Mobile PV-powered EV charging stations for commercial, industrial sites
United Kingdom-based 3ti Energy Hubs has launched a portable electric vehicle charging station for 12 cars that it delivers to commercial and industrial sites where demand exceeds supply.
KAUST, Helmholtz-Zentrum Berlin present 31.2%-efficient blade-coated perovskite-silicon tandem solar cell
The perovskite-silicon tandem device has a two terminal configuration and a 2D perovskite layers at the bottom interface. It was able to retain around 80% of its initial efficiency for 1,700 h.
New model to assess performance of building-integrated photovoltaics based on PCM
Researchers in China have analyzed the effect of phase change material on BIPV, and created an artificial neural network to forecast its effect on system temperature. The proposed approach reportedly achieved superior predictive performance compared to earlier methods.
Multiple designs of photovoltaic-thermal collectors
Scientists have modeled eight different kinds of PVT systems, some with a glass covers and some without. They found the worst efficiency was achieved in uncovered systems with parallel round tubes.
JinkoSolar announces new TOPCon solar modules with efficiency of 24.8%
The Chinese manufacturer said the new Tiger Neo 3.0 modules are available in two versions with outputs of 495 W and 670 W.
Equipping transport trailer fleets with solar PV for fuel savings
Dutch solar PV systems integrator IM Efficiency has launched a complete solar PV system that includes battery and energy management system to power electrical systems on freight carrying trucks and transport trailers.
Trina Solar claims 25.9% efficiency for large-area industrial TOPCon solar cells
The Chinese manufacturer said the result was confirmed by Germany’s Institute for Solar Energy Research in Hamelin.
Survey shows best fast MPPT techniques for PV
A group of scientists conducted a literature review of almost a hundred fast maximum power point tracking algorithms. They extracted ten representative algorithms and showed which of them works best under different scenarios.
German PV experts develop quality standard for solar modules
The new Solar Module Quality Standard is based on VDE SPEC 90038-1. It will guarantee that PV modules have been produced and tested according to uniform quality criteria.
New US rules support solar supply chain, manufacturing
New US incentives support solar manufacturers and encourage the domestic build-out of the earlier stages of the solar supply chain.
