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 beautiful and awe inspiring walk from the top of Sark down the hill to the Harbour.
