OTI Power Pty Ltd Solar Reviews

Good design and Install

Professional, prompt service and quote process, but need to do plenty of research to ensure you get what you want when discussing requirements with representative.
Installation very good quality an no out of pocket costs. We wanted a high end quality system of 10KW with 3 phase power with possible future connection to a battery, and that's what we received.
Customer service and grid connection follow up very good. They will be doing a full review after first quarterly bill to recommend which plan and electricity vendor to migrate to, if required.

Highly Recommend

“OTI Power has been amazing to deal with for our solar installation. OTI Power worked with our builder to get as much as the cabling installed during construction and once we were ready they installed our solar system so efficiently. The install team were very helpful and set the monitoring system up for me before they left my home, no hassles at all. OTI Power not only delivered what they promised, they had unbeatable pricing, exceptional customer service and a friendly helpful install team. The follow up after installation to ensure we were with the correct/best energy supplier to best maximise our investment was also another great service. I would highly recommend OTI Power”.

Informative and straight forward during quote process and great trades on installation.

Informative and straight forward no high pressure selling.

The guys doing the installation did clean tidy work and replaced some of our cracked roof tiles at no extra cost. ( We suppled the tiles)

Customer service was great overall.

I appreciate all the information you provided me. I used it to make comparisons between the range of products and services offered by two of your recommended suppliers and two others I researched about. The knowledge on your website gave me confidence in making the right decision, which was not just based on price. Show additional information
Peter McLaren and his team have been nothing short of exceptional with communication and service! He even helped me move to a more suitable retailer with a direct contact. I am very happy so far. We will now have to wait and see what having solar really means to our power bill after using it for at least a quarter. Expecting to get connected to the grid in the next 15 days.

Fantastic Installation

Right from the get go I was impressed with OTI. Harrison was outstanding, he knew his trade, he communicated, he listened, and frankly I was not surprised at the outcome. Installation went very well, they were on time, tidy and clearly capable. Jess led the install, genuine good guy who pointed out some other considerations with some potential issues with our electrical board to think about. Harrison took time in the set up of the applications and the consultation around the selection of our system. He also organized the grid connection and made some extra calls around feed in tariffs. It would be fair to say I am a hard marker, wouldn't hesitate in recommending OTI. Show additional information
I am very pleased with all aspects of the process to date and happy to recommend Grant and OTi. Show additional information
Very impressed with the installers. Did a great job and cleaned up after.
Very professional. Couldn't be happier.

Awesome end-to-end experience with OTI and Harrison!

Harrison was personable and a pleasure to deal with throughout the end-to-end process - From quotation, installation, and post-installation handover! He was always responsive and even spent time to run through the online/mobile app and how the solution worked. We are over the moon to have finally cutover to solar, and it coudn't have happened without Harrison and the OTI Team. Cheers! Show additional information
The salesman Grant was very great to deal with and I would recommend him to anyone looking to get solar installed.
The Installation team that did the job were also very good and did a great job on the installation.
As for Finn at Solar Quotes well what can I say, the information that you supplied was very helpful and made my decision a lot easier.
The information on Inverters and Solar Panels that was on your website was very helpful.
Thanks to you and your team for all your help

Local company, great service

Incredible service from Harrison. OTI was very patient when there were the inevitable delays on our side but when the time finally came, the installation was swift and hassle free. Now we are enjoying free electricity even though it’s winter! Show additional information

Well done Harrison. I have recommended you to others

Harrison came at a time to suit us and on time. Really good and patient in answering questions and giving expert technical advice and explaining the issues. No hard sell. Also, the best of 3 quotes. Installation turnaround time was much shorter than expected. The Installer (Jesse) was also on time, polite and proficient - no mess. After sales service good too - quick response time to questions and providing on-going advice to maximise the benefits. Happy to recommend. Show additional information
Another company who was more positive about the solar analytics system actually quoted a little lower (slightly less efficient solar panels), but in the end I went with the company whose sales man convinced me that they would take care of me and who made a big song and dance about after-sales care. They nearly lost the sale because they are very unenthusiastic about the value of solar analytics, viewing it as an expensive waste of time and money. However, having been assured that any competent electrician can install the monitoring widget, I think/hope that their dismissive attitude towards it won't lead to a bad installation and I can get what I want from my preferred provider. Fingers crossed. Show additional information

We always get at least two quotes, but where you helped was to get us started on understanding what was available and providing three prequalified supplier/ installers. In the event, we decided to put in the best system we could afford, with longevity a major criteria.

We contacted all three you suggested and two of our quotes were similar but on slightly different systems but the third one never quoted.
OTI’s installers were literally “ fantastic” treating our roof tiles and us with respect.

We went with OTI who were enthusiastic about solar and our location and recommended the individual panel optimisers with our REC panels and SolarEdge inverter.

With 36 panels ( 10.6KW) installed we got over 50 KWH most days until it rained and now we are sitting just under 50 as the days shorten. In summer we expect to do better than 50.

While it’s still early days, we are enthusiastic solar power producers.
Thanks for the service.

Highly Recommend!

Harrison from OTI Power was a pleasure to deal with from start to finish. He organised to come out to see me within a couple of days of my call and I had the quotes sent to me the same day. Any questions I had were answered quickly and honestly. It was a pleasure to deal with a company that really looks after their customers, and operates in such a professional manner both before, during and after the installation.

Our solar was installed a week after we accepted the quote. The team who did the installation were fantastic and were also a pleasure to deal with. Our job had it's challenges but they worked tirelessly to get it done and we couldn't be happier with the quality of their workmanship. They were polite, turned up on time and left the job spotless. I cannot rate OTI Power highly enough and have already recommended them to other people interested in getting solar.

The salesman (Harrison Blake) from OTI power is very helpful, his quick response on text and email is very fast, even during easter holiday. The replies are always honest, simple and quick to understand.

Although the price is not the cheapest one, but i think the system which they offered is very good for value, and best for my home requirements. .

Although, during the installation part of the roof was damaged, but they agreed to fixed for me, so i am very appreciated their workmanship and attitude.

Since the installation, the system is running so far so good, I have no problem recommend OTI Power to anyone..

Top Shelf Service

Firstly I'm not being payed for the following comments.
Harrison from OTI was great to work with. He and his team were professional, on-time with a tidy and clean work area. The system was completed and commissioned in one day.
Thank you Blake and the team from OTI

Extremely pleased with OTI Power and ever so grateful to you for providing the recommendation along with the other companies - I also obtained quotes from them, but was disappointed with them as the only contact was by phone while I was driving and I found it difficult to communicate. Hawking was very keen for the quote to be successful. But the winner for me was OTI as they are very local, Peter is a partner in the business, they could install within 2 weeks and connected to the meter box upon installation so I can see the meter going backwards and follow the activity on the app. I was totally convinced when they didn’t want a deposit or payment until I was satisfied. The day after installation (which all went very smoothly as planned) I had a problem with the app receiving data. Next morning Peter was here to resolve the issue. Amazing post installation customer service. Show additional information
I can not fault OTI Power. Josh from OTI Power was able to offer the best deal I could find for a 16 LG panel installation with Enphase microinverters, and worked with me to be completely accommodating to all of my enquries and my specific installation needs. Communications at every stage were clear and open. The installers were polite and did an excellent job. I can't recommend OTI Power enough. Show additional information
Excellent service during installation. An issue with the set up on the inverter / smart meter that gave incorrect readings on the site was corrected quickly. Show additional information
The only problem I had was we haven't been informed that we have to give the access inside the house to go the manhole. So they had to come next day to finish the job. Also inverter has been installed outside the house not inside the garage since it will cost more to do so. This was got to know the day they came for the installation and not in the quotation. First they recommended to install the inverter inside and then they changed the word saying warranty covers everything. Show additional information
OTI Power provided a great solar experience form start to finish and continue to look after us by keeping me up to date with the best power deals available. Show additional information

I cannot rate OTI Power highly enough, after a year of investigating solar for our business premises and dealing with very sub standard suppliers and inadequate product that was over priced, we came across OTI Power. Their customer service is far superior than any competitor, a system that was scoped correctly from the onset and installed with precision. We immediately can see the benefits and can be monitored from the apps installed on our phones and to know this will pay for itself in just four years is the best business decision we have made. I cannot rate the end to end service solutions enough. We have also gone with OTI Power for our home. Also to be informed we get a 25 year warranty! Show additional information
OTI were by far the most professional company during the quotation process. Peter is genuine and provided advice that suited our applications. In fact we decided on one system for the business and one for our domestic situation. We await the installation and customer service process. Show additional information
Excellent Customer Service from Josh Kwanten. Follow ups to explain Solar Edge APP and website was very beneficial.
Josh provided outstanding information on the solar product and kept us updated on all aspects during the installation.
An "On site Visit" from Josh and Harry before installation of the solar panels was much appreciated.
I would certainly recommend Josh Kwanten - Oti Power Representative to family and friends for Oti solar quotes.

We got 3 quotes and OTI was hands down the most professional and trustworthy. They gave us lots of information and options and their prices were competitive. All the way through the process, their service was outstanding. They got everything organised, turned up on time and over-delivered on every promise. Getting solar installed is a long, complicated process that relies on your power provider. Ours was incredibly slow, but OTI chased them up and were there to advise us every step of the way. Six months later and our $1,000 quarterly power bill is now $200. We couldn't be more satisfied. You can trust these guys - they're great. Show additional information
I would like to thank Peter from OTI power for the great deal on my solar system and great advice and service. Peter made everything so easy. Show additional information
The clincher was that OTI was the only company to site visit before finalising the quote. Show additional information
Hi Finn
Whilst I did not go with one of the suppliers you had contact me, I can say that without your Website and the tremendous amount of quality information it contained, the journey I travelled towards the installation of Solar Power would have taken much longer. After further investigation I have had an 8Kw system installed with LG 335W panels and a Solaredge 8Kw Inverter and Optimisers. I apologise for not getting back to you sooner

The team at OTI Power were fantastic. As someone who has been looking at getting solar panels for the past 5 years we were thrilled with their expertise, service and quick installation. They also know what they are doing (which is great given all the questionable solar businesses with ignorant call centre sales people that are promoting cheap solar panel systems that are rubbish). I would highly recommend Blake and the OTI Power team. Show additional information
Hamish from Oti Power was very informative, efficient and pleasant to deal with. The material he supplied helped us understand why Oti Power were recommending the particular panels and other components for our house and needs. This made it easier for us to compare the quotes we obtained from three different suppliers before making the decision to go with the system Oti Power recommended.

We have since recommended Oti Power to our neighbours and tennis friends interested in getting solar panels installed and passed on Hamish's contact details to them.

Excellent experience - however as only recently installed the proof will be in the pudding if after sales service is required.
However, at this time the system is working very well.
