Understanding solar efficiency in summer

Solar panels are designed to convert sunlight into energy effectively, but their performance can vary with temperature changes. While sunny days provide ample light, excessively high temperatures can reduce panel efficiency due to thermal stress. This phenomenon, known as the “temperature coefficient,” highlights the need to optimise solar power in hot weather.

Key summer solar tips for maximum efficiency

Implementing practical strategies can ensure that your solar system performs well during the hottest months. Below are expert-recommended summer solar tips:

1. Regular cleaning of solar panels

Regular cleaning of solar panels can significantly improve performance.  Dust, bird droppings, and debris can accumulate on solar panels, blocking sunlight and reducing efficiency. In summer, these issues may intensify due to dry, windy conditions.

  • Tip: Use water and a soft brush, or hire professionals for thorough cleaning. Clean panels early or late in the evening to avoid rapid evaporation and streaks.

2. Ensure proper ventilation around panels

Solar panels work best when they remain cool. Stagnant heat can reduce their efficiency, especially in hot weather.

  • Tip: Install solar panels with an elevated racking system to allow air circulation underneath. This cooling effect mitigates heat buildup and ensures better performance.

3. Optimise solar panel orientation and tilt

Solar panels positioned at the wrong angle may not capture the maximum sunlight during summer.

  • Tip:
    • North-facing solar panels: In Australia, north-facing solar panels, including summer, receive the most sunlight throughout the year. Ensure your panels are optimally oriented to maximise sun exposure.
    • Tilt angle: The ideal tilt angle for solar panels can vary depending on your location. Consult with a solar professional to determine the optimal angle for your specific region.

4. Smart energy usage

By adjusting your energy consumption habits, you can better utilise the energy generated by your solar system. Consider using energy-efficient appliances, scheduling laundry and dishwashing during off-peak hours, and optimising your air conditioning settings.

  • Tip: Investing and upgrading energy-efficient appliances is a sensible way to save electricity costs and lessen environmental impact.

5. Understand your solar feed-in tariff

Familiarise yourself with your solar feed-in tariff, which determines the rate at which your electricity retailer pays you for excess solar energy exported to the grid.

  • Tip: Discover your best energy deal with Energy Matters. You can quickly compare top offers in your area and find the best deal for your energy needs. Our advanced tool draws data from a trusted network of retailers, so you can easily evaluate options and choose a plan that gives you more power and better savings on electricity and gas bills. 

6. Monitor and maintain your solar system

Real-time solar system monitoring can help you identify inefficiencies caused by wear and tear, weather conditions, or shading.

  • Tip: Use energy monitoring apps to track performance and schedule professional inspections annually to maintain top-notch solar power in hot weather.

7. Consider solar battery storage

A solar battery storage system can store excess solar energy generated during the day during peak demand periods and summer hours. This can help you reduce reliance on grid power and maximise the benefits of your solar system.

  • Tip: Use Energy Matters’ easy-to-use solar power and battery storage calculator to determine the size of your solar system with storage! Our solar calculator will generate performance information and potential savings.

Advantages of solar battery systems in summer

  • Increased self-consumption: Store surplus solar energy instead of exporting it to the grid.
  • Energy independence: Reduce reliance on the grid during peak usage hours.
  • Uninterrupted power supply: Protect your home from blackouts during extreme weather events.

8. Invest in high-quality solar inverters

Solar inverters are the backbone of your solar system, converting direct current (DC) electricity to usable alternating current (AC). An efficient or overheating inverter can help performance.

  • Tip: Upgrade to a modern, high-efficiency solar inverter to maximise energy conversion. Place inverters in shaded, ventilated areas to prevent overheating.

Protecting solar panels from extreme heat

High temperatures are a double-edged sword for solar panels. While sunlight is essential, prolonged exposure to extreme heat can decrease efficiency. Here are some ways to mitigate this issue:

Install heat-resistant panels

Some solar panel models are specifically designed to perform better in hot climates, offering a lower temperature coefficient.

  • Tip: Choose heat-resistant solar panels with proven durability for Australian summers.

Use reflective paints or roof coatings

Roofs that reflect rather than absorb heat can reduce the temperature around your solar panels.

  • Tip: Consider reflective roof paints or coatings to keep temperatures in check and improve solar efficiency in summer.

Shade your solar inverter

Solar inverters are particularly susceptible to overheating. If they malfunction, your entire system could stop working temporarily.

  • Tip: Install solar inverters under a shaded area or protective cover to shield them from direct sunlight
