What Is Different In Big Bay
- Wind loading. Big Bay sees strong wind. Mounting should be designed for the wind load on the roof, with the right clamp spacing and fixings, and exposed or larger systems need an engineer's check.
- Salt air. Sites near the sea in Big Bay need corrosion-resistant rails, stainless fixings and isolation between dissimilar metals. Get it specified in the quote, and check it does not void the mounting warranty.
- Sectional title and multi-storey buildings. Roof space is often small compared with the building's load, so systems usually cover common property such as lifts, pumps and lighting, with batteries for backup. Trustee or AGM approval and crane access need to be sorted early. See Solar for Body Corporates Cape Town.
- Hospitality loads. Hotels, guest houses and restaurants use a lot of power in the evening, when solar is not producing. Most need batteries or heat-pump hot water alongside solar to get a worthwhile saving. See Commercial Battery Storage Cape Town.
Approvals For Big Bay Sites
- Supply authority. Big Bay falls under the City of Cape Town, so grid-connected systems and battery-only systems need City SSEG authorisation before installation. A few properties are supplied directly by Eskom and apply to Eskom instead; your electricity bill shows which. See Commercial Solar SSEG Registration Cape Town.
- Certificate of Compliance. Issued by a registered electrician for the electrical installation.
- Engineer sign-off. Needed for larger systems and structural checks.
- NERSA registration. Required for grid-connected generation above 100 kW.
Requirements and fees change. Ask each installer to confirm current requirements for your property in writing.

Frequently Asked Questions
How much does commercial solar cost in Big Bay?
Indicative installed ranges, excluding VAT, are about R350,000 to R500,000 for a 30 kWp grid-tied system and R1,000,000 to R1,450,000 for 100 kWp. Batteries add roughly R4,000 to R8,500 per kWh.
Do Big Bay businesses apply to the City of Cape Town or Eskom?
Most Big Bay properties are supplied by the City of Cape Town and apply for SSEG authorisation there. Properties supplied directly by Eskom apply to Eskom. Your electricity bill shows your supplier.
Is wind a problem for solar panels in Big Bay?
Wind affects the mounting design rather than the panels. Installers should calculate the wind load for your roof and size clamps, rails and fixings to suit, with an engineer signing off larger or exposed systems.
Does sea air affect solar systems in Big Bay?
It shortens the life of cheap mounting hardware and fixings. Ask for corrosion-resistant rails, stainless fasteners and inverters rated for the enclosure they are installed in, and check the warranty conditions for coastal sites.
Can an apartment block in Big Bay install solar?
Yes, usually for common-property loads such as lifts, pumps, gates and lighting. The body corporate needs the right trustee or member approval, and roof access, crane lifts and wind loading on higher roofs affect the price.
What size solar system do apartment blocks in Big Bay usually need?
It depends on daytime electricity use and roof space rather than building type alone, but apartment blocks commonly start around 50 kWp. Twelve months of electricity bills let installers size it properly.
