KillaWatts Solar Reviews

We follow up with all reviewers after 12 months to see how their system is going since it was installed. These are all the reviewers who have responded to our 1 year follow up:
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.

Waiting for a smart meter installation to get it going Show additional information
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 :-) Show additional information
Dave made the whole installation a no fuss process. Turned up on time, left no mess and carried out the works with little impact on our daily life. Show additional information

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 Show additional information
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.

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. Show additional information

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. Show additional information
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
