The IRS considers a solar system "placed in service" when it is ready and available for its intended use.
Your solar system qualifies as "in service" in 2024 and is eligible for the residential clean energy credit because the system:
- was fully installed in 2024
- was fully operational and generating power for your home use
- has passed local inspections and received necessary permits
- has been paid for in full
Be sure to keep all documentation showing:
- installation completion in 2024
- full payment
- permits
- system specs
