What’s The Role of a Solar Panel?

Solar panel (aka PV modules) is an extremely important part of any Solar PV System. It’s what creates your own electricity and without them, you would have nothing!

Solar panel layers

Solar panels convert sunlight into electricity through a process called the photovoltaic effect:

How solar Panels Work
  1. Sunlight Absorption: Solar panels absorb photons (light particles) from the sun.
  2. Electron Excitation: Photons transfer energy to electrons in the panel’s semiconductor material, causing them to move and generate a flow of direct current (DC) electricity.
  3. Inverter Conversion: The DC electricity is converted into usable alternating current (AC) electricity by an inverter.

How to Choose Wisely

In our solar panel guide, we emphasise reliability over short-term gains. Many solar companies offer panels that are readily available at competitive prices. However, not all suppliers maintain the same standards of durability and performance.

Unfortunately, the solar market can attract “cheap” operators and companies that may disappear soon after installation, leaving customers without support or recourse. To safeguard your investment, it’s crucial to partner with endorsed suppliers who prioritize:

  • Quality Products: Endorsed suppliers offer solar panels that have undergone rigorous testing and have proven reliability even in harsh Australian environments.
  • Long-Term Performance: These suppliers prioritize products that have demonstrated consistent performance over time, ensuring durability and efficiency throughout the lifespan of your solar system.

By choosing endorsed suppliers highlighted in our solar panel guide, you can be confident that you’re investing in solar panels that meet high standards of quality and longevity, providing peace of mind for years to come.

Key Considerations for Choosing Solar Panels

The type and brand of panel manufacturer that installation companies offer, can tell you a lot about the sort of business they are. Do they use well-established, tried and tested brands, with a long trading history behind them? Or are they using one of the new ‘no name’ solar panels that invariable pop up and then disappear just as quickly, leaving consumers with nowhere to go should they have any warranty claims in the future?

1. Solar Panel Efficiency

Solar panel efficiency refers to the ability of a solar panel to convert sunlight into usable electricity. This efficiency is measured as a percentage of the sunlight that strikes the panel and is converted into electrical energy. For example, a solar panel with 20% efficiency converts 20% of the sunlight it receives into electricity. Currently, most solar panels on the market offer efficiencies ranging from 20% to 23%.

Key Points:

  • Higher Efficiency, Higher Output: Panels with higher efficiency can produce more electricity per square meter, potentially reducing the number of panels needed to meet energy requirements.
  • Cost Consideration: Higher-efficiency panels often come at a higher cost upfront. However, they may result in long-term savings due to their ability to generate more electricity efficiently.
  • Other Influencing Factors: Solar panel efficiency can be influenced by factors like panel orientation, sunlight exposure, and temperature. While efficiency is important, it’s not the sole factor determining panel performance.

Choosing the Right Efficiency:

  • Efficiency above 20% is generally considered effective for most applications. Factors such as system design, installation quality, and local climate should also be considered when selecting solar panels.

Understanding solar panel efficiency helps in making informed decisions about your solar energy system, balancing cost, performance, and overall energy needs effectively.

2. Solar Panel Specifications

Each solar panel comes with specific technical details that describe its performance and characteristics, crucial for choosing the right panel for your needs.

Solar Panel Specifications

Key Specifications of Solar Panels Explained :

  • Wattage (Power Output): Indicates the amount of power a solar panel can produce under standard conditions, measured in watts (W) or kilowatts (kW)
  • N-Type or P-Type Solar Panels: N-Type panels use premium semiconductor materials for better performance and durability but come at a higher cost. P-Type panels are more cost-effective but may degrade faster in later years.
  • Mono-Facial or Bi-Facial Panels: Mono-Facial Panels: Capture sunlight on the front face only and suitable for standard rooftop installations. Bi-Facial Panels: Capture sunlight on both front and back sides, potentially benefiting from reflected light in certain environments.
  • Power Tolerance: Describes the range of power output variation under different conditions, expressed as a percentage (e.g., +/- 5%). The lower the % variation, the better.
  • Efficiency: Represents the percentage of sunlight converted into electricity. Higher efficiency panels generate more power in less space.
  • Voltage: Maximum voltage output of the panel when no load is connected. Critical for system design and component compatibility.
  • Current: Flow of electrical charge (measured in amps) that a solar panel can deliver, crucial for system design and performance.
  • Temperature Coefficient: Reflects how panel performance changes with temperature. Lower coefficients indicate better performance in hot weather.
  • Dimensions: Physical size of the panel, important for installation layout and required surface area.
