Frequently Asked Questions
What solar panel efficiency do I need?
For most homes, 21-22% efficiency provides excellent performance at reasonable cost. Higher efficiency (23%+) is worth it if you have limited roof space or want maximum production. Homes with ample roof area can save money with 20-21% panels without sacrificing total output.
How long do solar panels really last?
Quality solar panels last 25-40 years with minimal degradation. Most panels retain 85-92% of their original output after 25 years. Premium panels like Maxeon maintain 88% output after 40 years. The panels will continue producing power beyond warranty periods, just at reduced efficiency.
Are the most expensive solar panels worth it?
Premium panels like Maxeon and Aiko offer superior efficiency, longer warranties, and slower degradation. They’re worth it if you have limited roof space, plan to stay in your home long-term, or prioritize maximum quality. Budget panels from Canadian Solar or Trina deliver excellent value for cost-conscious buyers.
Should I wait for better solar panel technology?
Solar technology improves incrementally, not dramatically. Today’s panels are excellent and will serve you well for decades. Waiting means losing years of energy savings and incentives. Current technology is mature and reliable—there’s no “revolutionary” breakthrough on the horizon worth delaying installation.
Do solar panels work in cold or cloudy climates?
Yes! Solar panels actually work more efficiently in cold temperatures. While cloudy weather reduces output, modern panels still produce significant power in diffuse light. Snowy regions often have excellent solar potential because panels generate power from reflected sunlight off snow, and cold temperatures improve efficiency.
What’s the difference between monocrystalline and polycrystalline?
Monocrystalline panels dominate the market in 2025 with higher efficiency (20-24%) and better performance. Polycrystalline panels are virtually obsolete, having been phased out due to lower efficiency (maxing at 18%). All major manufacturers now use monocrystalline technology.
