Warranty Replacement Delay – Pylontech UP5000 Battery
On 5 January, I reported to GC Solar that my Pylontech UP5000 battery suddenly discharged 50% of its stored energy at 05:20 in the morning without any load connected to the system. After I followed up, GC Solar instructed me to deliver the battery to their Midrand office for inspection, which I did on 9 January. On 14 January, I was informed that the battery had been found to be faulty and would be replaced under warranty. At that stage, I was told replacement stock was not available. At the end of January, I was informed that stock would arrive and that I would be first in line to receive my replacement battery. However, after contacting the Midrand office again, I was told that stock will now only be available at the end of February. I have now been without my battery for more than a month and a half. Customers invest in backup systems for reliability and peace of mind, especially in South Africa where power stability is a major concern. This level of after-sales service is unacceptable. At this stage, I cannot recommend purchasing a Pylontech battery - they don't have stock. Trust is critical when investing in backup power. Customers should not have to question whether they must rely on Eskom or on their own system — especially when that system depends on proper after-sales / warranty support.

G C Solar
On the 15/01/2025 I bought an item from GC Solar, received item in good condition but I some how misplaced my Tax invoice. On 05/02/2026 I contacted G C Solar and asked them if they could help me to get a copy of invoice, I only had my old email address and serial number to help G C Solar find invoice from the system that has since been changed. I give a 5 star rating to Claudia Borcea for making the effort to find my invoice and in no time Claudia phoned me to say she got it and sent of to me by mail. I thank G C Solar and specifically Claudia for helping me to obtain invoice. Good work and customer care

Angry GC Solar client
Do not make use of this company. They installed a solar system in my house in Marloth park more than a year ago. It has been sending power back into the grid resulting in tripping the prepaid meter. I have spoken to many technicians including Romarno about this issue. Unanswered whatsapps and phonecalls. They have made false promises and is incapable of.solving problems with their own systems. I would not recommend dealing with them at all.

Do not buy from GC Solar! Fair warning
TL:DR 2 years later and my faulty system is still not fixed. An absolute horror story having purchased from GC Solar. 9 months into having their Growcol brand installed in my home and the faults started. Naturally the warranty claim began and my system was taken in for a repair which took weeks and only finally got looked at after I called them looking for an update (warranty was handled via the installer), magically the system available to collect the same day as my phone call. This where the first ***** dealing happened with the previous head of repairs, Lukas, replaced the mainboard and had my system reinstalled. It came out later that the mainboard had never actually been replaced and that it was ****d to buy time which lead to more faults (obviously). The new head of repairs, Romarno, came for an inspection and took in my unit for testing, claimed to have changed the mainboard this time (How can I even be sure since they have played me once already). The system has faulted 7 times since being reinstalled (mainboard replaced? lol). After months of back and forth, another visit from GC and 0 action I decided to begin finalising this discussion and take legal action, all I needed was a report saying its the installation or that its the inverter so I can put one of the parties names on the legal documents of who is "getting it". It took Romarno a month of telling me that he had sent the report to my installer and my installer saying that he is telling them another story. I eventually go the report saying that there is nothing wrong with the system and that it is 100% operational. I have never been so angry in my life! So... 7 faults, 4 site visits from suppler, ~8 from installer hundreds of emails, phone calls and 2 YEARS! later I am still staring at this stupid P.o.S on my wall. It will, on average, weeks to get a response. Disgusting company and horrible service. DO NOT BUY FROM GC SOLAR! DO NOT BUY GROWCOL. Use suppliers like Mustek or Rectron if you have the option to.

Avoid Pylontech batteries and GC Solar products at all cost.
Sent my batteries in for repairs. Waited 5 weeks. On the 10th of January 2025, I booked my batteries in for repairs. After 1 week, I phoned them to find out what was going on. I was told that the technician that "worked" on my battery wasn't in and that they would call me back. They didn't call me back. I called the next day, only to be told that the contact person "Just came out of a meeting" and she will go and find out. Waited another 2 to 3 hours and called her back again. I was then told that they were still waiting for the report from China. After another week, I called only to be told that the contact person was in a meeting and would call me back, which she didn't. I called and was told that they were still waiting for China. By week 4, I was told that they delay is because of Chinese new year, even though my batteries had been with them from the 10 of January. By week 5 I finally got told that the warranty won't cover the costs, because "there were short circuits on the battery". Now as an end consumer how would you disprove this, you can't really. I was told to pay quite a hefty amount to replace the BMS on both batteries, paid it and eventually got the batteries back after 5 weeks. They constantly blame shift, are always in meetings and everyone else is to blame for their bad services. The major problem was that this is the sole importer of the Pylontech batteries, and they are giving Pylontech a bad reputation.

Most unprofessional service from GJ
Worst services received from GJ over the phone doesn't have any communication skills. He doesn't give messages to sales staff as per our request. He dispatched wrong stock and I had to drive back from site as he doesn't know the products he is selling costing me extra to fix his mistakes. He is extremely rude and arrogant.

Complaint Regarding Tswane's Behavior and Commendation for Romano Johnson
Dear GC Solar, I am writing to express my extreme disappointment with the conduct of your employee, Tswane. Their behavior towards me has been consistently rude, disrespectful, and unprofessional. Their lack of empathy and customer service skills has made this entire experience incredibly frustrating. In stark contrast, I would like to commend Romano Johnson, Head of Department, for their exceptional assistance and prompt action in resolving the issues I encountered. Their professionalism, understanding, and dedication to customer satisfaction were truly commendable. Romano's positive attitude and efficient problem-solving skills have significantly improved my overall experience with GC Solar. I believe that employees like Romano should be recognized and rewarded for their outstanding work. Moving forward, I will only engage with Romano for any future interactions with GC Solar. I urge you to take immediate action to address the behavior of Tswane. Such conduct is unacceptable and detrimental to your company's reputation. I look forward to a prompt and satisfactory resolution to this matter. Sincerely, Anne
