The country saw the addition of PV systems totaling 880,8 MW in the first two months of the year. Its cumulative installed PV power grew to 54.3 GW.

According to new figures published by Germany’s Federal Network Agency (Bundesnetzagentur), the total capacity of newly registered solar PV systems in Germany in February was 350.7 MW. This compares to 536 MW in January and 202.3 MW in February 2020.

Most of the February capacity–270 MW–comes from PV systems not exceeding 750 kW in size under the country’s FIT scheme.

The newly installed PV capacity for the first two months of the year was 880,8 MW and the cumulative capacity of all subsidized PV systems in Germany reached 54.3 GW at the end of February.

Starting from tomorrow, tariffs for PV systems will fall 1.4%. The FIT for rooftop systems of up to 10 kW capacity will fall under the €0.08/kWh threshold for the first time, to reach €0.0781/kWh. The payment for installations with a capacity between 10 and 40 kW will be €0.0759/kWh.

The European Union wants to provide €700 billion through its post-pandemic reconstruction program, but the European Solar Manufacturing Council says that €20 billion of the total should be used to shore up the European PV industry.

Europe was once the heart of the solar industry, but those times are long gone. Asian countries, particularly China, have since pulled ahead with gigawatt-scale production of PV products. The European solar industry has survived, thanks to small manufacturers, but there are also plans afoot for large-scale production on the continent.

The European Solar Manufacturing Council (ESMC) has determined that in 2019, only about 11% of silicon, 1% of ingots and wafers, 0.4% of solar cells, and 4% of solar modules were manufactured in Europe, accounting for 15% of global PV demand. Many solar modules must be imported and demand is currently rising in many European countries.

With this in mind, ESMC is now insisting that €20 billion ($23.9 billion) from the €700 billion EU Recovery and Resilience Facility should be used to support the growth of PV production in Europe. Around 37% of the funds are to be spent on clean-tech and EU member states will share their views on how the money should be used by the end of this month.

“The European photovoltaic industry suffers from a lack of strategic political priorities,” the ESMC said. Eicke Weber, the chairman of the organization, added that a strong PV manufacturing industry will ensure resiliency. “By energetically reversing the situation and giving the PV industry the opportunity to supply the European market, Europe can regain control of its energy transition,” said Weber.

The pandemic has shown that Europe should not remain overly dependent on material imports. It is of strategic importance for countries to have regional and local PV value chains. The ESMC has stated that at least 75% of PV demand in Europe should be covered by domestic production. Two-thirds of PV products produced in Europe should be exported, it said.

This would mean building up 60 GW of manufacturing capacity in Europe by 2026. The current trade deficit of €10.5 billion in solar cells and modules could be converted into around €50 billion of PV production on the continent. This would also create around 178,000 new jobs in Europe.

Based on the current market situation, there is an excellent time window of two to four years to rebuild a competitive photovoltaic production chain, as a global technological change from PERC cells to other technologies such as heterojunction or TOPCon cells is taking place.

The photovoltaic module assembly line has a yearly capacity of 100MW, soon to be increased to 200MW, and it has the capacity to produce the latest technology modules.

Prof. Noureddine Yassa, Chief Executive of the “Commissariat des Énergies Renouvelables” of the Prime Minister’s Office in Algeria has inaugurated the Milltech photovoltaic module assembly factory, in Constantine, Algeria, on the 8th of March 2021. The production line has been supplied by Mondragon Assembly and commissioned in February 2021.

Prof. Noureddine Yassa was impressed by the high quality and highly automated factory where Mono Perc modules with 22.5% conversion efficiency were instantly manufactured under his eyes by fully trained Algerian engineers. Knowing that Prof. Yassa is originated from the German Solar Industry, Milltech CEO Mr. Hammoud said “we are honoured to receive such comments and we are encouraged to build further momentum”.

A new step for Mondragon Assembly in the MENA region

Since it began developing projects in the MENA region, Mondragon Assembly is consolidating its position as a technological partner for its clients, as it not only offers solar module manufacturing lines but also provides support throughout the entire life of the project, where it ensures the technological evolution and maximum quality of the PV modules it manufactures.

KARPAT SOLAR, the Romanian company, has signed an agreement with MONDRAGON ASSEMBLY to supply a production line for photovoltaic solar modules with a capacity of 100 MWp per year.

KARPAT SOLAR has its facilities in the historical region of Transylvania, in the heart of Romania and has ambitions to become the first module manufacturer in Romania. These 100 MW modules are the first phase of a large-scale project that will initially manufacture for the local market but is targeting the European Union.

Mr Csomor Karoly, CEO of KARPAT SOLAR: “we hope to have our facilities in full production before summer, which will allow us to tackle the Romanian market in autumn 2021, in this first phase. Currently, the use of renewable energy is growing exponentially in our country and we at KARPAT SOLAR intend to make our small contribution in this regard. We will locally manufacture high-efficiency modules under the strictest quality parameters”.

Mr. Igor Herrarte, International sales manager at MONDRAGON ASSEMBLY: “This project shows that the European trend to promote alternative energies is a fact. In 2021 we will see how several module manufacturing projects materialise in Europe. They will be projects of a different nature, both in size and in manufactured product. We also expect technological diversification. In addition to the standard modules, we will see companies launching modules for HJT, BIPV and other niche products suited to European demand, where Mondragon Assembly has the solution all those new technologies”.

New gas generation capacity reaches 1.8 GW could be replaced by 1.7 GW of solar as part of a cleaner, 6.3 GW collection of renewables and energy storage facilities–and that alternative already comes in cheaper than the business-as-usual approach, according to the Carbon Tracker thinktank.

The cost of developing the 6.3 GW-capacity mix of clean energy assets Carbon Tracker estimated would be necessary to replace a 1.8 GW gas generation plant fell to the same price as the fossil fuel asset in 2020: £60/MWh (€69.93), according to a new report from the thinktank.

And solar would play a significant part in such a clean power portfolio at today’s prices, according to Carbon Tracker, with each 1.8 GW of new gas capacity planned by the U.K. government requiring 1.7 GW of solar panels as part of the alternative, non-fossil-fuel power mix. The clean energy portfolio modeled by Carbon Tracker included 1.7 GW of energy storage facilities–contributing half the overall cost, at today’s prices–with onshore wind generation, demand-response technology and energy efficiency investment completing the line-up.

The low, 11% capacity factor of solar the energy output actually delivered as a percentage of nameplate generation capacity–means PV would contribute around 26% of the electricity required to supplant a gas turbine, falling to 1% during periods of peak demand, based on an even mix of residential and industrial power consumers. During peak periods, the 27% year-round-average share of the burden provided by energy storage would rise to 39%, with demand-response’s contribution rising from 20% to 23%, as onshore wind falls from 18% to 10%. The energy efficiency investment opportunity offered by the U.K.’s aging housing stock means the contribution from that source–during the annual peak electricity demand periods, which occur in winter–would rise from 9% to 27%. However, the dismal failure of Westminster to deliver on its flagship green home improvement policy last year would cast significant doubt on the government’s ability to guide energy efficiency investment effectively.

Research processes to harness an oxygen redox reaction in certain cathode materials for lithium-ion batteries have been a success. Scientists in the UK developed a model to explain one of the challenges to harnessing an oxygen-redox reaction in certain cathode materials for lithium-ion batteries. Based on their improved understanding of the reaction, they suggest several possible routes for further research to avoid unwanted reactions and develop reversible, high energy density cathode materials.

However, when integrated into a battery, such cathode materials undergo irreversible structural changes upon the first charge, immediately reducing their subsequent voltage.

The mechanisms behind these structural changes have puzzled scientists and held the materials back from further development. With this in mind, the UK’s Faraday Institution set out to observe the structural changes to these cathodes in action.

Lithium-rich cathode materials have been an area of interest for scientists working in energy storage since the early 2000s. In these materials, an oxygen-redox reaction has been shown to store additional charge in oxide ions, as well as in the transition metal ions – potentially boosting the material’s storage capacity.

The former need not necessarily relate to conventional lithium-ion batteries, however, as a recent webinar staged by Solarpower Europe and EU body GET.invest discovered.

A gravity-based energy storage project in Sudan was among the projects considered in a recent webinar hosted by trade body Solarpower Europe and EU decentralized renewables program GET.invest, which examined the potential for solar to drive electricity access in sub-Saharan Africa.

With electrification not proceeding fast enough to meet the UN ambition of universal energy access by 2030, solar could offer a fast-track solution, according to Yasir, particularly when installed with the help of innovative business models. “Off-grid renewable energy technologies represent a cost-effective, environmentally sustainable, rapidly deployable and modular tool to accelerate the pace of electrification,” said IRENA’s program officer for decentralized renewable energy.

Ali Yasir, of the International Renewable Energy Agency (IRENA), examined the role solar can play in reaching the UN sustainable development goal of universal energy access, in particular through its deployment in humanitarian and healthcare settings.
