COMMERCIAL SOLAR LAKE MACQUARIE

Commercial solar for Lake Macquarie businesses, from Cardiff, Teralba and Boolaroo workshops to Charlestown and Belmont shops, clubs, marinas and caravan parks. Clear, free proposal first.

LOWER ELECTRICITY BILLS

For Lake Macquarie businesses with steady daytime power use, such as workshops, retail, clubs and caravan parks, solar can cut how much you buy from the grid. Savings depend on your system size, usage, electricity rates, roof position and shade.

BETTER LONG-TERM ENERGY PLANNING

Venues and sites with long opening hours feel power price rises the most. Producing part of your electricity onsite helps you plan, and a system can be designed with battery storage, new equipment or EV charging in mind.

SUPPORT FOR BUSINESS SUSTAINABILITY

Customers around the lake care about local businesses doing the right thing. Solar lowers your grid energy use and can support your own sustainability goals.

Reduce Lake Macquarie Business Power Costs with Commercial Solar

Commercial solar is not just panels on a roof. It is a system designed around the way your business uses power.

A shopfront in Belmont or Charlestown may only need a small rooftop system to take the edge off everyday bills. A workshop or warehouse in an industrial area like Cardiff, Teralba or Boolaroo may need a bigger system to support machinery, lighting and air conditioning. Clubs, marinas and caravan parks along the lake often have big roofs and loads that run all day.

We look at your electricity bills, site layout and daily use, then recommend a suitable system. Near the water, we also think about salt and dust on panels, mounting and cabling. We explain what affects the installation cost, including roof condition, system size, inverter selection, safety requirements and any switchboard work. See our switchboard upgrades page if your board needs attention first.

Commercial Solar Around Lake Macquarie and Newcastle

Harris Electrical & Solar installs commercial solar for businesses across Lake Macquarie, from Morisset and Toronto in the south to Belmont, Warners Bay, Charlestown and Cardiff, as well as Newcastle and Maitland.

Every business uses power differently. Some trade standard hours, others open early, close late or run equipment around the clock. When we design a system for a Lake Macquarie business, we look at roof direction, shade, access, electrical demand, switchboard condition, site safety and future needs. We can also talk through battery-ready options, EV charger planning and upgrades to an existing system.

If you are comparing commercial solar installers around the lake, pick a team that understands both solar and electrical work. That is us. We are CEC accredited, our electricians are licensed and we stand behind our work. Want solar at home as well? See our Lake Macquarie solar page.

Replace existing light with ceiling fans . Excellent job , the electricians were very friendly and respectful of my home and very tidy. I was very grateful and impressed that my job was brought forward by 3 days due to another job of theirs completing early. The entire experience from our initial phone enquiry to scheduling and final install was seamless. We will definitely recommend them to anyone needing work done. Thanks Guys

Highly recommend Harris Electrical and Solar! They recently installed a Sigenergy solar system for us, and the entire experience was outstanding. The team was incredibly professional, friendly, and took the time to explain how everything works, including setting up the mySigen monitoring app. The installation itself is neat, tidy, and running perfectly. It is rare to find a team that combines top-tier technical expertise with such great customer service. Thank you for a fantastic job!

Harris Electrical are amazing. Despite not installing our off-grid system. They were able to help us over the phone and then when it wasn't the system issue but something else they came out with a generator (in case) on a Sat evening to help restore power. Then they trained us on the system so we can be more self sufficient and followed through with check-ins over the coming days. I am highly impressed especially after the lack of service given to us by the original installer.

2 years ago we had a 10kw solar system & 8 kw inverter installed at our house by Harris Electrical & Solar.Kyle did a great job of designing the Solar System to suit our house perfectly,and organising everything to get the job done including switchboard modifications and HWS timer.Kyle spent a lot of time explaining how the system works and what we needed for the best system for us.The installation team were very professional and did a great job,very neat.The system works perfectly & were very happy with it,so 2 years later in August 2026 we asked Kyle about adding a battery.He designed a great system that suits our house and existing solar system.Also with a gateway for black out protection. It is all running really well & our electricity bill is tracking very low which is what we wanted.We would like to thank Kyle and the Harris Electrical and Solar team for their great work and we would highly recommend Harris Electrical and Solar.

I've held off writing this review because I know you only get to do ONE Google review per business, and for such a huge investment, I wanted to give everyone (both the business and the review readers) the benefit of a full, complete and time-tested review. Cooper and the team installed our ground-mounted, 21.6kW Solaredge solar system in April 2023. We were huge electricity users at that stage, with underfloor heating (our main heating source for Winter) being a big chunk of our annual 38MW usage. With the prices of electricity starting to increase hand over fist, we had to think of better solutions to our needs. The solar system definitely helped our situation and kept our electricity costs at bay, despite price increase after increase. But I'll admit it was when Cooper and the team installed our 48kW Sigenergy battery in August 2025 that really tipped things in our favour, together with our moving over to Amber Electricity as our electricity provider, and being willing to monitor and utilise the wholesale electricity market. We also added a fireplace in June 2025 to move away from relying on the underfloor heating, as firewood on our property is free. Before any of these changes, our average monthly electricity bills were $476 from April 2019 to April 2023 (no adjustment for increases on earlier bills or for inflation). Since August last year, with the battery installed and being with Amber, our TOTAL cost with Amber for the last year has been a credit of $21.72. No, I'm not kidding. And that's the total cost, including daily supply charges and Amber's subscription fees. So we paid NOTHING for electricity and being connected to the grid, over the last year. In terms of payback periods, our high-end system (including ground-mounted solar, battery, blackout backup, relays to control the underfloor heating, all meterbox work and the fireplace installed) was not cheap, however from where we were previously and at the electricity prices we were paying in August 2025, our payback period on the whole lot is LESS THAN 5 YEARS. And if we separate the fireplace out and reduce our annual usage to take that into account, our solar system + battery still comes in at around 8-9 years payback, which is still pretty good (considering the bells and whistles it has, the quality, and the ground-mounting adding about $25k alone to the total cost). With regards the workmanship and professionalism of Harris Electrical & Solar, and the quality of the products installed, definitely 5 star! Cooper is wonderfully friendly, insanely knowledgeable and happy to explain things to me in the minute detail that my brain needs. The crew are so friendly and skilled and an absolute pleasure to have working here. They do a stellar job and leave the site wonderfully clean. There were, as there often are, some teething issues, but the guys came back whenever required and worked them out to get everything functioning properly. The concrete baseboard under the battery cracked when the battery was first installed, which was cosmetic only, but they focussed on getting the system up and running, and then return at a later date to take it apart, replace the baseboard and have it all working again by that same afternoon. We even had a power blackout the very first night that the battery was installed but were blissfully unaware, as the blackout backup on the battery kicked in without even a flicker - we were only alerted to the blackout when our neighbours saw our lights on and sent us a text! So yes, I VERY highly recommend Cooper and the team at Harris Electrical & Solar. We have been and will continue to be returning customers. And I love that they're local and focused on ongoing relationships with their clients, not just to get your money for an install and then forget you. Bravo, guys .. you've been instrumental in helping us massively reduce our electricity costs, immediately and well into the future.
