Solar System Price: An All-In-One Conspectus

How Much Does a Solar System Cost?

The cost of a solar system in South Africa can vary significantly depending on various factors, including the size and type of system, installation, available incentives, and so on. Generally, the average cost of a home solar system can vary between R60,000.00 to R250,000.00 or more. Here we give a breakdown of estimated solar power systems South Africa prices according to wattage.
3kW Solar System Price in South Africa: Typically, between R30,000.00-R70,000.00.
5kW Solar System Price in South Africa: It can cost anywhere between R70,000.00 to R140,000.00.
8kW Solar System Price in South Africa: It is something between R140,000.00 to R200,000.00.
10kW solar system price South Africa or above: Above R200,000.00 due to the large number of panels involved and the sheer workload of installation.

Types of Solar Power Systems and Their Price Range

Solar power systems come in primarily 3 types: grid-tied, off-grid, and hybrid, each with its own features and varied prices. We’ll expound on them below.

Grid-Tied Solar Power Systems

Grid-tied systems are the most common and cost-effective solar power solution. These systems are directly connected to the local electrical grid. With such systems, any excess power generated during the day is fed back into the grid, and you may receive credits for this excess power through net metering programs, offsetting some of your energy costs.

The price range for grid-tied systems in South Africa typically varies from R30,000.00 to R300,000.00, depending on the system size and quality of components.

Off-Grid Solar Power Systems

Off-grid solar systems are also pretty common, though less prevalent than grid-tied ones. These systems are totally disconnected from the power grid and rely on solar power to generate electricity alone. After energy is generated, it is then stored in batteries for use during the night or on cloudy days when solar production is low.

Compared to grid-tied solar systems, off-grid systems are more expensive due to the cost of batteries and additional components required for energy storage. Specifically speaking, off-grid solar systems need a general cost of R150,000.00 and R350,000.00 or more

Hybrid Solar Power Systems

Hybrid systems combine the features of both grid-tied and off-grid systems. They can operate connected to the grid but also have battery storage for backup power. These systems generate power during the day and store the generated power in the battery. During cloudy days or power outages, the stored power can be used to power home appliances. On the other hand, if there is excess energy left in the battery, it can be directed back into the power grid like grid-tied systems.

Due to its hybrid nature, the cost of hybrid solar systems is generally lower than that of off-grid systems and a bit higher than that of grid-tied solar systems.

Factors That Influence Solar System Price

Generally, solar power system prices in South Africa are influenced by many factors. Let’s see them in detail.
System Size: The capacity of the solar system, measured in kilowatts (kW), has a significant impact on the price. Larger systems usually cost more. For example, the 20 kW solar system price South Africa will be reasonably higher than the 3 kVA solar system price and 10 kVA solar system price.
System Types: Off-grid systems with energy storage are usually more expensive than grid-tied and hybrid setups.
Inverter: Inverters are essential for converting the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity usable in homes or businesses. The type and quality of inverters, such as string inverters, microinverters, or power optimizers, can impact the cost.
Installation Complexity: The ease or difficulty of the installation can influence the price. Factors like roof type (flat, sloped, tile, asphalt shingle), shading, and local regulations can affect installation costs.

How to Choose the Right Size Solar System for Your Budget?

Choosing the right size solar system for your budget is a crucial decision when considering a solar installation. Here's a step-by-step guide to help you determine the appropriate system size that aligns with your financial resources:
Assess Your Energy Needs: Review your electricity bills to determine how much electricity your household or business typically uses in kilowatt-hours (kWh) over a year.
Determine the offset: Determine how much energy you aim to offset with your solar system according to your budget.
Calculate Your Solar Potential: Investigate factors such as your geographical location, available sunlight, shading, and local climate to determine how efficient the solar system will be.
Determine the number of solar panels: Calculate the number of solar panels needed based on your energy need and the solar potential of the installation location.


In conclusion, understanding the price of a solar system is a critical step in making the transition to clean, renewable energy. While the initial investment may seem daunting, the long-term benefits, both in terms of financial savings and environmental impact, make it a worthwhile endeavor. By learning about the general solar system prices and different factors affecting the cost, you are better informed to proceed with your solar journey, cut your utility bill, and contribute to a greener future for the globe.


How Much Is a 5000-Watt Solar System?

The cost of a 5000-watt (5 kW) solar system in South Africa can vary depending on several factors, including the type and quality of solar panels, installation location, and so on. The general estimated 5 kVA solar system price range is R70,000.00-R140,000.00, with the exact figure depending on factors like system types, installation costs, and so on.

What Can a 10kW Solar System Run in South Africa?

A 10 kW Solar System can run a range of home appliances like lights, televisions, laptops, refrigerators, and even air conditioning. In fact, a 10 kW Solar System can generate 40-50 kWh of power each day in South Africa, which is typically enough to power two small families or one large family.

How Many Batteries Does a 5kW Solar System Take?

The number of batteries a 5 kW solar system needs depends on factors like your system type, nighttime energy consumption, the capacity of a single battery, and so on. Generally speaking, you need to have at least 500Ah of capacity for the 12V battery to cover your nighttime energy needs. This implies that, for instance, you’ll need 2 batteries in your system if each battery is 250Ah and 12V.
