Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| South-facing solar panels are always better than north-facing ones. | While south-facing solar panels may receive more direct sunlight, the orientation of your home and shading from nearby trees or buildings can affect their efficiency. North-facing panels can still generate a significant amount of energy, especially in areas with high levels of diffuse light. It’s important to consider factors such as roof pitch and shade when deciding on panel placement. |
| Solar panels should only be installed on roofs that face south. | While south-facing roofs are ideal for maximizing solar energy production, east- and west-facing roofs can also work well depending on your location and energy needs. In some cases, installing panels on multiple roof faces or using ground-mounted systems may be necessary to achieve optimal performance. A professional installer can help determine the best placement for your specific situation. |
| The angle of the solar panel doesn’t matter as long as it faces the right direction. | The angle at which a solar panel is mounted affects its ability to capture sunlight throughout the day and year-round. Panels should generally be tilted at an angle equal to your latitude plus 15 degrees in winter months (to maximize exposure to low-angle winter sun) and minus 15 degrees in summer months (to avoid overheating). However, this varies based on location and other factors such as shading patterns, so consulting with an expert is recommended for proper installation. |
| Solar power isn’t worth investing in if you live in a cloudy area or have limited sun exposure during certain times of year. | Even areas with lower levels of direct sunlight can benefit from solar power due to advances in technology that allow for greater efficiency under diffused light conditions. Additionally, many utility companies offer net metering programs that credit homeowners for excess electricity generated by their systems even during periods of low output. |
