Apart from the Lux software to monitor the system I have been using the following to estimate the solar production

Solcast has been very useful. It predicts the amount of solar production your system will generate over the next three days. I am hoping to write a Python script that will make this easier. The data can be used to decide if you can cut down, or need more overnight slots to charge the battery

Actual production for the 8th February. The green line is the solar production

With the free version you can add two roof orientations. As you have seen I have three orientations. I decided to put the eight panels on the front on one roof and the back would be correct

Azimuth Solcast compass guide

When you setup Solcast it will ask for the azimuth of your roof. As a guide mine are:

Back panels: 68

Front Panels: -112

My introduction to computers started at my middle school in 1981 when our maths teacher brought in a ZX80. That led the computer club being founded and using a Research Machine 380Z

My first computer was a 48K ZX Spectrum which I loved to programme. Once I left school I worked as a photocopier engineer, then a fax engineer and finally moving on the Apple computers.

For the next 30 years I worked as a system administrator. I now work in the cyber security industry as a Sophos Professional Services consultant
