Is Solar Panel Installation Worth Only In Summer?

Australia is renowned for its scorching summers, some of which can reach extremely high temperatures. Although there is plenty of sunshine during this time, it may have an impact on the efficiency of your solar power systems. This article explores what to expect from your solar system this summer.

Heat and power - Two separate things in solar panel installation

The photovoltaic effect is the method by which solar panels for home use the sun's rays to generate electricity. Nevertheless, solar panel efficiency decreases with rising temperatures. This is because heat reduces the panels' overall performance and voltage output, which reduces the amount of electricity produced. Get in touch with us to know more about our cost effective solar panel installation cost. The ideal temperature range for solar energy is usually 77°F (25°C) to 86°F (30°C). The exact panel you have will determine how much electricity they generate outside of this range. In different temperatures, different brands and models function slightly differently. For instance, REC Alpha Pure-R panels, one of the best solar panels, may function at temperatures as low as -40°C and as high as 85°C. Consult the manufacturer's datasheet to find out how your particular panels function at varying temperatures. Sunray Power offers the best solar panels australia. Contact us for a free consultation.

How will my solar system function when it gets hotter?

Cool weather is ideal for solar panel performance. They generate less electricity when they get hot. This can be attributed to their manufacturing process. Silicon is the material used to make most solar panels. The efficiency of silicon's ability to convert sunlight into electricity decreases with temperature. The phrase "temperature coefficient" is used by experts to characterise this phenomenon. For most solar panels, the output decreases with each degree Celsius above 25°C (77°F) by approximately 0.4%. The performance of solar panels is measured at 25°C and used to determine ratings. In regions with greater temperatures, such as Australia, where 50°C (122°F) is frequently reached, solar panels will not generate as much electricity as their rating indicates. When purchasing solar panels for a hot climate, two crucial numbers to take into account are:

• Temperature coefficient: This is the amount of power lost by the panel for each degree Celsius when it is heated over 25°C.
• NMOT: The predicted operating temperature of the panel under real-world conditions is indicated by the NOCT (Nominal Operating Cell Temperature) or NMOT (Nominal Module Operating Temperature).

Tips to reduce your power bill during summer

Summer brings sunshine, but also hotter temperatures. While your solar panels will still generate power, very hot weather can slightly reduce their efficiency. Here are some easy ways to get the most out of your solar panel installation this season:

Air conditioner:

The effectiveness of your air conditioning system is important to consider when trying to be comfortable in hot weather. For a performance improvement, older split systems might only need a new filter, while some can need a total rebuild. It's crucial to remember that continuous air conditioning use, particularly for whole homes, may use more energy than other options. Aim to cool just the rooms you're using if you must use an air conditioner. Here are some tips to maximize your air conditioning's efficiency:

• If you have solar panels, run your system throughout the day to maximize the use of renewable energy.
• When the sun is at its strongest, draw the blinds closed to keep heat out of your house. To stop cold air from escaping, seal any drafts around doors and windows.
• Set the temperature range on your thermostat to 25°C to 27°C. This configuration keeps you comfortable and lets your system function well.

Usage of energy:

Take into account carefully when to use your energy. Usually late at night or early in the morning, off-peak hours are when most electricity providers provide cheaper rates. Just scheduling the operation of your air conditioner to occur during these off-peak times will result in significant electricity bill savings.

Enhancing home insulation:

Your air conditioning unit's workload can be greatly decreased with proper home insulation. You can prevent hot air from the outside from creeping into your home by sealing any openings or crevices around windows, doors, and other areas. Furthermore, making sure your crawl spaces, attic, and walls are sufficiently insulated helps to create a barrier that keeps cold air in and heat out. This dual strategy extends the life of your air conditioner and lowers your energy costs by generating a more constant and comfortable indoor temperature. It also permits your air conditioner to run less frequently and for shorter periods of time.

Wrapping up

It's normal to see a modest drop in your solar system's power output under extremely hot conditions. Nevertheless, your solar panels will keep producing electricity and help meet your home's power requirements even on the warmest days.
