Finding the right solar system in Zimbabwe can feel overwhelming, especially with so many different sizes and packages available.

At Sona Solar Zimbabwe, we specialize in helping homeowners, businesses, and institutions choose the perfect solution—whether you are looking for a reliable 1.5 kVA solar system for domestic use or a powerful 11 kVA solar system for larger properties and commercial needs.

Powering Every Lifestyle: A System for Every Need

A 1.5 kVA solar package is ideal for households that need to cover the basics such as lights, TVs, Wi-Fi, and small appliances. As you move up to a 3.5 kVA or 4.2 kVA system, you gain the capacity to power refrigerators, freezers, water pumps, and essential household gadgets with ease. Our mid-range 5.2 kVA and 6.2 kVA solar systems are popular with medium to large homes and small businesses in Zimbabwe, providing the flexibility to run multiple appliances at once—including washing machines, microwaves, and small air conditioners.

Practical Tips for Usage

Sum simultaneous loads and keep them below your system's conservative (PF 0.8) limit.
Use batteries to run loads at night or to help start high-surge appliances.
Time heavier appliances (AC, microwave, kettle, oven) during peak sun hours.
Check your inverter's surge rating for fridges, pumps, and compressors.

Summary: 1.5kVA is for essential loads. 3.5–6.2kVA can handle small to medium households with multiple appliances. 11kVA is suitable for larger homes, small commercial setups, multiple ACs, ovens, pumps, and EV charging.
