Selecting the top 10 solar companies in South Africa was a careful and thoughtful process. We wanted to highlight companies that stand out in the industry in size, quality, reliability, and customer satisfaction. Here’s a breakdown of the key factors we considered:

| I’m so glad I decided to use GreenHouse Solar. In order to quote you accurately, you will be asked to send them all your electricity bills for the past 6 months or a year. After that you get an extremely detailed proposal that is highly accurate, no false promises. The quote lists every part of the system, even down to connectors and trunking, so you know exactly what you are paying for. Their actual installation is incredibly neat and of the highest standard. I cannot fault them in any area. Even their communication is top level. We could not be happier. Best service you’ll ever find.  | The service we experienced with Green House was excellent. The planning info was open and clear with almost up to the minute updates. The product is the best on market, the installation people and the quality of workmanship was impressive. All happy and on time, well priced for the quality product and service. I would recommend Green House to any persons looking at any upgrades or new systems. |

| What an efficient and friendly bunch. I ordered two panels online on Friday night. Spoke to Vic on Monday morning and the order was already being processed. I have just received them in perfect condition. Took one day for delivery. I asked Vic to quote me for mounting hardware and his associate Olona sent it to me within the hour. This is super service and I recommend anyone looking for solar systems to deal with Solar Lane. Keep up the excellent service. One more thing, prices are pretty good as well. 😀 | I’ve worked with many suppliers in the solar industry, but Hunter @Solar lane stands out. Their consistency, professionalism, and genuine commitment to quality service make them a top-tier partner. Deliveries are always on time, communication is clear, and they go the extra mile to make sure we have what we need to succeed on our projects. It’s rare to find a supplier who combines reliability with a personal touch—Hunter does just that. Highly recommend! |

| Green Way is the only way to go! They came highly recommended to me and have now just completed a second job at my home. Richard was extremely adept at putting together a solar system to meet my unique needs. Technicians and contractors were punctual, professional, friendly and skilled. I was kept in the loop from commencement to completion of the job, and follow-up service was equally gratifying. History and experience are essential in this industry. Go Green Way! | Greenway Solar was recommended by my colleague, who was very happy with their services. I gave them a short, and after completing an online form, I was contacted by Patience Sibanda, who was friendly and ready to help. She collected my power requirements. The design tech team contacted me in a couple of days with the design and made an appointment for a site visit. Very professional and punctual.The installation team was very professional, clean, and punctual. The post installation handover and customer education was impressive for the person who didn’t know much about the Solar system. Well done to Richard and team for the job well done! Looking forward to the excellent after installation customer services |

| I had an excellent experience with Humerah at Artsolar. Their delivery of my solar panels was prompt and arrived before the promised time. Humerah was friendly and professional, ensuring all went smoothly. Highly Recommend Artsolar for anyone looking for reliable and fast service. | Introduced via Investec and very happy with the outcome. Sales department is always quick to respond and pricing competitive. Artsolar will send their team to you regardless of whether they have an office in your province or not. A key point is that Artsolar is the only SA manufacturer of solar panels and provides a 30 year warranty on these – they therefore know solar. The installation team was very professional and informative with a quick turnaround time. Happy to recommend their services. |

| Had a great experience with Sinetech and will definitely use them again. I asked about when they were expecting stock of an item that was listed as backlog order and they responded quickly via email and even gave me an ETA. When I finally placed my order, the product arrived in under 48 hours, and it’s great quality. I ordered a Ratel 8100 UPS, and it was exactly what I needed to run my 19v Asus router during load-shedding. | I have a Victron Energy UPS with 12 Omnipower OPR 120Ah 12 V batteries supplied and installed by Sinetech in March 2020. The batteries failed in early February 2021. I made a warranty claim against Sinetech, and after testing the batteries, the claim was approved, and new batteries were installed on 12 March, after a delay of a couple of weeks due to no stock. |

| My inverter got damaged by lightning, and I took it in for repairs at Segen in Northlands. I was greeted very friendly at the reception and promptly directed to the returns department. Here, I was greeted by Yvonne, the returning assistant. She called Khuthadzo, the technician who quickly assisted me. It looks like it is just the control module that is faulty, and they had to book the unit for repairs. I have to thank Yvonne and Khuthadzo for their friendly and professional service. I will definitely do business with Segen again. | Excellent customer service, big props to the head of Customer Experience. I am not even a direct customer, and I was still assisted. Thank you for sorting out my issue! |

| One Energy supplied and installed our Solar system. Adrian did an excellent job installing AlphaESS Solar on my house! The workers were prompt and professional. The work was done very well and blends perfectly with my roof. Everything has been working great, and they are very good at responding to questions. Job well done. | One Energy is a pleasure to work with. We did a lot of research in selecting the installers of our PV Solar system. Adrian was the only person that first did a site visit before providing a quote. None of these generic quotations that the industry is renowned for. He also provided great insight and advice. They only use quality products and components. It has been smooth sailing right from the start. They kept us informed at all times. They are professional and very punctual. They even installed the system ahead of the scheduled installation date. Our system has been running without a glitch, and we cannot be happier. I can highly recommend One Energy Cape Town for your PV Solar system needs. |
