Which is more efficient, Canadian Solar or Panasonic?

Canadian Solar is more efficient, converting up to 23.3% of sunlight into electricity versus 22.2% for Panasonic. Higher efficiency produces more watts per square foot, so it matters most on small or partially shaded roofs. On a large, unshaded roof the difference is minor — you can add a panel or two to match output.

Which is cheaper, Canadian Solar or Panasonic?

Canadian Solar is the lower-cost option, starting near $0.45 per watt before installation. Canadian Solar ranges $0.45–$1.25/W and Panasonic ranges $0.95–$1.55/W. On a typical 6 kW system that price gap works out to a few hundred to a few thousand dollars before incentives like the 30% federal tax credit.

Which performs better in hot weather?

Both panels have similar temperature coefficients, so they lose output at about the same rate in heat. In hot-sun states like Arizona, Texas, and Florida, a better temperature coefficient can mean a few extra percent of summer production.

Which Canadian Solar or Panasonic panel should you choose?

  • Small or shaded roof: Canadian Solar — higher efficiency fits more power in less space.
  • Tight budget / large roof: Canadian Solar — lower price per watt wins when space isn't the constraint.
  • Hot climate: either brand — better heat performance protects summer output.
  • Longest protection: either branda 25-year product warranty.
