Background: An Post is establishing a Qualification System for the provision of the Supply and Installation of Solar Panels Nationwide. While the primary focus of this procurement is on Supply and Installation services, An Post reserves the right to seek support, maintenance, and/or ongoing enhancement services at a later stage in any call off tender, inclusion of this provision does not imply any commitment or guaranteed volume from An Post. Summary of Requirements: An Post is committed to reducing energy consumption, increasing the use of renewable energy and reducing carbon emissions across its property estate. As part of its ongoing energy and decarbonisation programme, An Post intends to establish a Qualification System for the installation, commissioning and maintenance during the applicable warranty period of Solar Photovoltaic (PV) systems at An Post properties throughout the Republic of Ireland. An Post has initially identified approximately 53 properties nationwide for the installation of Solar PV systems. These properties vary in size, building type, electrical demand, available roof area, electrical infrastructure and grid connection arrangements. Accordingly, individual Solar PV installations will vary in capacity and complexity. It is anticipated that projects delivered under the Qualification System will include installations across the applicable ESB Networks generator connection categories, including: • NC6 – Micro-generation: including three-phase installations up to and including approximately 11 kVA; • NC7 – Mini-generation: including three-phase installations above approximately 11 kVA and up to 50 kVA; and • NC8 – Small Scale Generation: including larger inverter-connected generation installations above approximately 50 kVA, subject to the applicable ESB Networks requirements.
