The World Future Energy Summit 2020 kicked off at the Abu Dhabi National Exhibition Center in United Arab Emirates on January 14, 2020 with the theme of “Rethinking Global Consumption, Production and Investment”. Hosted by Masdar, the Summit keynotes were presented by heads of states, members of the GCC royal families, global decision makers of clean energy enterprises and industry experts from all over the world.

At the Future Sustainability Summit, Li Zhenguo, Founder and President of LONGi, delivered a keynote speech which discussed various issues such as the development of new energy, the industry trends of future energy technology, global energy policies, cooperation in R&D and the pursuit of the best renewable energy solutions.

“With the development of the global economy, clean energy plays an important role in our daily life. We firmly believe that ‘Photovoltaic + Energy Storage’ is the ultimate energy solution for the future, and a powerful force in the fight against climate change and to achieve sustainable development,” said Li Zhenguo, Founder and President of LONGi. “With continuous technology innovations, we believe that solar energy will become the most economical power source in most regions of the world in the next 2-3 years. When the cost reaches parity, the transition of traditional energy to clean energy will begin on a large scale.”

“In the Middle East, water and agriculture are constrained by ecological and environmental elements. The use of solar power could solve the problems of electricity and energy consumption, and greatly reduce the cost of seawater desalination. Once there is sufficient fresh water, the problems of agriculture and food shortages will be eliminated. This is the benefit Solar for Solar brings. ” Li Zhenguo added.

The engineering and technology group Sener is a supplier of photovoltaic technology in Meteogune, a Meteo For Energy project installed at the Alava Technological Park (Basque Country, Spain) and inaugurated on Monday, 25 November.

Specifically, Sener has installed three single-row Sener PV trackers at this experimental plant. This mechanism is responsible for positioning photovoltaic modules with the aim of making an optimal use of solar radiation. Meteogune is in fact the first photovoltaic plant to feature SENER PV trackers, a technological development by SENER based on the experience acquired by the company in solar facilities around the world.

Aimed at reducing investment costs in photovoltaic power plants and with extremely high precision features, this product is part of a family of trackers for photovoltaic plants, known as Sener PV trackers, that includes single-row (used in Meteogune) and multi-row trackers (with up to 15 rows) that provide tracking along a single axis with a 2P configuration (2 modules in portrait array). Specifically in Meteogune, each solar tracker, with tracking along a horizontal single axis, covers an area of 160 sqm consisting of 80 photovoltaic modules with a total length of 40 m per row.

This Sener technology is therefore key to the performance of the photovoltaic power plant, which in addition to being an experimental plant (to test innovative technology, both the SENER PV tracker and a tracking optimization implemented by Meteo For Energy) will be used to supply a third of the power consumed by buildings E6 and E7 of the Alava Technological Park. Specifically, thanks to its solar tracker, the plant will produce 25% more energy than other fixed plants.

Driven by the start-up from Alava Meteo for Energy, which is engaged in weather forecasting and producing energy to improve the management and profitability of renewable energy plants in different parts of the world, the Meteogune plant aims to promote and digitize photovoltaic technology through R&D&i developments. This will allow conducting research and development activities in sensor systems, data analysis and artificial intelligence applications within the energy sector.

At Digital Solar & Storage 2019, SolarPower Europe launched a new report on solar mobility, thought to be the first of its kind, which explores the potential of clean mobility solutions and solar power. The report documents various solar mobility business models, illustrating the experience of European and global pioneers with detailed case studies. Three solar mobility models are highlighted: (1) solar-powered mobility, (2) solar smart charging, and (3) vehicle-integrated PV, all of which can lead to vast carbon reductions in the transport sector.

Decarbonising the transport sector, responsible for one quarter of European CO2 emissions, is a crucial step in achieving the European Union’s goal of carbon neutrality by 2050. Electrification, direct and indirect, appears clearly as the fastest and most cost-efficient technological solution to decarbonise transport. EV battery costs have achieved important cost reduction in the past years, with prices decreasing by 85% between 2010 and 2018, allowing the Total Cost of Ownership (TCO) of small and medium electric vehicles to be the same as conventional vehicles by 2024. Technology improvements and investments in fuel cells and electrolysis technologies have enabled a reduction in vehicle and fuel costs that could support the future cost-competitiveness of indirect electrification for certain segments of transport.

The electrification of transport makes even more sense when done in parallel with the deployment of renewables in the EU electricity mix. Without significant additons of renewable capacities in Europe, the full potential of electrification to reduce CO2 emissions in transport cannot be harvested. A study from the Paul Scherrer Institute shows that electric vehicles charging on fossil fuel-based electricity (e.g gas or coal) do not lead to an optimum reduction in CO2 emissions compared with conventional gasoline and diesel cars, while the CO2 emissions decrease by 50% with electric vehicles driving on CO2 -free electricity. The electrification of transport must therefore be thought of in synergy with the deployment of renewables in the power mix.

Solar energy is the ideal candidate to fuel green, electric mobility. As an illustration, in light road transport only, a typical rooftop, 5-kW PV module can easily produce the daily amount of electricity needed for the average commute of an electric vehicle, even though the adequacy of the PV system will depend on its geographical location and on time variations, including seasonal.

Solar energy is also a cost-competitive fuel for transport. It has achieved important cost reductions in the past years. The LCOE has reached €0.04/kWh worldwide and keeps decreasing, as a result of decreasing manufacturing costs and increasing cell performance. The deployment of solar can therefore support a cost-efficient energy transition with limited public support. Furthermore, in many countries, direct sourcing of solar energy is already cheaper than grid electricity.

Solar installations are modular and can adapt perfectly to the energy needs of the end-consumer or various means of transportation. Small solar installations can therefore fit well in urban landscapes, on rooftops, parking lots, rail infrastructure, etc. and can be installed as close as possible to the consumption point, be it a charging point or a refuelling station, thereby reducing reliance on the power grid.

Looking at the physics, solar is complementary to electric mobility, particularly in certain use cases like day charging at work places or combined with battery capacity at home. Solar has a predictable generation curve and produces electricity during the day. This PV generation curve matches well with the time at which the majority of electric vehicles are parked and can be charged, for instance at workplaces or public parking – a match that can be optimised with smart charging devices. Solar generation also matches perfectly the load curve of trains, trams or metros that run and consume energy during the day, making them good candidates for solar consumption.

Finally, recent surveys show that solar is the most popular source of energy and can support the public acceptance for sustainable transport policies. In Europe, solar has the highest level of support among citizens. Solar empowers consumers to invest into their own energy transition and gives them a sense of independence. As a result, one can easily observe the mutually reinforced dynamic between solar energy and electromobility: a recent survey by EuPD Research on electric-mobility has shown that for 77% of the respondents, the main reason to purchase an electric car was to charge it using their own solar energy, making it the most important motivator for purchase.

The synergies between solar and clean mobility can unlock significant benefits to accelerate the European energy and transport transition. The solar industry must therefore be imaginative and forward-looking to exploit these synergies and offer solutions to consumers that wish to drive on solar energy.

The benefits of solar mobility are vast, and include significant improvements in air quality for European citizens, as well as the reduction of noise pollution. Smart mobility strategies that rely on the increasing deployment of solar energy can lead to a more affordable and reliable solar electricity supply. This has the effect of optimising grid integration of future vehicles, unlocking new flexibility sources, and ultimately creating new business models for solar prosumers, EV owners, and charging station operators. Further, solar mobility and all of its related technologies can help Europe lead the global energy transition.

This aim of the report – the first of its kind developed by SolarPower Europe’s Solar Mobility Taskforce – is to look at existing and promising business cases of solar mobility and draw a first benchmark of renewable mobility models. It features existing case studies and pioneering projects.

Fotowatio Renewable Ventures (FRV), part of Abdul Latif Jameel Energy and a leading global developer of renewable utility-scale projects, has announced the financial close for Potrero Solar (296 MW dc), the Company’s second solar farm in Mexico.

FRV reached financial close last March with the International Finance Corporation (IFC) and Banco Nacional de Comercio Exterior (Bancomext), and it is expected that the plant which began construction in late May, will be completed by mid- 2020.

Potrero Solar is FRV’s first project in Mexico to be financed before having any of its products (energy, CELs or capacity) committed in the tender schemes, and one of the largest merchant PV projects worldwide. It is also one of the world’s largest PV projects to use bifacial technology. Once operational, the plant will trade the electricity generated as well as the associated clean energy certificates at the country’s energy market.

With an approximate area of 700 ha, Potrero Solar will be located in Lagos de Moreno, in the state of Jalisco, and will use bifacial PV modules, a new technology that has the ability to capture both direct sunlight from both the front and reflected light from the rear side.

The solar power farm will generate around 700 GWh of clean energy each year, enough to supply around 350,000 average Mexican homes and reduce the emission of 345,000 T/year of CO2. In addition, Potrero, which will be built by a consortium formed by multinationals Power China and Prodiel under an EPC contract, will boost the economic development of the local community including the potential of around 1,500 jobs during its construction phase.

Fernando Salinas, Managing Director of FRV Mexico and Central America, highlights: “Mexico is a country that offers numerous opportunities for both FRV and international investors, due to its favorable market and weather conditions for renewable energy projects. Potrero’s financial close marks a milestone as the largest bifacial plant in the world and FRV’s first fully merchant project in Mexico. By carrying out this flagship project that will lead the way for other large-scale bifacial PV plants and that is also one of the largest PV merchant projects worldwide, FRV demonstrates its leadership once again and its ability to be a spearhead in the wider renewable energy industry.”

Bancomext assures that “Potrero Solar has all the features a financial institution looks for during a transaction: an experienced, highly professional sponsor, high-quality technology, an EPC provider with a well-proven track-record and a solid financial structure. With this project, Bancomext reaffirms its leading position in the Mexican market, supporting renewable energies under the ‘spot market price’ scheme and fostering job creation in the country during the construction and operation phases.”

Fady Jameel, Deputy President and Vice Chairman of Abdul Latif Jameel, said: “At Abdul Latif Jameel Energy, we are delighted to move forward to the next phase of the Potrero project. Potrero confirms FRV’s positioning as one of the leaders in the global renewable energy sector and further reinforces our long-term commitment to Mexico’s drive for clean energy. Mexico is a strong and promising market for FRV and Abdul Latif Jameel Energy, and we look forward to seeing Potrero spearhead the development of the sector in the country and further afield.”

Acciona has created a hub in its El Romero Solar plant (Atacama, Chile) to test new photovoltaic technologies that will improve the efficiency and performance of solar energy facilities.
The hub will focus on the mechanical and energy capacity of double-sided crystalline, split-cell and thin-film cadmium telluride (CdTe) technologies, all of them in the development phase, with the intention of shaping PV energy’s evolution. The solar modules have been produced by JA Solar and First Solar, and a variety of solar trackers will be used, manufactured by STI Nordland and Soltec.

The innovation center, in which two of the three tracker zones have already been installed, will have a power generation facility with a total capacity of 492 kWp (180 kW rated) consisting of 1,280 modules in three series of trackers connected to nine inverters. These will be assisted by other equipment to measure and monitor parameters such as incident and reflected solar radiation, ambient temperature or the production temperature of each kind of module, among others.

Unlike conventional solar modules, which only have photovoltaic cells on one side, the double-sided modules have cells on both sides of the panel to capture reflected solar radiation and increase output per surface unit occupied.

In split-cell modules each cell is divided into two parts. This reduces energy losses and improves the durability of the panel.

Finally, the thin-film modules are made from semi-conductive materials as alternatives to conventional crystalline silicon –such as cadmium telluride- that reduce both manufacturing costs and their carbon footprint during their working life.

Advanced technologies

Advanced technologies in photovoltaic solar are one of the main strategic approaches that guide Acciona’s innovation activities in the field of clean energies. One of the most innovative projects to date is the hybridization of organic photovoltaic panels in a wind turbine tower to power a turbine in the Breña wind farm (Albacete, Spain).

El Romero Solar is one of the biggest photovoltaic plants owned and operated by Acciona, with a capacity of 246 MWp. Located in the Atacama Desert in Chile, an area with some of the highest levels of solar radiation in the world, it produces energy equivalent to the consumption of around 240,000 Chilean households. Part of its capacity will be used to supply Google’s data center in the country.

Africa’s first 100% solar-powered desalination plant has produced 10 ML of fresh drinking water—with help from Danfoss APP pumps and iSave energy-recovery technology.

Developed by Mascara Renewable Water and Turnkey Water Solutions, the OSMOSUN® unit at Witsand—in South Africa’s Southern Cape—is powered solely by photovoltaics (PVs) producing 73kWh/day.

Taking water from the sea, the plant provides people in the historically drought-prone region with up to 100,000 L of safe, drinkable water per day.

The seawater reverse osmosis (SWRO) conversion process uses a highly efficient Danfoss APP pump to force water through a desalination membrane under high pressure. The water’s kinetic energy then drives the iSave 21 Plus energy recovery device.

Specifically developed for SWRO applications, the Danfoss iSave 21 Plus recovers kinetic energy that would otherwise be lost and returns it to the plant. The APP pump’s simple construction also makes it compact—with very little maintenance required—ideal for remote sites. What’s more, it’s oil free, so the risk of unplanned downtime is significantly reduced and there’s zero potential for water contamination.

Mascara’s OSMOSUN® system is already proven in other parts of the world (we have a more detailed story about its PV-powered SWRO plant in Abu Dhabi). At full capacity, it can produce approximately 300,000 L/day, using 400 m2 of PV panels.

Ingeteam has supplied 2 GW of power for solar PV plants throughout the world during the first half of 2019. This means that the company’s technology will be capable of supplying renewable energy to more than 400,000 homes once commissioned. In total, the Spanish company has reached a cumulative power of 14.5 GW throughout the world, which could satisfy the energy demand of about 3 M homes. In 2019, the key markets in which the company has grown its solar business are the Middle East region, Australia, Mexico, Spain, Chile and France.

Ingeteam closed 2018 with a new record of 3.85 GW supplied, for solar PV installations worldwide. So far this year, Ingeteam has already exceeded half this figure and the company is expected to pass the barrier of 4 GW in 2019.

The Ingeteam Group is one of the world’s leading suppliers of technological solutions for PV plants, control, monitoring and automation systems as well as energy storage systems. In this regard, this year Ingeteam has been entrusted with the supply, commissioning and provision of services for the largest solar PV project in Europe, now being built in the region of Murcia, Spain. The company was awarded the contract for the Mula project, which will achieve an installed power capacity of 500 MWp, to become the largest plant in Spain and Europe.

It is estimated that, by the end of 2019, the plant could be operating through the connection point at the El Palmar substation, a strategic hub for the power transmission grid in the region of Murcia.

Energy storage

Energy storage is a key sector for Ingeteam, where the company is positioning itself for the considerable development expected in the short and medium term for systems of this type, both at a residential level and also on a large scale. In fact, Ingeteam is marketing its battery converters for both segments and, in 2018, the company supplied this equipment primarily for hybrid systems that combine PV generation with energy storage. Sales in this sector were principally made to countries such as the United States, Spain, the United Kingdom, Australia, the United Arab Emirates, India, Poland and the French overseas departments.

Global leader in the provision of Operation & Maintenance Services

Furthermore, the company has achieved a new annual record for maintained power, exceeding 15 GW of renewable power across the globe, of which 6.1 GW correspond to solar power in more than 550 PV plants. This means that, at present, Ingeteam’s operation and maintenance division is strengthening its position as a global leader in the provision of O&M services at energy generation plants.
