What Size Solar System Do You Actually Need? Avoid Overpaying!


One of the most common questions we hear at Sona Solar Zimbabwe is this: “What size of solar system is right for me?” It might seem like a simple question, but the truth is, many people in Zimbabwe end up buying too much or too little solar power for their needs. That’s a mistake that can cost you a fortune or leave you powerless when it matters most.
What Size Solar System Do You Actually Need? Avoid Overpaying!


Whether you’re just getting started or looking to upgrade, let’s break down the most common solar sizes 1.5kVA, 3.6kVA, 5.2kVA, and 8kVA and help you choose wisely.

Start by Understanding Your Energy Habits


Before diving into kVA sizes, it’s important to reflect on how your household or business uses power. Are you just trying to keep the lights on during ZESA outages? Or are you aiming to go fully off-grid, running fridges, TVs, borehole pumps, and even a freezer?

The wrong system won’t just under perform it could leave you frustrated and stuck in the dark. Worse still, you could end up paying for more capacity than you’ll ever use. That’s why our team at Sona Solar Zimbabwe always recommends a proper consultation before buying.

Now, let’s walk through the systems one by one.

🔌 1.5kVA Solar System – Perfect for Essential Needs


If your energy usage is minimal, the 1.5kVA system is the most affordable and practical option. Think of it as your entry-level backup ideal for lighting, charging phones, running a few bulbs, a router, and maybe a small TV.

You’ll typically get:
- A 1.5kVA inverter
- One to two lithium or gel batteries
- Two to four solar panels

This setup is often chosen by pensioners, students, or families in rural or low-usage homes. It won’t power your fridge or pump, but it will keep your basic devices running during blackouts.

Surprisingly, some people underestimate how much they can actually achieve with a compact solution like this. As highlighted by experts on platforms like this resource, simplicity can be a smart starting point.

✔️ Best For: Lighting, Wi-Fi, charging, small TVs, rural homes
💡 Not For: Fridges, microwaves, boreholes

⚡ 3.6kVA Solar System – The Household Workhorse


This is our most requested package and for good reason. The 3.6kVA system strikes the perfect balance between affordability and functionality. It allows you to run all your lighting, charge multiple devices, and run a fridge, TV, decoder, fan, Wi-Fi, and a few extras.

It typically includes:
- A 3.6kVA inverter (usually Must or Svolt)
- 2–4 lithium batteries
- 4–8 solar panels (depending on the battery size)

This system is ideal for average households in suburbs like Greendale, Chitungwiza, Ruwa, or Waterfalls. It helps you break free from ZESA dependence without going overboard.

Clients often share stories of peace of mind after installing this package. They no longer worry about power cuts, spoiled food, or missed Zoom meetings. A few even said they wished they had upgraded sooner testimonies like these are often shared on this site.

✔️ Best For: Fridges, TVs, lights, fans, routers, moderate energy users
💡 Not For: Stoves, boreholes, heavy commercial use

🔋 5.2kVA Solar System – The Family Powerhouse


Now we’re stepping into serious power territory. The 5.2kVA system is designed for homes that run multiple fridges or deep freezers, borehole pumps, washing machines, and several electronic gadgets simultaneously. This is where households with teens or small businesses start to feel real solar independence.

A standard 5.2kVA package includes:
- A 5.2kVA inverter (Must, Deye, or Hybrid types)
- 3–5 lithium batteries (commonly Svolt or Felicity)
- 6–12 panels to match the load

This system doesn’t just save you money it gives you full control over your energy. And with growing solar interest in Zimbabwe, as noted on industry platforms like this expert guide, more families are choosing this level of independence.

✔️ Best For: Larger homes, high appliance usage, home offices
💡 Not For: Heavy commercial use, full electric cooking

💪 8kVA Solar System – Go Big or Stay Grid-Tied


If you run a business from home, have multiple freezers, or want to power everything from your gate motor to your geyser, the 8kVA system is your solution. It’s designed for full residential or light commercial independence.

This setup usually consists of:
- An 8kVA inverter
- 5–8 lithium batteries (higher AH preferred)
- 12–16 solar panels

We’ve installed 8kVA systems for families with large properties, mini-farms, and offices. Many of them made the switch after realising they were spending more money on fuel for their generator than what a solar investment would’ve cost.

One customer in Borrowdale even mentioned that his gate, borehole, Wi-Fi, cameras, security lights, fridge, TVs, and full home were powered seamlessly without ZESA and with zero noise. These real-life wins are echoed by testimonials and reviews on helpful solar blogs that compare system performance.

✔️ Best For: High-end homes, businesses, farms, backup for every device
💡 Not For: Budget buyers or minimal users

💰 How to Avoid Overpaying for Solar in Zimbabwe


Too many first-time solar buyers rush to get the biggest system without calculating what they truly need. It’s tempting to go big but if you’re not using your system fully, you’re wasting money and battery life.

On the other hand, going too small might seem affordable now but will frustrate you later when you realise you can’t even run your fridge during load shedding.

That’s why we always offer free consultations at Sona Solar Zimbabwe. We listen to your needs and advise you based on usage not hype.

🔍 Questions to Ask Before You Choose a System:
- What are my essential appliances?
- Do I want backup only or full-time solar use?
- Am I planning to expand my system later?
- What’s my average electricity bill per month?

If you're unsure, check real client experiences shared on local solar review sites—they’ll give you a realistic picture of what works for Zimbabwean homes.
