- Grant approval is issued shortly after application
- Installation must be completed within the timeframe specified in the letter of offer
- Payment is issued once documentation is reviewed and approved
Processing times depend on application volume.

Grant levels are determined by SEAI policy and government funding allocations.
In recent years, grant amounts have reduced as solar adoption has increased. Homeowners considering solar often choose to act while current funding remains available.
Even with the reduced grant cap, solar can still deliver:
- Lower electricity bills
- Protection against rising energy prices
- Export payments for excess electricity
- Improved BER rating
- Long-term property value benefits
The grant helps reduce upfront cost, but the long-term savings depend on system size, energy usage and tariff structure.
