Commercial Solar on the Central Coast

Electricity costs are one of the largest and most unpredictable expenses for Australian businesses. But with a tailored commercial solar system, you can reduce your reliance on the grid and take back control of your bottom line.

At Coastal Solar Solutions, we design and install solar energy systems for a wide range of Central Coast businesses—including offices, warehouses, cafés, schools, aged care facilities, and light industrial sites. No matter your industry, we customise your setup to match your daily usage patterns, building layout, and future plans.

With grid prices on the rise and feed-in tariffs continuing to fall, the real value lies in self-consumption—using more of your own solar power onsite, where it delivers real cost savings. Our commercial solar solutions are built to maximise daytime usage, reduce peak demand costs, and help you make the most of your roof space.

Whether you’re looking to cut overheads, reduce exposure to electricity rate hikes, or show customers your business is forward-thinking, commercial solar is now more accessible and effective than ever.

Choosing the right size commercial solar system is key to getting the best return on your solar spend. At Coastal Solar Solutions, we don’t believe in one-size-fits-all. We tailor every system to your actual site usage, roof space, and business operations.

For small retail shops, cafés, and professional offices, a 10kW to 30kW solar system can significantly cut daytime energy use. These setups are ideal for businesses operating mainly during daylight hours and wanting to offset lighting, computers, refrigeration, and air conditioning.

Medium-sized businesses—like medical practices, hospitality venues, and small manufacturers—often benefit from 30kW to 50kW solar systems, covering more of their base load and creating room for future battery integration or EV charging infrastructure.

Larger businesses, warehouses, and industrial sites can take advantage of 100kW+ commercial solar systems, which offer the highest energy savings and fastest payback when usage is consistent and high.

We use detailed interval data analysis from your electricity bills or meter to assess your load profile and usage peaks. This allows us to recommend a system that doesn’t just generate power—but aligns with your peak demand patterns, tariff structure, and site goals.

And if your operations are expected to expand, we’ll ensure the design includes scalable solar infrastructure—so you can add panels or battery storage down the line without redoing the entire system.

As more staff, customers and fleet vehicles go electric, offering EV charging at your workplace is fast becoming a smart business move — not just a nice-to-have.

But here’s where it gets even smarter: when paired with a commercial solar system, EV charging becomes cheaper to run, easier to manage, and a whole lot more efficient.

By using your own solar power to charge vehicles during the day, you reduce reliance on expensive grid power and increase the return on your solar setup. Whether you’re running a retail space in Erina or a warehouse in Tuggerah, combining EV chargers with commercial solar just makes sense.

• Lower charging costs
• Reduce peak power usage
• Attract eco-conscious customers and staff
• Future-proof your site for fleet electrification
