Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| East-facing roofs are better for solar panels because they receive more sunlight in the morning. | While it is true that east-facing roofs receive more sunlight in the morning, west-facing roofs actually produce more electricity overall because they receive sunlight during peak hours when energy demand is highest. The ideal orientation of solar panels depends on various factors such as location, climate, and shading. |
| West-facing roofs are not suitable for solar panels because they do not receive enough sunlight. | This is a common misconception as west-facing roofs can actually be advantageous for solar panel installation due to their ability to capture afternoon sun which coincides with peak energy demand times. In fact, some studies have shown that west-facing systems can generate up to 20% more electricity than south or east facing systems depending on location and other factors. |
| Solar panels should always face south for maximum efficiency. | While south facing rooftops may be optimal in certain locations, this does not hold true universally across all regions and climates. Factors like latitude, weather patterns and shading must also be considered before determining the best orientation of your solar panel system. |
| It doesn’t matter where you install your solar panels as long as there’s sunshine. | Proper placement of your solar panel system plays a crucial role in its performance and longevity over time; therefore it’s important to consider several factors including roof pitch angle, directionality (east vs west), shade coverage from trees/buildings etc., local weather conditions (cloud cover/rainfall) among others before installing them anywhere. |
