Energy production is one of the many factors leading to climate change, but given the necessity of energy, more progress is needed to make the process of entering the era of space-based energy more sustainable.      This is not a new concept, but recent developments have made it easier to become a choice - the answer to space-based energy or a clean Earth.     But what is space-based energy and what does it mean for the future?     With the help of Northern Power Grid Company, we are here to tell you what you need to know. What exactly is space-based energy?     Thanks to advances in technologies such as ultra-light solar cells, space-based energy is a sustainable way to obtain energy.     By using solar modules, reflectors and mirrors installed in space, solar energy can be collected. This allows solar radiation to be directed towards components, transmitted to Earth, forming space-based energy that is then converted into electricity.     Therefore, regardless of the weather and time of the year, energy can be produced in a clean and renewable manner, achieving a more sustainable future.     Due to the ability of this process to generate a large amount of energy, space-based energy may outperform other energy sources in addressing climate crises.      Energy production is one of the many factors leading to climate change, but given the necessity of energy, more progress is needed to make the process of entering space-based energy more sustainable What are the benefits of space-based energy?     There are many advantages, but one of the main benefits is that it can continuously generate electricity. Space-based solar power stations can be powered by the sun 24/7, making them a more efficient energy conversion method than existing terrestrial solar power systems, which depend on time and weather.     The global demand for energy is expected to grow by 47% by 2050, making sustainable energy absolutely crucial. The demand for power connections will continue to exist, so space-based energy can provide a cleaner power solution, which is a significant advantage. In fact, this power source method will generate 0% of greenhouse gas emissions, which can meet the demand for energy while preventing damage to the Earth.     Another benefit we can achieve through space-based energy is reducing land use. For solar energy, although it is another sustainable power supply method, it also has some environmental impacts. Changing sunlight exposure is only one of the impacts of solar energy installations, as it can prevent rainfall in some areas and affect plant growth. However, this is not an impact caused by space-based energy, therefore space-based energy is a more reliable source of electricity. What is the future of space-based energy?     On a global scale, space-based energy has made many progress, and the high ...

Project Overview:     In the 30MW photovoltaic power plant built by Guodian Power in Jizhou District, Tianjin, we conducted a comparative study on the power generation performance of bifacial photovoltaic modules equipped with TOPcon and PERC cell technologies. The project is located in Jizhou District, which belongs to the warm temperate semi humid continental monsoon climate. It has four distinct seasons, abundant sunshine, abundant heat, high temperature and rain in summer, and cold winter. The total annual solar radiation amount reaches 1450~1600kWh/m2 (5220~5760 MJ/m2), and the light resource conditions are excellent, which is conducive to the development and construction of photovoltaic projects. Project Design:     The project has a rated capacity of 30MW and consists of 12 2.5MW photovoltaic power generation units. Each string is designed to consist of 26 components, and every 17 strings are connected to one string inverter. Each power generation unit is equipped with 11 225kW string inverters and 1 2500 kVA box transformer, with a capacity ratio of 1. The bracket selection is fixed, with an inclination angle of 30 °. The vertical two row bracket scheme is adopted, and the minimum height of the component from the ground is 0.5 meters. In order to visually compare the power generation differences of N/P type components under actual operating conditions, the project installed a total of 20MW of P-type double glass 545 components, and a total of 10MW of N type double glass 560W components. result:      Based on the power generation performance advantages of N-type TOPCon components such as lower temperature coefficient, higher double-sided rate, and lower photo induced attenuation, compared to conventional P-type PERC components, it can bring at least 3% power generation gain under the same DC side capacity. Based on actual situation analysis, due to the high summer ambient temperature in the climate zone where the project is located, the extreme high temperature can reach 40 degrees Celsius. After considering the heating up of the module itself, the operating temperature of the module can reach nearly 60 degrees Celsius. A better temperature coefficient of the module can reduce the impact of temperature on the output power of the module. The Tiger Neo series module equipped with TOPCon technology battery cells has a temperature coefficient as low as -0.29%/℃, which will effectively improve the power generation of the module under the same working conditions. By comparing the power generation of an N-type component array with two P-type component arrays, it was found that compared to conventional P-type PERC modules, the single kilowatt power generation gains of the Jingke N-type TOPCon module reached 5.02% and 5.15%, respectively, strongly supporting the excellent performance of the N-type module in practical outdoor applications. Conclusion:     Based on the comparison and analysis of the si...

    If Portugal wants to achieve its target of 9GW of installed capacity ahead of schedule by 2026 rather than by the end of the century, it will need to address one of the main obstacles it currently faces: licensing issues.     At this week's European Large Solar Conference, team members discussed the future of the Portuguese solar market, which has undergone some regulatory improvements, including less stringent environmental assessments for projects under 100 hectares to help accelerate the deployment of solar photovoltaic, but more work needs to be done.     "We need faster and smoother licensing," said Pedro Pereira, General Manager of Eurowind Energy in Southern Europe. Pedro Amaral Jorge, CEO of the Portuguese Renewable Energy Association (APREN), said that in 2018, Portugal had only 5 GW of application capacity waiting for licensing. By the end of 2020, this number has sharply increased to 250GW.     In addition, Amaral Jorge stated that Portugal's National Energy and Climate Plan (NECP), released in 2019, may revise its goal to increase the installed capacity of solar photovoltaic from the current 9 GW to 15-20 GW by 2030.     Jo ã o Amaral, Chief Technology Officer and Country Manager for Portugal at Voltalia, added that as the demand for newer renewable energy applications increases, the government needs to provide licenses for these new projects and withdraw capacity projects that have not yet been implemented.     At the end of 2022, the installed capacity of solar photovoltaic in Portugal was 2.6GW, with an increase of 446MW in large public projects and 385MW in small and medium-sized projects in the same year alone. As shown in the figure below, by the end of July, Portugal had exceeded the full year figure for 2021. Miguel Lobo, Portugal's national head of Lightsource BP, said that so far, Portugal needs to double its installation rate to achieve the target of 9GW of solar photovoltaic installed capacity by 2026. This plan is meaningful for a country with the best solar radiation in Europe. Compared to other European markets, Portugal's production capacity has increased by 50%.     Most panel members believe that licensing is one of the main issues currently facing the Portuguese market, while insufficient grid capacity is another major bottleneck for Portugal to achieve ambitious renewable energy growth by 2030.     Renato Madureira, Country Manager of FF Ventures Portugal, said, "The main problem we are facing is a lack of capacity, and we do not have the capacity to connect to the grid." This issue not only affects newer projects, but also projects signed in previous tenders.     For old projects that are already waiting to be connected to the grid, in order for Portugal to achieve its goal of new renewable energy capacity by the end of this century, it is necessary to consolidate the grid and do more work.     Amaral add...

A solar system the size of two football pitches on Bella Center's roof will in future cover a third of Bella Center's electricity consumption. The 550W solar panel will be the largest of its kind in Zealand. Zealand's largest roof-integrated solar system now sees the light of day on top of the Bella Center in Copenhagen. When all solar cells are connected, the on grid solar system has a capacity of 2.79 MW. This means that the solar cells can produce green energy equivalent to the annual electricity consumption of 537 households with two adults and two children. The solar cells are part of the sustainability strategy of Bellagroup, which owns Bella Center, and which has long worked with initiatives that can reduce energy consumption in the group's hotels and venues. Earlier this year, the new Bella Arena received certification for being sustainable construction in international gold class. Now you take the next step and start producing the energy yourself. "It is quite obvious to utilize the many flat roofs in the big cities to create green energy, and there are not many people who have as large a roof area as we do. We work purposefully with sustainability and responsibility across all our hotels and venues as part of our "responsible hospitality" strategy. We are therefore very excited that we can now utilize the roof's potential to generate renewable energy for the Bella Center and AC Hotel Bella Sky," says Christian Folden Lund, CEO of Bellagroup. Leading the way in the development of responsible hospitality The Bella Center is already one of Europe's most ambitious convention centers when it comes to integrating climate and environmental considerations and social sustainability into production. With the solar cells, Bella Center takes another step in the green direction with its own production of green electricity corresponding to just over a third of the center's electricity consumption in 2021. "The climate footprint is an important parameter when our customers have to choose where their large international conferences will take place. Copenhagen is already known as a green choice, and we would like to expand that position. As Northern Europe's largest conference venue, we would like to be at the forefront of the development of future responsible hospitality. We are taking a huge step with the new solar cell system, but we are constantly looking at how we can keep improving," says Christian Folden Lund. Bellagroup is also replacing 5,500 light sources at AC Hotel Bella Sky with LED lighting in 2023. Together with the establishment of the new solar cell system, it reduces Bellagroup's Co2 emissions by more than 400 tonnes annually. Most ambitious solar project in Zealand It is the company NRGreen that is establishing the new solar cell system on the roof of the Bella Center. It will cover an area of 16,000 m2, which is comparable to two large football pitches. And nothing like it has been seen in Zealand. "It is the largest and most am...

In 2022, Germany added 7.18GW of solar energy system, 2.14GW of onshore wind and 342MW of offshore wind. Net additions were stronger than in 2021, but still far below the pace needed to meet the 2030 renewable energy targets. According to data released by the Federal Network Agency, by the end of 2022, Germany will have 66.49GW of solar system capacity in operation. In order to achieve the target of 215GW in 2030, Germany needs to install 1.54GW per month on average. More than half of the new capacity, around 4.4GW, came from rooftop projects and 746.7MW from unsubsidized ground-mounted solar panels. Bavaria was once again the leader in new solar capacity, adding 2.09GW for all of 2022, bringing its total to 18.3GW at the end of the year. The North Rhine-Westphalia state came second with 899.2MW of net installed capacity, followed by Brandenburg with 794.1MW. In terms of onshore wind power, Germany's operating capacity by the end of the year was 58.2GW, and December witnessed the highest monthly growth rate of 309MW in the year. Despite an acceleration by the end of 2022, the rate of expansion would have to increase to an average of 591MW per month, so that by the end of the decade Germany's onshore wind turbines would reach 115GW. In terms of offshore wind power, as many as 38 offshore wind turbines (totaling 342MW) were integrated into the German grid last year, bringing Germany's wind power capacity in the North Sea and the Baltic Sea to 8.12GW.
