Canuckle #2

This is our second solar tracker design the Canuckle #2. There is a video of the drive unit on YouTube HERE and a video of a complete tracker HERE. The Canuckle #2 Solar Tracker is made from ABS plastic, recycled printer parts and a few nuts and bolts. We have used 1.5" and 2" standard ABS pipe and fittings for the frame.

The base of the frame can be made to suit any mounting point. For seasonal elevation angle adjustments simply make a 90deg joint using a elbow or t-fitting and secure it by drilling holes at the required angles and securing it with a screw. The top portion of the frame can be made to any size to fit the PV panel, reflector or mirror . Simply cut lengths of pipe to suit whatever you are mounting. The drive unit is built using ABS flat stock which can be purchased or made from ABS pipe.

This tracker uses our new sensor design called the Sun Switch. The Sun Switch uses the photo-voltaic properties of green LEDs to provide light sensing input to TTL logic control on a motor driver chip. See the Sun Switch section for plans on how to build the Sun Switch sensor. If you have any questions please email me publisher@greenwatts.info
