So, how much does it cost to install a 100kW solar system? Well, the cost of installing a 100kW solar system in South Africa varies depending on the installation location and the components used. As of 2024, the average cost for such a setup is approximately R1.5 million to R3.5 million. This cost includes the solar panels, inverters, mounts, cables, and other necessary equipment.

It is important to consider additional expenses such as permits and inspections, which can increase the overall cost. However, the price of installing these systems has been decreasing over time, making solar power an attractive option for businesses. Typically, businesses can expect to recoup their investment in about 3 to 5 years, with internal rates of return often ranging between 20% and 30%. When evaluating the investment, it is essential to consider the total system cost, your current electricity bill, financing options, and potential earnings from feeding surplus energy back into the grid.

Factors affecting solar system installation costs

Many elements determine the cost of installing a solar system. Understanding what these are helps us grasp the expenses. Let’s dive into each key factor:

Solar panel prices

The initial expense is typically the solar panels’ price. This can change based on efficiency, brand, and quality.

Inverter prices

Solar inverters convert DC energy from panels into usable AC energy. Their prices alter with capacity, tech, and efficiency.

Mounting equipment costs

Mounting gear is essential for panel attachment. Factors affecting their price include roof type, installation difficulty, and mounting design.

Cabling and electrical component costs

Wiring and connectors link panels, inverters, and components together. Costs vary with wiring length and complexity.

Battery storage costs

Battery storage offers backup and peak-demand energy use. Its cost depends on the technology and storage capacity you pick.

Installation labour costs

Installing the system incurs a significant labour cost. The installation’s difficulty, roof type, and system size impact this cost.

Consultation and design fees

These fees pay for installers’ assessment and system design to meet your energy needs. They vary with project complexity and installer expertise.

Additional fees

Don’t forget local permit and inspection fees. They vary by location and add to the overall cost.

Remember, you should also budget for maintenance and repairs. Solar panels generally need little maintenance but may require repairs and part replacements over time.

For the best deal, get quotes from multiple qualified installers. This permits a thorough comparison of prices, expertise, and satisfaction levels before choosing.

Financing options for solar system installations

Financing can turn a solar system dream into a reality for many homeowners in South Africa. One way is through home loan financing. This method lets you add the solar installation cost to your existing mortgage. Thus, you can pay it off over a longer period.

Rent-to-own financing is another path to consider. Here, homeowners make monthly payments towards the system’s cost. Eventually, they own the solar equipment. It’s ideal for those not ready for a big upfront payment but still wish to go solar.

A third, increasingly favoured option is subscription service financing, provided by solar companies. Here, homeowners pay a set monthly fee for solar power. This fee includes not just the use of the system but also its upkeep. It’s a way to reap the benefits of solar energy without having to worry about the purchase price.

If extra financial help is needed, bond originators can aid in finding the right financing. South African banks like FNB, Standard Bank, and Nedbank are well known for their tailored solar financing services.

When reviewing the costs of installing a solar system, one must weigh energy use, system needs, and financing conditions. Although the initial cost might be higher than traditional electricity bills, solar solutions offer the chance for self-sufficiency and savings in the long run. Homeowners can pick from many financing options to match their financial plan and needs.
