Frequently Asked Questions
The questions South Africans ask us most, answered without a sales pitch.
How much does solar cost in South Africa?+
Renting replaces the upfront system cost with a fixed monthly fee, usually from around R1 200 per month. An onboarding fee might be applicable depending on the package and provider.
Do solar panels work when it rains?+
Yes, just at reduced output — typically 10% to 30% of rated capacity on heavily overcast days. Rain also washes dust off the panels, which improves performance afterwards. A correctly sized battery covers the shortfall on low-generation days.
Can solar eliminate my electricity bill?+
It can eliminate most of it. Fixed municipal service charges usually remain, and households with heavy evening loads or electric geysers may still draw from the grid in winter. An honest quote should show expected offset, not promise a zero bill.
What is included in the monthly fee?+
Installation, maintenance, monitoring and support are handled by your chosen rental company for the life of the agreement. An onboarding fee might be applicable.
How long does installation take?+
Most residential installations are completed in one to three days on site once the equipment is available. Allow one to four weeks from accepted quote to installation, plus municipal registration where required.
What size system do I need?+
It depends on your kWh usage and when you use it, not just your rand bill. As a rough guide: under R1 500 a month suits a 3.6kW inverter with 5kWh of storage; R3 000 - R5 000 typically needs 8kW with 10-15kWh. A proper assessment considers roof orientation, shading and appliance loads.
How long do solar batteries last?+
Quality lithium iron phosphate batteries are rated for 6 000 or more cycles, which is well over a decade at one cycle a day. Heat, chronic deep discharge and poor battery management shorten that. Check warranted cycles and retained capacity at end of warranty.
