One of first steps in the development of solar energy projects is a pre-feasibility study. A key requirement is to make decisions on basis of reliable data, with limited time and resources.

Bad data in equals bad data out. This well-known phrase is very relevant in a context of technical design and energy simulation of photovoltaic (PV) power plants. Most solar companies understand this and are carefully evaluating uncertainty of solar resource data used for feasibility purposes ...

To assess the solar resource or energy yield potential of a site, we model the solar resource/energy yield using best available information and methods. The resulting estimate is the P50 estimate, or in other words, the “best estimate”. P50 is essentially a statistical level of confidence suggesting that we expect to exceed the predicted solar resource/energy yield 50% of the time. However, ...

We’ve released a new tool that will allow Solargis users to request time series data for PV systems with trackers. You can choose from 4 types of tracker options: 1-axis horizontal, 1-axis inclined, 1-axis vertical, and 2-axis tracking. It is also possible to specify tracker rotation limits and enable/disable backtracking.

The old GOES-East satellite, also known as GOES-13, was launched to orbit in 2006. The data coverage is North and South Americas.

The process of estimating solar radiation data uncertainty can be sometimes unclear. We've tried to summarise in 4 simple steps.

Just as there are horses for courses, different forecasting techniques are more suitable depending on the intended forecast lead time.

In collaboration with the World Bank Group, today we are releasing new mid-sized maps of 145 countries on Global Solar Atlas.

The meteorological satellite Meteosat-7, which had been providing satellite imagery for the Indian Ocean region has now been decommissioned.

Solargis releases GHI, DNI and PVOUT maps for Google Earth in kmz format.

Precipitable water or ‘PWAT’ in short, is the depth of water in a column of the atmosphere if all the water in that column were precipitated as rain.

We have developed new functionalities of reports that are available now through our climData.
