Sungain sales was not pushy but helpful in explaining different options and configurations. They went to great lengths and willing to ensure I got what I requested. To get my business, they offered a discount to my initial quote. On the day of the installation, the contractors arrived on time and discovered they weren’t able to install the panel in the configuration as discussed. However after some discussion, we came to a mutually agreeable outcome. This was exceptional customer service on their part. The workmanship was performed to a high standard – they were honest to advise of a few cracked tiles which they replaced or sealed up. No leaks were discovered after the recent rain. Happy I was producing solar power that afternoon.
