Emil Otto has created a range of cleaning agents for solar panels. “Photovoltaic modules must be cleaned regularly to ensure maximum performance,” according to the company. “However care must be taken when cleaning as the use of chemical cleaning agents carries a considerable risk of damage. Aggressive chemicals or abrasive cleaning agents can scratch or corrode the sensitive surfaces of ...
Intepro Systems is stocking a 50kW regenerative ac-dc electronic load and grid simulator from Cinergia. Called ‘GE&EL+ vAC/DC SiC’, Intepro describes it as: “The whole Cinergia catalogue in a single unit. [It] is both an ac and dc grid emulator, and can also works as a load [and] is ideal for testing solar panels, wind turbines, hardware-in-the-loop power, smart grids, ...
Fluke is aiming at mid-sized solar power installations with PVA-1500HE2, an analyser and I-V curve tracer rated at 1.5kVdc and 30A. “Similar products can often struggle to obtain accurate readings due to high capacitance levels and are incapable of recording data continuously without overheating,” claimed the company. “Having to disconnect an I-V curve tracer until it cools down is disruptive. ...
BASF Schwarzheide has installed a 1MW 5.8MWh sodium-sulphur battery to increase the amount of energy it can use from the solar park at its manufacturing site in Lusatia Germany, where it produces electric vehicle battery materials. “The stationary energy storage system is another step towards increased sustainability in battery production for electric vehicles,” said company v-p of battery metals Daniel ...
A single company is to build 1.1GWpeak of solar capacity in Germany over the next three years. Securesun, has over 50 solar part projects scheduled to be competed before the end of 2026, averaging 20MWpeak, with the largest at 150MWpeak. Last year, roof-top and park installations combined, Germany built 7.2GWpeak* of solar capacity. “We are very pleased that we can ...
Omron is aiming to replace conventional contactors with its most powerful ac PCB relay yet: G9KA-1A-E, which handles up to 1kVac and carries up to 300A. Sitting on a 51 x 51mm footprint, the relay is 54.5mm tall and weighs ~235g. The contacts are cadmium-free silver alloy and offer 200μΩ on-resistance (at 200A). Maximum timing is 30ms make and 10ms ...
Fabless power transistor company Cambridge GaN Devices (CGD) is to sign a deal with Neways Electronics of Eindhoven to develop solar power inverters. The collaboration has sprung from the European-funded GaNext project, on which both companies worked. “At Electronica, both on the Neways booth and at CGD’s booth, visitors will be able to see a demo of a 3kW photovoltaic ...
STMicroelectronics will procure 50% of the energy for its Bouskoura site in Morocco from renewable sources by 2022, compared to 1% in 2020. The electricity of 12 wind turbines in North Morocco will be fed into Morocco’s national power grid and then purchased by ST. These are on a 10ha wind farm near the coast at Oualidia, built by InnoVent and planned ...
Vishay has created a series of high ripple current aluminium electrolytic capacitors for solar power converters. “Designed for solar applications, Solar 193 PUR-SI power capacitors offer rated voltage of 500V and useful life of 6,000 hours at a maximum operating temperature of 105°C,” according to New Yorker Electronics, which is stocking the parts. Rated ripple current is 2.52A at 450 ...
LG Electronics’ latest commercial solar panel can reach an efficiency of 21.4%. It is the LG370N1C-N5, styled a ‘premium’ product by the company – an n-type monocrystalline panel producing 370W max from its 1.7 x 1m surface (irradiance 1,000W/m2, 25°C, 1.5AM). Open-circuit under the same illumination it delivers 41.8V, and short-circuit the figure is 10.92A. Maximum power is achieved at 35.8V ...
