Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Microinverters and power optimizers are the same thing. | While both technologies serve a similar purpose of optimizing solar panel performance, they function differently. Microinverters convert DC electricity from each individual solar panel into AC electricity for use in homes or businesses, while power optimizers optimize the DC output of each panel before sending it to a central inverter. |
| Power optimizers are always more efficient than microinverters. | The efficiency of both technologies depends on various factors such as shading, temperature, and system design. In some cases, microinverters may be more efficient than power optimizers due to their ability to handle varying levels of shading on different panels. It is important to consult with a professional installer to determine which technology is best suited for your specific situation. |
| Installing either microinverters or power optimizers will significantly increase my overall energy production. | While these technologies can improve the performance of individual panels by reducing losses due to shading or other issues, they do not necessarily increase overall energy production unless additional panels are added to the system as well. Additionally, proper installation and maintenance are crucial for optimal performance gains from these technologies. |
| I don’t need microinverters or power optimizers if my solar panels aren’t shaded at all times during the day. | Even if your solar panels receive direct sunlight throughout most of the day, there may still be periods where partial shading occurs due to trees or nearby buildings casting shadows over certain parts of your roof during peak sun hours (usually between 9am-3pm). This can result in significant losses in energy production without proper optimization technology installed. |
| Microinverters and power optimizers require extra maintenance compared to traditional string inverters. | While it is true that installing multiple microinverters/power optimizers requires more equipment than using one central string inverter for the entire system, this does not necessarily mean that maintenance requirements are higher. In fact, some microinverters and power optimizers come with monitoring software that can alert you to any issues before they become major problems. Additionally, because these technologies optimize each panel individually, they may actually reduce overall maintenance needs by preventing issues from spreading throughout the entire system. |
