By Technology

The solar photovoltaic (PV) systems segment accounted for a market share of 60.27% in 2025 in the behind-the-meter (BTM) market, driven by economic and operational incentives. In regions with high electricity rates and demand charges, ESS enables consumers to store energy during off-peak periods and discharge during peak pricing, significantly reducing bills. Rising adoption of rooftop solar amplifies this effect by allowing excess solar generation to be stored rather than exported at low rates. Increasing grid instability and the desire for backup power boost demand. Supportive policies, declining lithium-ion battery costs, and corporate sustainability initiatives further accelerate ESS deployment in residential, commercial, and industrial settings.

The energy storage systems segment is expected to register a CAGR of 20.14% during the forecast period, driven by rising demand for natural and plant-based ingredients. Behind-the-meter (BTM) is increasingly used in skincare and haircare formulations due to its nourishing and protective properties. Consumers are shifting toward products that offer multifunctional benefits while avoiding synthetic chemicals. Beauty brands are incorporating Behind-the-Meter (BTM) into premium product lines to enhance appeal and differentiation. The segment is also supported by growing awareness of clean beauty trends and sustainable formulations. As demand for natural cosmetics continues to rise, this segment is expected to expand at a rapid pace.

By End User

The residential segment accounted for a share of 52.47% in 2025 due to multiple synergistic drivers. Declining rooftop PV costs have made solar installations financially accessible for homeowners, improving return on investment. The increasing adoption of solar paired with energy storage allows residents to maximize self-consumption and reduce reliance on the grid, especially during peak pricing. Supportive policies, rebates, and net metering programs further incentivize rooftop installations by providing financial benefits for excess energy export.

The commercial segment is expected to register a CAGR of 12.45% during the forecast period, driven by financial and strategic incentives. Businesses adopt BTM systems to reduce demand charges and overall energy costs, improving operational efficiency. Large rooftop spaces, typically ranging from 10 to 500 kW, allow for substantial on-site generation, increasing self-consumption and lowering utility dependency. Corporate sustainability goals and ESG commitments encourage companies to invest in renewable energy solutions to reduce carbon footprints and enhance brand reputation.
