🔆 1️⃣ Project Overview
This Silver Lakes family wanted a long-term power solution that reduces energy bills and builds true independence from the Eskom grid.
Our team designed and installed a fully optimised 16kW hybrid solar system tailored to their home’s daily energy usage.
The system runs off-grid under normal conditions, with grid power configured as a failover backup for cloudy or high-demand days — ensuring complete reliability and energy security.
Project Summary:
- Client Type: Homeowner
- Location: Silver Lakes, Pretoria East
- System Size: 16kW Inverter | 30kWh Battery Backup | 19.8kWp PV
- Client Goal: Lower electricity costs and achieve long-term energy independence
⚙️ 2️⃣ Equipment Used
This system was built using top-tier components for maximum performance and longevity:
- Inverter: 16kW Sunsynk Hybrid Inverter
- Panels: 32 × 620W JA Bifacial Solar Panels
- Batteries: 3 × 10kWh Eenovance Lithium Batteries
- Mounting: Tile Roof Aluminum Rail System
- Extras:
- App-based system monitoring
- 24/7 technical support & remote monitoring under a maintenance agreement
- Solar Geysers installed for complete household energy optimisation
Each component was carefully selected and integrated by our skilled technicians to deliver efficiency, safety, and long-term reliability.
🏗️ 3️⃣ Installation & Challenges
The project was completed over five days by our professional team.
Due to tight roof spacing, panel alignment had to be meticulously planned to avoid shading during late afternoons.
The roof’s fragmented design, consisting of several smaller planes, added layout complexity — so we installed additional panels to maintain optimal generation.
We also rerouted wiring for minimal visual impact and created a clean, accessible inverter wall despite the limited space. Every detail was refined to balance aesthetics, performance, and functionality.
⚡ 4️⃣ System Optimisation
After installation, our engineers calibrated the system to ensure maximum efficiency and seamless performance.
Key optimisations included:
✅ Adjusted panel angles to improve winter generation
✅ Scheduled pool pump and geysers to run between 10:00–15:00, during peak solar hours
✅ Replaced conventional air conditioners with inverter-based models, saving approximately 1 000W per hour
✅ Fine-tuned inverter charging profiles to enhance battery life and ensure smooth power transitions
These fine adjustments deliver consistent performance and improved daily savings for the client.
📊 5️⃣ Performance Graph

Green – Solar generation | Red – Home load consumption | Yellow – Grid usage
This system consistently produces around 42kWh per day, fully covering the home’s daytime power needs and drastically reducing grid dependency.
💰 6️⃣ Results & Savings
- Daily Solar Yield: ±42kWh
- Monthly Eskom Savings: ±R5 804,50
- Estimated ROI: ±4.5 years
- Backup Duration: Up to 16 hours during power outages
These savings make the system not just a power upgrade, but a smart financial investment for long-term stability and independence.
