Skip to contentCharlie Sparks installs solar across West Pennant Hills NSW 2125, from the streets around Thompsons Corner and Pennant Hills Road to those bordering Cumberland State Forest and Castle Hill Road. Shared by The Hills Shire and Hornsby Shire, it is a suburb of detached homes on leafy blocks.
Trees are the making of the area and the main challenge for solar. A roof can be in full sun at ten and in dappled shade by two. We measure that properly, then design with panel-level electronics so one shaded panel does not drag down the rest.

Solar Inverter Installation & Replacement
Large homes carry large bills, mostly from cooling, heating and pool equipment. A system designed around your sunniest roof faces covers a real share of that, even where trees limit the hours of full sun.
Eligible systems receive the federal STC rebate. It is taken off your quote so you see the true price, and our team lodges the claim. We check battery incentives at the same time if you want storage.
With panel-level optimisation, each panel works independently. A branch shading two panels in the afternoon affects only those two, so the rest of the array keeps producing at full strength.
Solar lets you cut your household emissions without removing a single tree. Careful placement keeps panels off the most visible roof faces where that is possible, preserving the look of the home.
On a shaded site, the survey decides everything that follows, so that is where we spend the time.
An estimate based on roof area alone will overstate what a shaded system produces. We measure shading on site and give you a realistic output figure, so the savings you expect are the savings you get.
Every installer on our team holds Clean Energy Council accreditation, which the STC rebate requires. We work to the AS/NZS 5033 and 4777 standards and give you the compliance certificate on completion.
Terracotta tiles are brittle and need the right brackets and a careful hand. We also lodge the connection application and advise if The Hills Shire or Hornsby Shire has any rule affecting your property.

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

NSW licensed electricians and CEC accredited installers carry out the work, covered by public liability and workers compensation insurance on each project.

We pair Tier 1 panels with SolarEdge, Fronius, Sungrow or GoodWe inverters and optimisers where needed, all supported by warranties in Australia.

The output and savings in your quote allow for shade, and the price includes tile work, optimisers and any switchboard upgrade. Nothing is added later.

We walk tiled roofs with care, replace any broken tiles, seal every penetration and conceal cabling. Gutters and gardens are left clean when we go.
West Pennant Hills is on the eastern edge of the ground we cover, all of it within The Hills District. Cherrybrook, Castle Hill, Baulkham Hills and North Rocks are our nearest stops from here, and the full set of suburbs follows.
One day for most homes. Large systems, multi-level roofs and installs with optimisers on every panel can take two. We set out the expected time in the quote and book a date that suits you.
Often, yes. We measure how much sun each roof face gets and use only the productive ones. Optimisers let each panel work on its own, which limits the effect of partial shade. If the shading is too heavy for a sensible return, we will tell you.
Yes, with the right method. Terracotta is more fragile than concrete, so we use brackets made for it, lift tiles instead of drilling them and replace any tile that cracks. The roof remains weathertight when we finish.
No. We design around the trees you have. In some cases light pruning of an overhanging branch improves output, and we will point that out, but the decision is yours and any council rules on tree work still apply.
Our installers are Clean Energy Council accredited. The STC rebate comes off your quote and is lodged by us. Panels have a 25-year performance warranty and ten to fifteen years of product cover, inverters and optimisers have their own manufacturer warranties, and our workmanship is guaranteed.
