Researchers in Kenya have analyzed the performance of an off-grid PV system located near an isotropic antenna as an emitting source.

To achieve the government’s ambitious renewable energy targets, and integrate the two growing sectors of infrastructure and construction and renewable energy, the existing policies and codes for green buildings need to be further enhanced. Most of these rules need to include specific details about energy generation. Right now, these are more to do with energy efficiency. 

Swiss manufacturer Megasol said the new product is compatible with the most common tile formats and also available in different colors. Megasol has also developed a coating that eliminates the glare effect of solar modules.

Insolight has developed a translucent monocrystalline solar panel with a nominal power of 106 W and a power conversion efficiency of 20.1%. The solar cells are covered with protective glass and optical lenses to concentrate and direct sunlight onto them at around 100 times the intensity of standard solar glass.

The handheld, cordless cleaning tool is a cost-effective and efficient alternative to automated cleaning robots that are usually limited in operation by panel inclination. 

Scientists in India developed a mathematical model to predict the output of solar cells and modules in the field. The model was developed and tested using both sun simulator and actual installed modules. The scientists state that their model can be applied to a PV installation anywhere in the world, and that by taking into account module degradation over time their forecasts can be as much as 26% more accurate than existing energy yield models.

Trina Solar has found that its Vertex modules, based on the 210mm wafer, achieve an energy yield up to 1.6% higher than rival products based on the smaller 182mm wafer format. The company conducted outdoor testing at two separate sites with varying climates, finding that products based on the larger format have a particular advantage in low-irradiance environments.

Australian startup Gelion is seeking to commercialize a non-flow zinc-bromide battery based on a stable gel replacing a flowing electrolyte. According to the manufacturer, the device is safe, robust and recyclable.

Scientists in India conducted a techno-economic analysis for a 100 MW production line for carbon-electrode perovskite solar modules, located in Himachal Pradesh, India. The analysis concludes that, even at the smaller scale, this emerging technology could achieve cost levels comparable with today’s silicon solar products.

The Solliance consortium has built a solar cell in a four-terminal tandem configuration that combines a 17.8%-efficient highly near-infrared transparent perovskite cell with a prototype of an 11.4%-efficient c-Si interdigitated back contact silicon heterojunction cell developed by Panasonic.
