‘Cool roofs’ increase power yield in bifacial rooftop PV systems
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.
New MPPT approach for multi-string PV systems under partial shading
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).
SAJ releases new battery inverter series for residential applications
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 to use flexible appliances for renewable energy integration
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.
Cyprus embraces residential solar, awaits competition
Cyprus has announced a new scheme to increase residential solar deployment and help about 6,000 households to lower their electricity bills. Constant delays in the opening of the national retail electricity market to competition, meanwhile, are costing households millions.
Euro’s electricity prices recovered by falling wind generation
Electricity market prices recovered in the second week of November due to falling wind production. MIBEL recorded the lowest weekly average price for the third consecutive week.
Collectively owned PV systems improve energy community performance
Researchers have looked into the impact of potential regulated charge exemptions on two types of energy communities in 39 European countries. They have found that communities with collectively owned PV systems achieve greater savings.
Florida community teams up with Block Energy on $4.2 million solar microgrid
A Florida new home subdivision has reached a $4.2 million agreement with Tampa-based Block Energy to install 77 solar arrays in a community microgrid.
Residential photovoltaic panels with high partial shading tolerance, high voltage
Scientists from South Korea have designed new photovoltaic modules with both rectangular and triangular shapes and solar cells connected in parallel, which they said have higher partial-shading tolerance compared with cells connected in strings. The panels are reportedly less sensitive to partial-shading geometries than shingled modules.
India’s solar installations surpass 72 GW
India’s cumulative solar installations hit 72.02 GW as of Oct. 31, 2023. Grid-connected solar rooftops account for 15.38% of all installed capacity, according to the Ministry of New and Renewable Energy (MNRE).
