Scientists in Russia have developed an active cooling technique that spreads water on both sides of the module and uses a cotton wick mesh to absorb and spread the water that comes on the rear side. The system is able to reduce significantly a module’s operating temperature and lead to an overall improvement of 30.3% in its output power.

SunDrive said it has created the most effective commercial-sized silicon solar cell in the world, achieving an efficiency figure of 25.54% in testing carried out by Germany’s Institute for Solar Energy Research (ISFH).

Does higher energy production outweigh an increase in costs? Clean Energy Associates tries to answer this question in a new case study.

The result is claimed to be the highest efficiency ever reached for a large-area, polymer film-based perovskite photovoltaic module. The device has an area of 703 square centimeters and was fabricated through a new coating method.

Scientists in the United States explored the use of all back contact architectures for perovskite solar cells. The group notes several advantages to this strategy, as well as challenges to overcome. Ultimately, the work outlines a route to cell efficiencies better than 20%.

Rollercoaster stocks, unpredictable interest rates and continuing Covid chaos on global exchanges have apparently convinced the developer to invest in what it deems is a safer bet.

The Latin American country may see unprecedented growth for PV systems not exceeding 5 MW in size during this decade, according to Brazil’s state-run Empresa de Pesquisa Energetica (EPE) agency. New rules now under discussion in the parliament may further boost this market segment and lead, eventually, to another 30 GW of installed solar power.

The three Chinese panel manufacturers found an agreement on the module size and the mounting hole spacing.

Brazilian researchers have proposed a new mathematical model to change parameters for wind and solar resources and different levels of energy demand. The model was originally conceived for tropical regions, but it can actually be used in any location. The new methodology models a highly complex system featuring wind turbines and PV modules, as well as solar collectors, fuel lines, gas boilers, engine-generator sets, recovery boilers, absorption and compression chillers, and grid electricity.

Maxwatt Solar has built a PV system that is purportedly India’s largest residential on-grid residential solar installation, with 540 Wp modules. It uses 68 of JA Solar 540 Wp half-cell mono PERC modules and a 27 kW Fronius inverter.
