Key Factors to Consider When Choosing Solar Panels
1. Efficiency: Why It Matters
Solar panel efficiency measures how much sunlight converts to electricity. Higher efficiency means:
- More power from limited space (critical for small roofs)
- Fewer panels needed for same output
- Better aesthetics (less roof coverage)
- Higher value for premium installations
Efficiency tiers for 2025:
- Premium (21%+): SunPower, REC, Panasonic
- Mid-range (19–21%): Q CELLS, Canadian Solar, Silfab
- Value (<19%): Mission Solar, budget brands
2. Temperature Coefficient
Panels lose efficiency as they heat up. Lower temperature coefficients (closer to zero) mean better performance on hot days:
| Brand | Temperature Coefficient | Performance at 95°F (vs. 77°F) |
|---|---|---|
| SunPower | -0.29%/°C | 96% of rated power |
| REC | -0.24%/°C | 97% of rated power |
| Panasonic | -0.26%/°C | 96.5% of rated power |
| Q CELLS | -0.34%/°C | 94% of rated power |
| Standard | -0.35 to -0.40%/°C | 92–94% of rated power |
3. Degradation Rate
All solar panels slowly lose efficiency over time. Lower degradation means more power decades from now:
- Premium brands: 0.25–0.30% annual loss (92% after 25 years)
- Standard brands: 0.50–0.70% annual loss (85–88% after 25 years)
4. Warranty Comparison
| Brand | Product Warranty | Performance Warranty | Year 25 Output |
|---|---|---|---|
| SunPower | 25 years | 25 years | 92% |
| REC | 25 years | 25 years | 92% |
| Panasonic | 25 years | 25 years | 92% |
| Q CELLS | 25 years | 25 years | 86% |
| Silfab | 25 years | 30 years | 87% |
| LG* | 25 years | 25 years | 90% |
*Honored by LG despite exit from manufacturing
5. Aesthetics: Panel Appearance
- All-black panels (most premium look) – SunPower, REC, Panasonic, Silfab
- Black frame with blue cells – Q CELLS, Canadian Solar
- Silver frame with blue cells – Budget options
- Low-profile mounting – Tesla (flush mount), SunPower InvisiMount

Frequently Asked Questions
How long do solar panels last?
Quality panels last 25–30+ years with gradual efficiency decline. Most warranties guarantee 80–92% output after 25 years .
Will solar work in cloudy states?
Yes—Germany leads the world in solar despite cloudy weather. Panels produce 10–25% of rated power in overcast conditions .
Can I go off-grid?
Possible but expensive—requires large battery banks and potentially backup generator. Most homes stay grid-tied for reliability and net metering benefits .
What size system do I need?
Check your annual kWh usage on electric bills. Divide by 1,200–1,500 (typical production per kW in your area) for rough system size .
Do I need to replace my roof first?
If your roof is over 10–15 years old, replace it before solar. Removing panels for roof replacement adds $3,000–$5,000+ later .
What happens during power outages?
Grid-tied systems without batteries shut down for safety. Only systems with batteries and islanding capability provide backup power .
Is Solar Worth It in 2025?
For most homeowners, solar panels offer compelling financial and environmental benefits:
Solar Makes Sense If:
- You own your home (not renting)
- Your roof has good sun exposure (south-facing preferred)
- You pay $100+ monthly for electricity
- Your state has net metering or strong incentives
- You plan to stay in your home 5–7+ years
Solar May Not Be Ideal If:
- Your roof is heavily shaded
- You have a new roof with 10+ years left (just wait)
- Electricity rates are very low in your area
- You plan to move within 3–5 years
- Your HOA has restrictive policies
Conclusion: Choosing Your Best Solar Panels
After comparing top options for 2025, here are our recommendations by priority:
