Why Autumn Is a Great Time to Install Solar in Newcastle

When most people think about installing solar, they assume summer is the ideal season. But here’s the truth, autumn is actually one of the best times of year to go solar in Newcastle, Lake Macquarie, the Hunter Valley, Central Coast, and Port Stephens.

With mild weather, solid solar production, and lead times shorter than the summer rush, autumn offers a perfect window to future proof your home before winter energy bills arrive.

If you’re considering switching to solar, here are five powerful reasons why autumn is the smart time to act.

1. Perfect Weather for Solar Efficiency

Newcastle’s autumn climate is ideal for solar panel performance. While summer gets all the sunshine glory, extreme heat can actually reduce panel efficiency. Solar panels work best in cooler temperatures with consistent sun exposure, and that’s exactly what April and May deliver.

• Less heat = better output per kWh installed

• Stable, sunny days in autumn lead to strong solar generation

• You start benefiting immediately with noticeable savings before winter

In fact, solar output in autumn can often rival or exceed summer production on a per day basis, especially if you install a modern, high efficiency system.

2. Beat the Winter Bill Shock

Let’s face it, winter energy bills in Newcastle can hit hard. With shorter days and heavier appliance use (heaters, dryers, hot water systems), many households see a significant spike in electricity costs by June or July.

Installing solar in autumn gives you time to:

• Get your system installed, approved, and running smoothly

• Start saving before your heating and appliance use increases

• Offset your winter bills with feed-in credits earned from autumn generation

By acting now, you’re not just planning ahead, you’re putting yourself in a strong financial position for the cooler months.

3. Shorter Wait Times & Faster Installs

Summer is the peak season for solar in NSW. That means longer waitlists, higher demand, and delays in approval or grid connection.

In autumn, demand is steadier, which means:

• Faster turnaround from quote to install

• Quicker grid approvals and inspection scheduling

• More personalised attention from your installer

At STE Solar, our team can typically complete a system assessment, design, and installation in as little as 7 - 14 days (please enter your correct day estimate) in autumn, well before the next quarterly energy bill arrives.

4. Take Advantage of Current Rebates Before EOFY

The lead-up to the end of financial year (EOFY) in June is the perfect time to maximise solar incentives and make smart upgrades to your home.

Autumn is your chance to:

• Claim current STC rebates while they’re still at higher levels

• Take advantage of the Empowering Homes Program, which offers interest free loans for eligible NSW homeowners

• Prepare for any potential policy changes or reductions that often occur after June 30

Installing solar now means you can include the upgrade in your 2024 - 25 financial planning, or if you're a property investor, potentially claim tax benefits before EOFY.

5. Get Ready for Winter with Battery Storage

If you’re considering solar battery storage, autumn is the ideal time to add it.

Why? Because batteries let you:

• Store autumn’s excess solar production

• Use that energy during long winter nights

• Avoid paying peak winter rates from the grid

Autumn installations ensure your battery is installed and calibrated before winter hits, giving you maximum control over your power use and savings.

Autumn may feel like a time of slowing down, but it’s actually the perfect moment to future-proof your home with solar. You’ll lock in lower bills, reduce winter energy stress, and start enjoying solar savings in weeks, not months.
