It depends heavily on your monthly usage, whether you want battery backup, and your province. Small backup-only systems can start in the tens of thousands of rand, while a full system that meaningfully cuts your Eskom or municipal bill and rides out load shedding typically costs more. Run your own numbers on the calculator for an estimate based on your actual usage.

Many well-sized residential systems pay for themselves within several years, depending on your usage pattern, tariff structure, and how much load shedding is costing you in lost productivity or spoiled food. The calculator's assumptions panel shows exactly how we work out your estimated payback period.

A grid-tied system without batteries is cheaper and still cuts your electricity bill, but it won't keep the lights on during an outage. A hybrid system with batteries costs more upfront but keeps essential circuits running.

Get quotes from more than one installer, check they're properly registered and insured, and ask for references from recent local jobs. To skip the guesswork, browse vetted installers on our sister directory, ADEO.
