Charlie Sparks provides solar installation across the City of Sydney, and the Railway Square precinct, where Broadway, George Street, and the Central Station approaches converge, is a corner we know well.
Solar power systems here serve a distinctive building mix: hotels and backpacker accommodation trading around the clock, education and student housing buildings serving the UTS and TAFE precinct, heritage rail-era commercial structures, and mixed-use blocks toward Haymarket and Ultimo. Each brings its own questions, structural capacity on older buildings, rooftop plant coexistence on newer ones, and approval pathways through building management or owners’ corporations, and we work through all of them routinely.
As a local solar company, we also handle the aftercare: solar servicing, monitoring support, and battery storage when the numbers make the case.

Hotels, education buildings, and retail around the precinct run heavy daytime electricity loads, exactly when solar panels produce, so every kilowatt-hour generated on the roof is bought back at peak commercial rates.
Commercial and strata-scale solar systems attract substantial STC incentives under the federal solar rebate, deducted from the project cost upfront. We manage every eligibility check and lodge all paperwork before installation begins.
On-site solar generation hedges building budgets against electricity price rises and network charges, and with battery storage, essential services ride through outages, resilience guests and tenants never have to think about.
The Railway Square precinct moves tens of thousands of people daily through a council area committed to net zero, and rooftop solar on its buildings is clean generation exactly where the demand lives.
We’ve kept the process straightforward, with no high-pressure sales calls or surprise charges along the way.
We are around Central, Haymarket, and Ultimo constantly, so solar faults get attended within days and building operators deal with one consistent local team across the asset's life.
Current Clean Energy Council accreditation across every solar installer, with all work to AS/NZS 5033 and AS/NZS 4777 and the audit-ready documentation trail commercial and strata buildings require.
Heritage rail-era structures, rooftop plant coexistence, city access logistics, and approval pathways through management or committees, Railway Square's real solar questions are ones we answer routinely, with Ausgrid and council processes well travelled.

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.

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

Fully NSW-licensed electricians and CEC accredited solar installers, with public liability and workers compensation cover at the thresholds commercial building contracts specify, in place before work starts.

Tier 1 solar panels and inverters from Fronius, SolarEdge, Sungrow, and GoodWe, selected for performance, monitoring depth, and serviceability, equipment specified for a 25-year building asset.

Structural review, plant coordination, access logistics, and approvals are priced into the solar quote from the start. The number we table is the number we invoice, city projects have enough complexity without variations.

Documented, labelled, photographed installations, monitoring that facilities teams actually use, and rooftops left as specified. Then ongoing solar servicing, because the install is the start of the relationship, not the end.
Explore our recent solar installation projects that highlight our workmanship, attention to detail, and ability to deliver efficient, cost-saving energy solutions for every property.
Railway Square timelines are driven by approvals, access windows, and building operations more than the physical solar installation, once sign-off is in place, most building arrays are mounted and commissioned within days. Your proposal maps the complete program.
Building solar systems size to operational or common-area electricity loads and available structural roof area, arrays from 20kW to well beyond are realistic on precinct rooftops, and high-efficiency solar panels make constrained city decks work hardest. Every design starts from real consumption data.
Yes, every installer holds current Clean Energy Council accreditation, the requirement behind the federal STC solar rebate and Australian standards compliance, and part of the documentation commercial buildings are audited against.
In full, and at commercial scale the STC value is a serious line item. It is applied to the project cost upfront and we manage the entire assignment process, with documentation delivered for the building’s financial records.
Tier 1 solar panels carry 25-year performance and 10 to 15 year product warranties; solar inverters run 5 to 10 years with commercial extensions available. Our workmanship warranty covers the installation itself, documented to contract standard.
