Optimizing residential PV-driven heat pumps with lithium-ion batteries reduces LCOE by 7%
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%.
Solar Stack launches US-made penetration-free conduit mounts
Solar Stack has launched two US-made, adhesive-based conduit mounts that eliminate the need for roof penetrations in solar installations.
Low-temperature solar cell interconnection tech based on conductive coated wires
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.
FOB China module prices rise amid growing market expectations of sharp correction by end-Q2
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.
Carbon battery startup aims to make energy storage circular
SorbiForce, a Ukrainian energy storage company now in Arizona, has developed metal-free organic batteries made entirely from agricultural waste.
InfinityPV unveils slot die coater for thin-film PV research
The customizable, compact sheet coater supports coating speeds from 1.2 mm/sec up to 33 mm/sec.
Determining mismatch losses in bifacial PV based on single-axis trackers
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.
Segula presents compressed air storage system for residential applications
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 introduces new rules for energy communities
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.
Waaree Energies to double its solar module manufacturing in Texas
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.
