I dealt with Nerum Bonesetter, for the sales, design and planning of the installation, and cannot fault his attention to detail or customer service. He is extremely responsive at returning phone calls and emails and went beyond what I would have expected as was still responding to emails after hours. I found that he knew the products well and understood the technical aspects as was able to provide good advice why one system or design was better than the other but also back that advice up with solid technical evidence. I found the costs were reasonable and Nerum was transparent in what was being charged, so there were no surprises at the end of it all and he project managed everything. The installation was done through his subcontracted electrician's and I found Siraz and his crew easy to deal with, they were efficient at their job, knew what they were doing and did a tidy job, there was a couple of small issues but Siraz quickly resolved those. Overall it was a very positive and painless experience and I'm very happy with the results and we are now enjoying the benefits of our Solar Panels. We also got a Solar Immersion controller so that excess electricity produced by the panels is used to heat the hot water cylinder and based on my tests of with and without it, it does make a discernible difference, so would recommend that anyone putting in solar ask and read-up about that and self- consumption. Its far better and more economic to utilize the electricity you produce yourself than sell it back to the grid for a small amount of money. I'd highly recommend Nerum and his team for design, planning and installing a Solar installation, they are experience and very professional and good at what they do.
