What customers say
Our bill went from R3 800 to R640. Load shedding came back for a week in July and the kids did not notice. The proposal showed exactly which appliances would run and for how long, and it was accurate.
Three quotes. Southwind was the only one that asked for twelve months of bills before sizing anything. Install took two days, City of Cape Town SSEG paperwork was handled for us.
Did not want a full system, just lights, wifi and the fridge through an outage. They did not try to upsell me. Installed in a morning, app works, done.
