Revenue mapping and installation volume analysis were implemented to determine global market valuation. The methodology comprised the following:
• Identification of over 40 significant manufacturers in North America, Europe, Asia-Pacific, and Latin America who specialize in residential battery systems and integrated solar-storage solutions
• Product mapping for lithium-ion and lead-acid chemistry types, power ratings (up to 6 kW and 6-10 kW segments), ownership models (customer-owned, utility-owned, third-party-owned), and connectivity types (on-grid versus off-grid configurations)
• Examination of the annual revenues that have been reported and modeled for residential energy storage portfolios, which include hardware sales, installation services, and software/energy management systems
• Manufacturers and integrators that account for 75-80% of the global market share in 2024 are included.
• Segment-specific valuations for battery technologies and ownership structures are derived through extrapolation using bottom-up (residential installation volume × average selling price × storage capacity by country) and top-down (manufacturer revenue validation and utility program deployment data) approaches.
