Choosing solar panels for home installation comes down to three things: efficiency, warranty, and installer availability. Premium panels aren’t always worth the premium — here’s how to pick the right panels for your situation in 2025.
What to Look for When Buying Solar Panels
Efficiency: The percentage of sunlight converted to electricity. Top panels: 22–23%. Standard panels: 19–21%. Higher efficiency matters most when roof space is limited — if you have room, more standard-efficiency panels often cost less than fewer premium ones for the same output.
Warranty: Two warranties to check — product warranty (10–25 years against defects) and performance warranty (typically guaranteeing 80–90% output at 25–30 years). Premium brands offer 25-year product warranties; budget brands often offer only 10 years.
Temperature coefficient: How much output drops per degree above 25°C. Lower is better. Quality panels: -0.26 to -0.30%/°C. Cheap panels: -0.35 to -0.45%/°C. This matters in hot climates.

How Many Panels Do You Need?
Rule of thumb: your annual kWh usage ÷ 1,200 (sun hours factor for most US locations) = kW of solar needed.
Example: 10,000 kWh/year ÷ 1,200 = 8.3 kW of panels = 20–22 panels at 400W each.
Your installer will calculate this precisely based on your location, roof orientation, and shading.
Conclusion
For most homeowners, the sweet spot is mid-range panels from Jinko, LONGi, or Qcells — 21–22% efficiency, 25-year warranty, and installers who stock them nationally. Premium panels make sense if you have very limited roof space. Budget panels are risky — a failed manufacturer voids warranties.
