Purpose and Scope of the NDMG Scheme

Commercial rooftop solar deployment in Ireland is accelerated through the Sustainable Energy Authority of Ireland (SEAI). Specifically, the Non-Domestic Microgen Grant (NDMG) provides financial assistance to help businesses and other sectors to install solar PV panels to generate electricity on site.

The scheme accommodates diverse commercial, public, and non-profit facilities:

• Eligible Sectors: Businesses, agricultural enterprises, public sector bodies, schools, community centres, and non-profit societies.
• Capacity Boundaries: Grant funding is available for systems up to a maximum 1000kWp.
• Maximum Financial Aid: Eligible entities can receive a government grant of up to €162,600.
• Oversized Systems: A solar PV system with an output of a maximum 1000kWp can be grant funded through the scheme; if the installed capacity exceeds this ceiling, the applicant may claim the maximum grant offering of €162,600.

Tiered Grant Valuation Structure

The grant amount you receive is based on the standard output of your solar PV system. The SEAI publishes a transparent, step-down rate table:

Under this stepped structure, small commercial installations cap at €2,400 for 4 kWp to 6 kWp arrays, before moving to capacity-based incremental additions for larger commercial roofs.

Application Rules, Timelines, and Grid Notice

Securing grant funding requires compliance with statutory administrative milestones:

1. Prior Letter of Offer: Installers must not start works until an official grant offer is issued. Grant offers are valid for eight months from the date you receive your 'letter of offer'.
2. ESB Networks Notification: Solar PV companies must coordinate grid permission. They must do this before installing the solar PV system. This application process takes at least 4 weeks / 20 working days.
3. Disbursement Turnaround: Following installation, all evidence of works must be submitted to the online portal. Please allow between 4 to 6 weeks for payment, with additional time if an inspection is required.
