Sheerwater Solar’s Guide to Optimising Solar Panel Efficiency

12th Jun 2023


Harnessing solar energy is an endeavour that has become increasingly popular in recent years. With the advancements in solar technology and a global focus on sustainable energy sources, efficiency has become paramount. In this guide, we’ll explore the various methods to optimise the efficiency of your solar panels.

Positioning Your Solar Panels

  • Angle: The angle at which your solar panels are installed can have a direct impact on their efficiency. In the UK, the optimal angle is usually between 15 to 40 degrees.
    • South-facing: To capture the maximum amount of sunlight, panels should primarily face south.
  • Avoid Shading: Even a small shadow can significantly reduce a solar panel’s efficiency.
    • Periodically inspect for potential obstructions like growing trees or new buildings.
    • Use solar tracking systems to follow the sun’s trajectory throughout the day.

Proper Maintenance and Cleaning

  • Dust and Debris: Dirt can obstruct sunlight and diminish the output of the panels.
    • Regularly clean the surface of the panels with water and a soft brush.
    • In drier climates, consider automated cleaning systems.
  • Inspections: Regularly inspect panels for damage, wear, and tear.
    • Seek professional inspection annually for a thorough check-up.

Efficient Inverters

  • Inverter Role: The inverter is responsible for converting direct current (DC) to alternating current (AC). Its efficiency can directly impact the overall performance.
    • Invest in high-quality inverters.
    • Periodically review the inverter’s performance and ensure it’s not a bottleneck in your system.

Using Updated Technology

  • Monocrystalline Panels: These panels are known for their higher efficiency rates compared to polycrystalline.
  • Bifacial Solar Panels: These panels capture sunlight from both sides, increasing energy capture.
  • Anti-reflective Coatings: This technology can help panels absorb more sunlight, rather than reflect it.

Monitoring System Performance

  • Real-time Monitoring: Many systems offer real-time performance metrics.
    • This allows for immediate identification and rectification of issues.
  • Regular Analysis: Comparing performance data over time can highlight potential degradation or inefficiencies.

Optimising the efficiency of your solar panels is a combination of choosing the right technology, proper installation, regular maintenance, and continuous monitoring. Following these guidelines from Sheerwater Solar will ensure that you’re harnessing the maximum potential of the sun’s energy, leading to greater energy savings and a reduced carbon footprint.
