot spots?

Cannot be used.

In addition to having a serious impact on the lifespan of solar panel components, the hot spot effect can also burn solar panel components or even cause fires.

Under certain conditions, a shaded solar panel component in a series branch will be used as a load to consume energy generated by other illuminated solar panel components. The shaded components of the solar panel will generate heat at this time, which is the hot spot effect. This effect can seriously damage solar panels.

Generally speaking, it is estimated that when the temperature of the photovoltaic components of the solar panel is 30°C in normal operation and the local temperature is 6.5°C higher than the ambient temperature, the local solar panel This component can be considered a hot spot area.

Conditionsof the solar panel market

The European Trade Commission could propose in May to impose punitive customs duties of more than 30% on Chinese solar panels in order to protect European manufacturers.

Reuters cited diplomats as saying that EU Trade Commissioner Karel De Gut would propose imposing punitive tariffs on Chinese solar panels at the EU trade representatives' meeting on 8, and that she should receive support. In accordance with current European regulations, the relevant temporary tax measures will come into force before June 6.

However, even if the EU issues a preliminary decision by then, there will still be room for negotiation with China to resolve the issue. If both parties successfully negotiate, they can avoid punitive tariff measures that can be implemented for up to five years.

The European Commission has launched anti-dumping and countervailing investigations respectively into solar panels imported from China, involving Chinese companies' exports to the EU worth up to 21 billion euros (around 27 .6 billion US dollars), which is called by industry insiders The largest "double counterfeiting" case involving the largest sum of money in the history of the European Union.

The accessories of solar panel brackets mainly include the following types:

1. Support Frame: The support frame is the main part of the solar panel support. , generally made of steel. Or aluminum to support the installation of solar panels.

2. Bracket Bolts and Nuts: Bolts and nuts used to secure the bracket frame to ensure the stability and security of the bracket.

3. Support angle clamps and connectors: corniers and connectors used to connect the bracket frame, so that the bracket frame can be firmly fixed on the ground or building.

4. Stand Legs: The legs used to support the stand frame are usually made of steel and can be adjusted and fixed as required.

5. Bracket Rubber Pad: Used for buffer and protection between solar panels and support frames to prevent friction and damage.

6. Bracket Protective Cover: A protective cover used to protect the solar panel bracket. It can prevent dust, rain and other debris from entering the bracket, keeping the bracket clean and safe.

7. Bracket junction box: used for electrical connection of solar panels, connecting wires from solar panels to equipmentsuch as inverters or batteries.

8. Photovoltaic fixture: Photovoltaic bracket is mainly used in photovoltaic project scenarios on color steel tile roofs.

The above accessories are common for solar panel brackets. Specific types of accessories and methods of use may vary depending on different brands of brackets and installation requirements. When installing solar panel brackets, it is recommended to consult a professional photovoltaic installation company or engineer to ensure that the correct accessories are selected and used.
