FAQ

What makes NASA POWER different from ERA5?

NASA POWER focuses specifically on energy- and agriculture-relevant variables with an easy-to-use API and web interface. ERA5 offers higher resolution (~31km vs 55km) and more atmospheric variables but requires more technical setup to access.

Is NASA POWER suitable for solar energy assessment?

Yes. NASA POWER's all-sky surface solar radiation data is specifically designed for solar energy applications including PV system design, site feasibility studies, and solar resource assessment.
