About Kronwatt
Kronwatt makes calculations for energy advice. The aim is simple: figures that hold up and that anyone can follow.
Energy advice needs figures you can follow
Energy advice often rests on spreadsheets only their author can follow. The same measure on the same house can get different figures, without anyone seeing why.
For the homeowner, electricity is hard to see too. The bill does not show when in the day the house uses electricity, or what it costs at that moment. Kronwatt wants to show that, and explain every figure in plain words.

We say what the tool does not do
We say clearly what Kronwatt cannot do, on the same page as what it can.

We start simple
The answer comes first, in plain words. The details are one click away for anyone who wants them.
