Early solar cells had an efficiency of less than 5%, which meant they could only convert a small portion of sunlight into usable electricity. Over the years, however, innovations in material science and manufacturing processes have led to continuous improvements in solar panel efficiency.
In 2025, the average efficiency of solar panels for home installations ranges from 18% to 22%, with some premium models reaching even higher efficiencies. The cost of solar panels has decreased dramatically over the past few decades, making solar energy more accessible than ever.
The difference between an average panel and a highly efficient one can mean fitting a complete solar energy system on a smaller roof—or generating substantially more power from the space you have. Today, most panels are at least 20% efficient, but the best ones convert over 22% of the sun''s energy into electricity.
The most efficient solar panel available for homes today is Maxeon’s 440-watt panel at 22.8% efficiency. Solar panel efficiency is the percentage of incoming sunlight that a single solar panel can convert into electricity. Maxeon, Qcells, Solarever USA, Canadian Solar, and REC currently offer the most efficient solar panels on EnergySage.
Our home solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment in Polish conditions. All systems include comprehensive monitoring and control with remote management capabilities.
