What to Consider When Choosing

#

Efficiency vs Cost Higher efficiency panels cost more but generate more electricity per square metre. If roof space is limited, the premium may be worthwhile.

#

Warranty Terms Look for both performance and product warranties. Performance warranties guarantee minimum output (typically 80-85% after 25 years), while product warranties cover defects.

#

Temperature Coefficient UK summers are getting warmer. Panels with lower temperature coefficients perform better in heat. Look for -0.29%/°C or lower.

#

Degradation Rate All panels lose efficiency over time. Premium panels typically degrade at 0.25-0.3% per year, budget options at 0.5% or more.

Our Recommendation

For most UK homeowners, we recommend mid-range panels from JA Solar or Jinko. They offer excellent efficiency, strong warranties, and represent the best value for money. The premium paid for top-tier brands like SunPower is only justified if you have very limited roof space or plan to stay in your home for 30+ years.
