In our previous post, we have discussed the concept behind making a solar oven for light duty at home; today we will see how to make one solar oven for heavy duty at home. We will discuss here about each spare or component which will be used here, we will also discuss the design and manufacturing process of homemade solar oven for heavy duty services. Finally we will see here the life cycle analysis.

As we know that nonrenewable energy sources are limited and we need to save these sources by using other sources of energy such as solar energy. We can be securing a solar oven of heavy duty and powerful energy of sun will be utilized in our daily need and we can save fossil fuel and also reduce our price against electricity and gas bill.

Material selection

Material selection for any product is very critical step as overall performance of that product depends on raw material used.
We will consider here material for manufacturing solar oven for heavy duty & following materials are required for manufacturing a solar oven of high duty.
  1. Drum of metal such as drum of oil
  2. Jigsaw along with blade for metal cutting
  3. Sheet metal such as metal which is used in pressure cooker
  4. String
  5. Measuring tape
  6. Marker
  7. Sheet metal shear
  8. Metal splashing
  9. Reflective paint such as Barbecue-rated
  10. Drill m/c & de greasing shop

Design and manufacturing Process

Before going to design phase, designers observe following terms in order to provide the best design for solar oven
  1. Availability & Costing of materials
  2. Site of heavy intensity of sun light
  3. Capacity required as per customer need
There are following simple steps that should be followed during manufacturing of solar oven


Shear or cut the drum of metal with the help of jigsaw in vertical direction and only half portion of this sheared drum will be utilized for this purpose


Cleaning inner surface of drum of metal with the help of de-greasing soap


In this step we have to cut one rectangle and two semi circle shape of sheet metal for Contouring inside of half portion of metal drum.


In this step we have to fix sheet metal inside of drum. To complete this task we have to make holes by drill m/c in drum & sheet metal surface at same distance and then we have to fix sheet metal with the help of rivets.


In order to maximize the amount of heat, we provide a layer of reflective paint inside the drum.


In this step we have to produce a continuous lip of metal across 3 out of the 4 top edges of the solar oven.


In this step we have to provide a very thin layer of insulation over the outer surface of oven and it might be done with the help of spraying across outer surface of oven


In this step we provide a base for our solar oven. Wood will be the best to serve as base for oven. We also drill holes at the bottom of oven   


We use a glass of 5 mm thickness, glass should be tempered for taking advantage of good toughness and there should be smooth edges around the glass as we slide this glass over the tip of oven


We also fix a thermometer magnetic in order to record the temperature and we also.

Provide an aluminum rectangular grill for easily placement of foods
We can use our solar oven in sun light & can secure 100 to 175 degree centigrade

Life cycle analysis

In following figure we will be able to understand the cycle analysis light duty solar oven.

Solar oven for heavy duty will be made by such products those are recyclable easily. If we look the whole concept behind making solar oven, we will realize that it’s less costly and more importantly that we are not using fossil fuels those are quite dangerous for environment. So the idea to make a solar oven will be environmental friendly as well as economical also.

I will request to all my readers to contribute in this article by giving their valuable feedback in comment box to improve this article i.e. How to make light duty solar oven.

Do you have suggestions? Please comment in comment box.
