What is a significant PV surplus?
For cases with significant PV surplus, fifth of the cases exhibited more than h of PV surplus with an average PV surplus duration of 3.4 to 4.9 h daily. In terms of surplus energy, seven cases had over 1 GWh of PV surplus energy throughout the year, representing a substantial PV surplus that must be managed.
Will energy storage costs decrease in the future?
As the energy storage market continues to expand, the costs of both short- and long-duration storage are expected to steadily decrease in the future owing to economies of scale and learning curves. On this account, this subsection analyzes the changes in asset deployment and system economics resulting from the reduction in storage costs.
Is PV surplus energy a seasonal fluctuation?
Moreover, monthly analysis of the PV surplus unveils valuable insights into seasonal fluctuations. The aggregated results show that PV surplus energy (PVsE) during peak months are up to eight times higher than during low months such as January.
Is there a correlation between accumulated PV surplus and building types?
The study identified certain levels of correlation between the accumulated annual PV surplus and building types. Light-industry buildings show higher values in both PVsE and PVsH because of the relatively lower production energy demands, hence a higher chance of PV surplus in both occurrence and energy volume.
What is the unit power generation cost of a PV module?
The unit power generation cost of the PV module is represented by Cpv, which is set to 5.5 RMB/W based on the IEA (International Energy Agency, ) standards . Ppv denotes the power per unit area of the PV module, which varies depending on the PV material utilized.
Are solar PV projects reducing the cost of electricity in ?
Between and , utility-scale solar PV projects showed the most significant decrease (by 12%). For newly commissioned onshore wind projects, the global weighted average LCOE fell by 3% year-on-year; whilst for offshore wind, the cost of electricity of new projects decreased by 7% compared to .
