Solar energy storage refers to the process of capturing and storing excess solar energy generated by solar panels for use at a later time. This enables the utilization of solar power during periods without sunlight, such as at night or on cloudy days, ensuring a continuous and reliable energy supply. By storing surplus energy, users can reduce their dependence on the grid and lower electricity costs.
Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report's Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.
The main types of solar energy storage include lead-acid, lithium-ion, flow batteries, and others. Lead-acid batteries are a type of rechargeable battery that uses lead and sulfuric acid for energy storage. These systems can be installed both on-grid and off-grid and come in various capacities, including 50 kW, 51 to 250 kW, 251 to 500 kW, 501 to 1,000 kW, 1,001 to 2,500 kW, 2,501 to 5,000 kW, 5,001 to 10,000 kW, and > 10,000 kW. They are applied in residential, commercial and industrial, and utility sectors.

This solar energy storage market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.
The solar energy storage market size has grown rapidly in recent years. It will grow from$61.14 billion in 2024 to $70.76 billion in 2025 at a compound annual growth rate (CAGR) of 15.7%. The growth during the historic period can be attributed to the increasing demand for renewable energy integration into the grid, the growing adoption of solar power in residential and commercial sectors, a rising focus on energy self-sufficiency and independence, and the availability of government incentives and subsidies for solar and storage systems.
The solar energy storage market size is expected to see rapid growth in the next few years. It will grow to$125.24 billion in 2029 at a compound annual growth rate (CAGR) of 15.3%. The growth during the forecast period can be attributed to the increasing need for grid stability and reliability, the growing cost-effectiveness of lithium-ion and other advanced batteries, the rising deployment of smart grids and distributed energy systems, and growing concerns over carbon emissions and climate change. Key trends expected during this period include advancements in battery technology, the development of smart energy storage systems, improvements in energy management and optimization, and greater integration with electric vehicles.
The growing demand for renewable energy is expected to drive the expansion of the solar energy storage market. Renewable energy is derived from natural, replenishable sources such as sunlight, wind, water, and biomass. The increased demand for renewable energy is largely fueled by heightened environmental awareness, with concerns over climate change and the negative impacts of fossil fuels motivating both governments and consumers to seek cleaner, more sustainable alternatives. Renewable energy plays a crucial role in solar energy storage by ensuring a continuous power supply, storing excess solar energy for use during times when sunlight is unavailable, thus addressing the intermittent nature of solar generation. For example, in March 2022, the U.S. Energy Information Administration projected that the share of renewable energy in power generation would nearly triple, increasing from 21% in 2021 to 44% by 2050, largely due to the growth of wind and solar power. As a result, the rising demand for renewable energy is significantly contributing to the growth of the solar energy storage market.
Leading companies in the solar energy storage market are concentrating on the development of advanced technological solutions, such as utility-scale energy storage systems, to optimize energy management. A utility-scale energy storage system is a high-capacity, sophisticated technology solution designed to store and manage electricity at the grid level, improving energy reliability, efficiency, and the integration of renewables. For instance, in December 2023, Canadian Solar, Inc., a renewable energy company based in Canada, launched SolBank 3.0, a system featuring higher energy density and enhanced safety features for utility-scale applications. SolBank 3.0 is a compact, high-performance solar energy storage system capable of delivering 2.35 MW of power and a 5 MWh capacity. It incorporates high energy density cells, intelligent liquid cooling, and advanced safety systems to improve reliability. The system offers 45% more capacity and reduces commissioning time by 40% compared to the previous model. Additionally, its optimized thermal management reduces auxiliary power consumption by up to 30%, boosting overall efficiency.
