Dunext introduces outdoor energy storage cabinet
The Chinese company said its new product is intended for commercial and industrial use. It uses 233 kWh LiFePO4 batteries.
China’s year-to-date irradiance up 30% as aerosols drop
In another weekly update for pv magazine, Solcast, a DNV company, reports that a significant reduction in airborne pollutants has contributed to year-to-date irradiance in some parts of China being up to 30% higher than the long-term average. South Korea has benefited from a similar pattern, recording a 10% increase in irradiance from January to April relative to its long-term average.
Solar cell prices decline, production regions continue to diversify
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Aiko unveils back-contact solar module with ‘fully intelligent integration’
Chinese solar cell and module maker Aiko presented its new intelligent solar module series, Navigator, at this year’s Intersolar. Based on the company’s N-type, all-back-contact (ABC) technology, Navigator promises a 3% to 5% boost in annual energy yield and lower operating costs.
