Using air conditioning to cool down PV modules, dry dishes
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.
‘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).
European Commission approves Italy’s incentive scheme for agrivoltaics
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.
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.
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.
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.
Vertical rooftop PV specialist switches on two more systems on green roofs in Norway
Norwegian vertical solar system specialist, Over Easy Solar, recently supplied a 102 kW bifacial commercial rooftop system, just a few months after supplying a 45 kWp system for a school rooftop. Both systems were installed on so-called green rooftops by the Norwegian project company, Solenergi Fusen.
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).
