Grand Solar

I bought Grand solar battery and paid 200 dollars deposit and then full amount prior to installation. when the installation day arrived, they advised me that my location was not suitable and paid back what i paid, however they deducted the 550.00 dollars, this was the 200 deposit as well the 350 for showing up. I am not happy that i should be… Read more

responsible for the 200 deposits in good will and 350 for no services provided. customer should not pay when no service is provided

They signed me up for 42kw solar battery for my QLD property in December last year. They promised they would complete installation by mid of January. But every time I called them, they kept delaying saying previous employee had left and they were not aware and they prioritise it asap. This kept on going for 3-4 months. Then when the government… Read more

rebate was about to change, they said as I need it sooner , they will refund my deposit. That was second week of April. Nowhere in qld would now be available to book before may at that time, so I lost my higher rebate due to them. And then I am chasing for deposit refund for 3 weeks. Calling them, e-mailing them but to no avail. They talk very nicely on phone but delivery is BIG Zero. Still chasing for my deposit

Trash company. Really unreadable: they said they will install my solar and after waiting for about 2 months that lost contact and did not even say anything. When I tried to call them they didn’t answer and hung up. Because of this shot company I lost the battery rebate that I would have got. Pls do not go with this trash company.

⭐☆☆☆☆ (1 star) We entered into a fixed price contract with Grand Solar in December 2025 for the installation of a home battery system and paid a $500 deposit. All required documentation was completed and returned promptly. After signing and… Read more

returning the quote, Grand Solar then requested an additional payment of $1,000, which was not clearly explained or justified at the time.

More than four months later, the system has still not been installed.

We have been advised that the company has been unable to secure an installer. This is extremely concerning given that the contract was accepted and a deposit taken months ago.

The ongoing delay is now placing us at risk of losing access to government rebates worth thousands of dollars — a key factor in proceeding with the purchase in the first place.

We have been unable to obtain meaningful communication from the company. Multiple calls and messages have gone unanswered, and we have not received return phone calls.

Despite repeated follow-ups and formal requests for a clear installation date, there has been no substantive response.

At no point prior to signing were we made aware that installer availability could be an issue. From a customer perspective, this raises serious concerns about the company’s ability to deliver on the contracts it enters into.

We are not seeking a refund — we simply want the system installed as agreed.

Based on our experience to date, I would strongly recommend that anyone considering using Grand Solar seek clear, written confirmation of installation timelines before committing.

Cancelled the installation 1 week out, after grid approval, unless I paid thousands of extra dollars. It is a sales front.

RUN AWAY - ALL THE POSITIVE REVIEWS ARE FAKE I signed a contract with Grand Solar in November 2025 for a solar and battery installation and paid a $2,000 deposit. I was advised installation would occur within 2–4 weeks. We are now nearly five… Read more

months later and I still have not received a confirmed installation date. I have sent numerous emails and made multiple calls to their hotline requesting updates. Communication has been extremely poor and I have not received clear information about when the installation will actually happen. I would still prefer to proceed with the installation under the originally agreed terms, but at this stage the delays and lack of communication have been very frustrating.

WHY IS GRAND SOLAR RENEGING ON ITS CONTRACT IS GS 7560 & 7841? IT PERPLEXES ME. https://wwwnicholasnchin.blogspot.com/2026/02/warning-grand-solar-gs7560-gs7841.html This public record documents Grand Solar’s ongoing failure to supply or install the contracted systems for GS7560 and GS7841. As stated in my formal submission: “The contracted solar… Read more

system has not been supplied or delivered.” Despite written assurances, promised installation dates, and full payment of deposits, no installation ever occurred. Grand Solar attempted to impose an unlawful price increase on 19 January 2026, caused entirely by their own delay. Refunds were later issued without explanation, and were accepted strictly under protest. This does not represent any agreement with their attempted termination. The matter is now under active conciliation with Consumer Protection WA. This archive will continue to be updated for public transparency.

I’m extremely disappointed with my experience using this solar company. What was supposed to be a straightforward installation turned into months of frustration. Communication was inconsistent, and I often went weeks without updates unless I chased them myself. This install was for batteries only and was meant to installed by the end of November… Read more

2025 and to date, I am no closer to getting my batteries installed. Getting anyone to take responsibility felt impossible.

The customer service team seemed overwhelmed and uninterested in resolving issues. Every time I called, I was passed between departments, and no one seemed to have accurate information about my project.

I chose this company because they advertised reliability and expertise, but my experience has been the opposite. I regret signing with them and would encourage others to do thorough research before committing.

I have paid $200 deposit and signed 2 orders for Solar batteries in September 2025 to be installed in December 2025. I made several attempts to contact their representatives by email and phone calls but was unable to reach them. I am assuming they have decided not to act on my Orders but have not acted ethically to inform me. They totally ignored… Read more

my communications. This company, in my view, cannot be trusted and should not be in business. This review is written to warn all customers of Grand Solar. Michael

The Grandsolar team was excellent in terms of fast and high-quality installation, straightforward paperwork, and friendly staff who were always helpful and responsive. The pricing was also very competitive. The only issue I experienced was during installation, when an additional $1,100 was quoted for wiring, despite the wiring cost being fixed in… Read more

the original contract by their representative. After discussion, they reduced this amount and added an extra $700 to the final invoice. However, I have escalated this issue to their leadership team, and my request is currently under review. Apart from this, everything else with the company was very satisfactory.

They installed the battery almost one month earlier than the promised date, which I really appreciated and this helped offset the inconvenience of the extra wiring cost.

Overall, I strongly recommend this company for their speed, quality of work, and reasonable pricing compared to others. However, I suggest having someone visit your property to provide an exact quote before signing the contract to avoid unexpected wiring costs during installation.

dealing with scammers take your deposit, the only way you get it back is by contacting Fair Trade. they give you a quote for full system, when really you're getting a partial system with a blackout for only a couple of outlets, like lights – a big disappointment. I hate to think what happens when things go wrong. What warranty are you really getting.good luck

⭐ Product Review: Grand Solar – EPS Misrepresentation & Pricing Trap Rating: ★☆☆☆☆ Location: Sydney, NSW System Quoted: Fox ESS Hybrid Inverter + 41.94 kWh Battery Bank Quote Reference: GS6271 | Date: 02-Oct-2025 ❌ What Was Promised Grand Solar pitched a “whole-home backup” system with blackout protection. The quote included a 10 kW hybrid… Read more

inverter and a 41.94 kWh battery bank—suggesting robust EPS capability. I was led to believe this setup would power my home during outages. ⚠️ What Was Delivered • EPS output limitations buried in fine print—only “Partial Blackout Protection for Essential Services” • No load analysis or appliance compatibility review • No clarity on switching delays, PV blackout behavior, or EPS circuit mapping • EPS likely capped at 3–5 kW despite the 10 kW inverter, due to single-phase constraints and Fox ESS specs • PV shuts down during blackout unless EPS is active and properly configured—never explained The Pricing Trap • Base system cost: $20,630 • Quoted final price: $6,200 (after CHBP discount of $14,430) • CHBP discount is speculative and not guaranteed—terms admit price may jump if the program is delayed or revoked • No itemized breakdown of installation, wiring, or EPS configuration • No explanation of what “backup protection” actually covers—just “light and power only” What I Needed • Transparent EPS output specs (continuous and peak) • Clear list of circuits covered during blackout • Honest load analysis based on my actual appliances • PV contribution during blackout explained (AC vs DC coupling) • Itemized quotes with technical justification—not vague bundles or speculative discounts ️ Final Thoughts This quote felt misleading. Grand Solar presented a high-capacity system but failed to explain EPS limits, backup scope, or real-world performance. The CHBP discount is speculative, and the system’s blackout protection is partial at best. I expected clarity, dignity, and technical honesty. What I got was confusion, upselling, and a quote that could balloon without warning.

⭐ Review of Grand Solar – Deposit Not Refunded, No Accountability Rating: ★☆☆☆☆ Location: Sydney, NSW Customer Name: Fernando Cunha Quote Reference: GS6271 Date of Issue: 02-Oct-2025 ❌ What Happened I cancelled the agreement and was offered a refund of my $100 deposit. It’s now been over two weeks—still no refund. I’ve tried to contact Grand Solar, but their system blocks incoming calls. They operate on a “we call you” model, which means you’re left waiting indefinitely. ⚠️ Why This Matters • No refund despite written offer • No way to follow up—calls are ignored or blocked • No accountability or customer support • If this is how they treat deposits, imagine trying to claim a warranty ️ Final Warning Grand Solar’s communication system is designed to avoid responsibility. If you value your time, money, and peace of mind—avoid them. You may never see your deposit again, and good luck chasing a warranty when things go wrong.

Happy with service, profesional in all interactions and very easy to deal with – Kenan was very professional at all times. Some minor pain damage occurred at the time of his work which I didn't think much of but he rectified which I was very impressed with.

took place on 27/12/2017. The team, led by Kenan, installed a 10.075 kW system, consisting of 31 x 325W GCL solar panels and an 8.2 kW Fronius Inverter (three-phase). They were punctual, polite, and very tidy. Everything was done by the book, and the quality of their work was evident. I was impressed with how smoothly the installation went, and they left the site clean and orderly.

Customer Service: The customer service was exceptional. Grand Solar, under Kenan’s leadership, handled all the paperwork, including organizing the grid connection after the install. This made the whole process stress-free for me.

Performance: Initially, I had some doubts about the GCL panels, but after 7 years of operation, I’m extremely impressed with the returns they’ve provided. The system has performed beyond my expectations, delivering consistent and reliable energy savings.

Overall, I highly recommend Grand Solar for anyone considering solar installation. Their professionalism and attention to detail, guided by Kenan, made the experience a breeze from start to finish.

day promised and removed the old system so i could get the roof refurbished, they then returned 1 week later as promised and installed the new system. All work was done as per the regulations required all cables in conduit and all signage where required. When the installation was complete they removed all rubbish and ran me through how the system worked and all warranty paperwork was handed to myself. Grand Solar helped organise the required electrician for the meter connection. Any time i have needed any help Kenan has always taken my calls and sorted things out so a great customer service.

Grand Solar were able to provide all of this.

On installation day, it turns out that a lot of additional rewiring work had to be done in my meter box, but that wasn't a problem. The installers were very professional, and even though it took them longer than they had anticipated, they went ahead and did the job to the highest standard.

I'll soon be looking to add a battery to my system, and I'll definitely be picking up the phone to Grand Solar again. Thank you for doing such a great job at such a good price.

us to the grid allowing our system to recoup a return from our energy supplier due to our feed-in. And his after sales care and service was one of which we have never really experienced before. His remote monitoring of our systems performance after the installation and follow up phone calls making sure we understood the use of the app he supplied, has also ensured us on how to easily access and monitor to see our usage and grid feed-in. It was very reassuring. He was and still is never too busy to answer our phone calls with any questions we might have even to the point of assisting us with overcoming an issue that had nothing to do with his installation but was due to our geographical position and our Wi Fi which has been rectified, also with his help. My wife and I would not hesitate in very highly recommending Grand Solar to anyone wanting a seriously great system Charles & Patricia Camilleri WYEE NSW
