Here's everything you need to know about investing in solar panels for your home in the Southern Highlands:

estimated monthly average energy output of a 10kW solar system

How much power do solar panels produce in the Southern Highlands?

Solar energy output in the Southern Highlands varies naturally with the seasons. Thanks to abundant sunshine, solar panels generate the most power during summer. Production does dip in winter, but year-round generation still offers substantial savings.

Ideally, a well-positioned, north-facing 5 kW system with no shading in the Southern Highlands can produce an average of around 14 kWh per day, adding up to roughly 7,480 kWh of clean electricity per year. A 10 kW system could generate about 29 kWh daily, delivering approximately 14,960 kWh annually.

How much do solar panels cost in the Southern Highlands?

The cost of a solar system in the Southern Highlands depends on its size, which we customise to suit your needs. Factors include your current electricity usage (shown on your bill), available roof space, and your budget.

As a guide, a fully installed 5 kW solar system in the Southern Highlands typically costs between $5,000 and $8,000. This investment can save you around $1,800 per year on electricity bills.

For those with more roof space and budget, a 10 kW system generally ranges from $7,000 to $13,000. This larger system can deliver even greater value, with estimated annual savings of up to $3,000.

What direction should my solar panels face in the Southern Highlands?

The direction your solar panels face has a big impact on how much power they produce. In Australia, panels generally generate the most energy when facing north, which is especially helpful during winter when the sun is lower in the sky.

For flat roofs, it's best to install panels at a slight tilt to prevent water pooling. On pitched roofs, panels usually match the roof's angle for optimal performance.

If your roof runs north to south, you can install panels on the east or west sides, depending on when you use the most power. West-facing panels often work best for households with higher afternoon and evening energy use. Aligning your panel placement with your energy usage patterns can increase savings.

You can also install Enphase microinverters to split your array across different roof sections. This approach balances power production throughout the day and avoids large midday peaks. It also better suits time-of-use tariffs to make your system even more efficient and cost-effective.

How many solar panels do I need in the Southern Highlands?

There’s no one-size-fits-all answer when it comes to sizing your solar system. The best setup for your home depends on your energy habits, budget, and what you want to achieve with solar.

Some homeowners aim to cover as much of their electricity bill as possible by installing a larger system. Others prefer a smaller system that pays for itself faster, focusing on offsetting daytime usage when power prices are highest.

Our solar experts will help you work out what’s right for you. We’ll look at your typical energy consumption, your roof space, and your goals, whether that’s reducing bills, increasing energy independence, or boosting your property value.

By customising your system to your needs, we can ensure you get maximum value, reliable performance, and a strong return on investment for years to come.

What solar panel rebates are available in the Southern Highlands?

Going solar in the Southern Highlands doesn’t just help you save on electricity. It also gives access to support from the Australian Government. Through the Small-scale Technology Certificates (STCs) program, eligible homeowners can significantly reduce the cost of their solar installation.

When you install a solar system, the government issues STCs based on how much clean energy your system is expected to produce over its lifetime. These certificates can then be traded in exchange for an upfront discount, taking hundreds, or even thousands, off the price.

Want to know how much you could save? Our team in the Southern Highlands will walk you through your eligibility and apply the available incentives directly to your quote.

How do I find a solar panel installer in the Southern Highlands?

Selecting a solar installer is one of the most important steps in your solar journey. Australia has many solar providers, but not all deliver the same level of quality, experience, or support.

Start by checking if your installer holds the necessary licences and Clean Energy Council (CEC) accreditation. This qualification ensures they meet industry standards and best practices.

It’s also wise to choose a company that specialises in solar technology and offers long-term support, not just quick sales. Look for a team with a solid track record in the Southern Highlands, as experience is key to avoiding common pitfalls like poor system design or subpar installation work.

Finally, take the time to read reviews and testimonials. A strong reputation and positive customer feedback indicate the company stands behind its work and will be there to help if any issues arise in the future.

How long does it take for 1KOMMA5° Sydney to install my solar panels?

When you choose a solar system with battery storage or an EV charger, you can expect an estimated installation timeframe of 2 to 4 weeks from the moment you confirm your order.

After your order is placed, our local installation coordinator in the Southern Highlands will reach out to organise a schedule that suits you best. We’ll handle the details and keep you updated every step of the way, so you can start enjoying clean, reliable energy sooner.

How to choose the right solar panel installer in the Southern Highlands?

The key to choosing the right solar installer is making sure they’re properly licensed and accredited. Beyond that, look for proven experience, a solid reputation, and positive customer reviews to ensure you’re partnering with a team you can trust.

Can I install my solar panels myself in the Southern Highlands?

In Australia, you’re not permitted to install solar panels yourself. It’s a legal requirement that installation is carried out by a Clean Energy Council–accredited professional. Accredited installers and retailers take care of the entire process for you. They take care of everything, from designing the system and selecting the right products for your needs to managing permits, paperwork, and government rebate applications.
