solar oven trackers
tracstar makes two solar oven trackers. the smaller version of the self-powered tracker described elsewhere can be used for solar ovens advantageously.
since that tracker is somewhat expensive and over designed for most solar oven users including hopeful deployment of solar ovens in the third world, tracstar has designed an even simpler version. with this system the solar oven sits on a lazy susan turntable and a motor with a wheel turns the oven and turntable. a small solar panel powers the motor. the oven must be placed on a flat smooth surface large enough that the wheel can walk around an arc with the solar oven in the center. trackstar will build these units for $45 currently. if we get enough demand we will try to get the price down from there.
the use of trackers for solar ovens permits unattended operation. this permits the oven to be left "on" so that energy can be stored for later use, for prolonged cooking as for some dishes and canning, or even arranged for the cooker to start cooking at a later time. a tracker also allows the use of a thermostat so the oven can be kept at a constant temperature.
solar oven tracker update
currently the above is all that is available, however, there has been an increase in interest in these trackers lately and we are getting low on the parts we use to make them. consequently we are thinking ahead. for the next version we will probably make a small stand and include the platform for the stove which currently the purchaser must supply. this way the tracker can be used on any surface and will be a little easier to use not being flat on the ground. we will also probably purchase a better gear motor. this will add some to the cost but greatly improve the product and be usable "out of the box."
many people have purchased other controllers than the simplist so here is a complete description of the self-powered controllers we make. each controller uses a small panel that is made up of 3 or 4 solar cells to produce a nominal 1.5 volts.
these are made by hand in limited quantity using the best quality cells.
