System role and load
The stated applications are Hotel and institutional hot water, Residential water heating, Industrial process pre-heating and Hospital and school facilities. Provide the system role, connected loads, duty, redundancy, future capacity and interfaces with existing equipment.
Ratings, compatibility and acceptance
Compare proposals against Daily hot water demand in litres, Required storage capacity, Collector type preference, Roof area, orientation and structure and Backup heating requirements. Require source-specific drawings, datasheets, protection or coordination information and the test/standard evidence called for by the project.
Installation, protection and support
Confirm enclosure and environmental conditions, cable/termination interfaces, dimensions and weights, transport protection, site access, installation boundaries, testing, commissioning, training, warranty expectations and spare components.
