The GIANTS is developing lighter weight, solar-powered, cost-conscious, three and four-wheel prototype vehicles for passengers and cargo.

Lightweight mobility with vehicle-integrated photovoltaics

The Green Intelligent Affordable Nano Transport Solutions (GIANTS) is a €12 million, 42-month project with 23 partners from industry and research institutes. The group is designing a platform to enable three types of lighter-weight, cost-conscious, solar-powered electric vehicle prototypes for passengers and cargo.

The platform includes battery technology, powertrains and solar PV components that will be standardized.

Small fleets of the GIANTS’ LEV prototypes will be demonstrated in the European cities of Stockholm and Bruges, plus demonstration sites in Kisumu, Kenya, Delhi, India, and Manila, Philippines.

Maldives has issued an invitation to tender for the installation of 10 MWp grid-connected floating solar PV systems in Addu city.

Maldives tenders 10 MW of floating photovoltaics (PV) in Addu city

The Government of the Republic of Maldives, with funding from the World Bank, has issued an invitation to tender for the installation of 10 MWp grid-connected floating solar photovoltaic systems in Addu city. This project is part of the Accelerating Renewable Energy Integration and Sustainable Energy (ARISE) initiative, which aims to improve the country’s renewable energy capabilities.

The Ministry of Finance, on behalf of the Ministry of Climate Change, Environment and Energy, is seeking bids for two specific lots under the Design, Build, Financing, Own, Operate and Transfer (DBFOOT) modality. Lot 1 involves the installation of 2 MWp grid-connected floating solar PV systems at Maradhoo Port and Hulhumeedhoo Central Port. Lot 2 covers the installation of 8 MWp grid-connected floating solar PV systems in the Hithadhoo port area.

Researchers in Iran found that only 4% of the greenhouse’s roof must be covered with PV modules to meet lighting and pumping water demand.

Photovoltaics for hydroponic greenhouses

A research group from Iran’s University of Tehran has conducted a feasibility study for the use of PV systems in commercial hydroponic greenhouses across the country.

Their work consisted of calculating the total energy input of a strawberry greenhouse in a case study that currently runs on natural gas and electricity, and then simulating the area required by a PV system to completely replace grid electricity.

“This study aims to assess the energy and environmental aspects, as well as the practicality of employing photovoltaic cells to meet the energy requirements of a commercial hydroponic greenhouse in Alborz province,” said the scientists. “Data was gathered from a 3,000 m2 strawberry hydroponic greenhouse through on-site visits, surveys, and measurements.”

Now, in Scotland, the development of a hexagonal solar panel that could work even at night has just been announced.

Hexagonal solar panel that works at night: the mirror that will illuminate the Earth from the outside

,

As you might expect, one of the biggest obstacles for photovoltaics is the nights of our planet. The panels maintain their ability to absorb light at all times, however, during long hours, they must remain inoperative. Now, in Scotland, the development of a hexagonal solar panel that could work even at night has just been announced.

A solar panel that still works at night? Yes, but it’s not the one you know from Tesla

While sunlight is an abundant and renewable resource and is even the oldest known source of energy, it is also true that obtaining electricity from the sun has proven to be a more complicated task than one might expect. Among other factors such as climate, the greatest difficulty in achieving a constant flow of energy to the solar batteries is the rotation of the earth.

Scientists in China have developed a PV-driven direct-drive refrigeration system for electronic device cooling.

Photovoltaics for vapor compression refrigeration

,

Researchers at the Hebei University of Technology in China have designed a solar photovoltaic direct-drive refrigeration system with low energy consumption for high heat-flux electronic device cooling.

“The proposed system integrates photovoltaic power generation with direct-cooling and vapor compression refrigeration (VCR),” the research’s lead author, Xiaohui Yu, told pv magazine. “The combination of micro-evaporator and direct cooling method can achieve good heat exchange efficiency.”

The system consists of two subsystems: a PV unit including a battery and an maximum power point tracking (MPPT) controller; and a VCR unit comprising a DC rotary compressor, a fin air-cooled condenser, an electronic expansion valve, an embedded direct cooling evaporator, and a dry-filler.

Transparent solar cells will transform the look of infrastructure by enabling many more surfaces to become solar panels.

A shade closer to more efficient organic photovoltaics

,

Transparent solar cells will transform the look of infrastructure by enabling many more surfaces to become solar panels. Now, materials called non-fullerene acceptors that can intrinsically generate charges when exposed to sunlight could make semitransparent organic photovoltaics easier to produce, a KAUST-led international team shows.

Semitransparent photovoltaics are able to convert sunlight into electricity without blocking visible light. This makes them attractive for building integrated applications, such as windows, facades and greenhouses.

Elevated metro stations may highly benefit from rooftop solar power generation combined w/ battery storage, new research from China suggests.

Photovoltaics for elevated metro stations

Researchers from the Xi’an Jiaotong University in China have investigated how rooftop solar and battery storage may help cover energy demand in elevated metro stations and found this combination may achieve a self-sufficiency rate of up to 54% and a payback time of 10.2 years.

“Our work is the first study focusing on the PV potential of elevated subway stations based on real energy loads,” the research’s lead author, Haobo Yang, told pv magazine. “Our findings are based on measured hourly load demands and include the impact of battery energy storage on PV system performance.”

In the study “Technoeconomic analysis of rooftop PV system in elevated metro station for cost-effective operation and clean electrification,” published in Renewable Energy, Yang and his colleagues said their work is intended to provide a benchmark for cost-effective operation and clean electrification in urban metro networks.

Metal trees with a seven-meter canopy of solar panels that generate electricity may soon be coming to car parks and shopping malls in the UK.

Solar trees could soon be charging your car

Metal trees with a seven-meter canopy of solar panels that generate electricity may soon be coming to car parks and shopping malls in the UK.

The structures, which will capture the sun’s energy through nano photovoltaic “leaves” and could store it in a battery placed within the tree’s trunk, were designed by British startup SolarBotanic Trees as a power source for charging electric vehicles (EV). The company recently completed a half-scale prototype of the device and is now looking to build and test a full-size version, before beginning commercial production at the end of the year.

In the UK, EV charging infrastructure is rapidly growing, with more than 40,000 public charging points installed by the end of April 2023, up 37% from the previous year, according to ZapMap, an EV mapping service. But this still does not keep up with demand, with the UK’s Climate Change Committee estimating that 325,000 charging points will be needed by 2032 to support the growing electric fleet.
