Sitework – Information for Site Foreman / Main Contractors
Some of the key points regarding the installation:
•
The solar roof requires both vertical counterbattens, and horizontal battens (25 x 50)
•
The vertical counterbattens must be laid over the breather membrane
•
Insulation is laid between the counterbattens before nailing the horizontal battens
•
Special attention must be paid to the eaves detail where the solar slates start at the
eaves – see relevant diagram
•
Solex or our contractors do not supply batten – this must be provided on-site
•
When Solex or our contractors arrive on-site we expect the roof to be complete to the
membrane and counterbatten stage (i.e. watertight)
•
Absorbers must be pressure tested with air before and during fitting the slates/tiles
•
Ridges and hips may be wet or dry fitted against the solar slates, and are usually
installed when finishing the conventional roofing, after the solar roof has been finished
•
Mortared ridges/hips sometimes leach lime or salts which stain the glass. This may be
removed with dilute hydrochloric acid, although it will weather off within 6 months
•
The system requires pipes (generally 2x 22mm for systems <70m
2
) and a cable
(generally 1x 2 core) running to the roof
•
The system requires a vented expansion tank (supplied by Solex) located at least
500mm below the level of the bottom of the solar roof, and not more than 4m from the
top of the solar roof. Brackets are available for wall mounting.
•
Sizing is usually as follows:
•
The expansion tank requires a cold fill supply, an overflow and must be accessible for
maintenance
•
Thermal stores, where supplied, are generally large, so provisions must be made for
handling (see delivery information above)
•
Consideration must be given to access arrangements for thermal stores, and weight
loadings of floors (they stand on three metal feet). See the thermal store specifications
toward end of this guide.
•
Thermal stores (1.5 bar) require a feed & expansion tank (not supplied by Solex). 3.0
bar stores may also be installed as a pressurised system subject to meeting
regulations.
