Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Bigger solar panels are always better. | The size of the solar panel should be determined by the energy needs of the household or business. A larger panel may not necessarily be more efficient if it produces more energy than needed, leading to wasted resources and higher costs. |
| Small solar panels are only suitable for small households or businesses. | The size of a solar panel is not an indicator of its efficiency or suitability for a particular property. Small panels can still generate significant amounts of electricity, especially when combined with other renewable energy sources such as wind turbines or hydroelectric power systems. |
| Large solar panels require more maintenance and upkeep than smaller ones. | Maintenance requirements depend on factors such as weather conditions, location, and quality of materials used in manufacturing the panel rather than its size alone. Proper installation and regular cleaning can help ensure that any type of solar panel operates efficiently over time without requiring excessive maintenance efforts from owners or operators alike. |
| Smaller solar panels have lower output capacity compared to larger ones. | While it’s true that larger panels generally produce more electricity per unit area than smaller ones do, this doesn’t mean that smaller units cannot meet your energy needs effectively; you just need to install enough small-sized units to match your required output capacity instead. |
| Larger Solar Panels Are More Expensive Than Smaller Ones. | This isn’t always true since prices vary depending on several factors like brand name, technology used in production (monocrystalline vs polycrystalline), warranty period offered by manufacturers among others which means some large-sized models could cost less while some small-sized models could cost much higher based on these variables mentioned above. |
