Off-Grid Solar Systems for Northern Johannesburg Properties

True off-grid solar means powering your home entirely from sun and battery — no Eskom connection, no monthly bill, no load-shedding ever. It is technically more demanding than hybrid (you cannot fall back on the grid when you misjudge a cloudy week), but for smallholdings, farms and properties without reliable grid supply it is the only sensible answer. Apple Plumbing & Electrical engineers off-grid systems across Northern Johannesburg, Midrand and surrounding semi-rural areas.

What we do

Off-grid systems require oversizing — typically 12–25kW of panels paired with 20–40kWh of LFP storage and an optional generator changeover for winter back-up. We do detailed consumption modelling (every appliance, daily kWh, worst-month sun hours), recommend conservative sizing, and install full grid-isolated systems with appropriate transfer switching.

Signs you need this service

• Smallholding or property without grid connection
• Grid quote from City Power exceeds R100,000
• Permanent Eskom outages in your area
• Want true energy independence
