Which is more efficient, Mission Solar or Silfab Solar?
Silfab Solar is more efficient, converting up to 22% of sunlight into electricity versus 21.3% for Mission 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, Mission Solar or Silfab Solar?
Mission Solar is the lower-cost option, starting near $0.60 per watt before installation. Mission Solar ranges $0.60–$1.00/W and Silfab Solar ranges $0.70–$1.35/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?
Silfab 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 Mission Solar or Silfab Solar panel should you choose?
- Small or shaded roof: Silfab Solar — higher efficiency fits more power in less space.
- Tight budget / large roof: Mission Solar — lower price per watt wins when space isn't the constraint.
- Hot climate: Silfab Solar — better heat performance protects summer output.
- Longest protection: Silfab Solar — 25-year product warranty.
