Monthly savings example (illustrative)
A mid-size hybrid system that offsets a large share of grid use can reduce your municipal bill by roughly R1,500–R4,000+ per month depending on tariffs, self-consumption, and how much you rely on batteries during load-shedding. Savings are not guaranteed—ask installers to model kWh offset using your actual usage.
ROI and payback
Many homeowners see simple payback in the range of about 4–7 years when electricity tariffs rise and the system is sized to match real usage—not just the cheapest sticker price. ROI improves when you factor in fewer spoils from outages, predictable energy costs, and possible property appeal. Get itemised quotes that show estimated annual kWh production and projected savings so you can compare apples to apples.

Frequently Asked Questions
Installed systems commonly fall between about R45,000 and R260,000+ depending on whether you need a small backup setup, a mid-size hybrid, or a large home system with more battery storage. Exact pricing needs a site assessment.
For many households, yes—especially with rising tariffs and load-shedding. Value depends on your usage, tariff structure, system size, and how long you plan to stay in the home. Compare projected savings and payback on written quotes.
Most residential jobs take about 1–3 days on site once equipment is on hand. Complex roofs, long cable runs, or DB upgrades can add time. Your installer should give a written schedule.

Compare quotes, check reviews, confirm experience with your inverter/battery brand, and ensure compliance paperwork is included. Ask about warranties and after-sales support.
