Solar panel performance declines over the years. I thought it might be interesting to see how mine compares. Of course weather comes into it, but hopefully this will be a useful guide.

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
