Maximising Solar Gains with Longer Days: Tips for Daylight Saving Time.
When daylight saving time begins, most of us enjoy the extra evening light and a feeling that summer’s just around the corner. But for households with solar panels, this seasonal shift is more than just a welcome change—it’s a chance to optimise solar performance and reduce reliance on the grid.
With longer, sunnier days, your solar system has more hours to generate power. Here are five practical ways to make the most of that extra sunshine and boost your energy savings.
1. Shift Energy Usage to Daylight Hours
Solar energy is produced during the day—so the more of that power you use while the sun’s shining, the less you’ll need from the grid.
Tips to align usage:
Run washing machines, dishwashers, and dryers between 10 am and 3 pm.
Schedule pool pumps, hot water boosters, or irrigation systems for mid-day operation.
Charge laptops, phones, or power tools during solar production hours.
Use a timer or smart home system to automate appliance use if you’re not home during the day.
The goal is to self-consume as much of your solar as possible, which delivers the highest value.
2. Review Your Energy Plan and Feed-in Tariff
As solar output increases during longer days, it’s worth checking your current electricity plan.
Consider:
Are you getting a competitive feed-in tariff for excess solar?
Are you being charged peak rates in the evening when solar production drops?
Could a time-of-use plan better suit your usage?
A quick review could lead to extra savings, especially if your daytime export is high or your evening rates are eating into your battery’s performance.
3. Optimise Battery Usage
If you have a solar battery, the extra daylight hours mean your system has more time to fully charge before evening. This can increase your energy independence and reduce peak-time grid reliance.
Here’s how to optimise your battery settings:
Prioritise charging from solar, not from the grid.
Discharge during peak usage times (usually 4–9 pm).
Monitor charge levels to ensure you’re not exporting excess energy unnecessarily.
If your battery regularly fills early in the day, it might be time to consider an upgrade—or use that stored energy more strategically.
4. Clean and Maintain Your Panels
Cleaner panels = better performance. Spring and early summer are ideal for maintenance before the highest production months hit.
What to check:
Dust, bird droppings, or pollen build-up on panels
Shading from trees that may have grown since installation
Inverter functionality and solar monitoring data
Spark Energy can conduct a quick professional clean or inspection and make sure you’re not missing out on valuable energy just because of dirty panels or small issues.
5. Track and Adjust Your Energy Habits
Take advantage of your solar monitoring app or inverter dashboard to see:
When your system produces the most power
What times you’re using the most electricity
How much energy you’re exporting vs self-consuming
Armed with this data, you can tweak your habits—for example, pre-cooling your home with solar power before the evening or shifting dinner prep earlier to use solar energy instead of drawing from the grid.
More Sun, More Savings—If You Use It Right
Daylight saving time gives solar households more of what they need most: sunlight. But to turn that sunlight into savings, it’s not just about having panels—it’s about using them smartly.
At Spark Energy, we help you get the most out of your system with performance checks, battery upgrades, and tailored advice. Whether you’re looking to fine-tune your setup or considering a new install before summer, now’s the perfect time.
