    January 30, 2024

    On January 18, data from the Ningxia Power Trading Centre showed that as of 0:00 that day, Ningxia's cumulative outgoing power reached 700.2 billion kWh, breaking the 700 billion kWh mark in one fell swoop, equivalent to the in situ conversion of 280 million tonnes of standard coal, reducing emissions by 700 million tonnes of carbon dioxide, 190 million tonnes of carbon dust, 10.5 million tonnes of nitrogen oxides, highlighting Ningxia's energy transition to low carbon, helping energy green low-carbon and efficient use of energy, highlighting the practical achievements of Ningxia's low-carbon energy transformation and fuelling the green and efficient use of energy. According to the calculation of 947 kWh of electricity per capita per year for China's residents in 2022 announced by the National Energy Administration, 700 billion kWh of electricity is enough to support the country's 1.4 billion population for 192 days. Ningxia, as an important sending end of China's "West-East Electricity Sending" strategy, has rich coal, solar and wind energy resources. 2023, Ningxia actively play the role of inter-provincial power market, scientific scheduling, fine operation and maintenance, increase inter-region and inter-provincial power support, cumulative total organisation of 335 outgoing transactions, the annual outgoing power 877 billion kilowatt-hours, ranked fifth in the State Grid provinces to provide outgoing support for the Hangzhou Asian Games, the Chengdu Universiade. The total number of outgoing transactions organised is 335, and the amount of electricity sent out for the whole year is 87.7 billion kWh, which is ranked fifth among all the provinces in the State Grid network, and it provides outgoing support for the Asian Games in Hangzhou and the Universiade in Chengdu, and helps the national electric power supply guarantee "one board chess".   It is understood that in Ningxia sent 700 billion kilowatt-hours of electricity, new energy power reached 79.5 billion kilowatt-hours, accounting for 11.4 per cent of the total amount of electricity sent to the "14th Five-Year Plan" end of the Ningxia-Hunan power transmission corridor is completed, this ratio will be significantly increased. Ningxia in all efforts to ensure that the carbon peak carbon and the goal of achieving the process, innovative implementation of the "wind and fire" bundled transmission, new energy power transmission scale growth year by year, achieved by the transmission of "fire" power to the transmission of "green" power transformation, to put the "fire" power to the "green" power. The transformation of electricity from "fire" transmission to "green" transmission has been achieved by sending clean energy from Ningxia to the whole country, contributing to the construction of a new type of energy system and the promotion of high-quality development of energy with the wisdom of Ningxia and the Ningxia programme. It is particularly worth mentioning that in 2023, the State Grid Ningxia Electric Power Co., Ltd. flexibly carry out energy for capacity, flexible trading, new fire bundling and other transactions to promote the new energy transmission and consumption of 13.7 billion kilowatt-hours, improve the new energy transmission ratio of 35 per cent, reduce the new energy abandonment rate of 2.5 percentage points, to ensure that the new energy power annual utilisation rate to remain at more than 97 per cent.   Ningxia in-depth implementation of the national energy strategy, relying on the national unified power market, has built and put into operation Ningxia to Shandong, Ningxia to Zhejiang, two power transmission "artery", and in the construction of the third Ningxia to Hunan power transmission channel, in order to ensure the reliable supply of electricity in Ningxia, at the same time, will be the power through the DC transmission channels continue to be sent out! Sent out, power trading also by the initial Shandong, Zhejiang extended to the current Shanghai, Chongqing, Hubei and other provinces, to protect the power needs of North China, East China has played a positive role, but also to achieve a high quality of the new energy in Ningxia in the local consumption and the optimal allocation of a wide range of power, and vigorously promote the transformation of the resource advantages of Ningxia to economic advantages, creating various types of economic benefits of more than 160 billion yuan for the local Ningxia, increasing employment of more than 60,000 jobs. More than 60,000 jobs have been created.   In order to do a good job in the lean operation and maintenance of the existing two DC transmission channels and improve the efficiency of power grid utilization, State Grid Ningxia Power Co., Ltd. has set up a science and technology innovation centre and a DC innovation studio to make scientific and technological innovation a source of motivation to promote the high-quality operation and inspection of the DC system, and has independently researched and developed a variety of intelligent robots, drone carriers, a full set of anti-falling foot pegs, rope devices, drone nests, and related intelligent platform software systems, and continues to promote the transformation of scientific and technological achievements projects into applications on the ground.

  • How photovoltaic panels charge the batteries?
    January 24, 2024

    With the increasing sophistication of renewable energy technologies, photovoltaic (PV) power systems have become the green energy solution of choice for many homes and businesses. In this system, photovoltaic panels play a key role in converting solar energy into electricity, while the battery is an important component in storing this electricity for emergencies. So how do PV panels charge the batteries? This paper explores in detail the working principle, practical applications and optimisation strategies of this process.   First, the basic principle of photovoltaic panels to charge the battery   Photovoltaic panels, also known as solar panels, are made up of multiple solar cells. When sunlight hits the photovoltaic panel, photons hit the silicon atoms in the cell sheet, causing them to release electrons. These free electrons form an electric current, known as a photovoltaic current, inside the cell sheet. The photovoltaic panel draws this current through the positive and negative electrodes, supplying it to external circuits. A battery, on the other hand, is a device capable of storing electrical energy, which is converted into chemical energy and stored through an internal chemical reaction. When electricity is needed, the battery converts the chemical energy into electrical energy and releases it through a reverse reaction.   In a photovoltaic power generation system, the photovoltaic panel is connected to the battery through a controller. The role of the controller is to regulate the output voltage and current of the photovoltaic panel to match the charging requirements of the battery. When the sun is sufficient, the current generated by the PV panel is regulated by the controller to charge the battery. When the battery is fully charged, the controller automatically cuts off the charging circuit to prevent overcharging from damaging the battery.   Second, Precautions in practical application Matching problem: When choosing PV panels and batteries, make sure that their parameters such as voltage, current and capacity are matched. If the output voltage of the PV panel is too high or too low, it may affect the charging effect and life of the battery. Installation environment: The installation location of PV panels should try to choose a sunny and unobstructed place to improve the photoelectric conversion efficiency. At the same time, also pay attention to the tilt angle and orientation of the PV panel, these factors will affect its power generation effect.   Controller selection: the controller in the photovoltaic power generation system plays a key role, to choose the quality of reliable, functional controller. Some advanced controllers also have anti-reverse charge, anti-overcharge, anti-over-discharge and other protection functions, can better protect the battery.   Optimisation Strategies and Recommendations Regular inspection and maintenance: in order to ensure the normal operation of the PV power generation system, the working status of components such as PV panels, batteries and controllers should be checked regularly. If any abnormality is found, they should be repaired or replaced in time. Intelligent charging management: With the development of IoT technology, some advanced charging management systems are able to realise remote monitoring and intelligent charging. These systems can automatically adjust the output of PV panels and the charging strategy of batteries according to real-time weather, electricity demand and other factors to improve energy utilisation efficiency.   Diversified energy supply: Where conditions permit, consideration can be given to combining photovoltaic power generation systems with other renewable energy technologies (e.g., wind, water, etc.) to form a diversified energy supply system. This will not only improve the stability of energy supply, but also reduce the risk of dependence on a single energy source. In conclusion, the process of charging batteries with PV panels involves the collaborative work of multiple links and components. To ensure the smooth running of this process, it requires in-depth exploration and continuous improvement at multiple levels, including principle, practice and optimisation. With the continuous progress and innovation of science and technology, it is believed that photovoltaic power generation systems will create a greener and more sustainable energy future for mankind in the future.

  • To reduce pressure on the grid, Philippine government urges citizens to install solar panels
    January 15, 2024

    To mitigate the possible impact of the El Niño phenomenon on summer-season power and to reduce the dependence of households on the grid for electricity, the Philippine Energy Regulatory Commission (ERC) is encouraging the public to use solar home systems. The ERC noted that the licensing process for the installation of solar panels on homes has been simplified. In addition, the authority has partnered with various local governments to set up a one-stop office to facilitate applicants in obtaining permits for the installation of solar home systems. The agency noted, "Applicants who want to obtain a licence no longer need to travel to the Energy Regulatory Commission's head office; they can go directly to the one-stop office of the local government and quickly go through the licence process." Meanwhile, the authority will also work with the state-owned LandBank to provide assistance in funding for households interested in installing residential solar power, as well as develop projects to assist cooperatives in solving any energy problems that may arise during the dry season.  Earlier, the Philippine Department of Science and Technology (DOST) said the country will feel the strong effects of El Niño in the first or second quarter of 2024. It noted that 65 provinces in the country will face drought by the end of May. President Marcos has previously stressed the importance of having a steady supply of water and electricity during El Niño.

  • How Does Xinjiang's Photovoltaic Panels Generate Electricity in Winter When It Snows?
    January 04, 2024

    Come to a photovoltaic base in Shihezi City, Xinjiang, the surrounding goose feather snow, the temperature fell to minus ten degrees Celsius, but some of the photovoltaic panels on the snow has melted part of it. This is thanks to the double-glass components so that the photovoltaic panels double-sided power generation. According to the base of the relevant person in charge of Wang Runsheng introduction, the sunlight through the snow, land diffuse reflection to the back of the photovoltaic panels, on the one hand, solar energy can be converted into electricity, on the other hand, the heat generated by the power generation process will melt the photovoltaic panels on the front of the snow. "Our base covers an area of more than 30,000 acres . Because of the low efficiency of manual clearing of large areas, the use of double-sided double-glazed photovoltaic panels can reduce snow cover and can effectively improve the efficiency of power generation in snowy days." "If a region's power generation is monitored to be abnormal, the operation and maintenance personnel can patrol the drone and combine it with infrared map analysis in order to locate the faulty PV panels and carry out timely maintenance." Wang Runsheng said, "This approach has a wider field of view and higher accuracy than manual patrols, and less than 10 people can complete the daily inspection and maintenance of the entire base project." Project data show that the photovoltaic base investment totalled 4.8 billion yuan, equipped with a booster station, electrochemical energy storage system, etc. Construction began at the beginning of this year, and nearly all of them are connected to the grid. It is expected to provide around 2.1 billion kilowatt-hours of green power annually, accounting for about 4.5 percent of Shihezi's 2022 power generation, equivalent to an annual saving of about 650,000 tonnes of standard coal. China's Xinjiang has abundant sunshine and solar energy resources. In recent years, Xinjiang to speed up the pace of photovoltaic industry layout, from equipment manufacturing, industrial support and other aspects of force, help solar energy resources into development advantages. As of early December, Xinjiang's new energy scale ranked first in the country.

  • German Economy Minister Plans Subsidies for Domestic Manufacturers
    December 18, 2023

    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.

  • Do You Know What Is The French ETN Certification for Racking Systems?
    October 09, 2023

    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.

  • DEYE: The Incident of German Micro-inverter Products Has Been Properly Handled
    December 11, 2023

    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.

  • Do You Know What A Micro-inverter Is?
    September 14, 2023

    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.
