Charlie Sparks installs solar power systems across the City of Sydney, and Waterloo, from the metro quarter through the Danks Street and Lachlan precincts to the terrace streets toward Redfern, is changing faster than any suburb on our run sheet.
That change is the solar story. The new apartment buildings carry flat, accessible rooftops with modern services that solar and batteries integrate with cleanly, strata territory where arrays offset common-area electricity and we prepare the feasibility studies committees need. The suburb’s industrial past left warehouses and workshops with generous roof decks, some converted, some still working. And the surviving terrace rows bring the compact heritage brief we handle across the whole inner south, shade studies, high-efficiency panels, careful placement.
As a local solar company, we stay involved after commissioning: solar servicing, panel cleaning, monitoring, and battery storage where it pays.

Inner-city electricity tariffs are among the steepest in NSW, so every kilowatt-hour a Waterloo roof produces is bought back at premium rates. Precinct strata arrays, warehouse systems, and terrace installs alike take a genuine slice off the bill.
The federal STC solar rebate is deducted from your quote upfront and scales with system size, meaningful on terraces, substantial on precinct and warehouse arrays. We handle every eligibility check and all paperwork.
Your own solar generation blunts every retail price rise, and with battery storage, outages pass unnoticed, lifts, access systems, and household essentials keep running while the grid sorts itself out.
Waterloo is being rebuilt for the next fifty years inside a council area committed to net zero, and rooftop solar across its new precincts and old streets is that future arriving early.
We’ve kept the process straightforward, with no high-pressure sales calls or surprise charges along the way.
We are around Waterloo, Zetland, and Redfern constantly, so solar faults get attended within days by a crew that knows the suburb street by street, not a subcontractor navigating by app.
Current Clean Energy Council accreditation across every solar installer, the requirement behind your STC rebate, with all work to AS/NZS 5033 and AS/NZS 4777 and full documentation handed over.
New precinct strata processes, warehouse deck arrays, terrace shade studies against a changing skyline, and City of Sydney approvals, Waterloo's actual solar questions are ones we answer week in, week out.

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.

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.

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.
