PVGIS.COM vs PVWatts (NREL): Which is the Best Solar Calculator?
When evaluating the production and profitability of a solar installation, two platforms stand out: PVGIS.COM and PVWatts (NREL).
PVGIS.COM is a scientific and independent platform covering the entire world, offering unmatched precision thanks to its advanced satellite databases and high-level financial analysis.
PVWatts, developed by the National Renewable Energy Laboratory (NREL) in the United States, is primarily designed for the North American market and provides a simplified estimation.
Which solution should you choose for a reliable, optimized, and globally usable solar simulation? Let’s compare them in detail.
- PVGIS: Global Coverage, Available in 80+ Languages
- PVGIS.COM is the only solar simulator that offers a complete and detailed analysis for ALL regions worldwide
It is available in 80+ languages, allowing international users to easily access simulations in their native language.
- PVWatts, on the other hand, is mainly designed for the United States and covers only a limited part of the globe. Its use outside the North American territory is more approximate, with less precise results.
With PVGIS.COM, any installer, investor, or individual, wherever they are, can obtain a reliable and detailed estimate of their photovoltaic installation.
