    Your All-Season Solar Cooker: How to Cook During The Winter

    November 21, 2016 2 min read 14 Comments

    Which types of solar cookers are all-season solar cookers? As the weather dips in the fall, we’re often asked how exactly these stoves can cook so effectively even in the cold. To answer this and other questions, we’ve created a handy FAQ.
      

    All-season solar cooker: How do solar vacuum tubes work? 

    Air is pulled out of a double-layered borosilicate glass tube and permanently sealed, forming a vacuum. This highly specialized process results in some unique properties, the most important being thermal insulation. Light can be absorbed by the internal layer of the tube and stored as heat. Without air to transfer heat from the inside of the tube to the outside, the vacuum provides near perfect insulation from the cold. 
     

    Is it really an all-season solar cooker? Can they cook during the winter? 

    Yes, very well in fact! The GoSun Sport has been shown to cook hot meals at temperatures below 10°F (-12°C) with no problem aside from the time required to preheat.
     

    How much longer does the GoSun cooking technology take to cook during the winter? 

    Cook times during the winter may increase your cooking time by as much as 15 minutes, while the tray and tube come to temperature. The GoSun truly is an all-season solar cooker, but cook times are definitely affected by weather and sun conditions. Once this point is reached the stove cooks as quickly as a warm summer day.

    Why does the GoSun cook faster on some winter days than a summer day?  

    There are two main reasons solar cooking during the winter can lead to faster cook times: air quality and reflection.
     
    Air Quality: As any winter sportsman can attest to, sunburn is not exclusive to warm weather. In fact, cold mountain air holding little moisture to diffuse the light, makes for direct and intense sunlight. Put simply, the thinner the air, the stronger the power of the sunlight.
     
    Reflection: When cooking on a snow covered slope, particularly with the low angle light of dawn and dusk, the snow often acts as a reflector, multiplying the total amount of light entering the stove. More light means faster meals. 
     

    How can I better utilize my all-season solar cooker in the winter?

    Open Sparingly: Opening the stove becomes more costly as the environment becomes colder. Just set a timer and check when the recipe should be approaching completion.
     
    Use Steam As An Indicator: To check the status of your food without opening, watch for steam. Steam rendering from the GoSun Sport typical indicates food is near completion. This is especially the case for vegetables and bread.
     
    Store Your Stove Indoors: Skip an extended preheating cycle by simply keeping you stove inside rather than in the garage.
      
    Stay Inside: Have a sunny window? You’re in luck! Just place your stove facing outward. It may take longer due to some window’s UV coatings… but then again you’re inside.
    With GoSun, you can start cooking with the Sun year round, anywhere the Sun shines, regardless of the cold!

    My favorite place to use my sport is the parking lot of my local ski resort Monarch Mountain, pop some grub in the tube, take a few runs, ski by the car for a hot lunch, wash it down with a cold beer. Best ski bum cooker out there, no need to worry about open flame. The support rails close right in my ski rack. Roof top cooking!

    Once you start to use a GoSun it almost becomes addictive. It’s like the body can’t do without the food prepared from the GoSun, particularly vegetables. We use ours nearly everyday…

    If you guys made a gosun grill that could also use electricity to heat up food when there is no sun, then I would be a customer so fast. I live in Seattle where you don’t get as much sun, in the winter the days are much shorter. The versatility of a combined electric and solar cooker would be awesome. Either built in or through accessory of some kind.

    I can’t wait to try this out. Let’s hope for a lot of snow here in the Rockies. We are at over 5000 feet and should be able to take advantage of the powerful sun.
