3kVA vs 5kVA: Which Solar System is Right for Your Zimbabwean Home?
Choosing between a 3kVA and a 5kVA solar power system is a critical decision for homeowners in Zimbabwe. This detailed guide explores the capabilities, components, and ideal applications of each to help you make an informed investment in your energy independence.

3kVA vs. 5kVA: A Head-to-Head Comparison
Generating 12-15 units (kWh) per day, the 3kVA solar system is the perfect fit for the average Zimbabwean family home. It is designed to power all essential appliances, ensuring your life continues without interruption during load shedding.
- Powers: All lights, a large fridge, a deep freezer, TV and entertainment, Wi-Fi, and chargers.
- Intermittent Use: Can comfortably handle a borehole pump or a microwave (one at a time).
Typical Components:
Inverter | 24V 3kVA Must Hybrid Inverter |
Battery | 25.6V 106Ah Lithium Battery |
Solar Panels | 3 x 460W JA Solar Panels |
Generating 20-25 units (kWh) per day, the 5kVA solar system is a high-capacity solution for larger homes, home offices, or small businesses. It provides the power needed to run multiple heavy-duty appliances simultaneously.
- Powers: Everything the 3kVA system can, plus more.
- Heavy Loads: Can simultaneously run multiple fridges/freezers, pumps, and even a small, energy-efficient air conditioner.
Typical Components:
Inverter | 48V 5kVA Must Hybrid Inverter |
Battery | 51.2V 100Ah Lithium Battery |
Solar Panels | 6 x 460W JA Solar Panels |
How to Correctly Size Your Solar System
The foundation of any solar system design is understanding your energy needs. The most accurate way is to review your ZESA bills for the past 12 months to calculate your average daily kilowatt-hour (kWh) consumption. This helps account for seasonal variations.
Zimbabwe is blessed with abundant sunshine, but the number of "peak sun hours" (the hours of optimal sunlight) varies by location and time of year. A professional installer from Sona Solar Zimbabwe will use this data to accurately calculate your system's potential daily generation.
Once your energy needs and sun hours are known, our certified electricians design the system. This involves selecting the right number of high-efficiency solar panels, choosing the correct inverter size (e.g., 3kVA or 5kVA), and sizing the lithium battery bank to provide the desired backup time.
The orientation and available space on your roof are critical. North-facing roofs are ideal in Zimbabwe. If your roof is not suitable, we can design efficient ground-mounted solutions to ensure maximum sun exposure and energy generation.

Frequently Asked Questions
The main difference is capacity. A 5kVA system can handle a higher total load of appliances running simultaneously. While a 3kVA system is perfect for a modern Zimbabwean home, a 5kVA system is better for larger homes or those with more power-hungry appliances like air conditioners or multiple pumps.
On average in Zimbabwe, a well-designed 3kVA system generates 12-15 kWh per day, while a 5kVA system generates 20-25 kWh per day. This is typically more than enough to cover the daily consumption of an average household.
Professional installation by a certified electrician is crucial for safety, efficiency, and to validate your equipment warranties. Sona Solar Zimbabwe ensures every installation comes with a Certificate of Compliance (COC), giving you complete peace of mind.
