The importance of quality solar data ground measurements in tropical climates

New analysis by Solargis reveals that the variance between modeled solar irradiance and actual measurements is more pronounced in tropical regions than in temperate and subtropical zones. Read article

Lowest expected operating temperature (TLEO) & Solargis approach

Extreme cold conditions can lead to increased voltages in photovoltaic (PV) modules, potentially causing system overload. Learn about the critical importance of understanding the lowest expected operating temperature parameter (or TLEO in Solargis language) for optimal PV array sizing. Read article

The pros and cons of 1-minute, 15-minute, and 60-minute solar data

Depending on the source and desired application, solar data can have distinctive temporal resolutions, such as sub-hourly (1-, 2-, 5-, 10-, 15-, 30-minute) or hourly intervals. But how are you supposed to know the difference, and why should you care? Read article

Why is 1-min data essential for solar project financiers?

One of the key challenges for solar project financiers is to assess the expected energy production and revenue of a project over its lifetime, considering the uncertainties and fluctuations of the solar resource. Read article

4 reasons why PV project designers need 1-minute data

To design optimal PV projects, designers must consult 1-minute data which paint the most accurate picture of a plants’ PV power potential and output, while providing increased financial certainty to solar investors. Read article

IEA’s Worldwide Benchmark new study shows the highest overall GHI and DNI accuracy for Solargis model
