400 W Wind Turbine & 360 W Photovoltaic panels at James M. Hill High School in Miramichi

jmh-2This system is found on the roof of a local high school. It consists of two solar panels that are 1.2 × 1.2 m (4 × 4′), 180 W each from Shell Oil; one 400 W AIRX LAND wind turbine with a diameter of 116.8 cm (46″). The wind turbine can produce 38 kWh/month at a constant speed of 5.4 m/s (12 mph). It can reach a maximum of 49.2 m/s (110 mph), then shuts off.

Both are connected to two VR 12 V Solar Batteries and an inverter inside a classroom with a wall demonstrating all the connections, and also monitors the energy input/output. There is also a camera setup with live feed on a screen in the classroom. Several classroom plug sockets are powered by this system, which have been tested with various appliances by students. A weather station is also partnered with this system.

The owner finds that the solar panels work better than the wind turbine. Sun is more constant, and the wind is very gusty therefore not able to spin propeller properly. He also finds wind turbines are noisy and causes a lot of vibrations.

This set up is a prototype for school curriculum, 5 other schools now have a similar systems modelled after this one.
