Financiers need to have confidence in a solar project's ability to service debt from month-to-month and year-to-year.
TMY datasets exclude critical information that masks the financial risk of climate variability. Using them to determine production estimates could prevent you from getting financed or put your project in danger of default.
But don't just take our word for it:
"Simple TMY formats are not sufficient for building major projects."
- Standard and Poor’s Solar Credit Weekly
"TMY should not be used to predict weather for a particular period of time, nor are they an appropriate basis for evaluating real-time energy production…"
- NREL’s User Manual for TMY3 Datasets
