Sharp presents 375 W rooftop PV module for gable roofs
Sharp’s new 375 W solar panels feature multi-wire technology, with a power conversion efficiency of 20.4%.
Open-source software to identify best locations for PV projects in urban areas
The proposed methodology relies on geographic information and meteorological data. Project developers can use it to evaluate the potential energy production by a photovoltaic system for either a long or short time.
Risen launches 450 W rooftop solar module with 21.7% efficiency
The panel measures 1,894 mm x 1,096 mm x 30 mm, weighs in at 22.5 kg, and has a temperature coefficient of -0.34% per C.
What are upfront and lifetime costs of heat pumps in the US?
The “all electric” movement is shining new light on heat pumps. A recent survey looks at their costs in terms of replacements for heating and air conditioning systems.
Photovoltaic sanitary water heater from Belgium
Belgian heating specialist Wanit has developed a solar water heater that purportedly reduces the cost of domestic hot water by 85%. The PV water heater solution includes a main dual tank and a solar connector that links the tank with a rooftop PV system and residential battery.
Novel mounting structure for PV systems on thermoplastic polyolefin roofs
Mibet has developed a new PV mounting structure made of stainless steel and aluminum, providing a perfect match between TPO fixing supports and trapezoidal metal rooftops. The apparatus includes a rail, two clamp kits, a support kit, the TPO roof fixing support, and a TPO cover plate.
Studer reveals 3-phase inverter-charger for off-grid, on-grid rooftop applications
Studer Innotec, a Swiss power electronics specialist, has unveiled a 16 kW inverter for off-grid and on-grid applications. It features two maximum power point tracking inputs in an 8 kW plus 8 KW configuration.
Is residential solar worth it in the US?
Many homeowners invest $15,000 to $30,000 or more in solar. How does this cost compare to the status quo of paying the utility company?
Cost comparison between lithium batteries, fuel cells, reversible solid oxide cells as storage for off-grid rooftop PV
Scientists in the United Arab Emirates have looked at how off-grid rooftop PV could be combined with batteries, fuel cells or reversible solid oxide cells for energy storage. The modeling assumed a typical commercial building in Los Angeles.
Novel way to turn semi-finished thin-film solar modules into colored BIPV panels
German scientists have developed a way to cut semi-fabricates into desired shapes and then apply a conductive oxide-metal-oxide electrode with the preferred color. They can structure the elements into modules via the backend interconnection process.
