How Much Roof Space Do You Really Need for Solar?
One of the biggest questions homeowners ask before installing solar in Zimbabwe is simple: “Do I even have enough roof space?” It’s a fair concern, especially with different roofing styles and the growing demand for solar power. What many people don’t realise is that even a small section of your roof can generate a surprising amount of power when fitted with the right panels. At Sona Solar Zimbabwe, we have seen clients with modest homes achieve complete energy independence simply by using high-efficiency panels that maximise every square metre.

Understanding Solar Panel Sizes
Most solar panels used in Zimbabwe range between 1.6m to 2.2m in height and just over a metre in width. This means each panel typically requires about 1.7 to 2.3 square metres of roof space. When you think about a 5kva system, which is a popular choice for families, you’ll need between 8 to 110 panels depending on the brand. That translates to roughly 30 to 40 square metres of usable roof area. Many customers assume they don’t have enough space, but after an assessment from experts like local specialists, they realise their rooftops can actually fit far more than expected.
Factors That Influence Roof Space
Not every roof is the same, and that makes calculations unique to each household. The slope of your roof, the direction it faces, and even nearby trees can influence how many panels you can install. In Harare, for example, north-facing roofs capture the most sun throughout the year. Even if you don’t have a perfect roof, modern mounting systems allow panels to be placed creatively for maximum sunlight exposure. That’s why professional evaluations from trusted installers like recommended companies are essential—they’ll tell you exactly how much power your roof can produce.
High-Efficiency Panels Save Space
One of the game changers in 2025 is the availability of high-efficiency panels like Longi and Aiko, which generate more power in less space. This means you don’t need a massive rooftop to run your home. For example, a 10-panel system of high-output panels can often match the energy of 14 standard panels. This is a huge advantage for urban homeowners with limited roof sizes. Clients who come to leading installers often discover that they need fewer panels than they initially feared.
Real Examples from Zimbabwean Homes
At Sona Solar Zimbabwe, we recently helped a family in Borrowdale with just 35m² of roof space install a system that powers their entire home—including air conditioning, a fridge, and entertainment systems. Another customer in Budiriro managed to run a full borehole pump and lighting system with just 20m² of space. These stories prove that even when you think your roof is too small, the right combination of panels, inverters, and batteries can completely change the outcome. That’s why a consultation with our team can make all the difference.
What If You Still Don’t Have Enough Space?
For homes with extremely limited roof space, there are always alternatives. Ground-mounted solar systems can be installed in your yard or garden, while solar carports double as shade for vehicles and energy generators. Businesses across Harare are already embracing these smart alternatives. And with battery solutions like Svolt and Evolt, you can store every unit of energy for night-time use, making your system even more reliable. By working with experts who understand Zimbabwe’s energy challenges, such as trusted advisors, you’ll always find a solution that fits your needs.
Final Thoughts
The idea that you need a huge roof for solar is one of the biggest myths holding Zimbabweans back. The truth is, even small homes can achieve complete energy independence with the right design and technology. Whether you live in a city flat or a suburban house, there’s a solar solution for you. At the end of the day, it’s not about how much space you have—it’s about how smartly you use it.
