Enphase’s new IQ8-3P solar microinverter offers peak power output of up to 480 W.
Tongwei has developed the G12 TOPcon solar module series, with efficiency ratings up to 23.1% and a temperature coefficient of -0.30% per degree Celsius.
Prof. Ricardo Rüther, the coordinator of the Strategic Solar Energy Research Group at the Federal University of Santa Catarina (UFSC), installed a solar energy system at the university 26 years ago. It currently operates at about 80% of its nominal power.
The threat of catastrophic climate change, as well as increasingly obvious economic benefits, make it advisable, indeed essential, to convert our entire energy system to a sustainable system, based on renewable energy (RE) as soon as possible. The two main pillars of our future RE-based energy system will be power generation from PV and wind. In Germany alone, according to detailed studies by Fraunhofer-Institut für Solare Energiesysteme ISE, we will need at least about 300 GW of PV and an equally large amount of wind power.
An international research team has investigated how air conditioning may be used to reduce the operating temperature of PV panels. The researchers not only found that the proposed approach is technically viable, but they also tested the use of excess heat from the panels for drying dishes.
A Spanish-Algerian reserch group has tested how “cool roofs” could help increase power yield in rootop bifacial PV systems. Cool roofs are based on coating materials with high reflectance properties.
Egyptian researchers have developed a multi-string PV system with a converter control strategy, achieving 99.81% efficiency with a direct duty cycle for maximum power point tracking (MPPT).
The European Commission has approved Italy’s €1.7 billion ($1.84 billion) incentive scheme for agrivoltaics to deploy 1.04 GW of installed solar. The nation will offer investment grants of up to 40%, along with 20-year tariffs.
China’s Guangzhou Sanjing Electric (SAJ) has developed two new single-phase and three-phase all-in-one battery inverters with efficiencies of 97.8% and 98.0%, respectively. They use artificial intelligence to support energy management.
California plans to shift 3 GW of load from dirtier, more expensive times of day to cleaner, less expensive times by setting flexible demand standards for many types of electric appliances. Global interest in California’s work is high, according to a state agency commissioner.
