FirstLook gives you and your financier a complete understanding of the immediate opportunity and the long-term value.
How accurate is FirstLook?
As part of our processing, we have compared our dataset to the existing NREL solar dataset for the continental United States. The 3TIER dataset is at higher spatial resolution and uses more satellite images to estimate hourly values of irradiance. This results in a bias that is similar to the NREL dataset, but with a Root Mean Squared Error (RMSE) that is appreciably smaller. The smaller RMSE implies that our dataset is more useful as a time series of values. In other words, our estimates of irradiance more closely track the observed values than the NREL estimates on an hour-by-hour basis.
Note that in some areas with highly reflective terrain, such as salt flats and some areas with permanent snow, the satellite algorithms have difficulty distinguishing clouds from the terrain. As a result, the cloudiness estimates in these areas are too high and the amount of global horizontal and direct normal radiation is underestimated. The diffuse radiation in these areas is overestimated. Known areas affected by these problems include the Bonneville salt flats on the Nevada-Utah border and the White Sands Missile Range in New Mexico.
What is Global Horizontal Irradiance?
The radiation reaching the earth's surface can be represented in a number of different ways. Global horizontal irradiance is the total amount of shortwave radiation received from above by a horizontal surface. This value is of particular interest to photovoltaic installations and includes both direct radiation and diffuse radiation.
Direct radiation is solar radiation that comes from the direction of the solar disk in the sky. Diffuse radiation is solar radiation that has been scattered by molecules and particles in the atmosphere and comes equally from all directions.
On a clear day, most of the solar radiation received by a horizontal surface will be direct radiation, while on a cloudy day most will be diffuse radiation.
What is Direct Normal Irradiance?
Direct Normal Irradiance (DNI) is the amount of solar radiation received per unit area by a surface that is always held perpendicular (normal) to the rays that come in a straight line from the direction of the solar disk in the sky. By keeping the surface normal to the incoming radiation, you maximize the amount of energy received. This quantity is of particular interest to concentrating solar installations and installations that track the position of the sun.
The FirstLook web tool no longer displays values for DNI. If you are interested in the DNI values for any location in the Western Hemisphere, please contact us.
What is Diffuse Horizontal Irradiance?
Diffuse Horizontal Irradiance is the amount of radiation received per unit area by a surface that is not subject to any shade or shadow and does not arrive on a direct path from the Sun.
The FirstLook web tool no longer displays values for Diffuse Horizontal Irradiance. If you are interested in the Diffuse Horizontal values for any location in the western hemisphere, please contact us.
What are the units of irradiance?
The amount of radiation received by the surface can be expressed as the amount of energy received by a unit of surface area per unit time. Note that energy per unit of time is called power.
The most common units for expressing the amount of solar radiation received by an object are Watts per square meter (W/m2) or kiloWatt-hours per square meter per day (kWh/m2/day).
The Watt is a unit of power, which is equal to one Joule per second. Somewhat confusingly, a kiloWatt-hour is a unit of energy, equal to exerting 1 kiloWatt of power (1000 Watts) during a one hour period. Consequently, 1 kWh is equal to 3.6 million Joules. It is the amount of energy needed to power one 100W light bulb for ten hours.
1 kWh/day is equal to 41.67 W.
What affects solar radiation at a given site?
The intensity of the solar radiation at a given location depends on your latitude, terrain, season, time of day and atmospheric conditions. For example, clouds, dust, and water vapor all affect the amount of radiation that reaches the surface at any given location.
The FirstLook irradiance estimates do not directly account for local shades and shadows, such as those caused by trees or buildings. As a result, you need to take local conditions into account when interpreting the FirstLook estimates.
Can I buy a GIS data layer of solar irradiance?
Yes. 3TIER provides GIS data layers for the entire western hemisphere or for any country within the hemisphere. We will provide three layers in total, one each for GHI, DNI and Diffuse Horizontal Irradiance. The data available for each of these layers are annual and monthly average values. Please contact us for pricing, which is dependent on the size of the region of interest.
What area does FirstLook cover?
3TIER’s solar dataset covers from 50S to 60N in latitude, and from 180W to 30W in longitude.
The reported values provide an estimate of the annual average amount of solar radiation in a 2 arc-minute by 2 arc-minute box surrounding your location, and the size of this area changes depending upon your latitude (2 arc-minutes of longitude is 3.7 km at the Equator and 2.6 km at 45N).
Currently, registered users get free annual solar Global Horizontal Irradiance (GHI) estimates for any location within those boundaries in the Western Hemisphere.
What solar value is shown on the map?
The FirstLook map interface shows values for Global Horizontal Irradiance (GHI). This map is derived from 3TIER’s solar dataset, the first comprehensive, contiguous, and high-resolution solar dataset of the Western Hemisphere. Additional information can be found in the ”Technical Details” section of this FAQ.
Why do we show a range?
Previously, the popup window in FirstLook showed only the average annual global horizontal irradiance. A confidence measure was shown separately along the bottom of the FirstLook window. The current version of FirstLook directly incorporates these confidence measures into the popup window. The new popup window shows a range of expected irradiance values, providing a more realistic assessment. We are 68% confident that the true irradiance for a given location falls inside the range shown.
Of course, the annual average isn’t the whole story. 3TIER’s FullView solutions provide a more detailed analysis. Please contact us for details.
When will you have data for other regions?
The solar irradiance map of the Western Hemisphere is part of 3TIER’s REMapping the WorldSM initiative. In the future, 3TIER will expand FirstLook to cover most global land surface areas.
Do you have data for the Eastern Hemisphere?
Not yet. To accelerate the development of the global dataset and to provide higher resolution data, 3TIER offers sponsorships on a country-by-country or regional basis. For questions about sponsorship of wind and solar resource maps for specific countries or regions, please call us at 1-206-325-1573 or email us at sponsorships@3tier.com.
How do I use the web tool?
Choose either the Wind or Solar tab.
Enter your location using a variety of methods: latitude and longitude, street address, or zip code.
Navigate using the familiar Google Maps interface by zooming in and out and clicking on the location of interest.
Use "Map" mode to see roads and locations. Use "Satellite" mode to see satellite images. Use "Hybrid" mode to see both. Use "Terrain" mode to see the terrain.
Receive a free, average annual solar irradiance estimate for areas 3TIER provides data.
Why does the solar map disappear?
Within the Western Hemisphere, the FirstLook solar map overlay is disabled at the highest zoom level to make it easier to read the underlying map or satellite image. Solar irradiance estimates are still available as you click on new locations, even at the highest zoom levels, so please continue to look around. For locations outside of the Western Hemisphere, 3TIER is working hard to develop the dataset.
Data File
The FullView Site Analysis report is accompanied by a data file that includes the complete hourly time series of global horizontal, direct and diffuse horizontal irradiance values for the period 1997-2007. 3TIER has added solar zenith and azimuth angles to each hourly value to facilitate further analysis.
Solar Resource Site Analysis
Maps of the area surrounding your site show the average annual solar irradiance for Global Horizontal (GHI), Direct Normal (DNI), and DIF for the area around your site. These maps cover an area 50km by 50km or 31 miles by 31 miles around the site.
Plots of the average monthly solar irradiance for GHI, DNI and DIF values include the standard error for each value.
Plots showing the average diurnal variability for each month of the year are presented for GHI, DNI and DIF.
12x24 tables of irradiance data are color coded to show variations in GHI, DNI and DIF data. These tables are a quick and easy way to assess your solar resource.

What data has been created?
3TIER has created hourly values of GHI, DNI, and Diffuse Horizontal Irradiance over a period of 11 years (1997-2007) that cover the majority of the Western Hemisphere.
How was the data behind your map created?
The dataset is based on 11 years of half-hourly high-resolution (roughly 1 km) visible satellite imagery from GOES satellite data (GOES East and GOES West, using the broad-band visible wavelength channel.) The dataset was collected over eleven years (1997-2007) and has been processed to create 11 years of hourly values of Global Horizontal Irradiance (GHI), Direct Normal Irradiance (DNI) and Diffuse Horizontal Irradiance at a horizontal resolution of roughly 3 kilometers.
3TIER processed these satellite images using algorithms based on the published research of Dr. Richard Perez of SUNY Albany. To develop and validate our model, 3TIER used surface radiation measurements made by the Surface Radiation Network (SURFRAD), Baseline Surface Radiation Network (BSRN), and other regional networks included in National Solar Radiation Database (NSRDB). Snow cover was estimated from the 24km National Snow and Ice Data Center (NSIDC) dataset.
The values of GHI shown on FirstLook represent an average over the time period from 2000 to 2005. FullView Solar Site Analysis reports use data from our full dataset (1997 to 2007). Therefore the value of GHI that a client sees in their FullView assessment may be slightly different from that shown on the FirstLook website.
How do I convert the values to peak sun hours?
There are a number of different units that are frequently used when talking about solar irradiance. PV engineers typically use W/m2 for irradiance. Insolation (now commonly referred to as irradiation) differs from irradiance because of the inclusion of time (e.g. the number of Watts over a square meter for a period of time, typically a day. This gives us the units kWh / m2 / day.) A commonly used term is “peak sun hour” and is defined as the equivalent number of hours per day, with solar irradiance equaling 1,000 W/m2, that gives the same energy received from sunrise to sundown. This term is interchangeable with kWh / m2 /day.
An excellent collection of FAQs about solar energy (and the description above about peak sun hours) can be found at:
http://apps1.eere.energy.gov/solar/cfm/faqs
Why does the data not match my observations?
There are a number of reasons why values measured with ground-based instruments may not match with our estimates.
Unlike many competing products that are available, 3TIER maintains the ability to reprocess the satellite imagery at any point in the western hemisphere. This allows 3TIER to customize and tune our processing algorithms to your solar observational data, nearly eliminating bias, and providing an historical context for your data extending back as far as 11 years. This incorporation of a client’s observed dataset results in superior accuracy and allows our clients to obtain a comprehensive understanding of the resource related risk regarding solar energy development at their project location.
Is 3TIER data more accurate than NREL?
The 3TIER dataset is at higher spatial resolution and uses more satellite images to estimate hourly values of irradiance. This results in a bias that is similar to NREL dataset, but with a Root Mean Squared Error (RMSE) that is appreciably smaller. The smaller RMSE implies that our dataset is more useful as a time series of values. In other words, our estimates of irradiance more closely track the observed values than the NREL estimates on an hour-by-hour basis.
Sponsorships
As part of its REmapping the WorldSM initiative, 3TIER will map the entire world according to the release schedule indicated on the clickable world map. To accelerate the development of the global dataset and to provide higher resolution data, 3TIER offers sponsorships on a country-by-country basis.
