Bankable energy production reports provide developers, investors, and lenders with a thorough, objective, and well-documented evaluation of the energy production potential of a wind or solar project. UL has authored reports for nearly 100,000 MW of wind and solar plants worldwide, and our reports are widely respected and accepted in the financial community.
Bankable reports for solar energy projects include the following:
- Site and project description – location, topography, land cover, technology description, and site visit record
- Review of resource monitoring campaign – status and history of resource monitoring stations, significant events observed or reported
- Data validation – description of data QC and validation method, period of record, problems or issues found, data substitution and reconstruction, overall data recovery percent
- Observed resource characteristics – summary of the solar resource based on site measurements; includes monthly and annual mean global horizontal irradiance (GHI) and direct and diffuse components if available, frequency distribution, diurnal variation, temperature patterns
- Long-term climate adjustment (MCP) – description of MCP method, reference stations or modeled data used, quality and consistency of reference data, long-term mean solar resource estimates
- Plant description – solar technology characteristics (efficiency, temperature response, other), layout
- Losses – enumeration and justification of losses by category; total estimated loss; categories include
- Module and plant availability; curtailments
- Electrical system losses
- Environmental losses due to, e.g., icing, soiling
- Uncertainties – explanation of uncertainties by category, including measurement errors, MCP, and losses.
