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.

Research shows residential PV is becoming less attractive in Germany
Through a new methodology based on Decoupled Net Present Value (DNPV), a German research team has found that residential photovoltaic systems were not economically viable under most market conditions at the beginning of 2023. Although lower modules prices have significantly improved system profitability in recent months, several influencing factors that change over time may still have an impact on revenue.
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.
