Solar panels work well in winter and can even perform more efficiently in cold temperatures. REC Alpha panels are built to withstand harsh weather conditions like heavy snow and strong winds, making them ideal for winter climates. While shorter daylight hours can slightly reduce output, they continue generating electricity as long as there's sunlight.
Solar panels generally last over 30 years or even longer with proper maintenance. REC Alpha panels, for example, come with a 25-year warranty, guaranteeing reliable performance for decades. While their efficiency may decrease a bit over time, they typically still produce about 90-94% of their original power after 25 years.
Solar panels require very little maintenance, making them an attractive, hassle-free investment. Since they have no moving parts, there’s minimal risk of mechanical failure. In most cases, routine rain is enough to keep them clean. However, in areas with heavy dust, pollen, or snowfall, occasional cleaning may help maintain peak efficiency.
Most solar panel systems are monitored remotely, alerting homeowners to any performance issues. Additionally, modern panels come with long-term warranties (often 25 years or more), ensuring their durability and performance over time. If your system includes a battery or inverter, periodic inspections may be recommended, but overall, solar panels are designed to work efficiently with little to no intervention.
