Scientists in Spain have simulated the combination of power-to-heat-to-power storage systems with lithium-ion batteries to supply energy needs and heat pump production of an electrified dwelling. PV self-consumption was found to increase by up to 20% and levelized cost of energy decrease by 7%.

Solyco is developing a new low-temperature technology for the interconnection of solar cells. It consists of a round copper core with a diameter of 280 μm that is covered by a very thin layer of silver for corrosion protection and then surrounded by a 40 μm coating of an electrically conductive thermoplastic.

In a new weekly update for pv magazine, OPIS, a Dow Jones company, FOB China TOPCon below 450 W modules for spot loading were stable at $0.093/W, with price indications between $0.087-0.100/W. Furthermore, it reveals that current price increases are not being uniformly adopted across all Chinese manufacturers, with significant price differences—often several euro cents— being observed between the Top 5 and Top 10 manufacturers.

Scientists in Spain have proposed a novel way to calculate the structure shading factor and mismatch losses for the rear side of bifacial PV modules using one-axis trackers. They tested the new methodology in a real PV system and found it is able to establish a linear fit based on distance from the torque tube.

The system consists of a reversible compressor connected to a storage unit that can be installed indoors or outdoors. The compressor must be connected to the solar panels, with the whole system being controlled by an application that optimizes self-consumption.

Colombia’s energy regulator has approved new regulations allowing the creation of energy communities, aiming to add at least 1 GW of renewable capacity to the national grid.

This expansion comes at a critical time for the U.S. solar industry with much uncertainty around supply chains and pressure to increase domestic output.

ContourGlobal’s site features six-hour storage capacity alongside 221 MW of solar generation capacity. It is located in northern Chile and is part of a portfolio acquired from Spain’s Grenergy last year.

The Chinese manufacturer said its new heat pump system can continuously and stably provide hot water up to 75 C. At a temperature between 35 C and 55 C, the new product can reportedly achieve a seasonal coefficient of performance (SCOP) of 4.6 to 5.23, with COP values ranging from 3.86 to 5.63.

Scientists at the Korea Institute of Energy Research claim to have achieved the highest efficiency ever reported for a perovskite-CIGS tandem solar cell with flexible, lightweight architecture. The device was also found to achieve “excellent” durability.
