7. ELECTRICAL DESIGN CONSIDERATIONS

SECT locates pairs of modules in a ‘back-to-back’ orientation to decrease wind loads. Each

module faces a different direction and therefore receives different solar insolation, so must be

located in separate strings (unless module level power electronics are used).

The remaining electrical installation, including DC cabling, DC isolators, inverter and AC

cabling; is conducted using standard solar PV installation methods and procedures.

The SECT frame is fabricated from mill-finish aluminium, requiring only a single earthing

attachment per pod.

8. MAINTENANCE

The mill-finish aluminium used in SECT is largely maintenance free. Only in highly polluted or

marine conditions is rinsing with clean water required, during scheduled panel cleaning.

Further information regarding our systems is available on our website:

under Downloads in the solar section.
