• Myth 1: Higher efficiency = better quality.
  → Build quality, warranties, and installer expertise matter just as much.
• Myth 2: Efficiency drops rapidly over time.
  → Modern Tier-1 panels degrade only 0.3–0.5% per year, still producing ~85% power after 25 years.
• Myth 3: Low-efficiency panels are useless.
  → They can still be the most cost-effective option where roof space is abundant.

Efficiency in Practice

• City Home, Los Angeles: Small roof → used 22% panels to cover all energy needs.
• Farmhouse, Texas: Big barn roof → picked 18% panels, saved $4,000 upfront, same yearly output.
• Off-Grid RV: Tiny roof → needed 23% panels to power appliances.

How to Boost Your Solar System

1. Clean panels often to let in more light.
2. Adjust tilt with the seasons if possible.
3. Use MPPT charge controllers for better energy capture.
4. Pair panels with lithium batteries to reduce storage loss.
5. Choose energy-efficient appliances to cut demand.

These steps can raise real-world output by 10–20%.
