What are the criteria for energy performance evaluation of active solar technologies?
Criteria for energy performance evaluation of active solar technologies are screened. Energy criteria for ST, PV and PVT panels are categorised and discussed. Energy, primary energy and exergy criteria are the most used ones.
The lack of extensive data analysis on existing photovoltaic panels (PVPs) can lead to missed opportunities and benefits when optimizing photovoltaic power plant (PVPP) deployment solutions. The feasibility study of the PVPP requires accurate data on PVPs in order to fully unleash their potential.
Parameters of photovoltaic panels (PVPs) is necessary for modeling and analysis of solar power systems. The best and the median values of the main 16 parameters among 1300 PVPs were identified. The results obtained help to quickly and visually assess a given PVP (including a new one) in relation to the existing ones.
The growth of the PVPP market determines the growth of photovoltaic panel (PVP) production. However, in each case, it is necessary to investigate the efficiency of PVPs and the overall performance of the systems in order to select the best PVPs for installation in a specific geographic location.
