When it comes to hybrid microgrids, writes Fabian Baretzky, senior business development and sales manager for Dhybrid Power Systems, the incorporation of various sources of energy and complex requirements for long-term stability of the energy supply require expertise and an effective energy management system.
After China’s National Day holiday, demand started picking up at a slow pace, but the anticipated installation rush did not occur as expected, due to land and financing issues, as well as the return of winter. These factors will also delay the timing of more than 6 GW of capacity to the first half of next year. PV InfoLink has thus downwardly revised its estimates for installed capacity in the fourth quarter to 11.3 GW in China and 30 GW globally, bringing this year’s global demand forecast to below 120 GW.
The EU is solarizing its digital economy at a fast pace. The factors behind this paradigm shift in energy – when renewable energy is projected comprise 90% of the electricity mix in Europe by 2040 – include technical, economic, environmental.
It was a record year for global shipments of single-axis solar photovoltaic (PV) trackers in 2018, as they increased by more than 40%, surpassing 20 GW globally for the first time, writes IHS Markit senior analyst Camron Barati. While the United States continued to be the largest individual market for single-axis trackers last year, shipments also increased in Mexico, Australia, Egypt, Spain, and other large utility-scale markets.

The Malaysia Automotive, Robotics and IoT Institute is planning a huge solar power project which will integrate agriculture and livestock farming in the Sabah region. The research institute claims to have already secured $50 million for the project’s first, 200 MW phase. The 25,000ha required for the projects will host up to 150,000 cattle as well as cultivation of forage crops such as kenaf, corn, wheat and hay.
Liten, a research institute of the French Alternative Energies and Atomic Energy Commission, is developing a method of assessing losses at every stage from the reception of solar rays to the injection of electricity into the grid, to ‘make it possible to optimize the maintenance of the power plants to guarantee their performance’.
The Danish Energy Agency allocated 252 MW of clean energy generation capacity, of which 83 MW was solar and 93 MW solar-wind hybrid facilities which included 34.1 MW of PV capacity. The average price premium to be paid on top of wholesale electricity rates to the successful bidders has fallen 30% in a year, prompting the authorities to muse they may be allocating too much public money to support such projects.
The 2.5 MW array will operate under a payment system which guarantees grid operators will not be left out of pocket.
With the absorption of ‘hot’ charges, which lose their energy faster than it can be absorbed by any convention technology, solar cells could become massively more efficient. An international group of scientists has developed a method to examine the bond between a perovskite and charge extraction layer, and determine the most suitable materials for hot charge extraction in a solar cell.
Manufacturers and research institutes from across Europe have announced plans to collaborate on creating improved processes for CIGS module production. Optimistically named SUCCESS, the project targets production line efficiencies of better than 20% for 30x30cm modules.
The combination of pumped hydro with other storage technologies can increase renewables penetration, improve operational safety and reduce maintenance costs at large-scale hydropower plants, according to new research. The study also focuses on techniques to determine the optimal size of renewables-based pumped hydro storage systems. Costs for hybrid solar-pumped hydro projects currently range from $0.098/kWh to $1.36/kWh.
According to new research, metal chalcogenide perovskites can be used as a thermoelectric material than can convert thermal energy from the sun to usable electric power. These materials, which can also be used to develop perovskite PV cells, are known for their high thermal and aqueous stability, along with their nontoxic elemental composition.
Tasmania’s ambitions of becoming the “battery of Australia” improved following early reports on the proposed Marinus Link, a second interconnector between the states of Tasmania and Victoria, which show that the project’s economic advantages far outweigh expected costs.
This quarter, pv magazine‘s UP Initiative focuses on lead – a toxic heavy metal that’s present in many PV technologies, and one that’s often mentioned in connection with hazardous substances across the green energy supply chain. We take a closer look at the issue and ask what it would mean for manufacturers to replace lead in their modules with more environmentally friendly materials.
