4.Cons of Flexible Solar Panels

Flexible solar panels, despite their various benefits, have several drawbacks. They exhibit lower efficiency rates, endure for a shorter period of time, and incur greater expenses per watt when contrasted with their rigid counterparts.

Understanding these shortcomings is crucial when determining if flexible solar panels are the appropriate choice for meeting your energy requirements.

Lower Efficiency

Typically, the efficiency ratings of flexible solar panels fall within the range of 15-18%, which is lower than what rigid solar panels offer. These flexible panels are tailored for modest power production, with outputs usually ranging from 50 to 300 watts, rendering them less suitable for tasks requiring a lot of energy. The methods used to mount these flexible units can cause an accumulation of heat that may decrease their operational efficiency.

Consequently, when compared to traditional rigid solar panels, these flexible variants exhibit reduced rates in converting sunlight into usable energy.

Shorter Lifespan

The expected lifespan of flexible solar panels is considerably less than their rigid counterparts, posing a significant downside. These flexible panels typically endure for 5 to 15 years due to the thinner silicone and plastic materials from which they are made, impacting their sustainability over time.

Reflective of their shorter anticipated longevity, warranties provided for these flexible solar panels usually extend up to five years.

Higher Cost per Watt

Flexible solar panels come with a higher price tag per watt than their rigid counterparts, rendering them less cost-effective for substantial energy requirements. The elevated cost stems from the sophisticated materials and complex production methods necessary to create these flexible panels.

For individuals or entities with significant energy needs, this increased cost per watt associated with flexible solar panels can be a considerable disadvantage.
