Cable Ties are the polymeric UV and heat-resistant cable ties used to secure the PV module leads or PV string cables.

Calculation

\[ n_{ties}= 1.03 \times ((2 \times n_{modules}) +(1 \times n_{strings}) + (6 \times n_{tables})) \]

where:

\[ \begin{align*} n_{ties}&=\text{Number of cable ties} \\ n_{modules}&=\text{Number of PV modules} \\ n_{strings}&=\text{Number of PV strings} \\ n_{tables}&=\text{Number of PV tables} \\ \end{align*} \]

✎️️ This quantity is estimated and can be adjusted with no impact on the design outcomes.
