Compare Solar Installation QuotesWhat Drives Commercial Solar Prices Cape Town Quotes
- System capacity. Price per kWp falls as systems grow because design, mobilisation and electrical costs are spread further.
- Batteries. The single biggest cost addition. Storage costs more per kWh than solar generation.
- Inverter capacity and type. Hybrid inverters and PCS units cost more than grid-tie string inverters.
- Roof type and structure. Ballasted flat-roof frames, structural reinforcement or re-sheeting add materially.
- Height and access. Multi-storey buildings need cranes or hoists and more safety equipment.
- Electrical infrastructure. Distance from array to main board, switchboard upgrades, and medium-voltage connections.
- Engineering and compliance. Structural and electrical engineering, SSEG and NERSA paperwork, meter changes.
- Equipment tier. Module and inverter brand, local support and warranty length.
- Monitoring and EMS. Basic inverter monitoring versus site-wide energy management.
What Is Usually Included - And What Is Not
| Usually included | Often excluded or provisional |
|---|---|
| Panels, inverters, mounting | Roof repairs or re-sheeting |
| DC and AC cabling and protection | Main switchboard upgrades |
| Installation labour and scaffolding | Meter replacement or tariff change costs |
| Certificate of Compliance | Structural reinforcement |
| Commissioning and handover | Fire suppression for batteries |
| Basic monitoring | Generator integration |
Estimating Savings From The Price
Multiply estimated annual production by what each kWh costs you, then reduce it for any production you cannot use on site. Exported kWh are credited at the feed-in rate, which is far below the purchase rate. Commercial grid-tied systems at sites with strong daytime use commonly pay back in about 4 to 7 years.
Tax And VAT
VAT-registered businesses can generally claim input VAT. Section 12B allows a 100% first-year deduction for qualifying PV up to 1 MW. Both reduce the effective cost substantially; confirm with your accountant.
Comparing Quotes
- Put every quote on a price-per-kWp basis, then check what is excluded.
- Compare estimated annual kWh, not just capacity.
- Check inverter and battery warranties, not only panel warranties.
- Ask whether SSEG approval and engineering sign-off are included.
