7 Tips & Strategies to Enhance Solar Panel Efficiency

Solar Panel Efficiency Tips & Strategies

1. Purchase the Right Solar Panels

For solar panel efficiency, not all panels are equally efficient. There are three main types of solar panels: monocrystalline, polycrystalline, and thin film. 

  • Monocrystalline Solar Panels: Monocrystalline solar panels are well-known for their high efficiency, longevity, and output power. This solar system price is the most expensive in comparison with others. These streamlined and small-footprint panels have a life expectancy of up to 25 years and an efficiency rate of 15% to 24%, outweighing the costs in the long run. On the other side, colder climates could affect how well they work.
  • Polycrystalline Solar Panels:  Polycrystalline solar system price are less expensive. However, they have lower efficiency and power production. Compared to monocrystalline solar panels, these panels require more roof space and have a blue tint that might not match your home’s interior design. However, they may provide electricity for 25 to 35 years and perform well in drier climates.
  • Thin-Film Solar Panels: Thin-film solar panels offer the least efficiency and power production but are the most cost-effective solar system price. They perform well in small-scale systems and are unaffected by heat or shade. However, they are the least efficient and produce the least amount of electricity, and they only last 10 to 20 years.

For Homes & Businesses with no space constraints, polycrystalline & monocrystalline panels are both equally good options and provide a good return on investment

2. Do not Install Solar Panels in Shaded Areas

Shading can significantly impact solar panel efficiency, reducing up to 40% of the potential solar generation. 

  • Impact: The impact of shading can vary based on the location and time of day. Shading on even a single panel can cause a reduction in the output of the entire solar system, reducing its efficiency. It can also cause hotspots that may damage the panels over time.
  • Solution: You can opt for advanced panel technologies, like microinverters or DC optimizers, to help the system adjust to partial shading. Additionally, installing panels in an ideal setting can help maximize solar panel efficiency. Regular maintenance and cleaning of the panels are also essential for optimal performance.

At Freyr Energy, we do a detailed shadow analysis and suggest the placement of the solar panel array in such a way that no shadow falls on the panels.

3. Solar Panel Orientation

When it comes to finding the best solar panel in India, solar panel orientation is also a crucial factor to consider. Essentially, solar panel orientation refers to the direction in which the panels are facing, with the true north being the reference point instead of the magnetic north pole.

It will ensure that your panels get the most exposure to sunlight throughout the day, resulting in maximum electricity production.

On the other hand, for homes located south of the equator, the ideal orientation is facing true north. This orientation will also provide the best exposure time to the sun, allowing your solar system to generate the most energy possible.

If you’re installing solar panels for your home in India, it’s best to have them facing south. It allows the panels to capture the most solar radiation, resulting in maximum solar generation for your household.
