Distributed photovoltaic energy storage development status

Are distributed solar PV systems better than large-scale PV plants?

In recent years, the advantages of distributed solar PV (DSPV) systems over large-scale PV plants (LSPV) has attracted attention, including the unconstrained location and potential for nearby power utilization, which lower transmission cost and power losses .

Is distributed PV a good investment?

Distributed PV is a pillar of clean energy transitions around the world, providing benefits for consumers and the climate. There are also economic upsides: Rooftop solar PV, the power generation technology that requires the most labour to install, is an engine for job growth. Momentum is substantial.

How will digitalisation impact distributed PV deployment?

Distributed PV deployment is expanding fast, accelerating the clean energy transition while calling for an increased focus on how to manage this growth. Digitalisation, an integral part of energy policy making, will ensure emerging risks from rapid distributed PV deployment are managed, and the benefits are fully unlocked.

Is energy storage a viable option for utility-scale solar energy systems?

Energy storage has become an increasingly common component of utility-scale solar energy systems in the United States. Much of NREL's analysis for this market segment focuses on the grid impacts of solar-plus-storage systems, though costs and benefits are also frequently considered.

How can digital tools help manage distributed PV installations?

Digital tools to analyse data from bi-directional smart meters (which measure both electricity flows from the grid to consumers and from distributed PV to the grid) can help detect the location of distributed PV installations and provide visibility on customers’ generation and consumption patterns.

Can distributed PV be integrated into the supply mix?

Digitalisation is already supported by the imperative to reduce technical and commercial losses, optimise commercial operations, and lower costs. The tools to address these issues, however, may not be well suited to easing the integration of distributed PV into the supply mix.
