Another significant factor influencing the price is the type of solar cells utilized in the panel. Monocrystalline panels are typically more expensive than polycrystalline ones due to their higher efficiency and longer lifespan. Consumers need to evaluate their energy needs and budget before making a decision. While polycrystalline panels might be less expensive initially, they could potentially result in lower energy production over time, which could impact long-term savings on electricity bills.
The efficiency of photovoltaic cells has improved dramatically over the past few decades, thanks to advances in technology and materials
. The average efficiency of commercial solar panels has risen from around 15% in the early 2000s to over 22% today, with some cutting-edge models achieving efficiencies above 25%. This growth has made solar energy more viable for widespread use, reducing the cost per watt and making solar installations more accessible to consumers and businesses alike.
