5kW solar system: common questions
How much does a 5kW solar system cost in South Africa?
Our installed 5kW packages are listed on this page with live prices, including panels, battery, installation and the electrical CoC.
Is 5kW enough for a 3-bedroom house?
For essentials (lights, fridge, Wi-Fi, TV, gate) usually yes. If you want to run the geyser, pool pump or several aircons on solar, look at 8kW or 10kW.
What is the difference between the Luxpower and Deye 5kW kits?
Both use the same battery and panels. The difference is the inverter brand, which affects price, monitoring app and warranty support.
Can I start with 5kW and add more later?
Yes. You can add batteries or panels later, within what the inverter can handle. We plan for that at the assessment.
