We ran the Winter Special's numbers against 4 years of Eskom's own tariff data.
Your electricity is already about 72% more expensive than in 2022, and that trend isn't reversing β Eskom's own debt and maintenance backlog see to that.
R99,500 buys a full 12kW solar and battery system, installed: Luxpower 12kW inverter, 3x Hina ESS Hi-5 batteries, 12x 620W panels, full install kit and cabling β supplied, installed and COC'd.
On an example Pretoria East home spending ~R3,500/month on Eskom, offsetting ~85% of that usage saves about R3,000/month. At today's tariff alone that's under 3 years. Add a conservative 10%/year future increase (below the last 4 years' average) and payback lands closer to 2 years 7 months.
After that, every tariff increase pays you instead of costing you β over 10 years, roughly R573,000 back against a R99,500 cost. Illustrative example, not a promise, but the direction is clear.
