Maximising Your Energy Savings with SolaXs

Electricity prices in NSW have climbed steadily, and for most households on the Mid North Coast, solar is now one of the most straightforward ways to cut recurring costs. But the question isn’t just “should I get solar?” – it’s “how do I make sure I actually save as much as possible?”

This guide covers how residential solar installation reduces your bills, which system sizes suit local homes, what batteries add to the equation, and the government rebates available right now. SolaXs has been installing solar across the Mid North Coast for 25+ years, and the numbers below reflect what local homeowners are actually seeing on their bills.

How Solar Panels Cut Your Electricity Bill

• Self-consumption: Every kilowatt-hour your panels generate and your home uses directly is one you don’t buy from the grid. At current NSW rates around 30-35 cents per kWh, that adds up fast.
• Feed-in tariff: Surplus power exported to the grid earns a feed-in credit, typically 5-8 cents per kWh with most NSW retailers. It helps, but self-consumption pays far more.
• Time-of-use optimisation: If you’re on a time-of-use plan, solar offsets peak-rate usage during the day (often 40+ cents/kWh), which significantly increases your savings compared to a flat-rate tariff.

The core principle is simple: use what you generate, and export the rest. The more of your household load you can shift to daylight hours, the better your return.

Mid North Coast Sun Hours and What They Mean for You

Port Macquarie and the surrounding Mid North Coast region averages around 5.2 peak sun hours per day – that’s a strong solar resource compared to southern capitals. More sun hours mean more generation, which means more savings for the same system size.

• A 6.6kW system in Port Macquarie generates approximately 27-30 kWh on a good day, and averages around 24-26 kWh/day across the year.
• A 10kW system averages roughly 37-42 kWh/day annually.
• A 13kW system can average 48-55 kWh/day, suitable for larger homes or homes with electric vehicles.

These are estimates based on local irradiance data and typical panel orientation. Actual output varies with roof pitch, shading, and panel quality – a CEC accredited installer like SolaXs will model your specific roof before recommending a system size.

Choosing the Right System Size for Your Home

System sizing is where a lot of homeowners go wrong. Too small and you leave savings on the table; too large and you’re exporting at low feed-in rates when you could be self-consuming. The right size depends on your current usage, when you’re home, and whether you plan to add a battery or EV charger.

If you’re unsure where to start, the 6.6kW solar system package is the most popular entry point for Mid North Coast homes. It suits the majority of residential households and provides a strong payback period of 4-6 years under current conditions.

Solar Batteries: Do They Improve Your Savings?

A solar battery stores the surplus your panels generate during the day so you can use it at night instead of buying from the grid. Given that feed-in tariffs are low (5-8 cents) and grid power costs 30-35 cents, the financial case for batteries has become much stronger over the last few years.

• Evening self-consumption: Batteries let you run your home on solar-generated power through the evening peak, avoiding the highest-cost grid electricity.
• Blackout backup: Many battery systems provide whole-home or critical-circuit backup during outages – useful for the occasional severe weather events on the Mid North Coast.
• Virtual Power Plants (VPPs): Some battery brands allow you to enrol in a VPP, earning additional credits by allowing the retailer to dispatch small amounts of your stored energy during grid stress events.
• EV charging: A battery combined with an EV charger lets you fill your car on solar power overnight, cutting fuel costs on top of electricity bills.

Batteries don’t suit every situation – if you’re home all day and self-consuming most of your solar already, the payback period extends. SolaXs will model your actual usage profile before recommending whether a battery makes financial sense for your household. Learn more about solar battery storage options.

Government Rebates and Incentives Available Now

Important: The federal STC deeming period drops in January 2027, which will reduce the upfront rebate value. There is also a deeming factor reduction taking effect in May 2026 that will modestly reduce STC values before the larger 2027 step-down. Locking in your system now captures the higher rebate.

The federal government’s Small-scale Technology Certificate (STC) scheme provides an upfront point-of-sale discount on solar systems. The rebate amount is calculated based on your location, system size, and the years remaining in the deeming period – the further out the deeming period, the higher the rebate.

• STCs (solar panels): For a 6.6kW system installed in Port Macquarie in early 2026, the STC rebate is typically $2,800-$3,400 depending on current STC spot price. This is deducted from your system cost by the installer.
• Federal battery incentive: The federal government’s Household Battery Incentive provides a point-of-sale discount on eligible battery systems. Eligible households can save $370 per kWh of usable storage capacity, up to a maximum discount. On a 10kWh battery, that’s a potential saving of $3,700.
• No NSW state rebate currently: NSW does not currently have a state-level solar rebate program running alongside the federal scheme, though various grid support programs exist for specific cohorts.

CEC accreditation is required for your installer to create STCs on your behalf – SolaXs is CEC accredited, so the rebate process is handled as part of your installation.

Monitoring Your System to Protect Your Savings

A solar system that isn’t monitored is a system that could be underperforming without you knowing. Most modern inverters include Wi-Fi monitoring apps that show daily generation, self-consumption, and export in real time. Checking your app once a week takes 30 seconds and catches issues early.

• Compare today’s generation to the expected output for the time of year – a significant drop is worth investigating.
• Check your electricity bill each quarter against your monitoring data. If you’re generating well but your bill isn’t dropping, your self-consumption rate may be lower than expected.
• Most monitoring platforms send alerts if the system stops communicating, which can indicate an inverter fault or connectivity issue.
• Annual visual inspections of panel condition and mounting hardware are recommended, particularly after severe weather.

SolaXs installs systems with monitoring capability as standard. If you’re unsure how to interpret your data or something looks off, call the team directly – 25+ years of local experience means most issues are diagnosed quickly.

Practical Tips to Get More From Your Solar System

Quick tip: Shifting just 2-3 high-draw appliances to daytime hours can increase your self-consumption rate from 40% to 65%+ and meaningfully reduce what you draw from the grid at night.

The physical system is only part of the equation. How you use power during the day matters just as much, especially if you don’t have a battery.

• Run the dishwasher and washing machine during the day: Set these on timers to run between 9am and 3pm when generation is at its peak.
• Hot water systems: If you have an electric hot water system, use a timer or smart controller to heat water during solar hours. This alone can save $300-$500 per year.
• Pool pump scheduling: Run your pool pump from 10am to 2pm rather than overnight. Pool pumps are typically 750W-1.5kW, so this is one of the biggest self-consumption wins available.
• Pre-cool or pre-heat your home: Run air conditioning during solar hours before peak heat or cold arrives in the late afternoon, reducing evening grid draw.
• EV charging: If you drive an EV or plan to, schedule charging during peak solar output hours. Combined with a larger system or battery, this can effectively run your car on sunshine.
• Avoid exporting at low rates: If your retailer’s feed-in tariff is below 6 cents, every unit you self-consume is worth 5-6x more than exporting. Prioritise using power during the day.

These habits don’t require expensive equipment or major lifestyle changes. A basic timer on a hot water system costs under $50 and can pay for itself in a few weeks.

What Can Mid North Coast Homeowners Realistically Expect?

Let’s put real numbers on it. A typical Mid North Coast household using 22 kWh/day with a 6.6kW solar system, 65% self-consumption rate, and a 32 cents/kWh offset rate can expect to save approximately $1,700-$2,000 per year. That translates to a payback period of roughly 4.5-5.5 years on an installed system cost of around $8,000-$10,000 after the STC rebate.

Add a battery and run the same household with 85% self-consumption, and annual savings can push toward $2,400-$2,800. The battery extends the payback period to 7-9 years on its own merits, but many homeowners value the backup power capability independently of the financial return.

Systems installed locally by SolaXs carry a workmanship warranty and full manufacturer warranties on panels and inverters. Over a 25-year panel lifespan, a well-maintained system delivers substantial long-term returns even accounting for modest panel degradation (~0.5% per year).
