I wouldn't waste my money on solar powered lights as scattering a bunch of batteries around the property without any temperature control or proper battery management circuits is going to kill any battery very quickly.
If you want a battery backup solution to cater for load shedding at night then having a larger central battery indoors where the temperature can be managed and kept within operating limits and having a decent charger/inverter would last way longer.
If no battery backup solution is required then use day-night sensor bulbs or if you want to save money use a
day-night sensor switch and wire a bunch of lights onto the circuit. Then you can replace standard LED bulbs at R40 to R60 each instead of R120 for the bulbs with the integrated day-night sensors.
