Charlie Sparks works across Alexandria regularly, from Botany Road and the warehouse precinct through to the terrace streets nearby.
The commercial stock is the opportunity here. Before any design work we check two things: what the roof structure will actually carry, since older industrial framing was not built with an array in mind, and who controls the roof, because many businesses here lease rather than own. A short lease with no landlord agreement is a poor foundation for a twenty-five year asset.
And because we are local, we are still here when you need a service call or a warranty claim.

Electricity is a major operating cost for any business running lighting, cooling, ventilation or equipment through the day. Solar covers that load at the point of use, which is where the savings are largest and most predictable.
Smaller systems attract the federal STC incentive, deducted straight from your quote. Larger commercial systems generally fall under a different certificate scheme, and we will tell you which applies to your project and handle the paperwork either way.
Generating on site insulates you from retailer increases and network charges you have no control over, and makes a significant operating cost predictable when you are budgeting a year or more ahead.
One large Alexandria roof can displace more grid power than a whole street of terraces. Every unit generated on site is one less drawn from fossil fuel generation, and for a business it is a measurable reduction rather than an offset bought elsewhere.
We have kept the process straightforward, with no high-pressure sales calls and no surprise charges along the way.
Our crews are through Alexandria and the surrounding suburbs constantly, so a fault is attended in days, not weeks. On a commercial site that response time is the difference between a minor fault and months of lost generation.
Every installer on our team holds current Clean Energy Council accreditation, and every system is installed to AS/NZS 5033 and AS/NZS 4777 with proper isolation, labelling and handover documentation. On commercial sites we work to your induction and safety requirements as standard.
Metal deck, membrane, sawtooth and concrete on the warehouse conversions, slate and terracotta on the terraces, we have worked across all of them. We know when to ballast rather than penetrate a membrane, how to set tilt angle and row spacing so panels do not shade each other, and how to read an older roof structure before loading it.

I highly recommend Charlie.Posted on Google Farzan MaghamiTrustindex verifies that the original source of the review is Google. I recently had Charlie from Charlie Sparks install a Tesla Powerwall 3, a new 17kW solar array, and a backup gateway at my home, replacing my old solar system, and the experience was outstanding. Charlie provided a rough quote over the phone, which was reasonable, so we arranged for him to inspect my property. During the inspection, he was thorough, climbing onto the roof to assess the setup. We discussed optimal placement for the Powerwall 3, and he suggested upgrading to a 17kW solar array if budget allowed, without being pushy. His initial quote was competitive, and after I opted for the new array, he provided a revised quote that was very well-priced compared to multiple other quotes I obtained. Charlie and his team were punctual for both the inspection and installation, which impressively happened less than a week later. They efficiently removed the old system and installed the Powerwall 3, 17kW solar array, and backup gateway with professionalism and clean work. Commissioning was seamless, and the system was fully operational the same day. During the quoting process I realised that using a Tesla-certified installer is critical for the Powerwall warranty - Charlie confirmed his certification, which I verified with Tesla, so everything checked out. (Tip: always ensure your installer is Tesla-certified for a TPW3!) The day after installation, Charlie followed up with suggestions for optimising the Powerwall 3 configuration. Since those tweaks, the system has been running perfectly. I've already referred Charlie to a friend and will continue to do so moving forward. I highly recommend Charlie and his team for their competitive pricing, timeliness, and exceptional, clean work. Fantastic job!Posted on Google James ZhangTrustindex verifies that the original source of the review is Google. Couldn't have asked for better service. For all the half dozen quotes I obtained prior to installing solar, Charlie and his team were the only ones thorough and attentive enough to actually inspect my roof prior to the quoting. They were knowledgeable and friendly, and have kept me informed during every step of the installation process, I've been very happy with the quality of their workmanship - the proof being their installation completed a week before the "bomb cyclone" hit Sydney - had no leaks or issues post storm. Cannot thoroughly recommend them enough.Posted on Google R CTrustindex verifies that the original source of the review is Google. Charlie has great communication and attention to detail Highly recommendPosted on Google Kristian HanlonTrustindex verifies that the original source of the review is Google. Really easy to do business with. Ran through our Solar options in enough detail that I was confident of making the right decision in terms of capacity and design. Really easy installation and set-up. Great job.Posted on Google R BTrustindex verifies that the original source of the review is Google. Charlie installed solar panels for my house in Strathfield and did an absolutely amazing job. From start to finish, he was professional, knowledgeable, and made the whole process smooth and stress-free. The system works perfectly, and he took the time to explain everything clearly. Couldn’t be happier with the result — so good! Highly recommend Charlie if you’re looking for quality solar installation.Posted on Google Mike KlevianskyTrustindex verifies that the original source of the review is Google. We engaged Charlie and his team to install our solar system. The implementation was exactly as designed and all paperwork was handled by the team. Extremely happy with the overall installation and would highly recommend Charlie and his team. They are honest , take a pride in their workmanship, are extremely fair in their delivery, and we are extremely happy with the overall installation. Well done to you all and thank you for delivering a product exactly as it was discussed and designed. MikeKPosted on Google Mihai PetrescuTrustindex verifies that the original source of the review is Google. I used Charlie to install an EV charger, it came out exactly how I imagined, he cleaned up any debris he made and answered all my questions. I believe I found the electrician I will keep on calling because I am happy with his work.Posted on Google Monika (Monika66)Trustindex verifies that the original source of the review is Google. We just had our panels installed in February, best thing I've invested in for our family home. Our last monthly bill was only $20. It's working so well and so efficiently. I highly recommend Charlie and his team, very efficient, tidy, and professional. You also can't find a better price for value.Posted on Google MitchellTrustindex verifies that the original source of the review is Google. Charlie is a legend—really professional, friendly, and efficient. He did a great job on the roof, not just with the solar install but also by putting in extra effort to make sure the roof was in top condition

Every electrician we send out is fully NSW-licensed and our solar installers hold current CEC accreditation. Full public liability and workers compensation cover is in place on every job from the moment we arrive.

We install equipment with a proven Australian track record: Tier 1 panels backed by local support offices, and inverters from Fronius, Sungrow, SolarEdge and GoodWe. On a commercial system expected to run for decades that track record matters far more than the headline price.

Our quotes are scoped properly the first time. Roof structure and membrane condition, switchboard and supply capacity, access, and any landlord or lease considerations are all assessed before we price the job.

We work the way tradespeople used to: straight conduit, torqued and labelled connections, a swept site, and a proper walkthrough before we leave. Call six months later with a question and you will get an answer, not voicemail.
Alexandria sits at the northern edge of our Eastern Suburbs service area. If your suburb is on this list, our team is already working nearby most weeks.
Houses are generally completed in a single day. Commercial and warehouse systems run from two days to several weeks depending on size, with structural assessment and network approval ahead of that. Your quote sets out the full timeline before you commit.
Terraces here are area-limited and typically suit 3 to 6.6kW. Warehouse conversions and commercial premises are a different scale entirely, commonly 30kW upward, and are sized from your interval data, supply capacity and what the roof structure can carry rather than from available area alone.
They are. Every installer on our team holds current Clean Energy Council accreditation, which is what makes your system eligible for the applicable rebate and compliant with Australian standards.
Yes, and you will never see a form. For residential-scale systems the rebate comes off your quoted price before you pay anything. For larger commercial systems we explain the applicable certificate scheme and manage that process for you.
Expect a 25-year performance warranty and a 10 to 15 year product warranty on Tier 1 panels, and 5 to 10 years on inverters depending on the brand, with extensions often available. Our own workmanship warranty covers the installation, including mounting and any roof penetrations.
