A court in Beijing is now reviewing the filing. Risen Energy, Huawei and TuV Rheinland were among the companies and organizations that have joined the new 600W+ Photovoltaic Open Innovation Ecological Alliance, which was officially established on Thursday. Other participating companies include Flat Glass, Arctech Solar, Nextracker, JA Solar, Trina Solar, Datang, and Zhonghuan Semiconductor. China Huadian announced a tender this week for projects in fiscal 2020. The procurement exercise is for 2.04 GW of monocrystalline PV modules and inverters, with bids to be finalized by the end of this month.

Researchers at the Polytechnic University of Madrid have examined the feasibility of storing power generated by rooftop solar as heat which can then be used to generate power when the sun isn’t shining – ‘power-to-heat-to-power storage,’ or PHPS technology. The household system in Madrid studied by the scientists included a highly efficient, thermally-driven heat pump and solar thermal collectors. The ‘trigeneration’ system, or combined cooling, heating and power (CCHP) technology includes two types of heat store: a low or medium-grade one for domestic hot water and space heating and a high-grade heat store for combined heat and power generation. The heat generated in the former can be used for cooling as well as heating demand. A reference case was based on grid power consumption plus an electrically-driven heat pump for cooling. Factors The Madrid group said factors including the cost of grid power and fuel and the price and productivity of PV arrays would influence the optimal size of trigeneration systems. The researchers estimated a €900-1,200/kW cost for PV systems and based their estimate of PHPS profitability on the resulting electricity savings. A domestic power-to-heat-to-power storage system could drive grid electricity savings of more than 70%, according to the researchers, but would require 12-15 years to pay for itself. “This holds true even when the heat-to-power conversion [efficiency] is moderately low (20-30%), provided that the economic conditions are favorable,” the researchers stated. The Madrid group conceded heat losses in the high-temperature thermal store would mean a PHPS system would mean a solar power self-consumption rate of only 40-60%. “Possible ways of minimizing these losses include the development of novel, ultra-dense heat stores at moderately low temperatures, or more advanced thermal insulation [systems],” added the researchers. The group’s findings are described in the study Techno-economic analysis of solar PV power-to-heat-to-power storage and trigeneration in the residential sector,published in Applied Energy and on the Science Direct website.

Frompv magazine Germany. Interest in subsidy-free power purchase agreements (PPAs) for photovoltaic and wind power plants in Europe really took off last year – a development confirmed by an updated version of theStatus Quo: Market Parity of PV and Onshore Wind in Europereport published by German consultancy Enervis Energy Advisors. Analysts who crunched the data from 25 nations calculated a 21 GW pipeline of projects was being developed without subsidy in Europe at the end of 2019. Spain continued to lead the way, according to the Enervis report, with 4.39 GW of unsubsidized-PPA-driven projects announced last year. Italy followed, with 1.91 GW, ahead of Germany, with 1.05 GW. Demand also rose, however, in Portugal (444 MW), Denmark (338 MW) and France (158 MW) and Enervis predicted southern European markets will continue to be fertile territory for subsidy-free solar PPAs despite bureaucratic hurdles. For wind farms – on and offshore – north and north west Europe continue to be the focus. Wholesale prices Although the historic rise in wholesale electric prices in the EU halted last year – and has plunged during Covid-19 shutdowns – Enervis noted solar and wind power could be generated for up to €20/MW cheaper than market prices. With the coal withdrawal plans announced by some European nations expected to buttress the wholesale energy price in the medium term, according to Enervis, ever cheaper solar and wind projects will continue to make subsidy-free PPAs an attractive option. The updated report states the renewables business case will stand up even in the face of gas prices which fell 39% in 2019, year-on-year, and dragged down the wholesale electricity price 16% despite a 56% annual rise in the cost of CO2certificates. In terms of crowding out rival renewables technologies, instead of fossil fuels, the highest ‘cannibalization rate’ observed for solar last year was 12%, in Sicily. In Germany, onshore wind saw a 14% rate. Those rates could rise as renewables penetrate deeper into European grids, according to Enervis, which highlighted fluctuation in the price of fossil fuel-fired electricity as an unpredictable variable, which could be counterbalanced by higher CO2prices; less baseload generation; and flexible demand and storage shoring up the energy price.

Recently, the Saudi energy navigation company ACWA Power completed the Oman IBRI two phase 500MW photovoltaic project financing, and once again launched a deep cooperation with the sun power, strong joint assistance to build the largest photovoltaic power station of Oman. ACWA power pays special attention to the application of the latest technology route in this project, which requires the maximum reduction of lcoe; at the same time, it also puts forward high standard requirements for the reliability of equipment, so as to cope with the problems of Oman tropical desert climate, such as windy sand, strong wind erosion and large temperature difference. After comprehensive consideration, all customers finally choose the world's largest power 1500V series inverter SG250HX. The world's largest single unit power + high capacity ratio, with the best system cost SG250HX sets up the benchmark of the world's largest single unit power string inverter. With the same power station capacity, the number of inverters, low-voltage switchgear, cables and other equipment can be reduced. It is estimated that the initial investment cost of 100MW power station can be reduced zero point zero two Yuan / W or more. In addition, with the industry's higher volume ratio, support 6.75MW Large sub array design, PLC communication, integrated PID protection and repair functions and other advantages further reduce lcoe. Intelligent air cooling + the highest level of protection, reliable operation in high temperature and strong sand environment High temperature and strong wind sand are the strong enemies of reliable operation of the inverter.

On May 18, 2020, at the global photovoltaic large-scale technology conference, CORIGY SOLAR Solar released the third-generation 525W + high-power module product Deep Blue3.0 for the first time to the world. This product realizes ultra-high power 525W, conventional version modules The efficiency can reach 21%. CORIGY SOLAR Solar's director and senior vice president Huang Xinming said in a speech at the conference that large-scale application depends on the rapid decline in the cost of photovoltaic power, and behind it is the huge investment and unremitting efforts of countless photovoltaic companies in technology research and development. The technological innovation of module products is the most effective way for photovoltaic module companies to achieve cost reduction and efficiency increase. Monocrystalline modules are basically increased by 10 watts per year, and the efficiency is increased by 0.59%. After 2018, the rate of component power increase began to accelerate. It is understood that the current JA SOLAR module has reached the mass production level of 450W +. At the meeting, Tang Kun, director of CORIGY SOLAR Solar Product Technology Department, introduced the company's latest ultra-efficient component Deep Blue3.0, which uses 180mm silicon wafers, based on percium high-efficiency battery technology, and uses PERCIUM + ultra-efficient single-crystal battery technology. Greatly improved battery efficiency. Tang Kun said that after applying 525W + high power components to the power station, the benefits will be obvious. Taking a 360MW power station in Dubai as an example, the project simulates the use of flat single-axis + double-sided components. The results show that the power station using 525W components brings about 7.34% reduction in the cost of electricity per kilowatt hour compared to 400W. According to reports, CORIGY SOLAR Deep Blue3.0 high-power modules will enter mass production in the third quarter of 2020, with a total capacity planning of 14GW by the end of 2021.
