Very tidy and visually appealing installation. Great company to deal with.

Salesman Matt was on site within 48 hours and his quote arrived a week later (delayed a few days by a computer glitch). The quote was not the cheapest, but it met our requirements for optimised use of roof space and aesthetics. The ultimate setup using all-black panels on black rails with matching hardware right down to a black isolator box matches beautifully with the rest of the house exterior colour scheme, which is black on red, and looks quite attractive.

Installation was arranged 4 weeks to the day from payment of the deposit, and the instal was performed without a hitch. The guys were punctual and chirpy on a cold morning, and left no trace of them being there except for the system itself.

The office followed up quickly with all the necessary paperwork and has answered a few of my dumb questions without any hesitation. They organised the grid connection paperwork and we were re-metered and fully operational within 8 working days.

System quality is rated 4/5 only because we subsequently discovered that module-level monitoring through the inverter supplier's app is only available as an add-on enhancement at additional cost, which wasn't our original understanding.

Otherwise we are overall very happy with the outcome at this early stage.

An all round great service

I found MJJ’s through Solar quotes. From my first contact with Brett their salesman through to the after install service from Jo I have had nothing but a great experience, they came out to my house provided multi options for systems and set ups, explained the pros and cons of each and a cost comparison.

The guys that did the install were great even with the weather being difficult, their workmanship is second to none and they provided a detailed run through of everything after they were finished.

The office team were great, answer all the questions I had along the way and helping with the after install admin with our energy provider

Great Installer, Highly recommend

Great Service all around. The sales person was very knowledgable and professional, i had 3 seperate companies come onsite and quote and the other 2 installers spent 15 mins max onsite. MJJ's sales person spent over an hr onsite with me asking me all the questions he needed and explained to us every component and recommendations for panels invertors etc and the reaaons behind his recommendations. He even went into depth about how the installers will install the system on the roof etc and the connectors and fire saftey precautions they put in place.

Continuing on from their the installers where all professional all in uniform, took their shoes off while coming inside without me even asking them to. They even took all the rubish away with them !!.

The after sales service was great with them following up with me and helping us proccess the paper work with our energy retailer for the smart meter change over.

The system is performing great and would highly recommend them to anyone. Keep up the great work MJJ Solar.

Great looking install and tailored to my needs

Steve from MJJs was great, he ran me through the options based on my needs, listened to my concerns and considered them in the design and quote of the system. The install happened while I was away and they did not disappoint. They were sure to take care of my property and install the system with my requirement to have a beautiful system installed (I.e. not an eye sore from the street). They hit the mark. The admin team from MJJs is also great, very kind and helpful. I highly recommend them over the other installers I was quoted.

Clean and efficient.

The crew came in early, and were very professional. They Got-er-done fast.
They cleaned up after they left and apart from the new panels on the roof there was no trace of them.

I would recommend them to any family member.

Excellent customer experience.

Steve from Sales provided a detailed outline of the system and costing. Jo in Customer Service followed up on all enquires promptly and efficiently. To date a good customer experience. System operational this week and looking forward to power cost savings.

Great company. Great installation

We ended up with a lot of quotes from a lot of suppliers, for different types of systems. We ended up with a micro inverter system with Jinko Tiger 390w panels (25 year product warranty) from MJ Solar. Their price was comparable to other providers and considerably cheaper than our second choice here in the Hunter Valley. Their salesman was professional, friendly and knowledgeable. The installation team were the same and very efficient. The office staff worked with us every step of the way and helped enormously. Overall it was a great experience.

Great local installer, really neat workmen ship really happy with the installation

Sales process was extremely easy. Installation was completed in two days and was a very tidy job with no corners cut. The installation was done to a very high standard. I was there both days and as a tradesman myself I was very happy with the boys and their standard of work. The office staff were all very helpful and organised, nothing was an issue and they were very prompt when replying to emails. This was a stress free process, everything was handled with professionalism and ease.

Low stress solar installation

Steve from MJJ Solar was the only salesman to offer to come to our house in person to assess the solar installation. He took the time to explain the various options available and answer any questions that we had. The quote was very similar in cost to the two others we received, but had more detail and we were more confident that it was right for us.

The installation date was a week before Christmas and everything went very smoothly. The installation team turned up on time, got the job done on a warm, humid day and left everything tidy. More importantly, everything worked just the way it was supposed to.

So far, after nearly 2 months, everything is working well. Our first electricity bill (only 25 days with the solar installed) is about 30% less than the same time last year. Hooray!

Couldn't be happier...!

MJJs Solar were the only company to have someone come and visit our home and provide us with a proposal fully tailored to our property.

Steve, who we dealt with initially, was informative, personable and patient while we worked through the huge volume of information we had received before finalising our decision. Installation was quick and the system is performing so well already, we wish we had done this sooner! The admin team who took over for all the final arrangements were also wonderful and have taken care of everything for us.

Very happy to be supporting a local business and very satisfied with our solar system.

Good installation. Dreadful Customer Service

We selected this supplier after obtaining suppliers from Solar Quotes. We did a lot of independent research and this company seemed to have the answers. Once we paid the deposit all questions we made were ignored totally. It was incredibly frustrating. When came time to install we got a series of questions that we simply could not answer and nor could we get responses to discuss. Eventually I managed to get in contact and demanded that we got our money back as my patience was exhausted.

He got things back on track quickly so we didn't cancel.

When the job was done the placement of the panels were wrong - we wanted some East and West and most North facing. They did them all North and very close to the edge of the roof. Cleaning will be a nightmare as we'll never be able to get to the middle panels.

Emails to discuss were simply ignored. Eventually I managed to contact them and he promised to get back to me and also to supply photos (it's a rental property pending our moving in). I also wanted to know exactly where the inverter had been placed as we expressly asked that it be placed in the garage out of the weather. On the basis of his promise I paid the account in full.

Sadly we've never heard from them again and this weekend discovered that the inverter was placed outside.

I've shown pics on a Solar Facebook page and the general feeling is that it's technically a good installation. We believe that they contracted the installation out and the people that actually did it seemed to care.

But we'd NEVER use them again as there are other installers that also do good work and actually communicate!

excellent sales/disappointing customer service

Salesman came out on site explained everything and the process very professional
Waiting for quote for over 1 week rang to follow it up and appears an issue as it had been sent 3 attempts later we get quote thought maybe a follow up call a few days later for any questions might have highlighted the fact we had no quote
Installation date moved forward very exciting
Day of install we were going away happy for guys to work and left key to lock garage and instructions to leave key inside
Come home no key garage left unlocked 4 days no phone call to advise of issue
Followed up enquiring where key wax they've lost it offered to replace lock or cut new key fine but very annoyed garage not locked and we were not told
Issues setting up wifi get advised will be there next afternoon follow up call wont be till next afternoon all good waiting for 45 minutes contact to see where they are got held up on job advised office were to contact us no contact at all
Providing communication with customer is very important and unfortunately lacking in this area after the sale has been done
Wait now and hopefully the system will deliver results

A great company to deal with

MJJ Solar were the only one's who offered to come and do a site inspection. The others just sent a quote by email. So MJJ was in front from the start. I liked the salesman, he spent 1.5 hrs with me explaining everything and seemed very genuine. I had further questions at a later date and these were answered also.

The installation went well. The team were punctual, very nice and left everything nice and tidy when they were finished.

The customer service has been great and they did submit all of the paperwork for the change to the meter. I have heard from my supplier but have yet to be given a date for this work to be completed.

Overall, a great experience! I was nervous about understanding everything, but found the solarquotes website very useful in helping me understand the process more.

Lowrie Review of MJ Solar

The sales / quoting experience was first rate. They actually came to site, met my wife and I and discussed the proposal before doing the quotation.

Installation was as quoted - in and out on the day they promised. Job site was cleaned up after

Great assistance in securing the gris connection

8 months later we asked Sharon: "Are you happy with the performance of your system so far?"

This has been one of the best decisions we made to put solar on.
Our electricity bill dropped from approx $800.00 to less than $100.00 even though I was using more electricity than previously since I have been home every day for the past year.
Can't thank you and your team enough for all your help and excellent advice..

Prompt, Polite, On Time, On Budget & Tidy.

Great Job done by the crew at MJJ Solar.

From initial inquiry to "up & running" everything happened with no issues. Several options were presented in "The Proposal" (quote) and they were happy to answer any questions and look at other alternatives.

On the day, the boys arrived on time, worked efficiently all day with a friendly nature, made sure every visible item was installed in an aesthetically pleasing manner using a level to regularly check horizontal & vertical.

They completed the installation by getting the system talking to the internet and then tidied everything up before they left.

The MJJ experts clearly knew their stuff. They recommended a SolarEdge package with Optimizers on each panel to improve performance which added a little to the cost but has proved to be well worth the extra.

The package is easily outperforming a friend's simple "string" system just down the road which has an almost identical roof layout.

The monitoring software that came with the SolarEdge Optimizer system, allowed the operation & performance of each individual panel and the overall system to be checked before the boys left the site, and the system was then monitored by the MJJ crew for a couple of days before they declared the installation complete.

A great confidence boost.

This same software allows me to follow the whole system (again down to the individual solar panels) over the internet in real time on my phone or PC from anywhere, providing instantaneous, medium & long term statistics.

I have even been able to download performance data (in 15min increments) to an excel spreadsheet for further analysis.
You couldn't ask for a better solution.

A great job by MJJ Solar .. Highly recommended.

Our installation was delayed due to inclement weather but once they arrived they worked quickly and efficiently. The installation is very neat and unobtrusive including the inverter. The checking and handover at the end of the day was comprehensive and left us feeling we had made a wise choice in selecting this system and this installer.

10.5kW Solaredge MJJ solar install

Overall MJJ were good to deal with, friendly and did a good installation job.

We got a 10.5kW Suntec panel system with a 8kW Solaredge inverter with monitoring. On Sunny days we produce around 40-66kWh of energy and 29-40kWh on heavy rain/cloudy days. All panels are located on the Northern facing roof.

So far for Feb-Mar we can produce enough energy to cover our ducted aircon and still export up to 4kW of solar to the grid.

The monitoring is worth it as you can get a lot of power consumption info to help change habits etc. Thinking after a year we will have enough data to figure out if batteries would work for us but currently they seem too expensive to make sense for us.
