Kits and Components
We now have the electronics for the solar tracker#4 available as either a kit or as an assembled board. Because of request for the electronics from many different countries, including developing countries, we have decided to make the kits and assembled boards avaialble on a "$-Donation" basis.
Our cost to make a kit, including the circuit board etching is about $5 CND. An assembled board cost us about $15 CND (including labour) and we also have to pay shipping cost from Canada. We are therefore suggesting a "Donation" of $15 CND for a kit and $30 CND for an assembled board. Of course you can choose to pay more than the suggested price to help offset the cost for non-profit and developing countries.
If you are from a developing country or a non-profit organization we will be more than glad to provide the kits or assembled boards at little or no cost. Please send a request by email to publisher(at)greenwatts(dot)info (replace at=@ and dot=.)
To make a purchase simply click the "DONATE" button below. Please specify if you want the kit or pre assembled board and how many of each. Also include your shipping address and any other details including contact information. A detailed description of the kits and assembled boards is below.
KIT DESCRIPTION: includes all the components and materials required to build a sensor and circuit for single axis tracking (dual axis tracking requires two kits). The circuit can drive up to a 1amp DC motor or can be used to switch a relay. All parts are new.
The kit includes the following components:
- Etched pre-drilled PCB board
- electronic components
- LEDs
- instruction sheet
PRE-ASSEMBLED DESCRIPTION: includes a pre-assembled PCB with labled battery and motor leads and and connected sensor array. Installation and setup instruction sheet. Simply hook up the motor and battery leads, place the sensor unit on the axis of rotation and adjust the sensitivity.
