Solar Power for Bishopscourt, Cape Town – 50 kW Residential Solar Installation

First Energy Solar Installers has completed a 50 kW solar installation at a large home in Bishopscourt, one of the Southern Suburbs’ most established residential areas and a few minutes from our Kirstenhof head office. Seventy-two 550 W glass-on-glass panels feed a 50 kW Deye three-phase hybrid inverter, and the system is expected to generate more than 67,003 kWh a year – avoiding over 27 tons of CO₂ annually.

The brief: estate-scale solar for a large Bishopscourt property

Bishopscourt homes are large, with staff quarters, pools, boreholes, irrigation, air-conditioning and multiple geysers, so their consumption is closer to a small business than a typical house. The brief was to cover that load on a City of Cape Town three-phase supply, with the ability to add battery backup for outages.

The solution: 72 panels on a 50 kW three-phase hybrid inverter

• 72 × 550 W glass-on-glass solar panels (39.6 kWp)
• 1 × 50 kW Deye three-phase hybrid inverter, battery-ready
• Roof-mounted on aluminium rails with SSEG-compliant DC and AC protection
• Online monitoring of generation and consumption
• Certificate of Compliance and City of Cape Town SSEG registration handled by First Energy

A single 50 kW three-phase hybrid inverter balances the property’s load across all three phases and accepts a high-voltage lithium battery bank for backup, without the complexity of multiple single-phase units.

The results

• Estimated annual generation: 67,003 kWh – roughly 5,580 kWh a month
• Carbon avoided: over 27 tons of CO₂ per year
• Daytime loads across all three phases now run on solar

Actual savings depend on how much of the home’s consumption falls in daylight hours and on the applicable tariff, which is why we model every system on the client’s own usage before we quote. With a battery on the hybrid inverter, evening consumption and load-shedding cover come onto solar as well.

Frequently asked questions

How big a solar system does a large Bishopscourt home need?
Estate-scale homes with pools, boreholes and air-conditioning often need 30–60 kW of three-phase inverter capacity and 40–70 kWp of panels. We size from the home’s actual bills and a load study.

Can a battery be added to this Bishopscourt solar system later?
Yes. The 50 kW Deye inverter is a hybrid unit, so a lithium battery can be connected at any time for load-shedding backup and evening use without replacing the inverter.

Does a home solar system in Bishopscourt need to be registered?
Yes. Bishopscourt is supplied by the City of Cape Town, which requires all grid-connected systems to be registered as small-scale embedded generation (SSEG). First Energy prepares and submits the application as part of the installation.
