Chinese panel manufacturer DAH Solar has developed a rooftop photovoltaic module with a frameless front and an improved drainage function. The battery has a nominal power of 5.5 kWh and can be installed in outdoor environments.
Chinese module manufacturer DAH Solar has developed a photovoltaic panel with a frameless front that it claims allows dust to be washed away by rain.
“The frameless design of the front part can improve the drainage function of the PV module, so that the rain washes away the dust and reduces dust sedimentation,” a company spokesperson told pv magazine . “This feature can reduce the frequency of cleaning operations and maintenance activities and also helps prevent hot spots.”
The Full Screen panel is available in five versions with a power ranging from 450 W to 470 W and an efficiency ranging between 20.85% and 21.78%. The open circuit voltage is between 62.0 V and 62.8 V and the short circuit current is between 9.19 A and 9.43 A, with the maximum system voltage being 1,500 V.
The new product measures 1,903mm x 1,134mm x 30mm and weighs 23.5kg. It is built with 3.2mm anti-reflective glass and IP68 casing. It has a temperature coefficient of -0.35% per degree Celsius and its operating temperature ranges from -40 C to 85 C.
The module has a 25-year linear power warranty and a 12-year product warranty. The degradation in the first year is supposed to be 2% and the final power of 25 years is guaranteed to be no less than 84.80% of the nominal output power.
According to the manufacturer, the panels have passed the pressure tests carried out by the German certification body TÜV Nord and have obtained the outdoor performance of the TÜV Lab Test. “Our product can guarantee an increase in power generation of up to 11.5%, according to a report published by the TÜV Lab Test itself,” the spokesperson stated.
DAH Solar is headquartered in Hefei city, Anhui province, and currently has a 2GW solar panel factory.
8.7 kWh residential battery
Japanese car and battery manufacturer Toyota Motor Corporation has launched a new residential storage system based on its patented vehicle battery technology.
“The O-Uchi Kyuden system uses battery technology from electrified vehicles, such as Toyota Battery Control, to provide a nominal capacity of 8.7 kWh and a nominal power of 5.5 kWh,” the company said in a statement. release. "This ensures safety and provides a supply of electricity to the entire house not only in normal situations, but even during power outages caused by natural disasters."
The battery has a size of 1,142 mm x 341 mm x 432 mm and a weight of 142 kg. It can be installed in outdoor environments and with operating temperatures ranging from -20 C to 45 C. It is equipped with a hybrid power conditioner, a DC to DC converter and a vehicle power adapter with a maximum power of 1.1 kWh.
Toyota explained that the system supports power delivery from hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), battery electric vehicles (BEVs) and fuel cell electric vehicles (FCEVs) at 100V. The technology uses “many years of development of electrified vehicles, as well as on-board parts”, highlighted the company. "It provides electricity to homes for both normal use and emergencies, supporting a stress-free lifestyle."
The company has not disclosed further technical details about the battery. |
