Choosing locations with high solar potential and low risk
Ideal sites for solar concentration have abundant direct sunlight, low cloud cover, flat terrain, and reasonable proximity to transmission and water or cooling resources. Local regulations and land costs also influence site suitability.
Key site attributes:
- High DNI: deserts and high-altitude plains with clear skies offer the best direct beam resource.
- Low cloudiness and low aerosol loading: less haze and pollution increase effective DNI.
- Land availability: large, contiguous parcels with suitable terrain reduce construction complexity.
- Grid access: nearby transmission capacity or the ability to build interconnection keeps costs manageable.
Additional considerations:
- Water availability for cooling (or dry-cooling alternatives to conserve water).
- Environmental impact assessments for local habitats and wildlife.
- Proximity to demand centers or industrial users for process heat applications.
Site selection combines solar resource analysis, engineering feasibility, environmental review, and economic assessment to select the most viable locations.
