Professional provider
The quoting process was excellent. David was patient and thorough in his responses to detailed questions. He is highly professional, articulate and thoughtful in his approach and straightforward to deal with. Installation went smoothly. (However, we are still resolving an issue with provision of information on consumption etc. from Goodwe's HomeKit which David is in the process of addressing.)26 January 2021
Great installer
Really happy with KillaWatts, the only installers who actually looked on our roof before quoting and making us feel confident that they were quoting us on a system that was suited to our roof. They were professional and a pleasure to work with and they quoted and installed a system that suited us rather than trying to sell us on a specific brand or size they wanted as seemed to be the case with some other providers.04 December 2020

he gave a detailed quote with optionshe actually got up on the roof
the installation went well tidy and was all set it up

Top quality for reasonable price
David at Killawatts was very professional and accomodating. He discussed options during the quote and was accomodating to our requests. Dave obviously take great pride in his work, taking time to do a thorough job. I've inspected a lot of the work in the roof space and it is clean and professionally done. We've had the system running for 8 months now with no problems and great results. The price wasn't the cheapest (or the most expensive) but solar is a long term investment and Killawatts provided a good value service that I have confidence in for future returns.Panel rating: 5/5

Great communication and customer service
Dave from Killawatts was a pleasure to have around our house doing the installation, he has great communication prior and post installation. He went out of his way to answer any and all questions. Would highly recommend.12 March 2020
Brilliant installation from start to finish
Friendly and informative electrician, provided a tailored quote for our installation request. Was very happy to answer any questions during the quoting phase and throughout installation. Competitive pricing and using quality materials and parts. Honest and up front about different options for installation, and you could tell he really knew what he was talking about. Not pushy or salesperson attitude, genuinely interested in getting the right products and installation for us at a good price.Installation was a simple and painless process over a couple of days. Time-frames provided were accurate and turned up when he said he would. Very neat and tidy installation on both the roof panels and inverter. Assisted with forms and information to arrange smart meter installation. Provided all information via text and email in a timely and professional manner.
Highly recommended for solar installation.

Thanks Dave, appreciate the review!15 January 2020
Amazing work from a diligent and respectful tradesman
David did an amazing job in our solar installation. He was diligent, reliable and respectful of our property. He communicated well and was very honest and clear in explaining how the system would work both before and after the job was completed.He showed up when he said he would, was careful and polite and finished the job in the time frame promised. It was quite hot weather during our service and yet he still did a complicated job on a hot and difficult day. He explained clearly how to organise the grid connection and helped me see how the inverter would work. I would highly recommend him to anyone considering a solar installation, I am so glad I didn’t use anyone else.

Excellent installation
Was very happy with my interactions with David prior to and during the installation of our 9kw system. During the sales/quoting process he was knowlegable without the sales patter of some of the other companies. He communicated well and was on time when visiting site to confirm quote. The quote was competitive. David started the installation when he said he would, and finished it in a timely manner, with comprehensive handover information/documentation provided. David worked tidily and safely. System was installed approx 1 month after first request put through solarquotes, which I thought was a good result as well.Would have no hesitation in recommending David.

Friendly personal service and a good price
Well worth calling Dave if you are looking at getting solar. Will give straight advice about what is best for you, and takes the time to explain things well. We had him install a 9.9kW system, and couldnt be happier. Really professional approach and friendly as well.Panel rating: 5/5

We're very happy with our solar power system
David communicated clearly during the quoting process and the price was competitive with the 2 other quotes we got. The installation took place at the agreed time. We did have a problem with incompatibility between our modem and the inverter which meant that we couldn't monitor our system right away but David liaised with the manufacturer of the inverter until this problem was remedied.We're very happy with how much solar power we generate, how low our electricity bills are and that we can monitor the power we generate on our computers and phones.

David from Sparky Solar & Electrical (now known as Killawatts) was great, his quote was competitive and professional unlike some of the other suppliers. His workmanship was second to none (I’m a retired engineer).
We live in a retirement village which means that our power meters are housed in a separate meter room. The problem we had was that Origin (and probably other suppliers) would not change our meter because it required the power to be disconnected to other homes in the village. This meant that we had to find a Level 2 Electrician to change the meter connections before Origin would change the meter. This delayed our solar installation by at least 3 months and it cost us an extra $1,200.
David from Sparky Solar & Electrical alerted us to these problems before we placed an order for the solar system. I hate to think what would have happened if we had gone with one of the other companies who were pushing us to sign up without a full site inspection.

We were very impressed with David from Sparky Solar and Electrical. He came to the house before quoting, and explained the various options clearly. The quote was reasonable and about what we were expecting to pay. The work was completed within a couple of weeks, and his standard of workmanship was excellent. I would recommend this service.8 months later we asked Ngaire: "Are you happy with the performance of your system so far?"
The system is working well, we have a pool with infloor cleaning system and solar pump for heating, so running pumps to utilise our solar production in the middle of the day is having a big impact on our electricity bill.27 October 2018
While I have just had the system installed I am unable to determine the full effect of the system on my power bill as I am waiting for the smart meter to be supplied by my electricity supplier. However I have run some tests on the system and the results show that I should get a significent reduction in my power bill.
David from Sparky Solar and Electrical was very professional from the the first conversations I had with him right through to the hand over of the finished installation. I would have no hesitation recommending Sparky Solar and Electrical as a supplier.

We were extremely impressed with Dave, he was very knowledgeable about the system he was selling. Dave explained everything about the system we had installed, an installation was done in the time frame he told us. We would recommend Dave without any hesitation to other buyers.

David is a local guy which really sold it for me due to the fact that if something goes wrong he will be the coming to fix it not some sub contractor. Also David was the only solar quote that actually got on the roof and did all the measurements and quoted what I could actually fit on my roof. Very easy to deal with with communication outstanding. The work was started on the day he said and completed within 3 days. He explained everything I needed to know and made me very comfortable with the decisions I made. Would recommend to anyone.

David Russin has to be the most informative, patient and helpful person I have ever met. He had the time to explain to me every detail of what he was doing. Nothing was a problem for him. He was on time every time and if he couldn't make it he would ring me. I would recommend David to anyone as he was the best out of all the quoters :-)

We are still awaiting our new meter from Origon but David Russin guided through the quote and install experience with a great deal of care and follow up info. We have been very happy with the whole process to date. A lot of others immediately google your roof etc but David was quite quick to turn up and inspect and talk in person

David from Sparky Solar & Electrical was the only one of 6 installers I contacted who actually turned up and physically inspected and measured my site for a quote rather than google map overly optimistic estimates from others. This allowed for real time discussion on available options and I am very happy with my installed system. David was realistic with time frames and installation ran smoothly and very neatly. No hassles at all.

Sparky were so professional in their advice and customer service, they have done other electrical works for me and I would be happy to refer them to friends and family alike. Information provided was prior installation and fully followed up with information and training on the online system for checking usage data.

David was knowledgable, punctual, thorough, neat, and very pleasant (and great with our dogs). He kept us informed of what he was doing via email or SMS. David also identified a problem with my old solar array switch and replaced it.
In fact I have recommended the company to my daughter who will also be getting a system from them.

I contacted Dave from Sparky Solar & Electrical and told him I was initially after some advice regarding our old, 2kW, system. Dave was happy to assist and prompt in getting to my home. After initial discussions Dave inspected our old system and told us it was best to replace the entire system with a new 5kW rather than adding 3kW. We then went up on the roof and Dave showed me the many problems with our old system. After some more discussion Dave offered a 2 step price: 1 for the new solar and the 2nd for other work we required. We agreed on the spot and Dave was back within a couple of weeks to carry out the work.
All work was completed on time and within the original quote.
We would have no hesitation in recommending Sparky Solar & Electrical as a very professional enterprise. In fact, I believe it was on our recommendation that our neighbours selected Dave to install their new 6kW system
