10kW solar system: common questions
How much does a 10kW solar system cost in South Africa?
The live installed prices for our 10kW packages are on this page, including 12 panels, battery, installation and the CoC.
Why is the Luxpower 10kW two 5kW inverters?
It pairs two 5kW Luxpower inverters to make 10kW, which keeps the cost down while giving the same total capacity.
Is a 10kW system enough for a big house?
For most 4-bedroom homes, yes. If you use a lot of power at night, add battery storage rather than inverter size.
Do I need permission to install a 10kW system?
Grid-tied and hybrid systems must be registered with your supplier (City of Tshwane or Eskom in most of Pretoria). Estates also need HOA approval.
