How to Build a Parabolic Solar Cooker

SolReka Parabolic Solar Oven

Building a parabolic solar oven really isn’t as difficult as it may seem, once the basics are first understood.

There are many popular solar cookers in use today, including the Sun Oven, Sports Solar Oven, and the Cookit, to name but a few. However they all adopt either the solar box or solar trough design. Very few designs are actually parabolic, those that are, are generally quite expensive like the SK-14, compared to the more popular designs. The box solar cooker for example, is simply a cardboard box with reflective panels and a pane of glass which traps hot air in a box.

So what is a parabolic solar oven?

The sun’s rays are collected using a reflective surface like a parabola or curved surface. The main difference between a parabolic solar oven and other solar cooker designs is that the parabolic shape focusses the sun’s rays into one point; called the focal point. A small focal point means a greater concentration of solar energy. With a parabolic solar oven, it is possible to cook food at the same rate that food is cooked in a conventional oven.

Parabolic solar cookers are considered to be a better alternative for outdoor cooking and camping as they require no firewood or the need for gas stoves and they offer fast cooking times.

Why build a parabolic solar oven?

Building a parabolic solar oven will result in a higher power output than other solar cooker design. Remember, the smaller the focal point, the higher the cooking temperature. Water can be boiled in seconds using a sufficient sized parabolic cooker. However, due to the high level of accuracy required in the manufacture of parabolic cookers, a minimal focal point is very difficult to obtain.

Very high cooking temperatures can be obtained with a parabolic solar cooker, thus drastically reducing the time taken to cook food and to boil water. The box design solar cookers generally take several hours to cook food.

To summarise, building a parabolic solar cooker offers faster cooking times than other more conventional solar cooker designs. However, bear in mind that parabolas need more frequent adjusting, pointing to the sun.

How do I build a parabolic solar oven?…

Several methods are available, one easy and ready-made solution is to use a satellite dish. Then line the inside of the dish with a reflective material such as aluminium foil, or better still Mylar. Anodized aluminium could be used, even small segments of mirror. However, the focal point would become ‘scattered’ as the mirror and anodized ally would not give a true parabolic shape.

After researching and testing countless parabolic and general solar cooking designs, the following conclusions have been made: -

  • First of all, work out what size parabola you want to build. As a rule of thumb, every one square metre of reflective surface equates to 1kw of solar energy. This isn’t quite the case for a paraboloid due to its shape, but the rule will suffice. A one metre diameter parabolic which has been engineered to a high spec will pump out more than enough heat to boil water in a few minutes.
  • 800Watts or more of solar energy is sufficient for cooking your solar food.
  • Establish a focal point. Let’s assume you Solar parabolic cooker how to build correctlyare building a one metre dish. A suitable focal point would be approximately 20cm as in Figure 1.

Figure 2 shows a focal point of 25cm which wouldn’t produce the same results as the focal point of 20cm. Solar parabolic cooker build incorrectThis is due to factors such as wind, stand design, and cooling effects. With the cooking vessel situated at a focal point of approximately a third of the way down from the top of parabola, this will ensure sufficient wind protection, as well as an area where the heat is ‘captured’ and retained.

The picture at the top of this post shows one of my earlier parabolic solar cooker designs. Note the depth of the cooking pot, in relation to the actual dish. This oven reached temperatures in excess of 300F (80cm diameter). My current design is lighter (easy to carry in any backpack), sturdier and more powerful.

It is also important to choose the right cooking pot for the cooker. It has to be dark in colour and placed in the correct position, namely in the middle of the focal point. It also needs to be oriented to the sun and placed on a small stand that sits at the point of focus for the oven.

Parabolic solar cookers can work for 60 to 90 minutes unattended. If you find that the food is not cooked or that another pot has to be heated, then simply adjust the dish to point to the sun every 15-20 minutes or so.

One final note, if the focal point is too low or too shallow, i.e. a very deep parabola as in Solar parabolic cooker build deep dishFigure 3, then the sun rays will ‘bounce’ on the top and sides of the cooking vessel, and not from underneath as they should do. It is also very difficult to manufacture – ref incorporating stand with a deep shaped dish. There is also a smaller surface area, in that the sun’s rays only penetrate whatever diameter the dish is set to, irrespective of depth.

Figure 4 shows the opposite of a deep parabolaSolar parabolic cooker build shallow dish. This design is workable, providing a relatively large diameter dish is used. Factors such as the wind and insulation of cooking vessel must be taken into account for this audacious design. Many satellite dishes have a focal point just outside the depth of the dish. This is due to ease of manufacture and optimal threshold for capturing frequency bands.

Suitable materials for building a parabolic solar cooker.

- Reflective chrome vinyl, highly reflective material which also comes with an adhesive backing. For more details visit solar cookers reflective vinyl section.

- Finished anodised aluminium or mirrors (expensive).

- Mylar – used in hydroponic set ups.

- Aluminium foil – cheap and cheerful, however creases and tares can play a large part in the build. Foil is a great starting point as it’s cheap and readily available.

So now you have a good understanding of what a parabolic cooker is and the main concepts needed to start building your very own parabolic solar cooker. So, what are you waiting for… :-) Happy building.

    I really enjoyed your article Rob. I look forward to its release. If I remember correctly I believe you estimated the temperature at the focal point of the 80mm to be slightly more than 300 degrees Fahrenheit? i may have gotten that wrong….Vern

  2. SolRekaNo Gravatar Says:


    Many thanks for those kind words.

    You are correct, temperatures in excess of 300F have been obtained with the 80cm diameter dish. Please note that the results were recorded in England (weather – occasional cloud cover, temp average 22C)

    I can only dream of seeing higher temps in other, warmer climates.

    I look forward to receiving reports from SolReka users from from off lands where temps typically reach the high 20′s, low 30′s.

    Larger dishes will become available, and customers will have the chance to order bespoke (any-size) parabolic dishes. However, I must currently focus my efforts on bringing the 80cm to market, subsequent parabolas will follow soon afterwards.

    Super article Rob. Parabolic cookers definitely qualify as dorkage. I’m gonna see about building something like this. I built an “oven” when I was in Costa Rica, consisting of reflective panels which I set up around my hotplate, then my only cooking implement. I set up a rack over the hot plate and put the scones on it. It worked pretty well all things considered.

    I have seen your interesting note on solar oven;it must be very efficient;but how much does it cost?; there are a number of interesting models like yours;their main disadvantage for use by the poor in countries like India and Africa is their cost; I designed a solar cooker with a semi- paraboloid shaped bamboo basket[available locally in most Indian rural and forest villages] for Rs.40[80 cents]; for the reflecting surface I used locally available ‘eating plates’-these are paper plates of 15′ diameter coated with a thin foil of Aluminum or a silver colored polythene film-;each cost Rs.1.25[2 cents!] ;five or six of them will be adequate;in all the cost does not exceed one dollar;it cooked rice in two hours;the cooking time can be brought down by fine tuning;the rice was put in a Aluminum vessel enclosed in a black polythene bag or in a glass vessel;the glass vessel was quicker in cooking. i wil send some photos by next post.

    what sort of turbine system would you recommend for a large parabolic dish say i.5metre diameter? how much electricity could be produced?

  22. SolRekaNo Gravatar Says:

    Hi gabe
    I’m afraid I cannot answer that question for you. Suffice to say a 5m parabolic is massive in both size and power output.

    For every 1 square metre of sunlight you can expect to produce approximately 1kW of energy. So a minimum of 5kW cou ld be anticipated for a 5m dish.

    Perhaps a Stirling engine array would be a more suitable application for such a dish.

    I hope this has helped somewhat.

  32. SolReka | Parabolic Solar CookersNo Gravatar Says:

    Sure thing Xellos

    Regarding attaching the vinyl to a suitable backing material. For the version 5 build solar cooker I used PVC sheeting as the backing material.

    However, if you look closely at the picture, you can see that the shape isn’t reinforced due to the ‘flimsy’ nature of PVC. (difficult to see in picture)

    I then moved onto 1.5mm HIPS and plastic sheeting for the backing material, as a result the parabolic cooker now produces much better results. Easily reaches temps over 150C.

    Please let me know if I can be of any further assistance.

  47. SolRekaNo Gravatar Says:

    Cooking pots is an interesting subject. It depends on which design of solar cooker you use. For a box type cooker, a good insulating cooking pot is essential. One that retains the heat such as an iron pot.
    Conversely, for parabolic cookers, due to the intense heat produced, any cooking vessel will suffice. Just make sure you don’t use something which spontaneously combusts when placed in the focal point.

  49. SolRekaNo Gravatar Says:

    Is it a box or parabolic cooker you are building? Simply placing a cookie on a plate might not be enough. May need to thermally insulate plate, or use a high convection plate which will easily radiate heat and in turn cook your cookie. All the best with your endeavour.

    What are the drawbacks to Mylar aka why is it third on the list? Will emergency blankets work (cheaper and decent size) or doesn’t it have to be the hydroponic kind (similar in cost to chrome vinyl)?

  64. SolRekaNo Gravatar Says:

    Hi ChibiHoshi

    Mylar is great for solar cooking, so is kitchen (aluminium) foil, chrome vinyl, cds, basically anything which reflects the sun will work fine. The higher the reflectivity the better the performance of your solar cooker. Mylar and chrome vinyl have a reflectivity of approx ~ 98%, so these are the preferred materials to use as they are the most cost effective.

    Emergency blankets and food wrapping foil would work fine. Perhaps best used on box type cookers as you can stretch these materials out and get rid of any creases/folds.

    From all the various methods and materials I have tried when building solar cookers, I have to say that the parabolic design with chrome vinyl is the most cost effective method which produces the best results.

    Let me know if I can be of any more help. Happy solar cooking.

  66. SolRekaNo Gravatar Says:

    Hi Johny

    The videos are too complex in my opinion. Over-engineering of a simple problem. Parabolic shapes need to be highly accurate in order to make them efficient to use. Hand drawing parabolas will create more of a bowl shape than a parabola.

    The best way to create a parabola is to use a simple piece of CAD software and to have a good understanding of how parabolas work ref parabolic equation.

    Hope this helps.

The town’s people was very thankful about this since they can already watch television after a days work in the farm or they have lamps on little store where they used together around after dinner. This is very helpful since electric bills are goingup every year. This is a big help for end consumers.

As time passes, I have come to understand that the particular symptoms of mesothelioma cancer are caused by the build up of fluid regarding the lining on the lung and the breasts cavity. The infection may start in the chest vicinity and multiply to other body parts. Other symptoms of pleural mesothelioma cancer include weight-loss, severe inhaling trouble, vomiting, difficulty eating, and puffiness of the face and neck areas. It ought to be noted that some people living with the disease do not experience just about any serious signs at all.
