Section 12B Solar Tax Deduction for Retail

Retail businesses face rising electricity costs that erode already-thin margins. A rooftop solar system paired with the Section 12B tax incentive can reduce your electricity bill while delivering a substantial first-year tax deduction.

Retail Energy Profile

Retail stores consume electricity consistently during trading hours for lighting, HVAC, and refrigeration. Solar generation aligns well with these daytime loads, typically offsetting 70-80% of peak usage.

How Section 12B Benefits Retail

A retail business investing R1.4 million in a 100 kW solar system can claim a R1.75 million deduction under Section 12B. This reduces taxable income substantially in year one, improving cash flow when it matters most.

Retail rooftops in shopping centres and standalone stores generally offer sufficient area for 100 kW systems. Pitched roofs may require specialised mounting, but flat roofs simplify installation and maintenance.
