Question 2

How many peak sun hours does Eerste River get?

Question 3

What is the solar payback period in Eerste River?

Accepted Answer

At R3.21/kWh and 4.9 peak sun hours/day, a 5 kW system in Eerste River (R70k–R105k installed) pays back in 4.4–6.3 years. With annual tariff increases of ~10%, the payback improves every year.

Question 4

Are there SAPVIA-registered solar installers serving Eerste River?

Accepted Answer

Yes. FlowLeads matches Eerste River homeowners with SAPVIA-registered solar installers who service the Cape Town area. All installers are vetted, hold valid ECSA COC certificates, and carry public liability insurance.

Question 5

Do I need a battery for solar in Eerste River?

Accepted Answer

A battery is recommended for Eerste River given Eskom load-shedding. Without a battery, the inverter disconnects from the grid during outages (a safety requirement). With a 5 kWh battery, you get 4–6 hours of backup per slot and self-consumption rises from 60% to 85%.
