Residential vs Commercial solar: Which installation is right for you?

As South Africa continues to face rising electricity costs and load shedding, an increasing number of people are turning to solar energy as a reliable and cost-effective solution. But when it comes to choosing the right solar system, one question often comes up: What’s the difference between residential and commercial solar installations, and which one is right for me?

At Solarwise Energy, we specialize in both residential and commercial solar solutions, and in this blog, we’ll break down the key differences, benefits, and considerations for each.

Residential Solar: Powering Your Home

Residential solar systems are designed for households that want to:

  • Reduce their monthly electricity bills.

  • Keep the lights on during load shedding.

  • Become less dependent on the grid.

Key Features of Residential Solar:

  • System Size: Typically smaller (3kW–10kW), depending on household usage.

  • Design Focus: Efficient power for appliances, lighting, and household comfort.

  • Storage Options: Often paired with batteries for backup during load shedding.

  • Benefits: Lower monthly bills, peace of mind, and long-term savings.

Residential solar is ideal for homeowners who want energy independence and the freedom to take control of their electricity supply.

Commercial Solar: Powering Your Business

Commercial solar systems are much larger and more complex, designed for businesses with high energy demands. From offices to factories and warehouses, these systems ensure that productivity doesn’t stop when the grid goes down.

Key Features of Commercial Solar:

  • System Size: Ranges from 20kW to several hundred kW, depending on business needs.

  • Design Focus: Maximizing savings and efficiency to cut operational costs.

  • Storage Options: Large-scale batteries or hybrid solutions to keep operations running.

  • Benefits:

    • Major reductions in monthly electricity bills.

    • No downtime during load shedding.

    • Improved sustainability credentials (great for brand image and compliance).

    • Tax benefits (up to 125% deduction with Section 12B).

Commercial solar is a smart investment for businesses looking to stay competitive, protect profits, and operate without interruption.

Which One Is Right for You?

  • If you’re a homeowner, residential solar is your answer to rising household costs and load-shedding frustrations.
