Skip to contentCharlie Sparks installs solar throughout Castle Hill NSW 2154, from houses and townhouses around Castle Towers and Old Northern Road to the commercial and light industrial precinct off Victoria Avenue. The suburb spans both The Hills Shire and Hornsby Shire, and we cover all of it.
That variety means no single system suits everyone. A detached house, a strata townhouse and an industrial unit each have different roofs, rules and usage patterns, so we treat every property as its own design job.

Using solar as it is generated is the quickest way to cut an electricity bill. Homes save on daytime cooling and appliances, while businesses offset lighting, air conditioning and equipment during their opening hours.
Federal STC incentives reduce the cost of eligible solar systems for homes and businesses alike. We include the discount in your quote, look after the paperwork, and check your eligibility for any battery incentive.
A quality solar system can add to the appeal of a property, because it lowers the cost of living or operating there. For owners, it is an improvement that keeps paying its way for as long as the asset is held.
Every solar system installed in Castle Hill replaces grid power with clean generation on site. Households lower their carbon footprint, and businesses can report a real reduction in the emissions from their operations.
Whether we are working on a house or a commercial unit, the steps are the same and so is the standard.
When the company that sold your system also installed it, there is no confusion about who fixes a problem. Charlie Sparks uses its own installers, so one phone call reaches the people responsible for your system.
All Charlie Sparks solar installers carry current Clean Energy Council accreditation, which the STC rebate depends on. Our work complies with AS/NZS 5033 and AS/NZS 4777, and we document it for you at handover.
Townhouses and commercial units often need owners corporation consent, and Castle Hill is split between The Hills Shire and Hornsby Shire. We help you gather what is required and lodge the network application.

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.

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

NSW licensed electricians and CEC accredited installers carry out all of our solar work. Public liability and workers compensation insurance is maintained for every project we do.

We specify Tier 1 panels together with Fronius, Sungrow, SolarEdge and GoodWe inverters. Each has dependable performance and proper warranty backing here in Australia for the long term.

Access, switchboard and metering requirements are assessed before pricing, and each cost is itemised. That means the quote you sign reflects the finished job, with no surprises later.

Tidy conduit runs, square panel rows, sealed penetrations and clear labelling are standard on our jobs. We clean up thoroughly and walk the site with you before we sign off.
Castle Hill is central to the area we service across The Hills District. Our installers also work in nearby Baulkham Hills, Cherrybrook, West Pennant Hills, Glenhaven and Kellyville, along with every suburb listed below.
Most houses and townhouses are completed within a day. Larger homes, battery installs and commercial systems can take longer, and we stage commercial work to suit your business. Your proposal sets out the expected timeframe before anything is booked.
Usually, yes, although the roof is often common property, so the owners corporation must approve the installation. We provide the system details, plans and insurance information your strata committee will ask for, and install once consent is in place.
We do. We install commercial solar for warehouses, showrooms, offices and strata industrial units around Victoria Avenue and Showground Road. The system is designed from your interval data, and we manage approvals with the building owner and the network.
Savings depend on how much power you use during the day and the size of the system. After reviewing your bills, we give you an estimate of annual generation, self-consumption and savings in writing. A battery increases the share of solar you use yourself.
We apply the STC rebate to your quote and lodge the claim. Panels come with a 25-year performance warranty and 10 to 15 years of product cover, inverters with 5 to 10 years, and our CEC accredited installers back their work with a workmanship warranty.
