5. PERFORMANCE ANALYSIS

An evaluation of performance metrics for plastic solar panels reveals several critical factors that determine their efficiency and suitability for various applications. Power conversion efficiency, resilience against environmental factors, and temperature coefficient are several essential aspects.

Power conversion efficiency refers to the ratio of electrical output to the incident solar power and is a primary indicator of the effectiveness of any photovoltaic technology. While conventional silicon solar panels can achieve efficiencies exceeding 20%, plastic counterparts currently reach about 10-15%. However, ongoing research continues to strive for improvements in polymer formulations that may push these figures higher.

Resilience against environmental factors such as moisture, UV radiation, and temperature oscillation is essential for determining the lifespan and reliability of any solar panel solution. While polymers are generally resistant to corrosion and have good mechanical flexibility, they may degrade more rapidly under sustained exposure to harsh environmental conditions compared to silicon panels. Thus, developing protective coatings or enhancing the durability of the polymers is an area of active investigation.
