Technology and R&D

UK researchers have analyzed the multiple effects of PID on 28 modules at an outdoor testing field. The novel approach considered all multiple PID effects through a comprehensive analysis, which included power losses, hotspots, mm-level defects, and the performance ratio.

The 8 kW photovoltaic shade was deployed on the outdoor rest area of a commercial building located in the northern part of Madrid. It was built with conventional solar modules provided by JA Solar and a structure made with light galvanized steel profiles for plasterboard partitions.

With Ford Intelligent Backup Power and the Home Integration System, F-150 Lightning will automatically kick in to power the home if the grid goes down, while also giving customers the freedom to charge their truck or power their home using their residential solar installation.

Conceived by scientists in China, the device combines an integrated carbon-based perovskite solar cell module with a rechargeable aqueous zinc metal cell. The proposed system achieved an overall efficiency of 6.4%, and a steady operation for more than 200 cycles with little performance degradation.

The US National Renewable Energy Laboratory has released a free, web-based platform for automatic residential solar permit approvals.

The manufacturer said the 40/40 warranty is the longest and most comprehensive combined warranty offered in the photovoltaic industry to date. The product line is sold in most countries outside the United States and Canada under the SunPower Maxeon brand.

Canadian companies Invinity and Elemental Energy are planning to couple a 21 MW solar plant under development in Alberta with 8.4 MWh of vanadium redox flow battery storage capacity.

Developed by French start-up Ecosun, the trailer is equipped with 15 solar panels with output of 360 W and batteries with a storage capacity of 23 kWh. It can be used for construction sites, military camps and water pumping systems.

Churches use energy mostly during the day, which makes them ideal buildings to deploy solar panels. Scientists in the United Kingdom have assessed the financial viability of a rooftop PV project for Bath Abbey and found that it could become profitable after 13 years.

Chinese scientists used perovskitoids as 1D and 0D capping layer materials for the cell’s perovskite layer. These materials enabled an effective and all-around passivation of the perovskite surfaces and grain boundaries, which prevents undesired Shockley-Read-Hall recombination and material degradation. The device achieved a power conversion efficiency of 24.18%, an open-circuit voltage of 1.151 V, a short-circuit current of 25.96 mA/cm2, and fill factor of 80.91%.
