Following recent developments in the pricing of electricity for households with solar panels in the Netherlands, I got interested in the energy balance of our own household. A little over two years ago, we moved into a newly build house that qualifies as a "zero-on-the-meter house". This qualification implies that -- under certain assumptions -- the house has a net energy balance of zero or below zero, i.e....
As part of a larger effort to get a better understanding of our energy consumption and production, I wanted to log the power generated by the photovoltaic installation in our house. We use a Solax system consisting of 8 solar panels, a Solax X1 inverter and the Solax Pocket Wifi 2.0 device. Via this manual I will explain how I got the data extracted. In the rest of...
As part of a larger effort to get a better understanding of our energy consumption and production, I wanted to predict the production of our solar arrays on a day to day basis. This requires information on the Global Horizontal Irradiance, which is calculated in the weather models by the Royal Netherlands Meteorological Institute KNMI. Because the KNMI is a publicly funded organisation and is part of the...
Last year I wrote a blog post on the twisted treat that my family makes every years for new years eve: Nonnevotten. I tried to standardize the recipe to measures of weight instead of volume and to standardize the process of making them to get more reliable results. If I want to improve on the recipe, I need to experiment a bit with the recipe to see if...
You probably got here after clicking on 'Blog' in the top menu. Unfortunately, there is not much to see here at the moment. I am currently working on rebuilding this site and writing new content. In the future you can expect blog posts on a broad range of topics. As this is my personal website, there will be no specific theme and the only common denominator will be me....
