Subsea pumped hydro for utility scale storage at deepwater
Researchers in Norway have investigated the technical potential of implementing subsea pumped hydro storage at water depth not exceeding 2,000 m. They also identified potential locations for these storage systems based on energy density.
The impact of climate-based PV panel degradation rates on inverters
New research from Belgium shows the importance of assessing inverter reliability by including climate-based PV panel degradation rates. The scientists found that, especially in hot and arid climates, PV inverters should be designed with parameters above the standard value.
How to combine residential heat pumps with PV, battery storage
New research from Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has shown that combining rooftop PV systems with battery storage and heat pumps can improve heat pump efficiency while reducing reliance on grid electricity.
Reducing PV module temperatures with graphene
New research from Malaysia has shown the limitations and potential of all solar module cooling techniques based on graphene. The scientists said that high costs and graphene treatments are the main challenges to overcome.
Sharp unveils 580 W TOPCon solar panel with 22.45% efficiency
Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.30% per C and a bifaciality factor of over 80%.
AEG launches 23.3%-efficient ABC solar panel with 40-year warranty
AEG is currently offering three versions of its new ABC solar panels for rooftop applications, with power outputs of 445 W to 455 W and efficiency ratings ranging from 22.8% to 23.3%. They feature half-cut ABC cells with n-type technology.
PV commissioning times up by 6 months over past 20 years, claim scientists
Scientists in Switzerland used project-level data from BloombergNEF to analyze completion times of renewable energy projects across 48 countries. They have found that average commissioning times have increased over the past two decades for all clean energy technologies.
PV may help CSP reduce its LCOE by 18% in Saudi Arabia
Researchers have found that the current levelized cost of energy (LCOE) for concentrated solar power (CPS) plant in Saudi Arabia could be as low as $0.137/kWh. However, combining the tech with PV would significantly enhance the cost competitiveness of CSP.
Trina Solar presents bifacial dual-glass TOPCon solar modules for rooftop PV
The Chinese manufacturer said its new TSM-NEG9RC.27 and TSM-NEG18R.28 combine n-type technology with 210mm rectangular silicon wafer (210R) cell technology. Their temperature coefficient is -0.29% per C and their efficiency can reach up to 22.3% and 22.7%, respectively.
Hybrid optimization MPPT tech for PV systems under partial shading
Researches in India have used the adaptive network-based fuzzy inference system (ANFIS) and the grey wolf optimization (GWO) algorithm to develop an MPPT technique that reportedly increases the PV source voltage of an array under partial shading conditions.
