An MPPT (Maximum Power Point Tracking) charge controller extracts up to 30% more power from your solar panels compared to older PWM controllers. If you're building or upgrading a solar system, MPPT is the way to go. It pays for itself quickly in extra energy harvested — especially on cloudy days.

Lead-acid batteries are cheaper upfront but need more maintenance and have a shorter lifespan. Lithium (LiFePO4) batteries cost more initially but last 3–5x longer, charge faster, and perform better in heat. For most South African homes, lithium is the smarter long-term investment.

Monocrystalline panels are more efficient and last longer, making them ideal for homes with limited roof space. Polycrystalline panels cost a bit less and still do a great job. The best choice depends on your budget, roof size, and energy needs.
