The use of on-site meteorological data to create “tuned” satellite weather files for solar energy assessments has become more common as projects have ballooned in capacity. On-site data intuitively provides confidence in the local irradiance. But does that confidence hold up to rigorous statistical evaluation? In this webinar, DNV’s experts will discuss methodology to leverage on-site measurements for the most accurate weather file selection while reducing overall uncertainty in the energy assessment process, covering:
- The hidden pitfalls of defaulting to on-site measurements as the single source of truth for irradiance.
- Advanced statistical methods for minimizing overall uncertainty by using multiple available weather files.
- The value of on-site measurements when utilized appropriately to minimize uncertainty and boost project economics.
