UK developer announces 1.3 GW of solar capacity and 2 GWh of batteries
London-based – and apparently Moby Dick-inspired – Queequeg Renewables has revealed plans for a slew of solar projects and a string of battery plants which will provide grid balancing services.
EDP becomes largest shareholder of Sunseap
The operation is part of the Portuguese utility’s plan to deploy another 13 GW of renewable energy capacity by 2025.
Ingeteam showcases three-phase battery inverter for commercial and utility scale projects
The Ingecon Sun Storage 100TL battery inverter has an efficiency of 98.8% and a European efficiency rating of 98.1%. The device features maximum DC voltage of 1,100 V and an input voltage range of 570-850 V.
Flexible BIPV panel with 410 W output from Italy
Developed by cleantech company Verditek, the flexible module has a 20.1% efficiency and a weight of 4.9kg. It can bend up to 35% using standard 160µ-thick crystalline cells.
Cambridge scientists develop Zinc-ion battery that stores solar energy
U.K. researchers have developed a battery with a photocathode made of vanadium dioxide, which is used to harvest light and store zinc ions and zinc oxide as a charge transport layer. The device showed an efficiency of around 1.2% and capacity retention of around 73% after 500 cycles.
Scaling up perovskite-silicon tandem solar cell performance
Scientists in Germany investigated various routes to optimizing cell design for perovskite-silicon tandem products. Beyond the perovskite layer itself, they note several other areas that should be optimized for tandem cells, taking silicon heterojunction processing as a starting point. The research identifies several routes to cut costs in cell production, including a significant reduction in indium consumption.
How to clean PV systems covered by volcano ashes
Spanish company Multisistemas E2 has explained how PV systems affected by the volcano eruption in the Canary Islands are currently being cleaned.
Midsummer begins construction on 50 MW factory in Italy
The factory will be built with the financial support of the Italian government. It will mostly serve southern European markets.
Germany has installed 4 GW of PV so far this year
In June alone, new PV additions totaled 406 MW. Feed-in tariffs were reduced by another 1.4%.
Solliance hits 29.2% efficiency on perovskite/silicon tandem solar cell
The Solliance consortium has built a solar cell in a four-terminal tandem configuration that combines a 17.8%-efficient highly near-infrared transparent perovskite cell with a prototype of an 11.4%-efficient c-Si interdigitated back contact silicon heterojunction cell developed by Panasonic.
