Bluetti introduces new modular residential battery system
Bluetti, a US solar and storage specialist, has developed a modular 7,600 W lithium iron phosphate battery system for residential settings, with 9.9 kWh to 19.8 kWh of flexible energy storage capacity.
New design parameters for photovoltaic-thermal air collectors
A UK-based research team has developed a new design technique for photovoltaic-thermal air collectors. The new parameters reportedly enable devices with lower PV module temperatures and higher efficiencies.
ClearVue to add 82 kW of solar glass to greenhouse in California
ClearVue plans to install clear solar glass on a System USA greenhouse in California, adding 82 kW of power.
HPS Home Power Solutions unveils hydrogen residential storage system
Germany’s HPS Home Power Solutions says its new 15 kW system uses surplus power from PV installations to produce hydrogen via electrolysis.
Quiet shift from central to string inverters in utility-scale solar
Central inverters still dominate the US utility-solar market but string inverters are beginning to get more traction in projects above 10 MW in size.
New attempt to build solar cells based on gallium-arsenide-nitrogen-bismuth
A Finnish-German research group has developed a 6 × 6 mm low bandgap GaAsNBi solar cell with an active area of 0.25 cm2. The device has an energy bandgap of 0.86 eV and is reportedly suitable for applications in multi-junction solar cells.
German startup deploys mobile dual-axis solar tracker in South Africa
SunOyster Energy has installed its PVmover system to supply power for a lodge in South Africa’s Sanbona Wildlife Reserve. It includes nine PV modules with a combined capacity of 3.8 kW.
New research suggests renewables may not necessarily foster democracy, peace
Researchers in Germany have found that there is “no evidence” to support the notion that renewable energy generation fosters peace through prosperity. The trio of academics came to this conclusion after empirically testing the assumption that distributed renewable energies may reduce international conflicts and promote democratic values.
PV equipment sales are up with high share of exports, says VDMA
German engineering association the VDMA reports strong PV equipment exports in the second quarter, representing 92.5% of sales. Overall, PV equipment sales were up by 50% compared to the first quarter of the year and up slightly compared to the same period last year, but incoming orders for PV equipment were down by 14%.
Novel tool for PV system sizing allows users to assess tradeoffs between reliability and costs
Developed by scientists in Egypt, trhe Green Energy Solutions software allows users to assess the tradeoffs between the PV system reliability and its costs. Compared to PVsyst, it has an error margin of up to 9%.
