Whether it’s the waning late summer afternoon sunshine, or the fleeting window of strong sunlight in mid-winter, knowing how to refocus your solar oven is essential knowledge for a solar chef. So, how easy is refocusing? Ha, it’s a piece of cake! Pun intended! To refocus a solar oven, simply watch the shadows around the oven and keep them even on all sides. This keeps it tracking the sun’s path.

The Global Sun Oven has a built in leg which allows for easy sun tracking. It is suggested that a refocus is needed about every 30 minutes for the Sun Oven. This also depends on the time of day, the desired temperature to keep and what type food is being cooked. The Global Sun Oven also has a built in “levelator” feature that keeps pots level in the oven chamber, thus avoiding spills which is a real advantage when refocusing. A different commercially available model, the SOS Sport Solar Oven, is cleverly designed to accommodate two different sun angles; a 30 degree for direct mid-day sun and 60 degree for low angle sun like early morning, late afternoon or winter.

Some solar oven models, such as the Tulsi Electric and SunFocus, have an electric backup feature. The efficient electric heater within those ovens, normally takes over if clouds move in. But, it is also a handy feature in case you forget to refocus, or were late in getting back to your cooking, etc.

So, as you can see, there really isn’t much of a learning curve with refocusing a solar oven. Paying attention to the seasonal changes and the sun’s angle are something that will come with experience as you continue to enjoy sun-cooked/free energy meals.

The newest, and largest, solar electric (hybrid) oven is the SunFocus (TM). Manufactured by SunBD Corp, it has a large cooking chamber; 13.5 x 13.5 x 6.25 inches. Most notable, is its high quality, made in America craftsmanship.

With such a large internal chamber at your disposal, you will find it easily accommodates most casserole dishes, a pizza, whole chicken, or small turkey. By using those, yes..dark-colored thin-walled metal pots, you can prepare several dishes simultaneously with this “big boy” solar electric oven.

The most touted feature of a solar electric oven is its electric backup. Should cloudy skies befall you in the middle of your solar cooking day, just switch the SunFocus to electric mode, the thermostat will keep up the temperature until sunny skies reappear (as they often do), or, until your meal is ready. A solar electric oven is very handy in the portions of our country not so blessed by sunshine, like New York and Pennsylvania. The highly efficient electric element within it operates on just a few pennies (uses 75% less electric than a traditional electric oven). It comes with side reflectors to increase cooking temperatures while using it as a normal solar oven. Temperatures of 400 degrees F are possible without the electric backup.

Like other solar cookers, the SunFocus uses a clever suitcase design with a carrying handle which makes it portable and easy to store. Remember, any solar oven may be a lifesaver during an emergency or catastrophe.
