Highly Recommend Killawatts!

We recently had solar panels, a battery, and an inverter installed by Dave at Killawatts, and we couldn’t be happier with the experience. Our house is older, so the installation came with some challenges, but Dave handled everything with incredible skill and professionalism.

Not only did he navigate the tricky setup seamlessly, but he also worked through some seriously hot and soupy conditions without cutting corners or compromising on quality. His attention to detail, problem-solving ability, and overall work ethic were top-notch.

If you’re looking for a reliable, knowledgeable, and professional solar installer, Dave at Killawatts is the guy to call.
Highly recommend!

Great Experience

The quote was supplied promptly and followed by an onsite visit to answer any questions and to ensure there was nothing concerning about the house that would impact the quote or installation. This was done without pressuring me into making rapid decisions. He took into consideration my future plans such as switching from gas to electric hot water and purchase of an EV.
Solar panels, inverter and battery were installed. The installation went smoothly and, at my request, the meter box was upgraded. He was punctual and the work site was kept tidy.
David was polite and communicated well. He ensured that I understood the system at completion of work and that I knew how to contact him if there were any issues. I highly recommend him and would happily recommend him to family and friends.

Fantastic products, service & knowledge

David from Killawatts has been excellent to deal with. He provided quotes very promptly and was happy to answer questions and work with us to refine the system. He was quick with all communications.
We had panels, inverter and battery supplied and installed.
The system was being added during a renovation & he fitted in with what worked with the builder’s schedule. David came when he said he would & was very reliable.
His work was very neat, and he kept the site tidy. There were a few things that needed sorting out with the existing meter box and he was happy to sort them out.
The hand over of the system was clear and he helped us get set up on the monitoring app etc.
Can’t recommend Killawatts highly enough.

Very happy with the instal

The whole process was easy from the quote to commissioning. David was easy to communicate with and did a thorough job. He took the time to work out the best orientations and placement of panels on the south facing skillion roof. He answered questions and gave advice, but didnt push to upsell like some installers do. I’m very pleased with the result.

Professional service

David was prompt in quoting and patiently answered our questions over the phone, as well as in person and at the home, where he also inspected the tile roof to confirm the details of installation and that there would be no variation to the original quotation. He kept us informed of the steps required in installation, and arrived on each of the four days required for installation at pre-agreed times. He carefully explained any alternatives that we raised for the system quoted, with a focus on achieving value for money for us.

Stress free installation

Dave was a consummate professional who guided us through the installation process with clear direction, he went above and beyond by coming back after the job to install our inverter cover as this came after the installation of the main system. Would not hesitate to recommend him to friends and family.

Good Job at a Good Price

David knows his stuff. He kept it simple and was straightfoward in his approach. Is a local business which was our preference.
Was able to accommodate our request for black panels and his apprentice did a great job in the roof space in challenging conditions, it was very warm.
System delivered promptly and with no bother. Would recommend.

Highly recommended

Killawatts was responsive, and provided a great solar system that was in budget. They helped with the removal of the existing system, the roof was made good prior to installing the new system, and did all leg work to set us up with endeavour energy. We're very happy, and we highly recommend Killawatts.

Great consultation and installation

David from KillaWatts provided extensive consultation, sound advice on the most appropriate system and seemless installation of our new system. He was patient with our questions, very pragmatic and honest in his advice and very reliable in the delivery and installation.
Definitely would recommend David, especially to those who need advice and are not that familiar with solar options.

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.) Original ratings

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.

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.

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.

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.

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.

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.
