Latest development report of photovoltaic energy storage 2020

How much solar PV capacity will be added in 2020?

Global solar PV capacity additions are expected to reach nearly 107 GW in 2020 in the main case, representing stable growth from 2019 (this forecast has been revised up by 18% from the market report update published in May).

What is the installed capacity of PV projects in 2020?

According to the data released by the National Renewable Energy Information Center, the installed capacity of household PV projects included in the scale of national financial subsidies in 2020 is 10.12 million KW, accounting for 65% of the new installed capacity of all distributed PV.

Are energy storage services economically feasible for PV power plants?

Nonetheless, it was also estimated that in 2020 these services could be economically feasible for PV power plants. In contrast, in , the energy storage value of each of these services (firming and time-shift) were studied for a 2.5 MW PV power plant with 4 MW and 3.4 MWh energy storage. In this case, the PV plant is part of a microgrid.

Should energy storage be integrated with large scale PV power plants?

As a solution, the integration of energy storage within large scale PV power plants can help to comply with these challenging grid code requirements 1. Accordingly, ES technologies can be expected to be essential for the interconnection of new large scale PV power plants.

When are PV installations included in the 2020 statistics?

For the purposes of this report, PV installations are included in the 2020 statistics if the PV modules were installed and connected to the grid between 1 January and 31 December 2020, although commissioning may have taken place at a later date.

What are the energy storage requirements in photovoltaic power plants?

Energy storage requirements in photovoltaic power plants are reviewed. Li-ion and flywheel technologies are suitable for fulfilling the current grid codes. Supercapacitors will be preferred for providing future services. Li-ion and flow batteries can also provide market oriented services.
