Technical FAQs 4

What is PV Grid parity?

Grid parity is defined as the equivalence of the cost of electricity from PV power generation with that of conventional energy power generation [9, 10]. Some countries have already achieved PV grid parity (e.g., Chile and Egypt) [11, 12].

What is grid parity?

As we peer into the horizon of energy's future, the concept of grid parity stands as a pivotal benchmark in the evolution of power generation economics. Grid parity occurs when an alternative energy source can generate power at a levelized cost of energy (LCOE) that is less than or equal to the price of purchasing power from the electricity grid.

What is grid parity index?

Grid parity index Grid parity can be further categorized into the demand-side (retail electricity price) and supply-side (conventional energy generation costs) grid parity.

When will solar PV systems reach grid parity in China?

Finally, the PV systems in different regions in China are expected to achieve grid parity between 2020 and 2032. In other words, within the next decade, grid parity of solar PV systems in China is forecasted to be achieved.
