• Send photovoltaic power back to the grid
    August 17, 2021 Send photovoltaic power back to the grid
    Australia's new regulations: charges will be levied for sending photovoltaic power to the grid Recently, according to new regulations introduced by the Australian Energy Market Council (AEMC), power companies will soon be able to charge owners who use rooftop systems to deliver electricity to the grid. The plan to allow the levy of Internet access fees was mentioned in the draft decision in March, and a final decision was made recently. At present, about 20% of customers use rooftop solar power systems to partially meet their power needs, compared with only 0.2% in 2007. It is expected that this number will double in the next two decades. Benn Barr, CEO of AEMC, said that household users sell excess electricity back to the grid, which puts increasing pressure on systems that are not set up to be two-way. Welfare groups supported this change, but were opposed by some solar owners when it was first announced. AEMC stated that it had “listened to feedback” and “strengthened consumer protection”. Barr said that the reform requires the grid to assume the obligation to obtain electricity from residents' homes. They will not be able to collect fixed fees and will only charge fees when the grid is congested. AEMC stated that power suppliers will be able to develop a series of packages for consumers to choose from, but they must include "free basic services." But Barr said that because of the potential rewards, many people will find it financially better to choose the paid option. AEMC said that household batteries provide one such option because battery owners can "store energy and send it to the grid when the price is higher." The so-called "congestion" in the grid is increasingly forcing power companies to prevent households from feeding back the electricity generated by solar energy to the grid. The new rules will prevent grid companies from completely banning this situation. "You see these export bans in Victoria, when people want to connect to the grid, they are told they can't connect to anything," Barr said. "It really cost them, and it prevents us from decarbonizing the industry faster. We hope to get more solar energy in the system, especially smart solar energy." These reforms are a response to Australia’s changing energy landscape and growing use of solar energy. Power generators and regulators face the eternal challenge of balancing supply and demand changes. A quarter of Australian households have rooftop solar power systems-one of the highest percentages in the world. Last year, South Australia became the world's first major jurisdiction entirely powered by solar energy. In more than an hour on October 11, the rooftop solar system alone could meet 100% of the energy demand. Modeling by AEMC found that in the worst case, existing solar customers can still get 90% of their current income without changing their consumption behavior. Proposals for regulatory changes come not only from the distribution company SA Power Networks, but also from we...

  • Strong recovery expected for European PPA market in 2021
    October 08, 2020 Strong recovery expected for European PPA market in 2021
    In 2020, around 12 GW of unsubsidized photovoltaic and wind power projects were announced in Europe, according to German consultancy Enervis. Compared to 2019, there was a decrease of around 50% in PV projects and a 30% drop in offshore and onshore wind parks, according to the updated analysis document Status quo: Market Parity Report of PV and Wind Onshore in Europe. According to the analyst, Spain remains the largest market for solar PPAs, with a project pipeline of 2.18 GW, which represents more than half of the announced subsidy-free photovoltaic projects in Europe. Germany and France are the second and third largest markets with 786 and 392 MW, respectively. The main reason why the PPA market, which was just gaining momentum in Europe, was massively slowed down, at least temporarily, in 2020, was the coronavirus pandemic and its effects on the electricity markets. When the first lockdowns began, in March 2020, wholesale electricity prices plummeted, although they recovered over the course of the year. Across Europe, there was a decline of 25% over the course of the year. Furthermore, the gas price has fallen by a further 31%. After strong increases for CO2 certificates in 2018 and 2019, the Enervis analysts recorded a stagnation for these prices for 2020. As for the electricity futures, there were already signs of a significant recovery in December 2020, in some cases at a higher level than before the crisis. Enervis also reported that capture prices for photovoltaics and wind power also fell drastically in the past year. In Germany, for example, the capture price of solar fell, on an annual average, to around €0.0246/kWh, while it was €0.043/kWh in 2018. These higher values make it difficult to secure a PPA as the projects are difficult to refinance through electricity sales. However, the analysts expect a short-term recovery in capture prices. However, the relative capture price of photovoltaics decreased significantly in 2020, which was also influenced by very low gas prices. Enervis saw a significant, increasing presence of negative electricity prices in European countries. In Germany, these were reported 298 times within a year while, in the previous year, there had been 211 occurrences. In many other countries, there were negative electricity prices for the first time, in 2020. The main cause is strong electricity injection from renewable energy systems with a simultaneous sharp drop in demand as a result of the coronavirus lockdown. Negative electricity prices, on the other hand, have a dampening effect on the capture prices, as the plant operators cannot generate any income during these hours. “An increasing number of European markets [have] the potential to achieve market parity in the next few years, despite temporarily lower capture prices due to the pandemic in 2020. Risks and opportunities of investing in a subsidy-free renewable energy project should be carefully analyzed,” said Enervis analyst Franziska Sicker.

  • Jordan Photovoltaic Project
    August 09, 2021 Jordan Photovoltaic Project
    Chinese enterprises undertook the construction of the Jordan photovoltaic project started Construction of the Jordan Dishi 24MW photovoltaic project undertaken by Shandong Electric Power Construction Third Engineering Co., Ltd. has started construction recently. This is the first photovoltaic power plant project undertaken by a Chinese-funded enterprise in Jordan. Project civil engineering manager Hou Xiaobing told reporters on the 5th that the project is located in the desert area of southern Jordan, which is rich in sunlight resources. The estimated construction period is 270 days. The project consists of a 24 MW photovoltaic power station, using double-sided photovoltaic modules with tracking support technology, and installed more than 60,000 photovoltaic panels. After the completion of the project, the Chinese company will also be responsible for two years of operation and maintenance. Zheng Hongzhi, the Chinese project manager, said that the use of Chinese photovoltaic power generation equipment and technology in the project will create a large number of local employment opportunities. Sudan, the project leader of the Jordan Water Authority, the owner, said that the power station was built near a water plant managed by the Water Authority. After the completion of the power station, it will not only better meet the electricity demand in the surrounding area, but also greatly reduce the electrical power of the water plant, increase the water supply capacity of the water plant, and help reduce local water prices. Jordan currently relies on imports for a large amount of energy and is also one of the most water-scarce countries in the world.

  • Silicon-carbide inverter for medium-voltage grids
    September 08, 2020 Silicon-carbide inverter for medium-voltage grids
    Germany's Fraunhofer Institute for Solar Energy Systems (ISE) has developed a 250-kW silicon-carbide (SiC) inverter that can be used in utility-scale PV projects connected to a medium-voltage grid. Compared to a standard PV inverter with silicon transistors, the creators of this SiC device claim it eliminates the need for a 50 Hz transformer when PV installations are linked to medium-voltage networks. The inverter was built with 3.3-kV SiC transistors that have lower power losses than standard silicon transistors. “This makes it possible to operate the inverter stack with a switching frequency of 16 kHz,” the Fraunhofer scientists specified. “With state-of-the-art silicon transistors, only about 10 times lower switching frequencies are possible in this voltage class.” According to the scientists, the device has a higher switching frequency, which results in a smaller format of the passive components. Fraunhofer ISE's inverter was also equipped with an active liquid cooling technique, where a liquid synthetic ester is pumped into the device to cool the transistors. “At the same time, the cooling medium for the filter chokes serves as an electrical insulation medium, allowing the filter chokes to be made even more compact,” the researchers further explained. The inverter runs at 98.4% efficiency and can be installed in a modular interconnection of multiple inverter stacks, which makes it ideal, according to its creators, for the deployment of systems at megawatt scale. “Taking into account additional installation space for switchgear and cooling unit, a volume saving of the inverter system of up to 40 percent can be achieved compared to commercial inverter systems of this voltage class,” the research institute stated. These inverters, which the scientists define as “high-blocking SiC devices,” can have a wide range of applications in the medium-voltage range. “Especially for large photovoltaic power plants, the trend is towards higher and higher voltages,” affirmed Andreas Hensel, Head of Team Medium Voltage Power Electronics at Fraunhofer ISE. Silicon carbide-based inverters are known for providing higher power density and having less need for cooling, which results in lower overall system costs than traditional inverters based on silicon transistors. However, defects at the interface between the silicon carbide and the insulating silicon dioxide material are still a major barrier to bringing the technology to mass production. German inverter manufacturer Kaco new energy, a subsidiary of German industrial conglomerate Siemens, unveiled two SiC string inverters for applications in large-scale PV projects in December. Other inverter makers have thus far developed silicon carbide devices only as prototypes or in small-scale production runs.

  • Global actions delivering electricity for rural households through off-grid renewable energy
    August 28, 2020 Global actions delivering electricity for rural households through off-grid renewable energy
    The International Energy Agency (IEA) estimates that 548 million people in SSA currently have no access to electricity in their homes. Over the last two decades, the rate of rural electrification has been rapid due to grid extension programs in Asia, Latin America, and parts of Africa. Yet in many regions, geographic variables and low rural population density make grid extension too costly a method to provide electricity access for every household. In order to fill the gaps, governments and development organizations have used off-grid solutions to provide rural households and villages with access to electricity. One of the ways in which rural electricity access has been addressed through off-grid renewable energy solutions is through a market-based approach, which centers on the role of social enterprises (SEs). Such SEs have concentrated their efforts in rural areas of Sub-Saharan Africa, Latin America, and South Asia where poverty rates are high and grid connection is unlikely in the medium or long term. There are numerous SEs whose objective is to provide poor rural households access to affordable solar home systems (SHSs) and pico-solar lights for lighting and charging cell phones. These include SunnyMoney, Ilumexico, Azur, as well as many others. SEs’ efforts have been notably helpful in SSA, wherein 2018, it is estimated that 25 million people receive household electricity access through SHSs and pico-solar lights purchased from SEs. A 2017 report by Acumen Solutions examined the major challenges preventing the scaling of this method in SSA, finding that up-front costs, lack of availability in terms of finance and selection, as well as lack of knowledge of the product have prevented more rural households from purchasing SHSs or pico-solar lights. The report also identified and evaluated various strategies used by SEs to alleviate these barriers. In order to alleviate the barrier of up-front costs, SEs have offered different payment plans, such as rent to own (households make periodic payments that eventually lead to ownership), perpetual leasing (households pay for electricity consumption but never own the product), and mobile money payment systems. SEs have also utilized other strategies to increase access and publicize their products for furthering adoption. For example, in Senegal, SunneyMoney has utilized a “Lighting Library” model, which allows students in rural schools to rent pico-solar lights and small SHSs for cellphone charging. Through this model, SunneyMoney found that 35% of families in the targeted schools eventually purchased a product, compared to only 12% in other schools where this was not offered. This approach has helped disseminate increased knowledge regarding off-grid renewable energy solutions in poor-rural areas of Senegal. However, it may be difficult to replicate this intervention, as it required a high amount of initial investment, indicating that outside financial support may be needed for scalability.

    March 08, 2021 Spain's latest round of photovoltaic auctions has the lowest price of 0.01498 euros/kWh, a record low in recent years
    Spain's latest round of photovoltaic auctions has the lowest price of 0.01498 euros/kWh, a record low in recent years The Spanish government stated that photovoltaic developers received approximately 2.04GW of capacity, and wind farm developers received 998MW of capacity, with a total allocated capacity of 3.03GW. The lowest price for solar projects is €0.01498 ($0.018)/kWh (about 0.018 USD, the highest price is €0.02890/kWh, and the average price is €0.02447/kWh. The lowest price for wind power generation is €0.020/kWh. The lowest price of solar energy is only one-third of the auction price of renewable energy in 2017. The average price of solar energy is 80% lower than the average price of the auction in 2017, reaching the lowest level in the history of Spanish photovoltaic technology auctions. However, this lowest price did not exceed the €0.01120/kWh price recorded in Portugal in the latest auction, or the auction price in Abu Dhabi in July last year.
