E-Si have recently installed the Eddy GT wind turbine at the Vale Castle for this years Vale Earth Fair music festival which is happening this weekend.
The turbine will be up for a few weeks producing electricity which is fed into the grid to offset the music festivals carbon footprint.

|3kw Solyndra Solar PV array which the team installed and wired in 24 mins.|
Solyndra designs and manufactures solar photovoltaic (PV) systems, comprised of panels and mounts, for the commercial rooftop market. Solyndra’s technology is a proven and scalable solar solution that offers strong ROI and economics for the rooftop owner. The company has installed its systems on more than 1000 rooftops in more than 20 countries.
In 2010 Solyndra was named “One of the 50 Most Innovative Companies in the World” by MIT’s Technology Review Magazine. Using innovative cylindrical modules and thin film CIGS technology, Solyndra systems are designed to provide the lowest levelized cost of electricity and the highest kilowatt hour production per rooftop for typical installations. The unique Solyndra form factor is designed specifically for the commercial rooftop, offering the fastest and easiest installation, a non-penetrating mounting system, and superior wind, snow and soiling performance. In addition Solyndra offers energy and conservation advantages when installed in conjunction with a white or “cool” roof.
Founded in 2005, today the company manufactures its products entirely in the United States in a state-of-the-art 300,000 square foot front-end manufacturing factory and a 500,000 square foot back-end facility. The manufacturing facility has helped Solyndra drive costs down dramatically allowing the company to offer highly competitive “all in” installed cost on the rooftop. In 2011 Solyndra will double it’s production capacity, ramping toward 300MW. The company employs approximately 1050 employees around the world and has offices in the United States, Switzerland, Germany, Italy, and France. Revenues were approximately $140 million in 2010.

|They are extremely heavy so had to be lifted off by crane.|
The 1kW UGE ‘Eddy’ turbines have finally arrived from Urban Green Energy! A customer of ours is investing in them and taking the risk, if they work out we will go into partnership and promote them. We are UK agents at present

Paul "in the trenches" studying the new innovative high temperature pipework design by E-Si
We had to strip down the modulating pump as water had through the factory seal into the electronics and it was tripping out the elecs. Dave, tech geek, put it back together after drying it out with a hairdryer and all is now fine.
We discovered the pump has got more brain cells than its installers and more computing power than first man's spaceship on the moon!
|Paul lays his hand on the pipe, which we had waited for weeks - in the end we sent Craig to France to collect it ourselves.|
400 metres of 90mm duct.
The Duct with pipe stuffed in it, snakes under the first greenhouse on its way to the second - the 'solar collection' greenhouse.
It was Jamie's job to connect two lengths (50+10m) here to extend to where the kit sat.
To the ASHP/Solar heating hybrid source.

I did some heat calcs for a new home/extension in Jersey today. The results and solutions will be of interest to many.
The Design Heat Loss @ -1C outside and 21C inside = 12.7kW. Allow for Hot Water at the same time, add 3kW = 15.7kW
Allow for Secondary Hot Water circulation at the same time, add 2kW = 17.7kW. There are several heating alternatives, depending on requirements. 1. Ground Source Heat Pump (GSHP) boreholes. 2. GSHP slinkies. 3. GSHP ground panels. 4. Air Source Heat Pump(s).The IVT GSHP comes with ‘direct electric’ backup built into the machine in case of high loss in cold weather or failure of the heat pump and requirement for extra hot water. The Mitsubishi ASHP are ‘modulating’ as standard, which give flexibility in design and come in 5, 8.5 and 14kW variations. The IVT heat pumps come in outputs 9, 11, 13, 17kW and are ‘on-off’ types, so rely on the direct electric immersion for design flexibility.

Fionn and Connor, 'Renewable Energy Engineers', make final electrical connections having completed the mechanics, showing how important it is to be multi-disciplinary.
Fionn and Connor complete the mechanical installation of the BP Solar grid tie installation in Clos Bourel, Sark. This is a unique install, see next photos and Situation Reports.
The Grid Tie Inverter produced 420W at 5.15pm as last wire was attached, with some shadow from a nearby apple tree. In full sun the output will be around 900 to 1000 watts.
The latest newsletter from Sark Electricity. Very positive, but very interesting the tone that really oil is becoming a big issue. Why does the e in their logo look like ours?!!!
The digital thermostat showing the Air Source Heat Pump heated hot water temperature of 54C.
Air Source Heat Pump 4th May 2011. I remember changing this over in the cold windy winter on my own!!! (Paul Fletcher, author).
Over time the terminal on this battery corroded. Today I repaired it by cutting away the lead around the screw threaded stub and reconnected it.
The battery room of Clos Bourel, 24 x 2V BP Solar battery cells, making 48V DC, feeding a 230V AC output Trace Inverter.
The Trace inverter output from the batteries peaked at 17A under observation. The assistance from the Trace ('grid-tied') SMA Sunny Boy greatly assisted the battery powered inverter under great load, and maintained good stability.

"The neatest Niko lighting control box I've ever seen" says E-Si CEO.
Daniel's magnificent house. A feat of modern, energy efficient, ecological architecture and mechanical and electrical installation. Heating and power went on today, client moves in tomorrow night! Hurrah!!!
Luminaire will be added to the Projects page at e-si.com very soon for more.
I recently visited E-Si's R&D site, the Clos Bourel Energy Project in Sark to help build an alluminium frame for some Solar Photovoltaics. Although it's not out of the norm to find me occasionaly on site, I am mostly always at the E-Si offices, so it was exciting as well as educational and interesting for me to take to the tools and best of all visit a small beautiful island as a bonus!
The jobs in hand for the day were constructing the frame for the Pv's and erect two wind turbines.
