Sensorless approach for PV panel temperature monitoring
Researchers in United Arab Emirates have developed a novel model that relies on either the open-circuit voltage or the maximum power point voltage to estimate PV module operating temperature without using sensors.
US-based mPower Technology opens automated solar module line for space
mPower Technology Inc. has switched on an automated production line for its silicon solar panels designed for space missions. The site currently has an annual capacity of 1 MW, set to double by the middle of 2026.
Optimizing PV system tilt angle, MPPT using fuzzy logic controller
Researchers in the Middle East have developed a fuzzy logic controller that simultaneously optimizes the tilt angle of PV systems and performs maximum power point tracking (MPPT). Year-long simulations indicate that the proposed approach increases power generation by approximately 20%.
U.S. scientists build graphene-based solar cells than can charge supercapacitors
The solar cells combine multilayer graphene with silicon wafers, harvesting both solar and kinetic energy for continuous operation. Tests show the cells can autonomously power supercapacitors embedded in a temperature sensor.
US startup launches DC-powered solar water heater
California-based Apparent Inc. has unveiled a new water heater that can reportedly offset 100% of a home’s water heating cost. The system uses low-voltage DC electricity generated by conventional solar panels and a cloud based, machine learning platform that manages energy in real-time.
