How Section 12B Benefits Warehouse/Distribution

A R2.8 million solar investment on a warehouse qualifies for a R3.5 million Section 12B deduction. At 27% tax, this puts R945,000 back into the business in the first year.

Corrugated metal roofs on warehouses provide vast unshaded areas for panel installation. Roof-clamp mounting systems attach directly to standing seams without penetrating the roof sheeting.
