Ecological Photovoltaic Energy Storage System Project

What is the IEA photovoltaic power systems programme?

The IEA Photovoltaic Power Systems Programme (IEA PVPS) is one of the TCP’s within the IEA and was established in 1993. The mission of the programme is to “enhance the international collaborative efforts which facilitate the role of photovoltaic solar energy as a cornerstone in the transition to sustainable energy systems.”

How do photovoltaic panels affect ecological responses?

Both the random forest model and mixed effects model highlighted key driving factors such as air temperature and humidity, location under the photovoltaic panel, monthly variations, geographical environment, and photovoltaic scale, which influenced the ecological responses to PVPPs.

What are the components of a photovoltaic system?

The system includes a 10 kWp multicrystalline-silicon photovoltaic (PV) system (solar irradiation about 1350 kWh/m2/year and annual yield 1000 kWh/kWp), an iron phosphate lithium-ion (LiFePO4) battery, and other components such as the control system, battery housing, and two inverters (one for the PV system and one for the battery system).

How do photovoltaic power plants affect the environment?

Changes in water and heat balance serve as the primary driving forces behind the heterogeneity of ecological environmental factors resulting from PVPPs, with this impact being more pronounced in larger and drier photovoltaic power plants.

How does photovoltaic development affect regional terrestrial ecosystem carbon flux?

The response of regional terrestrial ecosystem carbon flux to PVPPs under the influence of photovoltaic development is closely related to the original land use type, soil texture, and physicochemical properties of the underlying surface.

How does PV panel cleaning affect ecosystem respiration?

The dual effect of PV panel cleaning and gradual vegetation recovery increased air humidity within the photovoltaic field, intensifying the response of GPP and NEE to PVPPs. Furthermore, ecosystem respiration weakened as winter temperatures decreased.
