How to use this
- Click the manufacturer's datasheet/manual link for the product on your bid
- Compare nameplate efficiency, output power, temperature coefficient, warranty length
- Verify the bid uses the current model (not a 2-year-old version)
- Use the warranty terms in this datasheet, not what the salesperson tells you

What to look for in a datasheet
- STC vs PTC vs CEC ratings: STC is lab; PTC and CEC are real-world. Production estimates use one of these — check which.
- Temperature coefficient (% per °C): determines how much performance you lose in summer heat. Better panels are -0.30% to -0.34% per °C; budget panels are -0.40% or worse.
- Power output tolerance: +5/-0% is good; +5/+0 is better; +0/-3% is suspect.
- Annual degradation rate: 0.25-0.4% per year is premium; 0.5-0.7% is budget.
- Warranty length AND terms: "25-year warranty" can mean 80% retained capacity (budget) or 92% retained capacity (premium).
- UL listings: 1741 SB is current; older UL 1741 is being phased out for utility interconnection.
