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 does allow the panels to generate the greatest possible amount of electricity for a period in 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.

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 stop dirt harming 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 and the people in it.
