What Services Does a Solar Panel Company Provide?
- Property Assessment: Installers will assess your roof and energy usage to ensure the system is sized correctly for specific needs.
- Solar Panel Installation: Physical installation of panels, inverters, and cabling, typically takes one day for standard residential properties.
- Post-Installation Testing: Technicians will perform tests to ensure the system is safe and performing as expected before commissioning.
Do I Need an SEAI-Approved Company to Receive a Grant?
Yes. Grant eligibility requires using an SEAI-approved company. This ensures:
- Grant Eligibility: Unregistered installations are ineligible for the €1,800 payment.
- Quality Assurance: Installers must comply with Domestic Technical Standards and Specifications.
- Paperwork Support: Registered installers provide necessary grant documentation.
Are There Grants for Solar Batteries?
While the specific SEAI grant for batteries was discontinued, they remain a high-value investment. A battery increases self-consumption from typically 30%-40% to 70%-90%.
What Is the Payback Period for a Solar System?
With the 2026 grant levels, the 0% VAT rate, and the Clean Export Guarantee (CEG), the typical payback period in Ireland is now 5 to 8 years. After this period, electricity becomes essentially free for the panels' 25+ year lifespan.
