16kW solar system: common questions
How much is a 16kW solar system?
Our 16kW Deye and Sunsynk packages are listed here with live installed prices, including 24 panels, about 20kWh of battery, installation and the CoC.
Is 16kW too big for my house?
It is sized for high-usage homes. If your bill is under a few thousand rand a month, a smaller system with more battery may suit you better.
How much roof space do 24 panels need?
Roughly 65 to 70 square metres of usable, mostly north-facing roof. On big stands a ground-mounted array is an option.
Can a 16kW system feed power back to Tshwane?
Tshwane limits how much a home may export, so large systems are set up to use their own power first rather than sell it back.
