What does this research mean for the field?

The financial payback of PV-coupled battery storage is highly context-dependent, driven by retail-to-export price spreads and revenue stacking, while vehicle-to-grid (V2G) integration typically acts as a substitute for stationary storage capacity rather than an addition to it. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Synthesize evidence on the financial payback, return on investment, and primary economic drivers of solar-coupled battery storage systems, including the role of vehicle-to-grid integration.

Overview

Systematic review reveals wide payback ranges and vehicle-to-grid substitution effects in solar battery systems, highlighting the necessity of integrated revenue-stacking models.

Key Points

Synthesize evidence on the financial payback, return on investment, and primary economic drivers of solar-coupled battery storage systems, including the role of vehicle-to-grid integration.
Screened 122 peer-reviewed Q1/Q2 journal articles published between 2016 and 2026 across Scopus, Web of Science, IEEE Xplore, and MDPI databases.
Categorized articles into ten thematic clusters, evaluated reporting quality against a ten-criterion transparency rubric, and performed a narrative synthesis.
Reported financial payback periods ranged from a few years to beyond an asset's usable lifespan, while the levelized cost of storage spanned 170 to 350 USD/MWh.
Financial returns consistently improved with higher retail-to-export tariff spreads, degradation-aware dispatch algorithms, and the stacking of self-consumption, arbitrage, and grid services.
Harmonized comparisons indicated that vehicle-to-grid capabilities typically substitute for stationary battery capacity rather than serving as an additive revenue asset.
