In recent times, the German government frequently rumours in the field of solar energy to reduce the so-called "dependence on China" sound. Local time on December 17, the German economy minister Habeck (Green Party) accepted the German media "German editorial network" (RND) interview, said he plans to provide state subsidies to strengthen the power of the country's solar energy manufacturers, and compete with Chinese manufacturers.     "German solar products comply with certain criteria that products from other countries do not, for example, German manufacturers often operate efficiently without the use of hazardous chemicals ......," Habeck said, therefore, German manufacturers "should be rewarded for this resilient contribution."     Habeck said he plans to subsidise local solar manufacturers at the national level through Germany's Renewable Energy Act, and that "the current parliamentary proposal for a 'solar package' makes the implementation of state subsidies possible". The RND reports that the "solar package" was originally scheduled to come into force at the beginning of this year, but discussions in the German Bundestag have been postponed until around January next year.     In any case, we have the firm goal of realising the planned projects," says Habeck. We have strong and innovative companies, and other companies that want to invest here are also interested. We should make the most of it." He also called on German manufacturers to actively market their products, for example, by "launching a drive to provide special offers for German products."     Habeck emphasised the importance of the solar sector for job creation, and that "it is important for Germany that domestic products have at least a basic share of the domestic market". It is also a question of economic security, he said, "We cannot rely entirely on imports."       Initially, the German Federal Ministry of Economics planned to use 1.3 billion euros (about 10 billion yuan) to provide subsidies for German manufacturers, and asked the states to provide financing schemes for the local photovoltaic industry. But the German Constitutional Court ruled last month to cut most of the budget of the German government's proposed "Climate and Transition Fund". Now, the Ministry of Economy wants Parliament to adopt a "solar package" to continue to support domestic manufacturers.     Not only Germany, the European Union has recently been planning a similar subsidy programme. Reuters reported in October that in recent years, China's solar panels to European manufacturers brought "enormous price pressure". Germany, led by the European Union countries are trying to reduce dependence on China in the field of solar energy, plans to use subsidies or "tariff peaks" and other tools to protect the European Union photovoltaic enterprises.     Data from the European Commission show that more than 90 per cent of the silicon ingots and wafers used to manufacture solar panels in the European Union come from China. Currently, there is an oversupply and low prices of solar panels in Europe. The European Solar Manufacturing Commission (ESMC) said that prices have fallen from a peak of about 0.24 euros per watt at the beginning of the year to about 0.15 euros, while European manufacturers priced at 0.30 euros.     However, some industry insiders revealed that there are differences within the German enterprises, and some installers questioned the move as trade protection. At the same time, some European solar companies also grouped to express opposition. Swiss photovoltaic executives said that tariffs are not the optimal solution to the current challenges, while the European Photovoltaic Industry Association warned that a potential tariff war would lead to a "lose-lose" situation and seriously undermine Europe's ability to deploy clean energy.

Required Certification! ETN Certification for PV Racking Systems for Rooftop Projects in France After Intersolar 2023 in Munich, Germany, the French ETN certification for PV module racking systems has been on the radar of more and more Chinese racking manufacturers. As of September 2023, although no Chinese racking manufacturer has yet obtained the French ETN certification, more and more Chinese racking manufacturers in the market have started to enquire about or plan for the certification application, planning to enter the French rooftop market. At the same time, most Chinese module manufacturers are also arranging to enter the ETN white list of French racking manufacturers in order to gain entry into the French rooftop and car park PV roofing market.   What is the French ETN certification for racking systems?   ETN (Etude de Technique Nouvelle) - Etude de Technique Nouvelle - is a technical study carried out by the French Control Office and the Centre de Science et Technique de la Construction (CSTC) on the compatibility of the racking system and PV modules, checking the overall system's waterproofing, mechanical resistance, protection against wind, resistance to compression, fire risk, and other key points and feasibility in different geographical areas.   The ETN certification for mounting systems in France is awarded to the manufacturer of the mounting system by a qualified certification body after testing and evaluating the mounting system and its matching components. ETN certified mounting manufacturers can work with different PV module manufacturers to add their modules to the white list of mounting installers, proving the compatibility of the modules and the mounting system.   In terms of necessity, before implementing a French rooftop PV and carport PV installation project, the installer's insurance company usually requires an ETN certification from the racking system manufacturer, as well as verification that the module products used in the project have been entered into the whitelist of that racking manufacturer, in order to validate the safety of the installation system and grant the installer ten years of insurance coverage. Without ETN certification, neither the bracket manufacturer nor the module manufacturer can be on the installer's supplier list. ETN certification is therefore essential for both bracket and component manufacturers entering roofing and carport projects in France.

At the Q3 2023 earnings briefing held this afternoon, DEYE Vice Chairman and General Manager Zhang Dongye said, "The incident in Germany has been properly handled, and this incident only affects the sales of the company's micro-inverter products in Germany in the short term. At present, the company has launched a new generation of micro-inverter products, and the market is recovering gradually. At present, the company's European inverter inventory is small, but the industry inventory is still in the process of selling and it is expected that it will be able to adjust to the normal state within one to two quarters (next year)."  In July this year, DEYE was exposed to the existence of microinverters produced and sold that were inconsistent with certification. DEYE then announced that the company's microinverter products sold to Germany lacked relays due to the deviation in the understanding of the relevant personnel of the company of the differences between the VDE4105 and UL1741 standards, and in consideration of the service life of the products.

Micro inverter: DC-AC, converts direct current (DC) to alternating current (AC) and functions in the same way as a string inverter, except that because of its small size, it can be mounted directly underneath solar PV panels. Micro inverters can use solar energy to convert to AC power for people's daily use.     Micro-inverters are classified as single-phase and three-phase. Single-phase micro-inverters are suitable for residential neighbourhoods and small businesses. Three-phase micro-inverters are a bit higher than single-phase in terms of performance and stability and efficiency, and are suitable for commerce and industry.     Each solar panel is directly connected to a micro-inverter in parallel connection. The form of micro-inverters can be set up as one to one (each micro-inverter is connected to one PV module), one to two, one to three, one to four, etc., depending on the microgrid model.    String inverters are installed in series with the solar panels, so the amount of power generated by each panel is limited, and the amount of power generated at the top of the house will be lower. Micro-inverters have the advantage of being simpler to install, monitoring and optimising each solar panel individually to achieve the highest efficiency in solar energy usage.
