Trinity House are approaching the market with a multi-lot tender for the supply of photovoltaic modules (solar panels).

The aim is to establish two or more framework agreements, for an initial 2 year period with an option to extend for a further 2 years, that primarily for use by Trinity House, but also provide the option for the Northern Lighthouse Board and the Commissioners of Irish Lights to procure solar modules from the successful tenderers against the terms of this agreement. Should a minimum of two not be achievable as a result of this tender process, Trinity House reserve the right to amend this figure by a tolerance of one.

There are 8 available lots and tenderers can bid for any applicable lot/s.

The access code for this requirement is Q77P6PUD63 and the tenderbox will close at 12.00 on Friday 9 August 2019.

These 12-volt solar photovoltaic (PV) modules are installed on remote, unmanned stations, vessels and buoys in coastal environments to serve as the power supply for marine aids to navigation (AtoN), particularly for use on Type 1 and 2 navigational buoys. These modules are required in a 1 m lead or a 2.5 m lead variation.

These modules will be installed on remote, unmanned stations, vessels and buoys in coastal environments to serve as the power supply for marine aids to navigation (AtoN). Long-term reliable operation of the equipment at these locations is essential.

Modules will be installed on remote, unmanned stations in coastal environments to serve as the power supply for marine aids to navigation (AtoN), primarily rock stations such as Eddystone and Farne Islands.

These modules are used on ground/roof based fixed frames at lighthouse sites. Despite their fixed nature, extended exposure to salt water spray in an off-shore environment is still present.

Mid power lighthouse solar modules. These modules are used on ground/roof based fixed frames at lighthouse sites with a smaller power demand. Despite their fixed nature, extended exposure to salt water spray in an off-shore environment is still present.

These modules will be installed on Type 1 modular superstructures, used in coastal environments to serve as the power supply for marine aids to navigation (AtoN). Long-term reliable operation of the equipment at these locations is essential.

These modules are primarily used on buoys and lightvessels and sites that are prone to wave wash, such as rock tower lighthouses. Consideration of these locations is important to the design of these modules.

Tenderers should confirm willingness to engage with Trinity House for the provision of ad-hoc research and development (R&D) services in the field of photo-voltaic modules. The research and development aspect relates to future requirements of Trinity House and the willingness of suppliers to support these areas for exploration through product design and development.
