Seasonal changes can affect the production level of your solar solution. Autumn has been said to be the best season for solar! Keep reading to find out why Autumn is a solar systems best friend, and how you can best utilize your solar investment during the season.

Heat and Solar Panels

Many believe that the sunnier it is, the more energy their solar panels will produce. This is a common misconception. Hot weather can actually decrease the efficacy of solar panels. As the panels themselves heat-up, the energy output is reduced making them overall less efficient then when they are cooler.

The ideal temperature for solar panels is 25 degrees Celsius. According to data from the National Centers for Environmental Information (NOAA) the average temperature for March is 25° in Bendigo, making it the ideal time for local residents to produce as much solar power as possible.

Best Practices for Autumn Solar Usage

Fewer Daylight Hours

Numerous appliances can be set to running timers and many solar owners use this functionality to load-shift their peak energy usage to optimal solar production hours (typically between 10am-3pm).

Daylight savings ends on Sunday the 3rd of April in the middle of the Autumn season in Victoria and it is important that if you are using timers for your appliances you move the timers in-line with new optimal solar production hours.


Reflect on Your Summer Bill

Have a look at your summer electricity bill and consider looking at other power providers for better rates. Solar Analytics has a wonderful feature called Plan Optimiser that takes all of the thinking out of plan comparison for you.

Plan Optimiser uses your actual solar and household energy data to compare the available energy plans on the market and automatically find the best plan for you. If you are an existing Solar Analytics customer this feature will be available in your app.


Service Your Heating

Autumn is the ideal time to prep your home for heating in preparation for the very cool winter months. Depending on your heating system, it is well worth booking in a service.

Many homeowners will neglect maintenance on their heaters until winter, resulting in a breakdown in the cold season when it is really vital to have heating or having their systems run at a less-than-optimal capacity using excess energy during periods where they are used the most. Systems that aren’t tuned up will waste energy and increase your energy bill.


Consider Swapping to More Energy Efficient Lighting

Installing LED bulbs is a great way to reduce excess energy consumption, especially as daylight savings ends and reduced daylight hours increases the need for indoor lighting. LED light bulbs can last 100 times longer than a standard light bulb and use much less power.

The average household can expect to save $650 over 10 years of their electricity bill if they replace 10 halogen light bulbs with LEDs.


Heat your Home Efficiently

Did you know that every degree you increase your heating or cooling increases your energy usage by approx. 5% to 10%? Try to keep your thermostat to a steady temperature between 18°C to 20°C and avoid regularly switching your heating on and off again.

Keep draughts to a minimum by sealing up any gaps at the bases of your doors or around windows and close your curtains early in the evening to keep in the day’s warmth.
