What is the most critical step when buying a solar system?

The most critical step is professional system sizing. A 'one-size-fits-all' approach is a catastrophic error. The process must begin with a comprehensive load assessment to understand your specific energy needs.

How are the main components of a solar system sized?

Each component is sized differently. The inverter (kVA/kW) is sized based on your peak load (appliances running simultaneously). The battery bank (kWh/Ah) is sized based on your desired runtime or endurance. The solar panels (Watts) are sized based on your daily energy consumption and the need to recharge the batteries.

Why "One-Size-Fits-All" Solar is a Costly Myth

At Sona Solar Zimbabwe, our work is to build systems that deliver high performance and a guaranteed return on investment. In the rush to achieve energy independence, many are falling victim to a dangerous misconception: the idea that a generic solar package is a viable solution. This is a catastrophic strategic error.

The Dangers of Improper Sizing

This is the most common mistake. An undersized system will constantly trip, fail to power your essential appliances during load shedding, and cause your batteries to drain too quickly. This leads to premature battery failure and the need for a costly replacement, creating a cycle of frustration and financial loss.

While less common, this is equally problematic. You will have paid a premium for capacity you will never use, resulting in a poor Return on Investment. It’s the equivalent of buying a haulage truck to do your daily grocery run—inefficient and wasteful.

Our Process: It Starts With Your Loads

We are your premier choice for a reason. Our philosophy is built on a foundational truth: there is no one-size-fits-all in solar. We begin every consultation with a comprehensive Load Assessment, asking about the specific appliances you intend to run, their wattage, and for how long. This allows us to build a system that is not just a product, but a tailor-made solution for your lifestyle or business.

Decoding the Components

The size of your inverter (kVA/kW) is determined by your peak load – how many appliances you want to run simultaneously. For basic needs, an entry-level 1.5kVA system may suffice. A standard home may need a mid-range system like the 3.6kVA combo, often considered the ultimate setup. Large homes or businesses require high-capacity inverters (5kVA - 11kVA).

The size of your battery bank (kWh/Ah) is determined by your runtime – how long you need power when there's no sun or grid. A small system might use a single 12.8V battery, while a 5kVA or larger system demands a robust 48V battery bank, often with multiple batteries for extended endurance.

The number of solar panels you need is determined by your daily energy consumption and the need to fully recharge your battery bank each day. More panels mean more free energy to power your daytime loads and store for the night, ensuring true energy independence.

Frequently Asked Questions

A load assessment is the professional process of identifying every appliance you wish to power, its wattage, and how long you need it to run. This crucial first step is the foundation for designing a solar system that is perfectly tailored to your needs, preventing issues like system tripping or premature battery failure.

Every home and business has a unique energy consumption profile. A generic package is not designed for your specific loads and will almost certainly be either too small (leading to system failure) or too large (a waste of money). Only a custom-sized system can guarantee reliable performance and a good return on investment.
