Oahu Solar Measurement Grid (1-Year Archive): 1-Second Solar Irradiance; Oahu, Hawaii (Data)

Published by National Renewable Energy Laboratory | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-12-18T17:36:16Z
Seventeen measurement stations in the south western region of the island of Oahu collected data at 1-second intervals over the course of a year. The sensors are located in a 1-kilometer grid and the information then can be used to predict what PV outputs might be at 1-second intervals for medium-sized and large PV systems. This DOE-funded study by NREL supports the Hawaii Clean Energy Initiative (HCEI), a multifaceted program to substantially increase the use of renewable energy in Hawaii.
