Mark Hindelang has installed an urban aquaponics farm in his townhouse in Bangkok, and wanted to demonstrate he can also run it off-grid.
We installed a 2.2 kWp solar PV system and a 200 W Airbreeze windturbine on his roof to power the pumps that run the aquaponics system.
12 SolarWorld modules of 185 Wp were used, to be installed on a tiled roof.
The control board being assembled on-site. Morningstar TriStar charge controller, SunTechnics inverter, breakers and connectors.
Working on the steep roof was tricky and safety harnesses were essential.
The roof-axis was oriented North-South and it was decided to mount half the modules on the East-facing roof-slope and the other half on the West-facing roof-slope to allow for a balanced charging of the batteries throughout the day.
The small windturbine was installed on the highest point of the roof on a pole fixed to the facade.
The battery bank.
and the final control panel, mounted on the wall.
