Solar Panel Orientation In The Northern Hemisphere

Introduction

In the northern hemisphere solar panel orientation is unsuitable because they mainly point south. This enables them to generate the most electricity when the sun is highest in the sky and is shining straight down (or as near to that as possible) on the surface of tilted panels. This approach does allow the panels to generate the greatest possible amount of electricity, but not at the best time of day. This is because there are problems connecting intermittent sources of electricity to the grid. It seems midday electricity isn’t required so much as afternoon electricity. (I’m not sure what is required in the morning.)

Dyson Slim DC18 Filter Cleaning

Introduction

This article describes the Dyson Slim DC18 Filter Cleaning process for the Pre-filter and the HEPA (Highly Efficient Particle Arrester) Post-filter.

Many devices in this world which pump air have air filters. They’re installed to prevent dirt getting into mechanisms, bearings, etc.. Without filters that dirt would ultimately make them perform badly or fail.  The air filters clog up instead and have to be replaced or cleaned at regular intervals. The Dyson Slim DC18 is no different. It has two air filters, one to protect the motor and the other (the HEPA filter) to protect the local environment.
