PV system sizing for 100% self-consumption
A group of researchers has proposed a new method for the sizing of PV systems that do not rely on an anti-dump system and operate without the possibility of injecting power into the grid. The novel approach requires an estimate of the annual hourly profile and the minimum power demanded, as well as the use of an irradiance meter and an electrical network analyzer.
Wattstone launches new concrete bases for rooftop PV
The German company said its new products are suitable for PV systems with tilt angles ranging from 0 to 15.6 degrees.
Quantifiying benefits of vehicle-integrated photovoltaics
Austrian researchers developed a model to quantify the benefits of vehicle integrated photovoltaic (VIPV) on the energy needs of three different sizes of electric vehicle in the city of Graz, Austria, particularly the effect on battery energy and vehicle mileage.
Storing solar power through aluminum-rock composite
UK-based Caldera has developed a new heat storage technology that can reportedly convert on-site generated solar power into on-demand heat, thus replacing conventional gas boilers. The system uses a composite of recycled aluminum and volcanic rocks to store heat at up to 500 C and produce steam.
Lightweight self-attaching PV system for zinc roofing
Créawatt unveiled this week a new version of its ultra-light Luxsiol photovoltaic system for zinc roofs. It weighs only 3.25 kg/m2 enabling all types of flat roofs made of bitumen, PVC, ethylene propylene diene monomer rubber, or T333/T250 steel sheet.
Silver price on the rise
The price of silver has increased over 30% since the beginning of the year, with a particularly strong increase being registered in the last few months.
EWEC opens 1.5 GW solar tender in Abu Dhabi
Through the procurement exercise, the Emirates Water and Electricity Co. (EWEC ) is planning to build a giant solar farm in the Al Dhafra Region.
SEG Solar begins work on 5 GW solar cell factory in Indonesia
SEG Solar (SEG), a Texas-based module manufacturer, has started deploying n-type cell production lines in Indonesia’s Kawasan Industri Terpadu Batang industrial park, 390 km east of Jakarta.
Why $0.25 per kWh electricity makes off-grid solar-plus-storage a smart investment in U.S.
Once electricity prices hit $0.25/kWh, disconnecting from the grid with residential solar-plus-storage starts to become financially viable, with sunny places making strong financial arguments. With recent drops in battery prices, the case for leaving the grid has grown even stronger.
California’s Governor rules that schools and farms cannot use their own solar energy production
Gavin Newson rejected a bill that would restore a level playing field for schools, farms, and multi-family homes to go solar
