SolarBI reviews Solcast

In the world of Solar Irradiance there are great services out there producing awesome data for solar projects.

One of my favourites is Solcast, they do a cracking job democratising Solar Data. 

So kudos to its founders Dr.  Nicholas Engerer and James Luffman.

Solcast has two big groups: historical & TMY and live & forecast solar data. You can have static data results or live ones, connected to your systems via a pretty handy API toolkit.In addition to other cool stuff, you can create a data request for historical data very similar to our search engine. I’ve prepared a quick table to what’s on offer, how it compares with ours.

Truth be told, we didn’t pay the $400USD to confirm the speed or compare the data, but we use their estimate delivery time.  Who won? You decide.  We like them, and we hope you do too! I am super impressed with the work that the Solcast team has done. By far the most complete solution out there – it’s intense, detailed, and offer a wide range of products.  Well Done, Well done!!
