The environment is potentially a huge subject. 

Conceptually it can be a terrarium or even smaller, up to the whole world.

There are other Solar power diverters, but I went for the myenergi eddi, so this is about that one only.

According to the myenergi eddi website.

Save money and energy with British made power diverter
Use your excess energy and save
Bring an eddi into your home and you can make the most of the 100% green energy generated from your solar PV or wind generation system.

Rather than exporting excess generation back to the grid as per a standard PV system, with our intelligent eddi power diverter, that extra power generation is instead diverted back to your heating systems, thus heating water on 100% self generated green energy.

It is a simple concept, but a wiz bit of Tech.

How does an energy diverter work?

It monitors the Grid connection and as soon as you start generating more electricity than you are using, as soon as you start exporting, it turns on the immersion heater in your hot water cylinder, creating an additional load, and stopping the export. If you turn something else on it the house, it reduces the power going to the immersion heater by that amount. It only uses self generated electricity that would otherwise go as export to the grid.

It stores the surplus electrical energy produced in the form of hot water.

To maximise the storage capacity, you would have cold water to start with and a very large cylinder or Thermal Store. However, there are some impracticalities with that, including the potential of cold water to wash with in the morning before any diversion had commenced.

Of course such diversion into hot water can not continue indefinitely. A home with super heated steam in a cylinder is not a safe option. The thermostat attached to the immersion heater would close the circuit. For the avoidance of doubt, not the one for the cylinder, which controls the Domestic Hot Water side of the Central Heating. At that point, with self use of electricity being less than the PV panels are generating at that moment in time, and nowhere for the power diverter to divert to, export of electricity would commence.

Solar PV and Battery Impact

 

Solar PV and Battery Impact

 

I have been watching the development of Solar photovoltaics (PV) for many years.

Initially as part of a design project for a all terrain expedition vehicle / motorhome. A roof predominantly covered with PV panels and a bank of 10 deep cycle batteries. I also went to a Caravan and Motorhome show and saw a PV panel mounted on a devise that looked like a satellite dish support, but instead of having a dish, it had a PV panel. It tracked the sun, to maximise power generation.

The Oyster SunMover System is an intelligent GPS controlled solar tracking system. It can automatically track the suns path throughout the day and adjust as necessary to maximise solar energy capture making it more efficient than standard fixed solar panels.

The system itself consists of a 75W solar panel attached to a specially designed electronic mechanism which is controlled internally via its own control system in the roof unit making installation simpler. On average the system is capable of harvesting approximately three times the power of a 75W fixed solar panel on its own. This is even more important in the winter months where the angle of insolation (the angle of the suns rays on the earth) is much greater i.e. the sun is effectively lower in the sky. The Oyster SunMover can adjust the elevation (the angle of the solar panel) to maximise energy harvest throughout the year.

This was a long time ago, and I can't remember if the make was Oyster or the price. However, at over £2000 before being discontinued, for just one panel, it was not directly pursued.

Environment at home

 

It is important how we use the environment around us. In the past it has sometimes been more about abuse that use. We are now more aware of the environment around us, in several different ways. 

  • the surroundings or conditions in which a person, animal, or plant lives or operates
  • the natural world, as a whole or in a particular geographical area, especially as affected by human activity.

In this section, I look at not the wider environment around us nor climate change, but our home. Of course the wider environment impacts the local environment of our home, and the things we do within it, hopefully in an Environmentally Conscious manner. In and eco friendly and sustainable way.

 

The Wider Environment

 

In the Wider Environment section I look outside of by home and discuss a bigger area of concern, weather that is the town, the country, or the continent in which I live. Or indeed the World.
