New research confirms rooftop PV affects urban temperatures, cooling demand
Using Lyon as a case study, an international research team has simulated the effects of rooftop photovoltaic (PV) coverage in an urban area at three levels: 25%, 60%, and 100%. The results have shown that solar panels can raise daytime temperatures by up to 0.72 °C, while cooling nighttime temperatures by up to 0.42 °C. In addition, daytime air conditioning demand has decreased by about 5%.
Building-integrated concentrating photovoltaics for vertical applications
An Indian-British research team has developed a building-integrated linear concentrating PV facade by sandwiching an asymmetric compound parabolic concentrator, PERC cells, and encapsulation layers between two sheets of glass. The system was tested under both indoor and outdoor conditions and its payback period was found to be of up to 11 years.

Carousel-shaped measurement platform for Arctic PV
Scientists in Finland have created a special platform to assess the performance of PV modules operating under Arctic conditions. Specifically, it provides data for efficient system design and performance modelling validation, with azimuth and tilt angle being key parameters.
Using Asterisk Sudoku for PV system reconfiguration under shading conditions
Researchers in Qatar have used an algorithm relying on a variant of the popular logic-based puzzle to determine the optimal way to eliminate cluster shading. They have tested the new approach under fixed and moving shadows.

New model to optimize desert PV plant cleaning schedule
Scientists have used a CPLEX-based MIP model and tested it on a section of the 10 MW Masdar City Solar Photovoltaic Plant. In their simulation, they assume the use of two robotic cleaners to operate over a 90-day horizon. Total cleaning costs were estimated at $7,987.
