Understanding Solar Panel Efficiency

What Is Efficiency?

Efficiency measures how much sunlight a panel converts to electricity. Higher efficiency means:

• More power from same roof space
• Better for limited roof area
• Higher cost per watt

Efficiency Ranges

• Best for: Limited roof space, maximum production

High Tier (21-22%):

• LG, REC, Panasonic, Canadian Solar, Jinko
• Best for: Most homeowners (good balance)

Standard Tier (20-21%):

• Q Cells, Trina, LONGi, Silfab
• Best for: Adequate roof space, budget-conscious

Budget Tier (<20%):
