The E-Si Team make a trip over to Sark to install 8.5kW of Solar Photovoltaics.


The team on the way to Sark to install 8.5kW of Solar Photovoltaic.
It was a 5.45am start, so the boat allowed for some much needed catch up on some kip!

Bus then bicycles was our mode of transport in Sark.

Testing the batteries for creating second island grid at Clos Bourel. 48V config to Trace 4.5kW inverter which grid connect and export to our grid. In this case we are the Grid Managers!

PV Runners all up by the 2.5Kw team. Panels on next.

PV install is Go. This is Sam Trainee REE battening out for the 1.2kW array.

3.8kW solar pic, looking good. We had a shortening window and by that time needed to be off site on boat by 6pm, so it left us an 1hr 45mns to complete.

The team had 3/4hr left before departure and 1 hour before the 2.8kW system goes live. Time was of the essence!

Heat Pumps, PV's and HeatKubes!



We are having our busiest August ever, with two 8.5kW solar photovoltaic installs going on at same time (17kW Total)(that used to be 1kW a year!). 

 We are building 2 x HeatKubes in our workshop for immediate install, we have a further 12 more HeatKubes to build and install next few months.




We have almost completed our first Loxone home automation system, controlling a bespoke design of dehum and pool heating in Fort George. This latter install is unique in the world, being the most efficient way of heating and controlling moisture ever.

Its not been easy, on all fronts we have been innovating hard with steep learning curves. Just sourcing the right kind of sensors has been fun, pulling in from the US and France as few UK distributors have the right products. 

In the photos below you can see a massive 2 x 14kW of Mitsubishi Air Source Heat Pumps connecting in through our bespoke design buffer system allowing the legacy radiator system to not interfere with the modern electronic heat pump controls. In Total we have a high performance 28kW of heat pumps to heat hot water, radiators and a small UFH circuit. 




The photos of the roof below show the stainless steel slate hooks with 'Hall Clip' solar flashing to which overall across two roofs, 8.8kW of a new type of modulating solar PV will be installed. This comes with default internet connection so power output can be viewed from anywhere in the world.
