Kdec Electrical and Solar Pty Ltd Solar Reviews

We live in Wodonga, in north-eastern Victoria. We purchased a PVA and battery system from a local suppler/installer in 2018. Now some 9 months on, we are happy to share our experience with interested readers on the Solarquotes site.

Our system has 6.2kW PVA of roof-mounted Sunpower cells facing 70% north-west, 30% north-east. These feed an Opal Storage box containing a Sola-X 5.6kW inverter, a battery control system and one LGchem 6.5kWh battery. We also installed a Reposit intelligent controller. The all-up cost was around $15K after the government's energy certificate credits. As a happy surprise, we also qualified for the new (at the time) Victorian Government PVA rebate which paid-back $2,250 from that purchase price. We use Energy Australia as our power supplier.

Our system supplier, KDec, was professional and friendly. The installation was done neatly and took only a couple of days. The certification process and energy supplier arrangements that followed were slower but, overall, the system went live without drama.

Now with several months' experience to comment on, we would have to say we are happy customers. The system works, our power bills are now around $100 per quarter whereas they would be upwards of $800 without the system � and would likely be rising in the coming years given the current energy policy climate. Granted it was a large capital cost to install, we are satisfied we will recoup our net spend in 7-8 years (perhaps less if power prices rise more) which is well within the guarantee period of the components.

The feed-in tariff was 9.9c/kWh when we installed the system. Recently (Mar 2019) Energy Aust has introduced a time-of-day variable feed-in tariff which peaks at 29c/kWh for energy we send to the grid at peak times, plus a shoulder feed-in of 10.9c and off-peak 7.1c. We are yet to receive a quarterly bill based on these new arrangements but obviously the change is beneficial to us and will accelerate the pay-back period.

On reliability, we have had two mysterious system shut-downs for no apparent reason over the months. In these cases the system had to be turned off entirely, then restarted. On one of those occasions it didn't restart properly and I had to poke about inside the Opal box pushing buttons on the battery and inverter (under the telephone instructions of the tech from Sola-X!) to get it going. Statistically that suggests about three such events a year, or roughly 99% reliability. I guess that's not bad for a system this complex, but owners should expect to be a bit hands-on in doing re-starts rather than expect the supplier to always show up to do it.

On the matter of reliability, it's worth adding that the owner has to be vigilant in regularly looking at the software screens that monitor the system's performance to even know when it's off the air, since the house will run anyway, drawing from the grid, if the PVA and/or battery shuts down.

Regarding the usefulness of having a battery, it's probably true that most of the benefit from a solar system comes from the day-time contribution the PVA makes to the house in reducing or eliminating daytime grid consumption, with what's left over feeding back to the grid yielding a monetary benefit. The economics of adding a battery remains contentious. In our case, opting for a battery approximately doubled the dollar spend. To make that choice, a household has to have that money available to spend in that way, and many won't have. We did, and having done our sums we figured that the battery payback, whilst slow, was a better investment than simply leaving that amount in the bank.

The dollar benefit from the battery essentially comes from two sources: direct avoidance of grid costs by charging the battery cost-free from the PVA and using that power later when the sun goes down; and from tariff-shifting where the battery management system charges the battery from the grid at cheaper off-peak times and uses it later in peak-rate periods. On any day these strategies only amount to tens-of-cents or maybe a dollar, so it becomes clear why it takes a long time to see the payback. To us, it is appealing to wake-up to a full battery and use its power during the day to thereby avoid most, sometimes all, of peak-rate grid usage.

How much battery to have is, of course, a good question. Our Opal box can take two batteries but presently we have one. Adding a second would cost around $7,500. It's tempting to think that doing so would allow the house to avoid drawing from the grid at all, but a close look at household usage patterns, and cloudy weather which often causes the PVA to operate nowhere near full output, quickly shows that our house would still be dependent on the grid, at least some of the time, even with two batteries. With unavoidable standing-charges on the energy plan, we doubt the economics of the second battery presently stacks-up.

We were very impressed with Cameron's clear and practical presentation, which was, in fact, more knowledge than sales pitch!
There was nothing wrong with Planet Power Riverina's, KDEC's was just better. (Cola Solar too far away for us)
And then the installation blew us away with pure professionalism......
Extremely happy with both SolarQuotes info and KDEC recommendation!!
Thank you!!

KDEC provided the more comprehensive quote and were the only firm that offered a hybrid inverter (I had asked that the system would accept a battery) included as part of the quote. They also offered varying options including presenting a case for a 6kw system. Pricing was similar however the other firms only offered a standard inverter which meant more cost to connect a battery unlike the hybrid that would accept a battery without needing any other parts, at a cost, to connect a battery.

Another contributing factor was that KDEC use their own employees to install. Interesting I received an unsolicited quote from a business in Sydney, they were offering a special as long as I accepted their quote in the next two hours. They didn't even get past first base.

Thankyou for your effort in providing two business to quote, and it was not as straight forward as I first thought in deciding which quote to accept. Once I had received all quotes it took about a week to finally make my decision. I rang each business to let them know my decision.

Professional installation, sound advice. Too soon to comment on system performance but looks to be performing well. Yet to have the app setup properly on iPhone. Show additional information
Great local company. Service was hard to fault. They turned up on time for any appointments or work. Work was always completed to a high standard and site left clean and tidy. Show additional information
One eventually contacted me and seemed ok. However, I had already signed with another company. Show additional information
KDEC have been very professional throughout the entire process including any followup. Happy to recommend KDEC to anyone. Show additional information
After my initial email contact for a quote I was contacted the following day by the manager of the company and had about 30 minute discussion which resulted in a follow up written quote. I was pleasantly surprised with both the professionalism and reasonable price, so I went ahead. The system was installed shortly after with a high level of quality and care, and the site left neat and clean. Shortly after they returned and did meter change as part of the quote. At all times the personnel from KDEC were professional and informative in their approach, making sure you were comfortable with the process. I never felt out of the loop.
The system has performed flawlessly since being turned on, and has wireless monitoring so we can keep an eye on output with an app on my Samsung tablet, as demonstrated by the KDEC staff.

Planet Power did not follow up with written quote also did return call. One other Gentleman phoned during a conference that he was attending and did not phone back.
I found your site extremely helpful and gave excellent information on Inverters and panels.
I have given your name to others

Kallan from Kdec solar was happy to spend some time explaining the in's and out's of the whole solar experience to me and my eldery mother in an easy to understand manner. No question was silly and he was upfront about the product and the time it would take to install. He also made himself accessible if we had any further questions or concerns.

We were very pleased with Kdec as a service provider, we had a instant quote on the day ,the systems went in as advised the installation was quick, accurate and professional. The systems (we had two solar systems fitted,one at the business and one residential) were up and going within half a day and the power interruption to the business was only minutes. The price was also the cheapest with one other very close and one way over the top. I would recommend Kdec as an installer of a solar system. Show additional information

The sales assistant was extremely helpful and supplied written information along with his advice. I would highly recomend this company to everyone. Very satisified. Show additional information
A lot of the pre-sale information was useful, however when it came down to particulars about energy consumption, bills, separate dedicated circuits etc I found it to be less so. I chased up the installation, I chased up the follow up, as KDEC paperwork was filled out incorrectly delaying other stakeholders in the process (Origin & Ausnet). I would suggest delaying payment until everything"" is fully functional and working in order to hold the installer accountable, because once KDEC had installed panels and they got cash, it was difficult to get anything further from them. Will be interesting to see if pre sale promises around energy savings etc come to fruition. Waiting with interest on the next energy bill. Show additional information
K-Dec where upfront with their information and used Trina Honey Panels and a cheap Chinese inverter Growatt that they have not had any problems only with one unit, it worked but you could not read the screen. Their quote was reasonable and they employ Grade 5 electricians so didn't have to out source an electrician to have my meter installed. They installed everything and had it up and running that afternoon. They were able to connect it as I had an old meter which started to run backwards, which was good. They took images of the Solar panel serial no's and they were Trina Panels. Everything was done professionally. I choose a local company as you can go to their office if you have any problems. Very happy with the outcomes. Show additional information
The solar industry is very confusing and specifications and quality vary considerably depending on who you talk to. Researching panels and inverters could take a lifetime, there are thousands on the market and while there are market leaders, not everybody can afford the best system. My feeling was to get a reputable supplier who has good reviews and customer feedback as well as an affordable system and trust them and their choice of equipment rather than frustrate myself looking through panel specs I don't really understand.
Solar Quotes took most of the work out of choosing the supplier as they have a number of reputable suppliers and installers around the country on their books. I received three quotes and went with the one that offered the best value for money and provided the best service. I chose standard panels but upgraded the choice of inverter to a Delta Solivia as this, to me, is the heart of the system. I resisted the temptation to go for the best performing panels as I didn't feel the extra outlay would be cost justified and also think that there will be new innovations in panels well before the 25 year warranty has expired.
My system is 2 kw which, for a small house with 2 retirees is adequate, output generally tops out at about 1.85kw over the midday peak performance window but I expect this to climb a bit as the fierce 30+ heat of WA subsides in April as these panels perform best at about 25 degrees, above this the output is degraded.
I haven't had the system long enough to see the benefits of the solar system but I did get a an account two weeks after it was installed and there seemed to be some reduction benefits other than the $10 credit for energy fed back into the grid.
Be aware that Synergy in WA will charge you about $35 to process your application and a further $60 to program your meter, this could increase substantially if you don't have a modern meter box.

The initial response from the supplier was very quick; next day from requesting quote. However it took a call and a couple of weeks before a visit. Process and options were explained well. Too many options with panels. Had to change preference when selected panel was not available. Installation was on time as agreed but took 1.5 days over consecutive days. Three weeks since installation and still waiting for inspection to enable installation of solar meter. Process will be at least another two weeks. Have spoken to installer who says he has a lot of installations to process. Have spoken to inspector who says he will complete within 1 week of request from installer. Show additional information
As to the quality of the system the answer lies in the years ahead,
Prompt service.

The company we chose was helpful and pleasant to deal with. However, as with so many businesses that you deal with, the level of attention and follow up seems to fall away somewhat once you have paid your money. Our system whilst installed on the roof is not yet working. The approval and commissioning process is lengthy and somewhat frustrating considering you have already paid out many thousands of dollars. This of course is not the installers fault. Show additional information

Our system took quite a while to get approved by essential energy. It was almost as if they didn't what you to install a solar system!!!

Once we were approved, the system was installed in about 10 days, & the meter changed over 7 days later. The sub contractors who installed the system did a top class job of the installation, was there until 7:00 pm to get the job finished.

The sparky who came to change the meter also did a top class job. All good blokes who knew what they were doing, which reflected in the quality of the finished job.

The information gained from Solar Quotes helped me make an informed decision. Show additional information
All three companies replied very promptly and I cannot fault them.

We are patiently waiting now to have our system installed, so it is difficult to accurately comment on some of these categories.

Thanks very much for your service though, which gave us options and made it easier for us to contact someone in the industry.

Steeline Solar's representative Kallen came to our house and fully explained how best to use our electricity requirements to fully benefit from the solar energy. The installation team were fully experienced and had the system up and running in half a day. Very happy with the outcome. Show additional information
Probably should wait until after the system is installed. Show additional information
