Solar Power for Bishopscourt, Cape Town – 64 kW Residential Solar & Battery Installation

First Energy Solar Installers has completed a 64 kW solar and battery installation at a home in Bishopscourt, Cape Town – one of the largest residential systems in the Southern Suburbs. The array of 119 × 545 W glass-on-glass panels (64.9 kWp) feeds a 100 kW grid-tied inverter and three 10 kW hybrid inverters, and the system is expected to generate about 109,735 kWh a year – avoiding more than 45 tons of CO₂ annually.

The brief: run a large estate on solar, with backup

This Bishopscourt property has the consumption of a small commercial site – staff accommodation, pools, boreholes, irrigation, air-conditioning and multiple geysers. The brief was to cover the full daytime load with grid-tied generation and, separately, to keep essential circuits running through outages with battery-backed hybrid inverters.

The solution: a grid-tied array plus a battery-backed essential-loads system

• 119 × 545 W glass-on-glass solar panels (64.9 kWp)
• 1 × 100 kW three-phase grid-tied inverter for bulk daytime generation
• 3 × 10 kW hybrid inverters with battery storage for essential circuits
• 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

Splitting the system into a large grid-tied inverter and three battery-backed hybrids gives the owner cheap bulk generation during the day and seamless backup for lights, security, refrigeration and IT when the grid fails.

The results

• Estimated annual generation: 109,735 kWh – roughly 9,150 kWh a month
• Carbon avoided: over 45 tons of CO₂ per year
• Daytime load on solar; essential circuits protected by battery backup

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.

Frequently asked questions

Why combine a grid-tied inverter with hybrid inverters?
The grid-tied inverter generates bulk daytime power cheaply, while the hybrids and their batteries protect essential circuits during outages. It is the most cost-effective way to get both on a very large home.

Can a home system this size export to the City of Cape Town?
Yes, with a bi-directional AMI meter and SSEG approval. We design for self-consumption first, since the export rate is lower than the tariff you avoid.

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.
