Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Solar panels are 100% efficient | No solar panel is 100% efficient. The most efficient solar panels on the market have an efficiency rating of around 22-23%. This means that they can convert up to 23% of the sunlight that hits them into usable electricity. |
| Higher wattage equals higher efficiency | Wattage and efficiency are not directly related. A higher wattage simply means that a solar panel can produce more power, but it doesn’t necessarily mean that it’s more efficient at converting sunlight into electricity. Efficiency is measured as a percentage of how much sunlight is converted into usable energy, regardless of the size or wattage of the panel. |
| Solar panels lose their efficiency over time | While it’s true that all solar panels degrade over time, modern solar technology has greatly improved in terms of durability and longevity. Most reputable manufacturers offer warranties for their products which guarantee a certain level of performance for up to 25 years or more. Proper maintenance and cleaning can also help extend the lifespan and maintain optimal performance levels. |
| All types/brands/models of solar panels have equal efficiency ratings | Different types/brands/models of solar panels have different efficiencies due to variations in materials used, manufacturing processes, and design features such as cell size and shape. It’s important to do research before purchasing a system to ensure you’re getting one with high-quality components from a reputable manufacturer. |
| Solar panel efficiency only matters if you live in sunny areas/climates | While it’s true that more sun exposure generally leads to better energy production from your system, even areas with less sunshine can still benefit from installing solar panels because they will still generate some amount of electricity during daylight hours (even on cloudy days). Additionally, many utility companies offer net metering programs which allow homeowners with excess energy production to sell back unused power to the grid, regardless of their location. |
