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.
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.
Climate data-based methodology for residential air-source heat pump sizing
A European research team proposed a new air-source heat pump sizing approach that utilizes long-term climate data and adjusts system operation based on actual local climate conditions. The sizing algorithm incorporates peak heat demand, unitary final energy demand, and seasonal heat demand across different house sizes.
