Solar Energy Project Feasibility

Prospecting & Resource Assessment

The "fuel" of a solar project is the most critical factor driving its commercial success or failure. Where is irradiance strongest? How much year-to-year power variability is expected? What are the exceedance values at the site? Without answers to these questions, it is impossible to assess a project's feasibility or manage your exposure to risk. 3TIER accurately answers these questions anywhere on Earth.

Quickly Explore Solar Resources Around the World

Save time and money by targeting the best locations for solar energy projects and infrastructure. 3TIER lets you quickly explore any location around the world directly from your computer. Now you can avoid problem sites and separate successful projects from marginal ones earlier in the process. Our on-demand, initial solar resource assessments are based on a consistent, global dataset so you can compare sites with confidence.

The First and Only Advanced Solar Dataset with Global Coverage

Spatial resolution of ~3 km
13+ years of hourly GHI, DNI, and DIF
Based on over a decade of satellite data with continual updates
Validated and developed using widely recognized datasets worldwide
Multiple delivery formats

Maximize Accuracy With State-of-the-Art Science

Direct measurements are the best way to record actual solar conditions and unique, localized effects at a site. However, it takes 10+ years to capture climatic variability, which can make or break a project financially, and few measurement campaigns have records extending that far back in time. To mitigate this risk, 3TIER uses on-site measurements to correct our long-term satellite data with advanced statistical techniques. The result is significantly reduced uncertainty about future project performance and the bankable production estimates required to secure project financing.

A Trusted Name in Solar

3TIER has completed solar resource assessment in very challenging climates and for several of the largest utility-scale projects currently in development around the world. In addition, 3TIER provided resource assessments for the majority of the shortlisted project applications for the Australian Government's Solar Flagships program.
