New Solargis Prospect app: making pre-feasibility easier and more reliable

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.

Solar resource data – time series data vs monthly averages

Solar resource data – time series data vs monthly averages

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 ...

How to calculate P90 (or other Pxx) PV energy yield estimates

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, ...

New 3D tool for configuring and visualising tracker movement

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.
