The solution is build up with two components: a Data logger service and a web application to visualize the data. The whole application is running on a single fanless Alix.1C board. The Alix.1C is not available anymore but the successor Alix.1D is similar. You can get it for instance from NRG - Systems or as a complete bundle at The board consumes only 4-5 Watt ~ 10 Euro per year. Windows XP Professional is installed on a 4GB Sandisk Extreme III CF card. Total hardware costs is about 152 Euros, XP Pro can be bought for about 30-40 Euros already.
Alternativly it is of course possible to use an (old) existing Notebook or an home server. Some users are already doing it.

A sophisticated description in French about SolarView on an Alix PC can be found here: The owner of this page provides as well a full translation of SolarView@Windows into French language.


Data logger software
