Single-axis tracker with two rows and smart algorithms
Deploying trackers can offer a higher yield, as they are tracking the sun, to bring the modules into a perfect azimuth position throughout the day. Like modules, these devices are constantly being developed to make them more efficient, cheaper, and easier to install. In this pv magazine Webinar, we will hear what Soltec has developed to attain these goals in their latest product update.
Floating photovoltaics may significantly reduce water evaporation at Aswan dam
The Aswan High Dam Reservoir is one of the world’s largest water reservoir and suffers from high water evaporation rates due to the region’s very hot and dry climate. Floating PV installations may be a remedy, while also offering a good match for hydropower generation.
The Hydrogen Stream: 1.2 TW of electrolyzers globally in development
Aurora Energy Research says it has recorded a sharp increase in green hydrogen projects, with 90% of them in early phases of development, while E.ON says that Germany’s hydrogen ramp-up is stuck due to an investment backlog.
US to upgrade power transmission infrastructure
As the US Inflation Reduction Act (IRA) ramps up clean energy efforts across the United States, the government has outlined a plan to expand transmission lines to accommodate more power.
Improving solar panel recyclability with lasers
The National Renewable Energy Laboratory developed a proof of concept for a method to remove polymers from solar panel manufacturing to enable more efficient recycling.
First silicon solar cell celebrates 70th birthday
On April 25, 1954, US researchers presented the first prototype of a usable solar module. The efficiency at that time was around 6%. A lot has happened since then.
TotalEnergies builds 12 MW solar carport at New York’s JFK Airport
French energy giant TotalEnergies has started building an onsite solar-plus-storage system at John F. Kennedy International Airport in New York City. It will provide energy to the Port Authority of New York and New Jersey and Con Edison, as well as community solar for area residents.
SunPower to close business units, cut about 26% of workforce
The US-based company announced plans to wind down its residential solar installation locations and close its direct sales unit.
Solar-assisted heat pumps vs. air-source heat pumps
A group of researchers in Iran has analyzed the coefficient of performance and the energy consumption of a solar-assisted heat pumps and an air-source heat pumps and has found that three factors are crucial to determine their annual performance – irradiance changes, ambient temperature, and wind speed.
NREL updates interactive chart of solar cell efficiency
The US National Renewable Energy Laboratory (NREL) has updated its research cell efficiency chart for a range of PV technologies.
