Market guide
Price the installed battery and ownership path
Keep equipment, labor, panels, permits, software, warranty and service on one quoteBattery prices are not directly comparable until the scope matches. A complete quote identifies every configured component, backed-up load, site assumption, permit, utility task, commissioning step, warranty responsibility and excluded condition.
01
Quote
Normalize equipment and installed scope
Separate the current equipment sum from design, labor, panel work, trenching, structural protection, permits, utility fees, taxes and restoration.
- Price the configured capacity
- Record module count, usable energy, sustained and peak power, inverter, gateway, load controls, monitoring and every required accessory.
- Write the exclusions
- Unknown service upgrades, hazardous-material work, long conduit runs, fire barriers, internet work and generator integration should not hide outside the comparison.
02
Ownership
Price software, throughput and service
Compare warranty years, retained capacity, throughput or cycle terms, labor, travel, replacement path, firmware, cloud features and installer availability.
- Hardware warranty is not complete service
- Ask who diagnoses, removes, ships, replaces, recommissions and restores the system and what labor or travel the warranty excludes.
- Expansion can change compatibility
- Later modules may require matched generations, firmware, space, new permits or a larger inverter and cannot be assumed available.
03
Economics
Keep incentives and savings date-specific
Tax, utility, virtual-power-plant and tariff outcomes depend on eligibility, ownership, placed-in-service date, program terms and professional advice.
- Federal terms changed
- Current IRS guidance says the section 25D residential credit is unavailable for property placed in service after December 31, 2025.
- No quote guarantees savings or runtime
- Model tariffs, degradation, reserve, outages, solar, generator use and household loads, then retain the assumptions separately from the sale proposal.
