UK 13 Amp Plug and Mains Extension Cable Safety Issues

Introduction

The initial purpose of this post is to raise awareness of a UK 13 Amp Mains Extension Cable Safety Issue. I came across it by chance when I landed on the PlugSafe site. I’ve taken the liberty of reproducing their information below and enhancing their picture. Full credit to PlugSafe for making us all aware.

As a consequence of a comment on the initial post I have also included an issue with the safety of 13 Amp Mains Plugs too.

Solar Panel Orientation In The Northern Hemisphere

Introduction

In the northern hemisphere solar panel orientation is seen by some as unsuitable because they mainly lie on a north-south axis. This enables them to generate the most electricity when the sun is at its zenith (highest in the sky) and is shining straight down (or as near to perpendicular as possible) on the surface of tilted panels.

This orientation allows panels to generate the greatest possible amount of electricity during the middle of the day. However this is not the best time of day to generate. This is because there are problems connecting intermittent sources of electricity, such as solar panels, to the grid.

Apparently, midday electricity isn’t required so much as afternoon electricity. (I’m not sure what is required in the morning.)
