Introduction
Investing in solar energy is a long-term commitment. If you’re considering making the switch, one of your first questions is likely: “How long do solar panels last?” At Arise Solar, we understand that durability and dependability are essential, especially when choosing a solar panel installation in Delaware. In this comprehensive guide, we’ll explore the lifespan of solar panels, explain what affects their longevity, and showcase why Arise Solar residential services offer exceptional quality and reliability. Learn why choosing us ensures value, performance, and peace of mind.
1. What Affects Solar Panel Lifespan?
Quality of Panels
High-grade panels from reputable manufacturers tend to last 25 to 30 years or more. We at Arise Solar use only premium panels known for their durable materials and build quality.
Manufacturer Warranty
Most quality solar panels come with a performance warranty of 25 years. Arise Solar goes further, only partnering with manufacturers who guarantee at least 80% efficiency after that warranty period. Rest assured, our installations match those long-term protections.
Installation & Component Quality
A quality Solar panel installation in Delaware involves more than just panels — it includes racking, wiring, inverters, and labor. Incorrect installation can lead to durability issues. Our certified technicians ensure secure mounting, sealing against moisture, and correct wiring, supported by rigorous safety standards.
Environmental Wear & Tear
Delaware's climate can be challenging—hot summers, humid springs, and occasional hailstorms. Over time, UV exposure, thermal expansion, and precipitation cause degradation. Our chosen panels are designed to withstand these weather patterns.
Regular Maintenance
Though mostly maintenance-free, solar systems benefit from periodic checks and cleaning. Arise Solar provides comprehensive maintenance packages and remote monitoring to detect issues early.
2. Typical Lifespan of Solar Panels
Manufacturer Claims
- Polycrystalline or Monocrystalline Si Panels: Typically guaranteed for 25 years of power output.
- Efficiency Decline: Starting around 0.5% per year, after 25 years, output may reach ~87%. High-quality panels often perform even better than rated.
Real-World Case Studies
Independent reviews confirm panels retaining >85% of rated capacity after 30 years —testament to technological progress and Arise Solar residential services ensuring proper installation.
3. What Happens After 25–30 Years?
Continued Functionality
Yes—your system still generates electricity! Even at 80% efficiency, it remains valuable. For decades to come, you’ll enjoy ongoing savings and reduced energy expenses.
Upgrading Inverters
While panels last decades, inverters typically have shorter lifespans (~10–15 years). Arise Solar offers upgrade services to swap older inverters with modern, high-efficiency ones, sustaining system longevity.
Repowering & Expansion
You may replace older panels with new, higher-efficiency models later. Other technologies, like microinverters or battery backups, can also enhance system performance.
