what is the best 100 watt solar panel

The best 100-watt solar panel depends on your specific needs, but efficiency, durability, and brand reliability are key factors. Monocrystalline panels generally outperform polycrystalline ones in power output and space efficiency, making them a top choice for most users. Look for models with high conversion rates, typically above 20%, to maximize energy production in limited space.

Another important consideration is build quality. Panels with sturdy aluminum frames, tempered glass, and weather-resistant coatings last longer, especially in harsh conditions. Renogy and Eco-Worthy are well-regarded brands that balance performance and affordability, while premium options like SunPower offer higher efficiency at a steeper price. Always check warranty terms—10 years or more is ideal—to ensure long-term value.
