When the power goes out, will your home be ready? With energy independence becoming increasingly important and utility rates climbing, more homeowners are turning to solar battery storage solutions. The Panasonic EverVolt battery system has emerged as a leading choice, but understanding the true cost requires looking beyond the sticker price.
In this comprehensive guide, you’ll discover everything you need to know about Panasonic solar battery pricing in 2025, including equipment costs, installation fees, available incentives, and how it compares to competitors. We’ll break down real-world pricing scenarios and help you determine if the EverVolt system delivers value for your investment.
Important Note: Panasonic announced in late April 2025 that they would be exiting the solar and battery storage business in North America. While they’ve committed to honoring existing warranties and supporting current customers, this decision impacts pricing and availability. We’ll address these implications throughout this guide.
Our analysis is based on current market data, installer quotes from multiple regions, and direct manufacturer specifications to provide you with the most accurate pricing information available.
Panasonic EverVolt Battery Pricing Breakdown
Understanding Panasonic solar battery pricing requires examining multiple system configurations and capacity options. The EverVolt system uses a modular design, allowing homeowners to customize their energy storage to match their specific needs.
Current 2025 Pricing by System Size
Based on our research across multiple markets and installer quotes, here are the current Panasonic EverVolt battery prices:
- 9 kWh system (2 modules): $9,500 – $12,000
- 13.5 kWh system (3 modules): $12,000 – $15,000
- 18 kWh system (4 modules): $15,000 – $18,000
These prices reflect equipment costs only and don’t include installation, permits, or additional electrical work. The modular design means each 4.5 kWh battery module adds approximately $2,500 – $3,000 to the total system cost.
Installation Costs and Labor
Professional installation is required for Panasonic EverVolt systems, and labor costs vary significantly by region and installation complexity:
- Basic installation: $2,000 – $3,000
- Complex installation: $3,000 – $4,000
- Electrical upgrades: $1,000 – $2,500 additional
Installation complexity depends on factors like your home’s electrical panel capacity, distance from the main panel, and whether you’re installing AC-coupled or DC-coupled systems.
Price Per kWh Analysis
When evaluating battery storage costs, price per kilowatt-hour provides a useful comparison metric:
- Panasonic EverVolt: $1,055 – $1,333 per kWh (equipment only)
- Industry average: $1,300 per kWh installed
- Total installed cost: $1,300 – $1,800 per kWh
While Panasonic’s pricing sits in the middle-to-upper range of the market, the system’s 12-year warranty and modular flexibility can justify the premium for many homeowners.
Regional Pricing Variations
Panasonic EverVolt pricing varies across different U.S. markets due to local labor costs, permit fees, and installer competition:
- California: 10-15% above national average due to high labor costs
- Texas: 5-10% below national average with competitive installer market
- Northeast: At or slightly above national average
- Southeast: 5-10% below national average in most markets
Factors Affecting Panasonic Battery Costs
Several variables influence the final price you’ll pay for a Panasonic EverVolt system. Understanding these factors helps you budget accurately and make informed decisions.
System Capacity and Modular Design Impact
The EverVolt’s modular design affects pricing in several ways:
- Economies of scale: Larger systems offer better per-kWh pricing
- Installation efficiency: Installing more modules at once reduces labor costs per kWh
- Future expansion: Adding modules later costs more than installing them initially
Most installers recommend sizing your system for current needs plus 20-30% growth to avoid costly future expansions.
AC vs DC Coupling Cost Differences
Panasonic offers both AC-coupled and DC-coupled EverVolt systems, each with different cost implications:
DC-Coupled Systems:
- Lower equipment costs when installed with new solar
- Higher efficiency (94% vs 90%)
- Requires compatible solar inverter
- Best for new solar installations
AC-Coupled Systems:
- Higher equipment costs due to additional inverter
- Compatible with existing solar systems
- More installation flexibility
- Ideal for retrofit applications
Installation Complexity Factors
Several site-specific factors can increase installation costs:
- Distance from main panel: Longer wire runs increase material and labor costs
- Electrical panel upgrades: Older panels may need replacement ($1,500-$3,000)
- Permit requirements: Local jurisdiction fees vary from $100-$500
- Structural considerations: Wall mounting vs. ground installation affects labor time
Geographic Location and Installer Markup
Your location significantly impacts total system costs:
- Labor rates: Vary from $75/hour in rural areas to $150/hour in major cities
- Permit fees: Range from $100 in small towns to $1,000+ in major metropolitan areas
- Installer competition: More competition typically means better pricing
- Local incentives: State and utility programs can offset higher base costs

Incentives and Savings Opportunities
Federal, state, and local incentives can significantly reduce the net cost of your Panasonic EverVolt system.
30% Federal Solar Tax Credit
The federal solar Investment Tax Credit (ITC) provides a 30% tax credit for battery storage systems installed through 2032. However, Congress has proposed terminating the 30% tax credit for residential solar and battery storage as part of budget reconciliation, with the Senate proposing to end the credit 180 days after the bill is signed into law, potentially by January 2026:
- Standalone batteries: Must store at least 3 kWh to qualify
- Solar-plus-storage: Entire system qualifies for credit
- Credit amount: 30% of total system cost including installation
- Example: $18,000 system = $5,400 tax credit
- Important: Systems placed in service by December 31, 2025 are expected to still qualify for the 30% tax credit. For the latest updates on potential changes to the federal tax credit, see our comprehensive guide to the 2025 solar tax credit situation.
