Which is more efficient, JinkoSolar or Trina Solar?
JinkoSolar is more efficient, converting up to 22.65% of sunlight into electricity versus 22.5% for Trina Solar. 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, JinkoSolar or Trina Solar?
Both brands start near $0.45 per watt before installation. JinkoSolar ranges $0.45–$1.00/W and Trina Solar ranges $0.45–$0.95/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?
Trina Solar performs better in heat, with a temperature coefficient closer to zero — it loses less output as panel temperature climbs. In hot-sun states like Arizona, Texas, and Florida, a better temperature coefficient can mean a few extra percent of summer production.
Which JinkoSolar or Trina Solar panel should you choose?
- Small or shaded roof: JinkoSolar — higher efficiency fits more power in less space.
- Tight budget / large roof: either brand — lower price per watt wins when space isn't the constraint.
- Hot climate: Trina Solar — better heat performance protects summer output.
- Longest protection: either brand — a 15-year product warranty.
