Compare the top commercial solar panel brands available in the UK. Expert analysis of efficiency, warranty, and value for money.
Choosing the right solar panels is crucial for maximizing your commercial installations performance and ROI. This guide compares the leading brands available in the UK market.
Top Tier 1 Manufacturers
Tier 1 manufacturers like Canadian Solar, Trina, JA Solar, and Longi dominate the commercial market. These brands offer the best balance of quality, warranty coverage, and value.
Premium Brands
For maximum efficiency, consider premium brands like SunPower, LG (while still available), or REC. These panels achieve 22%+ efficiency but command a price premium of 20-40%.
Efficiency Comparison
Standard commercial panels achieve 18-20% efficiency, while premium models reach 22-23%. Higher efficiency means more power from the same roof space, which is valuable when roof area is limited.
Warranty Comparison
Most Tier 1 manufacturers offer 25-year performance warranties guaranteeing 80-85% output. Product warranties typically range from 10-15 years.
Value for Money
For most commercial applications, Tier 1 panels offer the best value. The small efficiency gain from premium panels rarely justifies the additional cost unless roof space is severely limited.
