How to Select the Best Solar Power Installers in South Africa

South Africa’s abundant sunlight and the rising cost of electricity have made solar power an attractive and sustainable solution for many homeowners and businesses. However, choosing the right solar power installer is crucial to ensure a successful and efficient solar installation.

With numerous companies offering solar installation services in South Africa, it’s important to consider several factors before making your decision. In this article, we will guide you through the process of selecting the perfect solar power installer in South Africa.

 1. Research and Reputation

Start by conducting thorough research on various solar power installers in South Africa. Look for companies with a strong reputation and positive customer reviews. Check their experience in the industry and the number of solar installations they have completed. A reputable installer will have a track record of successful projects and satisfied customers. Ask for a reference or two you can talk to. Look for Google Reviews.

2. Certification and Accreditation

Ensure that the solar power installer you choose is properly certified and accredited. In South Africa, the South African Photovoltaic Industry Association (SAPVIA) and the South African Renewable Energy Council (SAREC) provide certifications and accreditations to reputable solar installers. These certifications indicate that the installer meets industry standards and has the necessary expertise to handle solar installations.

Make sure your installer is certified to issue a PV GreenCard after your installation. Only installers who have received certification from SAPVIA have the authority to issue the PV GreenCard for your new solar power installation.

A PV GreenCard serves as a comprehensive report that installation professionals complete upon finalizing the setup process and transferring the finished product to you – the home or business owner. It provides an in-depth breakdown of the system, including the specific panels and inverters utilized, the system’s capacity, the installation process, and testing details, along with additional valuable information.

3. Expertise and Experience

Consider the expertise and experience of the solar power installer. A skilled and experienced installer will have in-depth knowledge of solar technology, system design, and installation processes. They should be able to provide customized solutions based on your energy needs and site requirements.

Ask for examples of their previous installations and inquire about their experience working with different types of solar panels and inverters.

 4. Product Quality and Warranties

Check the quality of the solar panels, inverters, and other components used by the installer. High-quality products ensure the longevity and efficiency of your solar system.

With a wide range of solar products being imported into South Africa some of them are not ideal for long-term ROI.

Do your research, and enquire about the warranties offered by both the installer and the manufacturers of the equipment. A reliable installer will provide comprehensive warranties that cover the performance and durability of the system.

5. Site Assessment and System Design

A reputable solar power installer will conduct a thorough site assessment before designing your solar system. They should visit your property to evaluate factors such as roof orientation, morning and afternoon shading, and available space.

This assessment will help them design a system that maximizes energy production and meets your specific requirements. Ask the installer about their design process and if they provide detailed system layouts and energy production estimates.

6. Installation Timeline and Project Management

Discuss the installation timeline with the solar power installer. A professional installer should be able to provide a clear timeline from the initial consultation to the final installation. Inquire about their project management approach and how they ensure efficient and timely completion of the installation. Clear communication and transparency in project management are essential for a smooth and successful installation process.

7. Cost and Financing Options

Obtain detailed cost estimates from multiple installers and compare them. While cost is an important consideration, it should not be the sole determining factor. Consider the overall value you receive in terms of product quality, warranties, and the installer’s expertise.

Additionally, inquire about financing options, rent to own, Solar as a Service, or potential tax incentives available to help offset the initial investment.

8. Customer Support and After-Sales Service

Consider the level of customer support and after-sales service provided by the solar power installer. A reputable installer will offer ongoing support, system monitoring, and maintenance services to ensure the long-term performance of your solar system. Inquire about their response time for repairs and any additional services they offer.


Selecting the perfect solar power installer in South Africa is a crucial step towards a successful solar installation. Thorough research, and consideration of reputation, certification, expertise, and product quality will help you make an informed decision. Take the time to assess multiple
